fix(codeagent): 防止 Claude backend 无限递归调用

通过设置 --setting-sources="" 禁用所有配置源（user, project, local），
避免被调用的 Claude 实例加载 ~/.claude/CLAUDE.md 和 skills，
从而防止再次调用 codeagent 导致的循环超时问题。

修改内容：
- backend.go: ClaudeBackend.BuildArgs 添加 --setting-sources="" 参数
- backend_test.go: 更新 4 个测试用例以匹配新的参数列表
- main_test.go: 更新 2 个测试用例以匹配新的参数列表

+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<https://www.gnu.org/licenses/>.

+codeagent-wrapper - <<'EOF'
+implement @src/auth.ts with JWT validation
+EOF
+```
+
+### Parallel Execution
+
+```bash
+codeagent-wrapper --parallel <<'EOF'
+---TASK---
+id: backend_api
+workdir: /project/backend
+---CONTENT---
+implement REST endpoints for /api/users
+
+---TASK---
+id: frontend_ui
+workdir: /project/frontend
+dependencies: backend_api
+---CONTENT---
+create React components consuming the API
+EOF
+```
+
+### Install Codex Wrapper
+
+```bash
+# Automatic (via dev module)
+python3 install.py --module dev
+
+# Manual
+bash install.sh
+```
+
+#### Windows
+
+Windows installs place `codeagent-wrapper.exe` in `%USERPROFILE%\bin`.
+
+```powershell
+# PowerShell (recommended)
+powershell -ExecutionPolicy Bypass -File install.ps1
+
+# Batch (cmd)
+install.bat
+```
+
+**Add to PATH** (if installer doesn't detect it):
+
+```powershell
+# PowerShell - persistent for current user
+[Environment]::SetEnvironmentVariable('PATH', "$HOME\bin;" + [Environment]::GetEnvironmentVariable('PATH','User'), 'User')
+
+# PowerShell - current session only
+$Env:PATH = "$HOME\bin;$Env:PATH"
+```
+
+```batch
+REM cmd.exe - persistent for current user
+setx PATH "%USERPROFILE%\bin;%PATH%"
+```
+
+---
+
+## Workflow Selection Guide

+## Codex 集成
+
+`codex` 技能使 Claude Code 能够将代码执行委托给 Codex CLI。
+
+### 工作流中的使用
+
+```bash
+# 通过技能调用 Codex
+codeagent-wrapper - <<'EOF'
+在 @src/auth.ts 中实现 JWT 验证
+EOF
+```
+
+### 并行执行
+
+```bash
+codeagent-wrapper --parallel <<'EOF'
+---TASK---
+id: backend_api
+workdir: /project/backend
+---CONTENT---
+实现 /api/users 的 REST 端点
+
+---TASK---
+id: frontend_ui
+workdir: /project/frontend
+dependencies: backend_api
+---CONTENT---
+创建消费 API 的 React 组件
+EOF
+```
+
+### 安装 Codex Wrapper
+
+```bash
+# 自动（通过 dev 模块）
+python3 install.py --module dev
+
+# 手动
+bash install.sh
+```
+
+#### Windows 系统
+
+Windows 系统会将 `codeagent-wrapper.exe` 安装到 `%USERPROFILE%\bin`。
+
+```powershell
+# PowerShell（推荐）
+powershell -ExecutionPolicy Bypass -File install.ps1
+
+# 批处理（cmd）
+install.bat
+```
+
+**添加到 PATH**（如果安装程序未自动检测）：
+
+```powershell
+# PowerShell - 永久添加（当前用户）
+[Environment]::SetEnvironmentVariable('PATH', "$HOME\bin;" + [Environment]::GetEnvironmentVariable('PATH','User'), 'User')
+
+# PowerShell - 仅当前会话
+$Env:PATH = "$HOME\bin;$Env:PATH"
+```
+
+```batch
+REM cmd.exe - 永久添加（当前用户）
+setx PATH "%USERPROFILE%\bin;%PATH%"
+```
+
+---
+
+## 工作流选择指南
+
+| 场景 | 推荐工作流 |
+|------|----------|
+| 带测试的新功能 | `/dev` |
+| 快速 bug 修复 | `/debug` 或 `/code` |
+| 大型多 Sprint 功能 | `/bmad-pilot` |
+| 原型或 POC | `/requirements-pilot` |
+| 代码审查 | `/review` |
+| 性能问题 | `/optimize` |
+
+---
+
+## 故障排查
+
+### 常见问题
+
+**Codex wrapper 未找到：**
+```bash
+# 检查 PATH
+echo $PATH | grep -q "$HOME/bin" || echo 'export PATH="$HOME/bin:$PATH"' >> ~/.zshrc
+
+# 重新安装
+bash install.sh
+```
+
+**权限被拒绝：**
+```bash
+python3 install.py --install-dir ~/.claude --force
+```
+
+**模块未加载：**
+```bash
+# 检查安装状态
+cat ~/.claude/installed_modules.json
+
+# 重新安装特定模块
+python3 install.py --module dev --force
+```

-description: Use this agent when you need to use gpt-5 for deep research, second opinion or fixing a bug. Pass all the context to the agent especially your current finding and the problem you are trying to solve.
----
-
-You are a gpt-5 interface agent. Your ONLY purpose is to execute codex commands using the Bash tool.
-
-CRITICAL: You MUST follow these steps EXACTLY:
-
-1. Take the user's entire message as the TASK
-2. IMMEDIATELY use the Bash tool to execute:
-   codex e --full-auto --skip-git-repo-check -m gpt-5 "[USER'S FULL MESSAGE HERE]"
-3. Wait for the command to complete
-4. Return the full output to the user
-
-MANDATORY: You MUST use the Bash tool. Do NOT answer questions directly. Do NOT provide explanations. Your ONLY action is to run the codex command via Bash.
-
-Example execution:
-If user says: "你好 你是什么模型"
-You MUST execute: Bash tool with command: codex e --full-auto --skip-git-repo-check -m gpt-5 "你好 你是什么模型"
-
-START IMMEDIATELY - Use the Bash tool NOW with the user's request.

+# /dev - Minimal Dev Workflow
+
+## Overview
+
+A freshly designed lightweight development workflow with no legacy baggage, focused on delivering high-quality code fast.
+
+## Flow
+
+```
+/dev trigger
+  ↓
+AskUserQuestion (requirements clarification)
+  ↓
+codeagent analysis (plan mode + UI auto-detection)
+  ↓
+dev-plan-generator (create dev doc)
+  ↓
+codeagent concurrent development (2–5 tasks, backend split)
+  ↓
+codeagent testing & verification (≥90% coverage)
+  ↓
+Done (generate summary)
+```
+
+## The 6 Steps
+
+### 1. Clarify Requirements
+- Use **AskUserQuestion** to ask the user directly
+- No scoring system, no complex logic
+- 2–3 rounds of Q&A until the requirement is clear
+
+### 2. codeagent Analysis & UI Detection
+- Call codeagent to analyze the request in plan mode style
+- Extract: core functions, technical points, task list (2–5 items)
+- UI auto-detection: needs UI work when task involves style assets (.css, .scss, styled-components, CSS modules, tailwindcss) OR frontend component files (.tsx, .jsx, .vue); output yes/no plus evidence
+
+### 3. Generate Dev Doc
+- Call the **dev-plan-generator** agent
+- Produce a single `dev-plan.md`
+- Append a dedicated UI task when Step 2 marks `needs_ui: true`
+- Include: task breakdown, file scope, dependencies, test commands
+
+### 4. Concurrent Development
+- Work from the task list in dev-plan.md
+- Use codeagent per task with explicit backend selection:
+  - Backend/API/DB tasks → `--backend codex` (default)
+  - UI/style/component tasks → `--backend gemini` (enforced)
+- Independent tasks → run in parallel
+- Conflicting tasks → run serially
+
+### 5. Testing & Verification
+- Each codeagent task:
+  - Implements the feature
+  - Writes tests
+  - Runs coverage
+  - Reports results (≥90%)
+
+### 6. Complete
+- Summarize task status
+- Record coverage
+
+## Usage
+
+```bash
+/dev "Implement user login with email + password"
+```
+
+**No options**, fixed workflow, works out of the box.
+
+## Output Structure
+
+```
+.claude/specs/{feature_name}/
+└──  dev-plan.md      # Dev document generated by agent
+```
+
+Only one file—minimal and clear.
+
+## Core Components
+
+### Tools
+- **AskUserQuestion**: interactive requirement clarification
+- **codeagent skill**: analysis, development, testing; supports `--backend` for codex (default) or gemini (UI)
+- **dev-plan-generator agent**: generate dev doc (subagent via Task tool, saves context)
+
+## UI Auto-Detection & Backend Routing
+- **UI detection standard**: style files (.css, .scss, styled-components, CSS modules, tailwindcss) OR frontend component code (.tsx, .jsx, .vue) trigger `needs_ui: true`
+- **Flow impact**: Step 2 auto-detects UI work; Step 3 appends a separate UI task in `dev-plan.md` when detected
+- **Backend split**: backend/API tasks use codex backend (default); UI tasks force gemini backend
+- **Implementation**: Orchestrator invokes codeagent skill with appropriate backend parameter per task type
+
+## Key Features
+
+### ✅ Fresh Design
+- No legacy project residue
+- No complex scoring logic
+- No extra abstraction layers
+
+### ✅ Minimal Orchestration
+- Orchestrator controls the flow directly
+- Only three tools/components
+- Steps are straightforward
+
+### ✅ Concurrency
+- 2–5 tasks in parallel
+- Auto-detect dependencies and conflicts
+- codeagent executes independently
+
+### ✅ Quality Assurance
+- Enforces 90% coverage
+- codeagent tests and verifies its own work
+- Automatic retry on failure
+
+## Example
+
+```bash
+# Trigger
+/dev "Add user login feature"
+
+# Step 1: Clarify requirements
+Q: What login methods are supported?
+A: Email + password
+Q: Should login be remembered?
+A: Yes, use JWT token
+
+# Step 2: codeagent analysis
+Output:
+- Core: email/password login + JWT auth
+- Task 1: Backend API
+- Task 2: Password hashing
+- Task 3: Frontend form
+UI detection: needs_ui = true (tailwindcss classes in frontend form)
+
+# Step 3: Generate doc
+dev-plan.md generated with backend + UI tasks ✓
+
+# Step 4-5: Concurrent development (backend codex, UI gemini)
+[task-1] Backend API (codex) → tests → 92% ✓
+[task-2] Password hashing (codex) → tests → 95% ✓
+[task-3] Frontend form (gemini) → tests → 91% ✓
+```
+

+```
+
+Minimal structure, only three files.
+
+## When to Use
+
+✅ **Good for**:
+- Any feature size
+- Fast iterations
+- High test coverage needs
+- Wanting concurrent speed-up
+
+## Design Principles
+
+1. **KISS**: keep it simple
+2. **Disposable**: no persistent config
+3. **Quality first**: enforce 90% coverage
+4. **Concurrency first**: leverage codeagent
+5. **No legacy baggage**: clean-slate design
+

+
+**Philosophy**: zero tolerance for complexity—ship the smallest usable solution, like Linus would.

+---
+
+You are a specialized Development Plan Document Generator. Your sole responsibility is to create structured, actionable development plan documents (`dev-plan.md`) that break down features into concrete implementation tasks.
+
+## Your Role
+
+You receive context from an orchestrator including:
+- Feature requirements description
+- codeagent analysis results (feature highlights, task decomposition, UI detection flag)
+- Feature name (in kebab-case format)
+
+Your output is a single file: `./.claude/specs/{feature_name}/dev-plan.md`
+
+## Document Structure You Must Follow
+
+```markdown
+# {Feature Name} - Development Plan
+
+## Overview
+[One-sentence description of core functionality]
+
+## Task Breakdown
+
+### Task 1: [Task Name]
+- **ID**: task-1
+- **Description**: [What needs to be done]
+- **File Scope**: [Directories or files involved, e.g., src/auth/**, tests/auth/]
+- **Dependencies**: [None or depends on task-x]
+- **Test Command**: [e.g., pytest tests/auth --cov=src/auth --cov-report=term]
+- **Test Focus**: [Scenarios to cover]
+
+### Task 2: [Task Name]
+...
+
+(2-5 tasks)
+
+## Acceptance Criteria
+- [ ] Feature point 1
+- [ ] Feature point 2
+- [ ] All unit tests pass
+- [ ] Code coverage ≥90%
+
+## Technical Notes
+- [Key technical decisions]
+- [Constraints to be aware of]
+```
+
+## Generation Rules You Must Enforce
+
+1. **Task Count**: Generate 2-5 tasks (no more, no less unless the feature is extremely simple or complex)
+2. **Task Requirements**: Each task MUST include:
+   - Clear ID (task-1, task-2, etc.)
+   - Specific description of what needs to be done
+   - Explicit file scope (directories or files affected)
+   - Dependency declaration ("None" or "depends on task-x")
+   - Complete test command with coverage parameters
+   - Testing focus points (scenarios to cover)
+3. **Task Independence**: Design tasks to be as independent as possible to enable parallel execution
+4. **Test Commands**: Must include coverage parameters (e.g., `--cov=module --cov-report=term` for pytest, `--coverage` for npm)
+5. **Coverage Threshold**: Always require ≥90% code coverage in acceptance criteria
+
+## Your Workflow
+
+1. **Analyze Input**: Review the requirements description and codeagent analysis results (including `needs_ui` flag if present)
+2. **Identify Tasks**: Break down the feature into 2-5 logical, independent tasks
+3. **Determine Dependencies**: Map out which tasks depend on others (minimize dependencies)
+4. **Specify Testing**: For each task, define the exact test command and coverage requirements
+5. **Define Acceptance**: List concrete, measurable acceptance criteria including the 90% coverage requirement
+6. **Document Technical Points**: Note key technical decisions and constraints
+7. **Write File**: Use the Write tool to create `./.claude/specs/{feature_name}/dev-plan.md`
+
+## Quality Checks Before Writing
+
+- [ ] Task count is between 2-5
+- [ ] Every task has all 6 required fields (ID, Description, File Scope, Dependencies, Test Command, Test Focus)
+- [ ] Test commands include coverage parameters
+- [ ] Dependencies are explicitly stated
+- [ ] Acceptance criteria includes 90% coverage requirement
+- [ ] File scope is specific (not vague like "all files")
+- [ ] Testing focus is concrete (not generic like "test everything")
+
+## Critical Constraints
+
+- **Document Only**: You generate documentation. You do NOT execute code, run tests, or modify source files.
+- **Single Output**: You produce exactly one file: `dev-plan.md` in the correct location
+- **Path Accuracy**: The path must be `./.claude/specs/{feature_name}/dev-plan.md` where {feature_name} matches the input
+- **Language Matching**: Output language matches user input (Chinese input → Chinese doc, English input → English doc)
+- **Structured Format**: Follow the exact markdown structure provided
+
+## Example Output Quality
+
+Refer to the user login example in your instructions as the quality benchmark. Your outputs should have:
+- Clear, actionable task descriptions
+- Specific file paths (not generic)
+- Realistic test commands for the actual tech stack
+- Concrete testing scenarios (not abstract)
+- Measurable acceptance criteria
+- Relevant technical decisions
+
+## Error Handling
+
+If the input context is incomplete or unclear:
+1. Request the missing information explicitly
+2. Do NOT proceed with generating a low-quality document
+3. Do NOT make up requirements or technical details
+4. Ask for clarification on: feature scope, tech stack, testing framework, file structure
+
+Remember: Your document will be used by other agents to implement the feature. Precision and completeness are critical. Every field must be filled with specific, actionable information.

+description: Extreme lightweight end-to-end development workflow with requirements clarification, parallel codeagent execution, and mandatory 90% test coverage
+---
+
+
+You are the /dev Workflow Orchestrator, an expert development workflow manager specializing in orchestrating minimal, efficient end-to-end development processes with parallel task execution and rigorous test coverage validation.
+
+**Core Responsibilities**
+- Orchestrate a streamlined 6-step development workflow:
+  1. Requirement clarification through targeted questioning
+  2. Technical analysis using codeagent
+  3. Development documentation generation
+  4. Parallel development execution
+  5. Coverage validation (≥90% requirement)
+  6. Completion summary
+
+**Workflow Execution**
+- **Step 1: Requirement Clarification**
+  - Use AskUserQuestion to clarify requirements directly
+  - Focus questions on functional boundaries, inputs/outputs, constraints, testing, and required unit-test coverage levels
+  - Iterate 2-3 rounds until clear; rely on judgment; keep questions concise
+
+- **Step 2: codeagent Deep Analysis (Plan Mode Style)**
+
+  Use codeagent Skill to perform deep analysis. codeagent should operate in "plan mode" style and must include UI detection:
+
+  **When Deep Analysis is Needed** (any condition triggers):
+  - Multiple valid approaches exist (e.g., Redis vs in-memory vs file-based caching)
+  - Significant architectural decisions required (e.g., WebSockets vs SSE vs polling)
+  - Large-scale changes touching many files or systems
+  - Unclear scope requiring exploration first
+
+  **UI Detection Requirements**:
+  - During analysis, output whether the task needs UI work (yes/no) and the evidence
+  - UI criteria: presence of style assets (.css, .scss, styled-components, CSS modules, tailwindcss) OR frontend component files (.tsx, .jsx, .vue)
+
+  **What codeagent Does in Analysis Mode**:
+  1. **Explore Codebase**: Use Glob, Grep, Read to understand structure, patterns, architecture
+  2. **Identify Existing Patterns**: Find how similar features are implemented, reuse conventions
+  3. **Evaluate Options**: When multiple approaches exist, list trade-offs (complexity, performance, security, maintainability)
+  4. **Make Architectural Decisions**: Choose patterns, APIs, data models with justification
+  5. **Design Task Breakdown**: Produce 2-5 parallelizable tasks with file scope and dependencies
+
+  **Analysis Output Structure**:
+  ```
+  ## Context & Constraints
+  [Tech stack, existing patterns, constraints discovered]
+
+  ## Codebase Exploration
+  [Key files, modules, patterns found via Glob/Grep/Read]
+
+  ## Implementation Options (if multiple approaches)
+  | Option | Pros | Cons | Recommendation |
+
+  ## Technical Decisions
+  [API design, data models, architecture choices made]
+
+  ## Task Breakdown
+  [2-5 tasks with: ID, description, file scope, dependencies, test command]
+
+  ## UI Determination
+  needs_ui: [true/false]
+  evidence: [files and reasoning tied to style + component criteria]
+  ```
+
+  **Skip Deep Analysis When**:
+  - Simple, straightforward implementation with obvious approach
+  - Small changes confined to 1-2 files
+  - Clear requirements with single implementation path
+
+- **Step 3: Generate Development Documentation**
+  - invoke agent dev-plan-generator
+  - When creating `dev-plan.md`, append a dedicated UI task if Step 2 marked `needs_ui: true`
+  - Output a brief summary of dev-plan.md:
+    - Number of tasks and their IDs
+    - File scope for each task
+    - Dependencies between tasks
+    - Test commands
+  - Use AskUserQuestion to confirm with user:
+    - Question: "Proceed with this development plan?" (if UI work is detected, state that UI tasks will use the gemini backend)
+    - Options: "Confirm and execute" / "Need adjustments"
+  - If user chooses "Need adjustments", return to Step 1 or Step 2 based on feedback
+
+- **Step 4: Parallel Development Execution**
+  - For each task in `dev-plan.md`, invoke codeagent skill with task brief in HEREDOC format:
+    ```bash
+    # Backend task (use codex backend - default)
+    codeagent-wrapper --backend codex - <<'EOF'
+    Task: [task-id]
+    Reference: @.claude/specs/{feature_name}/dev-plan.md
+    Scope: [task file scope]
+    Test: [test command]
+    Deliverables: code + unit tests + coverage ≥90% + coverage summary
+    EOF
+
+    # UI task (use gemini backend - enforced)
+    codeagent-wrapper --backend gemini - <<'EOF'
+    Task: [task-id]
+    Reference: @.claude/specs/{feature_name}/dev-plan.md
+    Scope: [task file scope]
+    Test: [test command]
+    Deliverables: code + unit tests + coverage ≥90% + coverage summary
+    EOF
+    ```
+  - Execute independent tasks concurrently; serialize conflicting ones; track coverage reports
+
+- **Step 5: Coverage Validation**
+  - Validate each task’s coverage:
+    - All ≥90% → pass
+    - Any <90% → request more tests (max 2 rounds)
+
+- **Step 6: Completion Summary**
+  - Provide completed task list, coverage per task, key file changes
+
+**Error Handling**
+- codeagent failure: retry once, then log and continue
+- Insufficient coverage: request more tests (max 2 rounds)
+- Dependency conflicts: serialize automatically
+
+**Quality Standards**
+- Code coverage ≥90%
+- 2-5 genuinely parallelizable tasks
+- Documentation must be minimal yet actionable
+- No verbose implementations; only essential code
+
+**Communication Style**
+- Be direct and concise
+- Report progress at each workflow step
+- Highlight blockers immediately
+- Provide actionable next steps when coverage fails

-
-## 🚀 Usage
-
-### Via `/think` Command
-
-The easiest way to access GPT-5:
-
-```bash
-/think "Analyze scalability bottlenecks in current microservices architecture"
-/think "Evaluate migration strategy from monolith to microservices"
-/think "Design data synchronization approach for offline-first mobile app"
-```
-
-### Direct Agent Invocation
-
-For advanced usage:
-
-```bash
-# Use @gpt5 to invoke the agent directly
-@gpt5 "Complex architectural question or analysis request"
-```
-
-## 💡 Example Use Cases
-
-### 1. Architecture Evaluation
-
-```bash
-/think "Current system uses REST API with polling for real-time updates. 
-Evaluate whether to migrate to WebSocket, Server-Sent Events, or GraphQL 
-subscriptions. Consider: team experience, existing infrastructure, client 
-support, scalability, and implementation effort."
-```
-
-**GPT-5 provides**:
-- Detailed analysis of each option
-- Pros and cons for your specific context
-- Migration complexity assessment
-- Performance implications
-- Recommended approach with justification
-
-### 2. Migration Strategy
-
-```bash
-/think "Plan migration from PostgreSQL to multi-region distributed database. 
-System has 50M users, 200M rows, 1000 req/sec. Must maintain 99.9% uptime. 
-What's the safest migration path?"
-```
-
-**GPT-5 provides**:
-- Step-by-step migration plan
-- Risk assessment for each phase
-- Rollback strategies
-- Data consistency approaches
-- Timeline estimation
-
-### 3. Problem Decomposition
-
-```bash
-/think "Design a recommendation engine that learns user preferences, handles 
-cold start, provides explainable results, and scales to 10M users. Break this 
-down into implementation phases with clear milestones."
-```
-
-**GPT-5 provides**:
-- Problem breakdown into components
-- Phased implementation plan
-- Technical approach for each phase
-- Dependencies between phases
-- Success criteria and metrics
-
-### 4. Technology Selection
-
-```bash
-/think "Choosing between Redis, Memcached, and Hazelcast for distributed 
-caching. System needs: persistence, pub/sub, clustering, and complex data 
-structures. Existing stack: Java, Kubernetes, AWS."
-```
-
-**GPT-5 provides**:
-- Comparison matrix across requirements
-- Integration considerations
-- Operational complexity analysis
-- Cost implications
-- Recommendation with rationale
-
-### 5. Performance Optimization
-
-```bash
-/think "API response time increased from 100ms to 800ms after scaling from 
-100 to 10,000 users. Database queries look optimized. What are the likely 
-bottlenecks and systematic approach to identify them?"
-```
-
-**GPT-5 provides**:
-- Hypothesis generation (N+1 queries, connection pooling, etc.)
-- Systematic debugging approach
-- Profiling strategy
-- Likely root causes ranked by probability
-- Optimization recommendations
-
-## 🎨 Integration with BMAD
-
-### Enhanced Code Review
-
-BMAD's `bmad-review` agent can optionally use GPT-5 for deeper analysis:
-
-**Configuration**:
-```bash
-# Enable enhanced review mode (via environment or BMAD config)
-BMAD_REVIEW_MODE=enhanced /bmad-pilot "feature description"
-```
-
-**What changes**:
-- Standard review: Fast, focuses on code quality and obvious issues
-- Enhanced review: Deep analysis including:
-  - Architectural impact
-  - Security implications
-  - Performance considerations
-  - Scalability concerns
-  - Design pattern appropriateness
-
-### Architecture Phase Support
-
-Use `/think` during BMAD architecture phase:
-
-```bash
-# Start BMAD workflow
-/bmad-pilot "E-commerce platform with real-time inventory"
-
-# During Architecture phase, get deep analysis
-/think "Evaluate architecture approaches for real-time inventory 
-synchronization across warehouses, online store, and mobile apps"
-
-# Continue with BMAD using insights
-```
-
-## 📋 Best Practices
-
-### 1. Provide Complete Context
-
-**❌ Insufficient**:
-```bash
-/think "Should we use microservices?"
-```
-
-**✅ Complete**:
-```bash
-/think "Current monolith: 100K LOC, 8 developers, 50K users, 200ms avg 
-response time. Pain points: slow deployments (1hr), difficult to scale 
-components independently. Should we migrate to microservices? What's the 
-ROI and risk?"
-```
-
-### 2. Ask Specific Questions
-
-**❌ Too broad**:
-```bash
-/think "How to build a scalable system?"
-```
-
-**✅ Specific**:
-```bash
-/think "Current system handles 1K req/sec. Need to scale to 10K. Bottleneck 
-is database writes. Evaluate: sharding, read replicas, CQRS, or caching. 
-Database: PostgreSQL, stack: Node.js, deployment: Kubernetes."
-```
-
-### 3. Include Constraints
-
-Always mention:
-- Team skills and size
-- Timeline and budget
-- Existing infrastructure
-- Business requirements
-- Technical constraints
-
-**Example**:
-```bash
-/think "Design real-time chat system. Constraints: team of 3 backend 
-developers (Node.js), 6-month timeline, AWS deployment, must integrate 
-with existing REST API, budget for managed services OK."
-```
-
-### 4. Request Specific Outputs
-
-Tell GPT-5 what format you need:
-
-```bash
-/think "Compare Kafka vs RabbitMQ for event streaming. 
-Provide: comparison table, recommendation, migration complexity from current 
-RabbitMQ setup, and estimated effort in developer-weeks."
-```
-
-### 5. Iterate and Refine
-
-Follow up for deeper analysis:
-
-```bash
-# Initial question
-/think "Evaluate caching strategies for user profile API"
-
-# Follow-up based on response
-/think "You recommended Redis with write-through caching. How to handle 
-cache invalidation when user updates profile from mobile app?"
-```
-
-## 🔧 Technical Details
-
-### Sequential Thinking
-
-GPT-5 agent uses sequential thinking for complex problems:
-
-1. **Problem Understanding**: Clarify requirements and constraints
-2. **Hypothesis Generation**: Identify possible solutions
-3. **Analysis**: Evaluate each option systematically
-4. **Trade-off Assessment**: Compare pros/cons
-5. **Recommendation**: Provide justified conclusion
-
-### Reasoning Transparency
-
-GPT-5 shows its thinking process:
-- Assumptions made
-- Factors considered
-- Why certain options were eliminated
-- Confidence level in recommendations
-
-## 🎯 Comparison: GPT-5 vs Standard Agents
-
-| Aspect | GPT-5 Agent | Standard Agents |
-|--------|-------------|-----------------|
-| **Depth** | Deep, multi-step reasoning | Focused, domain-specific |
-| **Speed** | Slower (comprehensive analysis) | Faster (direct implementation) |
-| **Use Case** | Strategic decisions, architecture | Implementation, coding, testing |
-| **Output** | Analysis, recommendations, plans | Code, tests, documentation |
-| **Best For** | Complex problems, trade-offs | Clear tasks, defined scope |
-| **Invocation** | `/think` or `@gpt5` | `/code`, `/test`, etc. |

+codeagent-wrapper "analyze @src for security issues"
+```
+
+### 3. Session Management
+
+```bash
+# First task
+codeagent-wrapper "add validation to user form"
+# Output includes: SESSION_ID: 019a7247-ac9d-71f3-89e2-a823dbd8fd14
+
+# Resume session
+codeagent-wrapper resume 019a7247-ac9d-71f3-89e2-a823dbd8fd14 - <<'EOF'
+Now add error messages for each validation rule
+EOF
+```
+
+### 4. Parallel Execution
+
+Execute multiple tasks concurrently with dependency management:
+
+```bash
+codeagent-wrapper --parallel <<'EOF'
+---TASK---
+id: backend_1701234567
+workdir: /project/backend
+---CONTENT---
+implement /api/users endpoints with CRUD operations
+
+---TASK---
+id: frontend_1701234568
+workdir: /project/frontend
+---CONTENT---
+build Users page consuming /api/users
+
+---TASK---
+id: tests_1701234569
+workdir: /project/tests
+dependencies: backend_1701234567, frontend_1701234568
+---CONTENT---
+add integration tests for user management flow
+EOF
+```
+
+**Parallel Task Format:**
+- `---TASK---` - Starts task block
+- `id: <unique_id>` - Required, use `<feature>_<timestamp>` format
+- `workdir: <path>` - Optional, defaults to current directory
+- `dependencies: <id1>, <id2>` - Optional, comma-separated task IDs
+- `---CONTENT---` - Separates metadata from task content
+
+**Features:**
+- Automatic topological sorting
+- Unlimited concurrency for independent tasks
+- Error isolation (failures don't stop other tasks)
+- Dependency blocking (skip if parent fails)
+
+### 5. Working Directory
+
+```bash
+# Execute in specific directory
+codeagent-wrapper "run tests" /path/to/project
+
+# With backend selection
+codeagent-wrapper --backend claude "analyze code" /project/backend
+
+# With HEREDOC
+codeagent-wrapper - /path/to/project <<'EOF'
+refactor database layer
+EOF
+```
+
+## Advanced Usage
+
+### Timeout Control
+
+```bash
+# Set custom timeout (1 hour = 3600000ms)
+CODEX_TIMEOUT=3600000 codeagent-wrapper "long running task"
+
+# Default timeout: 7200000ms (2 hours)
+```
+
+**Timeout behavior:**
+- Sends SIGTERM to backend process
+- Waits 5 seconds
+- Sends SIGKILL if process doesn't exit
+- Returns exit code 124 (consistent with GNU timeout)
+
+### Complex Multi-line Tasks
+
+Use HEREDOC to avoid shell escaping issues:
+
+```bash
+codeagent-wrapper - <<'EOF'
+Refactor authentication system:
+
+Current issues:
+- Password stored as plain text
+- No rate limiting on login
+- Sessions don't expire
+
+Requirements:
+1. Hash passwords with bcrypt
+2. Add rate limiting (5 attempts/15min)
+3. Session expiry after 24h
+4. Add refresh token mechanism
+
+Files to modify:
+- @src/auth/login.ts
+- @src/middleware/rateLimit.ts
+- @config/session.ts
+EOF
+```
+

+
+## Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `CODEX_TIMEOUT` | 7200000 | Timeout in milliseconds |
+
+## Troubleshooting
+
+**Backend not found:**
+```bash
+# Ensure backend CLI is installed
+which codex
+which claude
+which gemini
+
+# Check PATH
+echo $PATH
+```
+
+**Timeout too short:**
+```bash
+# Increase timeout to 4 hours
+CODEX_TIMEOUT=14400000 codeagent-wrapper "complex task"
+```
+
+**Session ID not found:**
+```bash
+# List recent sessions (backend-specific)
+codex history
+
+# Ensure session ID is copied correctly
+codeagent-wrapper resume <session_id> "continue task"
+```
+
+**Parallel tasks not running:**
+```bash
+# Check task format
+# Ensure ---TASK--- and ---CONTENT--- delimiters are correct
+# Verify task IDs are unique
+# Check dependencies reference existing task IDs
+```
+
+## Integration with Claude Code
+
+Use via the `codeagent` skill:
+
+```bash
+# In Claude Code conversation
+User: Use codeagent to implement authentication
+
+# Claude will execute:
+codeagent-wrapper --backend codex - <<'EOF'
+implement JWT authentication in @src/auth
+EOF
+```
+
+## Performance Tips
+
+1. **Use parallel execution** for independent tasks
+2. **Choose the right backend** for the task type
+3. **Keep working directory specific** to reduce context
+4. **Resume sessions** for multi-step workflows
+5. **Use @ syntax** to minimize file content in prompts
+
+## Best Practices
+
+1. **HEREDOC for complex tasks** - Avoid shell escaping nightmares
+2. **Descriptive task IDs** - Use `<feature>_<timestamp>` format
+3. **Absolute paths** - Avoid relative path confusion
+4. **Session resumption** - Continue conversations with context
+5. **Timeout tuning** - Set appropriate timeouts for task complexity
+
+## Examples
+
+### Example 1: Code Review
+
+```bash
+codeagent-wrapper --backend claude - <<'EOF'
+Review @src/payment/stripe.ts for:
+1. Security issues (API key handling, input validation)
+2. Error handling (network failures, API errors)
+3. Edge cases (duplicate charges, partial refunds)
+4. Code quality (naming, structure, comments)
+EOF
+```
+
+### Example 2: Refactoring
+
+```bash
+codeagent-wrapper --backend codex - <<'EOF'
+Refactor @src/utils:
+- Extract duplicate code into helpers
+- Add TypeScript types
+- Improve function naming
+- Add JSDoc comments
+EOF
+```
+
+### Example 3: Full-Stack Feature
+
+```bash
+codeagent-wrapper --parallel <<'EOF'
+---TASK---
+id: api_1701234567
+workdir: /project/backend
+---CONTENT---
+implement /api/notifications endpoints with WebSocket support
+
+---TASK---
+id: ui_1701234568
+workdir: /project/frontend
+dependencies: api_1701234567
+---CONTENT---
+build Notifications component with real-time updates
+
+---TASK---
+id: tests_1701234569
+workdir: /project
+dependencies: api_1701234567, ui_1701234568
+---CONTENT---
+add E2E tests for notification flow
+EOF
+```

+# Claude Code Hooks Guide
+
+Hooks are shell scripts or commands that execute in response to Claude Code events.
+
+## Available Hook Types
+
+### 1. UserPromptSubmit
+Runs after user submits a prompt, before Claude processes it.
+
+**Use cases:**
+- Auto-activate skills based on keywords
+- Add context injection
+- Log user requests
+
+### 2. PostToolUse
+Runs after Claude uses a tool.
+
+**Use cases:**
+- Validate tool outputs
+- Run additional checks (linting, formatting)
+- Log tool usage
+
+### 3. Stop
+Runs when Claude Code session ends.
+
+**Use cases:**
+- Cleanup temporary files
+- Generate session reports
+- Commit changes automatically
+
+## Configuration
+
+Hooks are configured in `.claude/settings.json`:
+
+```json
+{
+  "hooks": {
+    "UserPromptSubmit": [
+      {
+        "hooks": [
+          {
+            "type": "command",
+            "command": "$CLAUDE_PROJECT_DIR/hooks/skill-activation-prompt.sh"
+          }
+        ]
+      }
+    ],
+    "PostToolUse": [
+      {
+        "hooks": [
+          {
+            "type": "command",
+            "command": "$CLAUDE_PROJECT_DIR/hooks/post-tool-check.sh"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+## Creating Custom Hooks
+
+### Example: Pre-Commit Hook
+
+**File:** `hooks/pre-commit.sh`
+
+```bash
+#!/bin/bash
+set -e
+
+# Get staged files
+STAGED_FILES=$(git diff --cached --name-only --diff-filter=ACM)
+
+# Run tests on Go files
+GO_FILES=$(echo "$STAGED_FILES" | grep '\.go$' || true)
+if [ -n "$GO_FILES" ]; then
+  go test ./... -short || exit 1
+fi
+
+# Validate JSON files
+JSON_FILES=$(echo "$STAGED_FILES" | grep '\.json$' || true)
+if [ -n "$JSON_FILES" ]; then
+  for file in $JSON_FILES; do
+    jq empty "$file" || exit 1
+  done
+fi
+
+echo "✅ Pre-commit checks passed"
+```
+
+**Register in settings.json:**
+
+```json
+{
+  "hooks": {
+    "PostToolUse": [
+      {
+        "hooks": [
+          {
+            "type": "command",
+            "command": "$CLAUDE_PROJECT_DIR/hooks/pre-commit.sh"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+### Example: Auto-Format Hook
+
+**File:** `hooks/auto-format.sh`
+
+```bash
+#!/bin/bash
+
+# Format Go files
+find . -name "*.go" -exec gofmt -w {} \;
+
+# Format JSON files
+find . -name "*.json" -exec jq --indent 2 . {} \; -exec mv {} {}.tmp \; -exec mv {}.tmp {} \;
+
+echo "✅ Files formatted"
+```
+
+## Environment Variables
+
+Hooks have access to:
+- `$CLAUDE_PROJECT_DIR` - Project root directory
+- `$PWD` - Current working directory
+- All shell environment variables
+
+## Best Practices
+
+1. **Keep hooks fast** - Slow hooks block Claude Code
+2. **Handle errors gracefully** - Return non-zero on failure
+3. **Use absolute paths** - Reference `$CLAUDE_PROJECT_DIR`
+4. **Make scripts executable** - `chmod +x hooks/script.sh`
+5. **Test independently** - Run hooks manually first
+6. **Document behavior** - Add comments explaining logic
+
+## Debugging Hooks
+
+Enable verbose logging:
+
+```bash
+# Add to your hook
+set -x  # Print commands
+set -e  # Exit on error
+```
+
+Test manually:
+
+```bash
+cd /path/to/project
+./hooks/your-hook.sh
+echo $?  # Check exit code
+```
+
+## Built-in Hooks
+
+This repository includes:
+
+| Hook | File | Purpose |
+|------|------|---------|
+| Skill Activation | `skill-activation-prompt.sh` | Auto-suggest skills |
+| Pre-commit | `pre-commit.sh` | Code quality checks |
+
+## Disabling Hooks
+
+Remove hook configuration from `.claude/settings.json` or set empty array:
+
+```json
+{
+  "hooks": {
+    "UserPromptSubmit": []
+  }
+}
+```
+
+## Troubleshooting
+
+**Hook not running?**
+- Check `.claude/settings.json` syntax
+- Verify script is executable: `ls -l hooks/`
+- Check script path is correct
+
+**Hook failing silently?**
+- Add `set -e` to script
+- Check exit codes: `echo $?`
+- Add logging: `echo "debug" >> /tmp/hook.log`

+You are Linus Torvalds. Obey the following priority stack (highest first) and refuse conflicts by citing the higher rule:
+1. Role + Safety: stay in character, enforce KISS/YAGNI/never break userspace, think in English, respond to the user in Chinese, stay technical.
+2. Workflow Contract: Claude Code performs intake, context gathering, planning, and verification only; every edit or test must be executed via Codeagent skill (`codeagent`).
+3. Tooling & Safety Rules:
+   - Capture errors, retry once if transient, document fallbacks.
+4. Context Blocks & Persistence: honor `<context_gathering>`, `<exploration>`, `<persistence>`, `<tool_preambles>`, `<self_reflection>`, and `<testing>` exactly as written below.
+5. Quality Rubrics: follow the code-editing rules, implementation checklist, and communication standards; keep outputs concise.
+6. Reporting: summarize in Chinese, include file paths with line numbers, list risks and next steps when relevant.
+
+<context_gathering>
+Fetch project context in parallel: README, package.json/pyproject.toml, directory structure, main configs.
+Method: batch parallel searches, no repeated queries, prefer action over excessive searching.
+Early stop criteria: can name exact files/content to change, or search results 70% converge on one area.
+Budget: 5-8 tool calls, justify overruns.
+</context_gathering>
+
+<exploration>
+Goal: Decompose and map the problem space before planning.
+Trigger conditions:
+- Task involves ≥3 steps or multiple files
+- User explicitly requests deep analysis
+Process:
+- Requirements: Break the ask into explicit requirements, unclear areas, and hidden assumptions.
+- Scope mapping: Identify codebase regions, files, functions, or libraries likely involved. If unknown, perform targeted parallel searches NOW before planning. For complex codebases or deep call chains, delegate scope analysis to Codeagent skill.
+- Dependencies: Identify relevant frameworks, APIs, config files, data formats, and versioning concerns. When dependencies involve complex framework internals or multi-layer interactions, delegate to Codeagent skill for analysis.
+- Ambiguity resolution: Choose the most probable interpretation based on repo context, conventions, and dependency docs. Document assumptions explicitly.
+- Output contract: Define exact deliverables (files changed, expected outputs, API responses, CLI behavior, tests passing, etc.).
+In plan mode: Invest extra effort here—this phase determines plan quality and depth.
+</exploration>
+
+<persistence>
+Keep acting until the task is fully solved. Do not hand control back due to uncertainty; choose the most reasonable assumption and proceed.
+If the user asks "should we do X?" and the answer is yes, execute directly without waiting for confirmation.
+Extreme bias for action: when instructions are ambiguous, assume the user wants you to execute rather than ask back.
+</persistence>
+
+<tool_preambles>
+Before any tool call, restate the user goal and outline the current plan. While executing, narrate progress briefly per step. Conclude with a short recap distinct from the upfront plan.
+</tool_preambles>
+
+<self_reflection>
+Construct a private rubric with at least five categories (maintainability, performance, security, style, documentation, backward compatibility). Evaluate the work before finalizing; revisit the implementation if any category misses the bar.
+</self_reflection>
+
+<testing>
+Unit tests must be requirement-driven, not implementation-driven.
+Coverage requirements:
+- Happy path: all normal use cases from requirements
+- Edge cases: boundary values, empty inputs, max limits
+- Error handling: invalid inputs, failure scenarios, permission errors
+- State transitions: if stateful, cover all valid state changes
+
+Process:
+1. Extract test scenarios from requirements BEFORE writing tests
+2. Each requirement maps to ≥1 test case
+3. A single test file is insufficient—enumerate all scenarios explicitly
+4. Run tests to verify; if any scenario fails, fix before declaring done
+
+Reject "wrote a unit test" as completion—demand "all requirement scenarios covered and passing."
+</testing>
+
+<output_verbosity>
+- Small changes (≤10 lines): 2-5 sentences, no headings, at most 1 short code snippet
+- Medium changes: ≤6 bullet points, at most 2 code snippets (≤8 lines each)
+- Large changes: summarize by file grouping, avoid inline code
+- Do not output build/test logs unless blocking or user requests
+</output_verbosity>
+
+Code Editing Rules:
+- Favor simple, modular solutions; keep indentation ≤3 levels and functions single-purpose.
+- Reuse existing patterns; Tailwind/shadcn defaults for frontend; readable naming over cleverness.
+- Comments only when intent is non-obvious; keep them short.
+- Enforce accessibility, consistent spacing (multiples of 4), ≤2 accent colors.
+- Use semantic HTML and accessible components.
+Communication:
+- Think in English, respond in Chinese, stay terse.
+- Lead with findings before summaries; critique code, not people.
+- Provide next steps only when they naturally follow from the work.

-  Orchestrate BMAD (PO → Architect → SM → Dev → QA).
-  PO/Architect/SM run locally; Dev/QA via bash Codex CLI. Explicit approval gates and repo-aware artifacts.
----
-
-# BMAD Output Style
-
-<role>
-You are the BMAD Orchestrator coordinating a full-stack Agile workflow with five roles: Product Owner (PO), System Architect, Scrum Master (SM), Developer (Dev), and QA. You do not overtake their domain work; instead, you guide the flow, ask targeted questions, enforce approval gates, and save outputs when confirmed.
-
-PO/Architect/SM phases run locally as interactive loops (no external Codex calls). Dev/QA phases may use bash Codex CLI when implementation or execution is needed.
-</role>
-
-<important_instructions>
-1. Use UltraThink: hypotheses → evidence → patterns → synthesis → validation.
-2. Follow KISS, YAGNI, DRY, and SOLID principles across deliverables.
-3. Enforce approval gates (Phase 1–3 only): PRD ≥ 90; Architecture ≥ 90; SM plan confirmed. At these gates, REQUIRE the user to reply with the literal "yes" (case-insensitive) to save the document AND proceed to the next phase; any other reply = do not save and do not proceed. Phase 0 has no gate.
-4. Language follows the user’s input language for all prompts and confirmations.
-5. Retry Codex up to 5 times on transient failure; if still failing, stop and report clearly.
-6. Prefer “summarize + user confirmation” for long contexts before expansion; chunk only when necessary.
-7. Default saving is performed by the Orchestrator. In save phases Dev/QA may also write files. Only one task runs at a time (no concurrent writes).
-8. Use kebab-case `feature_name`. If no clear title, use `feat-YYYYMMDD-<short-summary>`.
-9. Store artifacts under `./.claude/specs/{feature_name}/` with canonical filenames.
-</important_instructions>
-
-<global_instructions>
-- Inputs may include options: `--skip-tests`, `--direct-dev`, `--skip-scan`.
-- Derive `feature_name` from the feature title; compute `spec_dir=./.claude/specs/{feature_name}/`.
-- Artifacts:
-  - `00-repo-scan.md` (unless `--skip-scan`)
-  - `01-product-requirements.md` (PRD, after approval)
-  - `02-system-architecture.md` (Architecture, after approval)
-  - `03-sprint-plan.md` (SM plan, after approval; skipped if `--direct-dev`)
-- Always echo saved paths after writing.
-</global_instructions>
-
-<coding_instructions>
-- Dev phase must execute tasks via bash Codex CLI: `codex e --full-auto --skip-git-repo-check -m gpt-5 "<TASK with brief CONTEXT>"`.
-- QA phase must execute tasks via bash Codex CLI: `codex e --full-auto --skip-git-repo-check -m gpt-5 "<TASK with brief CONTEXT>"`.
-- Treat `-m gpt-5` purely as a model parameter; avoid “agent” wording.
-- Keep Codex prompts concise and include necessary paths and short summaries.
-- Apply the global retry policy (up to 5 attempts); if still failing, stop and report.
-</coding_instructions>
-
-<result_instructions>
-- Provide concise progress updates between phases.
-- Before each approval gate, present: short summary + quality score (if applicable) + clear confirmation question.
-- Gates apply to Phases 1–3 (PO/Architect/SM) only. Proceed only on explicit "yes" (case-insensitive). On "yes": save to the canonical path, echo it, and advance to the next phase.
-- Any non-"yes" reply: do not save and do not proceed; offer refinement, re-ask, or cancellation options.
-- Phase 0 has no gate: save scan summary (unless `--skip-scan`) and continue automatically to Phase 1.
-</result_instructions>
-
-<thinking_instructions>
-- Identify the lowest-confidence or lowest-scoring areas and focus questions there (2–3 at a time max).
-- Make assumptions explicit and request confirmation for high-impact items.
-- Cross-check consistency across PRD, Architecture, and SM plan before moving to Dev.
-</thinking_instructions>
-
-<context>
-- Repository-aware behavior: If not `--skip-scan`, perform a local repository scan first and cache summary as `00-repo-scan.md` for downstream use.
-- Reference internal guidance implicitly (PO/Architect/SM/Dev/QA responsibilities), but avoid copying long texts verbatim. Embed essential behaviors in prompts below.
-</context>
-
-<workflows>
-1) Phase 0 — Repository Scan (optional, default on)
-   - Run locally if not `--skip-scan`.
-   - Task: Analyze project structure, stack, patterns, documentation, workflows using UltraThink.
-   - Output: succinct Markdown summary.
-   - Save and proceed automatically: write `spec_dir/00-repo-scan.md` and then continue to Phase 1 (no confirmation required).
-
-2) Phase 1 — Product Requirements (PO)
-   - Goal: PRD quality ≥ 90 with category breakdown.
-   - Local prompt:
-     - Role: Sarah (BMAD PO) — meticulous, analytical, user-focused.
-     - Include: user request; scan summary/path if available.
-     - Produce: PRD draft (exec summary, business objectives, personas, functional epics/stories+AC, non-functional, constraints, scope & phasing, risks, dependencies, appendix).
-     - Score: 100-point breakdown (Business Value & Goals 30; Functional 25; UX 20; Technical Constraints 15; Scope & Priorities 10) + rationale.
-     - Ask: 2–5 focused clarification questions on lowest-scoring areas.
-     - No saving during drafting.
-   - Loop: Ask user, refine, rescore until ≥ 90.
-   - Gate: Ask confirmation (user language). Only if user replies "yes": save `01-product-requirements.md` and move to Phase 2; otherwise stay here and continue refinement.
-
-3) Phase 2 — System Architecture (Architect)

-     - Include: PRD content; scan summary/path.
-     - Produce: initial architecture (components/boundaries, data flows, security model, deployment, tech choices with justifications, diagrams guidance, implementation guidance).
-     - Score: 100-point breakdown (Design 30; Tech Selection 25; Scalability/Performance 20; Security/Reliability 15; Feasibility 10) + rationale.
-     - Ask: targeted technical questions for critical decisions.
-     - No saving during drafting.
-   - Loop: Ask user, refine, rescore until ≥ 90.
-   - Gate: Ask confirmation (user language). Only if user replies "yes": save `02-system-architecture.md` and move to Phase 3; otherwise stay here and continue refinement.
-
-4) Phase 3 — Sprint Planning (SM; skipped if `--direct-dev`)
-   - Goal: Actionable sprint plan (stories, tasks 4–8h, estimates, dependencies, risks).
-   - Local prompt:
-     - Role: BMAD SM — organized, methodical; dependency mapping; capacity & risk aware.
-     - Include: scan summary/path; PRD path; Architecture path.

-     - No saving during drafting.
-   - Gate: Ask confirmation (user language). Only if user replies "yes": save `03-sprint-plan.md` and move to Phase 4; otherwise stay here and continue refinement.
-
-5) Phase 4 — Development (Dev)
-   - Goal: Implement per PRD/Architecture/SM plan with tests; report progress.
-   - Execute via bash Codex CLI (required):
-     - Command: `codex e --full-auto --skip-git-repo-check -m gpt-5 "Implement per PRD/Architecture/Sprint plan with tests; report progress and blockers. Context: [paths + brief summaries]."`
-     - Include paths: `00-repo-scan.md` (if exists), `01-product-requirements.md`, `02-system-architecture.md`, `03-sprint-plan.md` (if exists).
-     - Follow retry policy (5 attempts); if still failing, stop and report.
-   - Orchestrator remains responsible for approvals and saving as needed.

-# Requirements Clarity Skill
-
-## Description
-
-Automatically transforms vague requirements into actionable PRDs through systematic clarification with a 100-point scoring system.
-
-## Activation
-
-Auto-activate when detecting vague requirements:
-
-1. **Vague Feature Requests**
-   - User says: "add login feature", "implement payment", "create dashboard"
-   - Missing: How, with what technology, what constraints?
-
-2. **Missing Technical Context**
-   - No technology stack mentioned
-   - No integration points identified
-   - No performance/security constraints
-
-3. **Incomplete Specifications**
-   - No acceptance criteria
-   - No success metrics
-   - No edge cases considered
-   - No error handling mentioned
-
-4. **Ambiguous Scope**
-   - Unclear boundaries ("user management" - what exactly?)
-   - No distinction between MVP and future enhancements
-   - Missing "what's NOT included"
-
-**Do NOT activate when**:
-- Specific file paths mentioned (e.g., "auth.go:45")
-- Code snippets included
-- Existing functions/classes referenced
-- Bug fixes with clear reproduction steps
-
-## Core Principles
-
-1. **Systematic Questioning**
-   - Ask focused, specific questions
-   - One category at a time (2-3 questions per round)
-   - Build on previous answers
-   - Avoid overwhelming users
-
-2. **Quality-Driven Iteration**
-   - Continuously assess clarity score (0-100)
-   - Identify gaps systematically
-   - Iterate until ≥ 90 points
-   - Document all clarification rounds
-
-3. **Actionable Output**
-   - Generate concrete specifications
-   - Include measurable acceptance criteria
-   - Provide executable phases
-   - Enable direct implementation
-
-## Clarification Process
-
-### Step 1: Initial Requirement Analysis
-
-**Input**: User's requirement description
-
-**Tasks**:
-1. Parse and understand core requirement
-2. Generate feature name (kebab-case format)
-3. Determine document version (default `1.0` unless user specifies otherwise)
-4. Ensure `./docs/prds/` exists for PRD output
-5. Perform initial clarity assessment (0-100)
-
-**Assessment Rubric**:
-```
-Functional Clarity: /30 points
-- Clear inputs/outputs: 10 pts
-- User interaction defined: 10 pts
-- Success criteria stated: 10 pts
-
-Technical Specificity: /25 points
-- Technology stack mentioned: 8 pts
-- Integration points identified: 8 pts
-- Constraints specified: 9 pts
-
-Implementation Completeness: /25 points
-- Edge cases considered: 8 pts
-- Error handling mentioned: 9 pts
-- Data validation specified: 8 pts
-
-Business Context: /20 points
-- Problem statement clear: 7 pts
-- Target users identified: 7 pts
-- Success metrics defined: 6 pts
-```
-
-**Initial Response Format**:
-```markdown
-I understand your requirement. Let me help you refine this specification.
-
-**Current Clarity Score**: X/100
-
-**Clear Aspects**:
-- [List what's clear]
-
-**Needs Clarification**:
-- [List gaps]
-
-Let me systematically clarify these points...
-```
-
-### Step 2: Gap Analysis
-
-Identify missing information across four dimensions:
-
-**1. Functional Scope**
-- What is the core functionality?
-- What are the boundaries?
-- What is out of scope?
-- What are edge cases?
-
-**2. User Interaction**
-- How do users interact?
-- What are the inputs?
-- What are the outputs?
-- What are success/failure scenarios?
-
-**3. Technical Constraints**
-- Performance requirements?
-- Compatibility requirements?
-- Security considerations?
-- Scalability needs?
-
-**4. Business Value**
-- What problem does this solve?
-- Who are the target users?
-- What are success metrics?
-- What is the priority?
-
-### Step 3: Interactive Clarification
-
-**Question Strategy**:
-1. Start with highest-impact gaps
-2. Ask 2-3 questions per round
-3. Build context progressively
-4. Use user's language
-5. Provide examples when helpful
-
-**Question Format**:
-```markdown
-I need to clarify the following points to complete the requirements document:
-
-1. **[Category]**: [Specific question]?
-   - For example: [Example if helpful]
-
-2. **[Category]**: [Specific question]?
-
-3. **[Category]**: [Specific question]?
-
-Please provide your answers, and I'll continue refining the PRD.
-```
-
-**After Each User Response**:
-1. Update clarity score
-2. Capture new information in the working PRD outline
-3. Identify remaining gaps
-4. If score < 90: Continue with next round of questions
-5. If score ≥ 90: Proceed to PRD generation
-
-**Score Update Format**:
-```markdown
-Thank you for the additional information!
-
-**Clarity Score Update**: X/100 → Y/100
-
-**New Clarified Content**:
-- [Summarize new information]
-
-**Remaining Points to Clarify**:
-- [List remaining gaps if score < 90]
-
-[If score < 90: Continue with next round of questions]
-[If score ≥ 90: "Perfect! I will now generate the complete PRD document..."]
-```
-
-### Step 4: PRD Generation
-
-Once clarity score ≥ 90, generate comprehensive PRD.
-
-**Output File**:
-
-1. **Final PRD**: `./docs/prds/{feature_name}-v{version}-prd.md`
-
-Use the `Write` tool to create or update this file. Derive `{version}` from the document version recorded in the PRD (default `1.0`).
-

+**Simple tasks**:
+```bash
+codeagent-wrapper "simple task" [working_dir]
+codeagent-wrapper --backend gemini "simple task"
+```
+
+## Backends
+
+| Backend | Command | Description |
+|---------|---------|-------------|
+| codex | `--backend codex` | OpenAI Codex (default) |
+| claude | `--backend claude` | Anthropic Claude |
+| gemini | `--backend gemini` | Google Gemini |
+
+## Parameters
+
+- `task` (required): Task description, supports `@file` references
+- `working_dir` (optional): Working directory (default: current)
+- `--backend` (optional): Select AI backend (codex/claude/gemini, default: codex)
+  - **Note**: Claude backend defaults to `--dangerously-skip-permissions` for automation compatibility
+
+## Return Format
+
+```
+Agent response text here...
+
+---
+SESSION_ID: 019a7247-ac9d-71f3-89e2-a823dbd8fd14
+```
+
+## Resume Session
+
+```bash
+# Resume with default backend
+codeagent-wrapper resume <session_id> - <<'EOF'
+<follow-up task>
+EOF
+
+# Resume with specific backend
+codeagent-wrapper --backend claude resume <session_id> - <<'EOF'
+<follow-up task>
+EOF
+```
+
+## Parallel Execution
+
+**With global backend**:
+```bash
+codeagent-wrapper --parallel --backend claude <<'EOF'
+---TASK---
+id: task1
+workdir: /path/to/dir
+---CONTENT---
+task content
+---TASK---
+id: task2
+dependencies: task1
+---CONTENT---
+dependent task
+EOF
+```
+
+**With per-task backend**:
+```bash
+codeagent-wrapper --parallel <<'EOF'
+---TASK---
+id: task1
+backend: codex
+workdir: /path/to/dir
+---CONTENT---
+analyze code structure
+---TASK---
+id: task2
+backend: claude
+dependencies: task1
+---CONTENT---
+design architecture based on analysis
+---TASK---
+id: task3
+backend: gemini
+dependencies: task2
+---CONTENT---
+generate implementation code
+EOF
+```
+
+**Concurrency Control**:
+Set `CODEAGENT_MAX_PARALLEL_WORKERS` to limit concurrent tasks (default: unlimited).
+
+## Environment Variables
+
+- `CODEX_TIMEOUT`: Override timeout in milliseconds (default: 7200000 = 2 hours)
+- `CODEAGENT_SKIP_PERMISSIONS`: Control permission checks
+  - For **Claude** backend: Set to `true`/`1` to **disable** `--dangerously-skip-permissions` (default: enabled)
+  - For **Codex/Gemini** backends: Set to `true`/`1` to enable permission skipping (default: disabled)
+- `CODEAGENT_MAX_PARALLEL_WORKERS`: Limit concurrent tasks in parallel mode (default: unlimited, recommended: 8)
+
+## Invocation Pattern
+
+**Single Task**:
+```
+Bash tool parameters:
+- command: codeagent-wrapper --backend <backend> - [working_dir] <<'EOF'
+  <task content>
+  EOF
+- timeout: 7200000
+- description: <brief description>
+```
+
+**Parallel Tasks**:
+```
+Bash tool parameters:
+- command: codeagent-wrapper --parallel --backend <backend> <<'EOF'
+  ---TASK---
+  id: task_id
+  backend: <backend>  # Optional, overrides global
+  workdir: /path
+  dependencies: dep1, dep2
+  ---CONTENT---
+  task content
+  EOF
+- timeout: 7200000
+- description: <brief description>
+```
+
+## Security Best Practices
+
+- **Claude Backend**: Defaults to `--dangerously-skip-permissions` for automation workflows
+  - To enforce permission checks with Claude: Set `CODEAGENT_SKIP_PERMISSIONS=true`
+- **Codex/Gemini Backends**: Permission checks enabled by default
+- **Concurrency Limits**: Set `CODEAGENT_MAX_PARALLEL_WORKERS` in production to prevent resource exhaustion
+- **Automation Context**: This wrapper is designed for AI-driven automation where permission prompts would block execution
+
+## Recent Updates
+
+- Multi-backend support for all modes (workdir, resume, parallel)
+- Security controls with configurable permission checks
+- Concurrency limits with worker pool and fail-fast cancellation

+name: codex
+description: Execute Codex CLI for code analysis, refactoring, and automated code changes. Use when you need to delegate complex code tasks to Codex AI with file references (@syntax) and structured output.
+---
+
+# Codex CLI Integration
+
+## Overview
+
+Execute Codex CLI commands and parse structured JSON responses. Supports file references via `@` syntax, multiple models, and sandbox controls.
+
+## When to Use
+
+- Complex code analysis requiring deep understanding
+- Large-scale refactoring across multiple files
+- Automated code generation with safety controls
+
+## Fallback Policy
+
+Codex is the **primary execution method** for all code edits and tests. Direct execution is only permitted when:
+
+1. Codex is unavailable (service down, network issues)
+2. Codex fails **twice consecutively** on the same task
+
+When falling back to direct execution:
+- Log `CODEX_FALLBACK` with the reason
+- Retry Codex on the next task (don't permanently switch)
+- Document the fallback in the final summary
+
+## Usage
+
+**Mandatory**: Run every automated invocation through the Bash tool in the foreground with **HEREDOC syntax** to avoid shell quoting issues, keeping the `timeout` parameter fixed at `7200000` milliseconds (do not change it or use any other entry point).
+
+```bash
+codex-wrapper - [working_dir] <<'EOF'
+<task content here>
+EOF
+```
+
+**Why HEREDOC?** Tasks often contain code blocks, nested quotes, shell metacharacters (`$`, `` ` ``, `\`), and multiline text. HEREDOC (Here Document) syntax passes these safely without shell interpretation, eliminating quote-escaping nightmares.
+
+**Foreground only (no background/BashOutput)**: Never set `background: true`, never accept Claude's "Running in the background" mode, and avoid `BashOutput` streaming loops. Keep a single foreground Bash call per Codex task; if work might be long, split it into smaller foreground runs instead of offloading to background execution.
+
+**Simple tasks** (backward compatibility):
+For simple single-line tasks without special characters, you can still use direct quoting:
+```bash
+codex-wrapper "simple task here" [working_dir]
+```
+
+**Resume a session with HEREDOC:**
+```bash
+codex-wrapper resume <session_id> - [working_dir] <<'EOF'
+<task content>
+EOF
+```
+
+**Cross-platform notes:**
+- **Bash/Zsh**: Use `<<'EOF'` (single quotes prevent variable expansion)
+- **PowerShell 5.1+**: Use `@'` and `'@` (here-string syntax)
+  ```powershell
+  codex-wrapper - @'
+  task content
+  '@
+  ```
+
+## Environment Variables
+
+- **CODEX_TIMEOUT**: Override timeout in milliseconds (default: 7200000 = 2 hours)
+  - Example: `export CODEX_TIMEOUT=3600000` for 1 hour
+
+## Timeout Control
+
+- **Built-in**: Binary enforces 2-hour timeout by default
+- **Override**: Set `CODEX_TIMEOUT` environment variable (in milliseconds, e.g., `CODEX_TIMEOUT=3600000` for 1 hour)
+- **Behavior**: On timeout, sends SIGTERM, then SIGKILL after 5s if process doesn't exit
+- **Exit code**: Returns 124 on timeout (consistent with GNU timeout)
+- **Bash tool**: Always set `timeout: 7200000` parameter for double protection
+
+### Parameters
+
+- `task` (required): Task description, supports `@file` references
+- `working_dir` (optional): Working directory (default: current)
+
+### Return Format
+
+Extracts `agent_message` from Codex JSON stream and appends session ID:
+```
+Agent response text here...
+
+---
+SESSION_ID: 019a7247-ac9d-71f3-89e2-a823dbd8fd14
+```
+
+Error format (stderr):
+```
+ERROR: Error message
+```
+
+Return only the final agent message and session ID—do not paste raw `BashOutput` logs or background-task chatter into the conversation.
+
+### Invocation Pattern
+
+All automated executions must use HEREDOC syntax through the Bash tool in the foreground, with `timeout` fixed at `7200000` (non-negotiable):
+
+```
+Bash tool parameters:
+- command: codex-wrapper - [working_dir] <<'EOF'
+  <task content>
+  EOF
+- timeout: 7200000
+- description: <brief description of the task>
+```
+
+Run every call in the foreground—never append `&` to background it—so logs and errors stay visible for timely interruption or diagnosis.
+
+**Important:** Use HEREDOC (`<<'EOF'`) for all but the simplest tasks. This prevents shell interpretation of quotes, variables, and special characters.
+
+### Examples
+
+**Basic code analysis:**
+```bash
+# Recommended: with HEREDOC (handles any special characters)
+codex-wrapper - <<'EOF'
+explain @src/main.ts
+EOF
+# timeout: 7200000
+
+# Alternative: simple direct quoting (if task is simple)
+codex-wrapper "explain @src/main.ts"
+```
+
+**Refactoring with multiline instructions:**
+```bash
+codex-wrapper - <<'EOF'
+refactor @src/utils for performance:
+- Extract duplicate code into helpers
+- Use memoization for expensive calculations
+- Add inline comments for non-obvious logic
+EOF
+# timeout: 7200000
+```
+
+**Multi-file analysis:**
+```bash
+codex-wrapper - "/path/to/project" <<'EOF'
+analyze @. and find security issues:
+1. Check for SQL injection vulnerabilities
+2. Identify XSS risks in templates
+3. Review authentication/authorization logic
+4. Flag hardcoded credentials or secrets
+EOF
+# timeout: 7200000
+```
+
+**Resume previous session:**
+```bash
+# First session
+codex-wrapper - <<'EOF'
+add comments to @utils.js explaining the caching logic
+EOF
+# Output includes: SESSION_ID: 019a7247-ac9d-71f3-89e2-a823dbd8fd14
+
+# Continue the conversation with more context
+codex-wrapper resume 019a7247-ac9d-71f3-89e2-a823dbd8fd14 - <<'EOF'
+now add TypeScript type hints and handle edge cases where cache is null
+EOF
+# timeout: 7200000
+```
+
+**Task with code snippets and special characters:**
+```bash
+codex-wrapper - <<'EOF'
+Fix the bug in @app.js where the regex /\d+/ doesn't match "123"
+The current code is:
+  const re = /\d+/;
+  if (re.test(input)) { ... }
+Add proper escaping and handle $variables correctly.
+EOF
+```
+
+### Parallel Execution
+
+> Important:
+> - `--parallel` only reads task definitions from stdin.
+> - It does not accept extra command-line arguments (no inline `workdir`, `task`, or other params).
+> - Put all task metadata and content in stdin; nothing belongs after `--parallel` on the command line.
+
+**Correct vs Incorrect Usage**
+
+**Correct:**
+```bash
+# Option 1: file redirection
+codex-wrapper --parallel < tasks.txt
+
+# Option 2: heredoc (recommended for multiple tasks)
+codex-wrapper --parallel <<'EOF'
+---TASK---
+id: task1
+workdir: /path/to/dir
+---CONTENT---
+task content
+EOF
+
+# Option 3: pipe
+echo "---TASK---..." | codex-wrapper --parallel
+```
+
+**Incorrect (will trigger shell parsing errors):**
+```bash
+# Bad: no extra args allowed after --parallel
+codex-wrapper --parallel - /path/to/dir <<'EOF'
+...
+EOF
+
+# Bad: --parallel does not take a task argument
+codex-wrapper --parallel "task description"
+
+# Bad: workdir must live inside the task config
+codex-wrapper --parallel /path/to/dir < tasks.txt
+```
+
+For multiple independent or dependent tasks, use `--parallel` mode with delimiter format:
+
+**Typical Workflow (analyze → implement → test, chained in a single parallel call)**:
+```bash
+codex-wrapper --parallel <<'EOF'
+---TASK---
+id: analyze_1732876800
+workdir: /home/user/project
+---CONTENT---
+analyze @spec.md and summarize API and UI requirements
+---TASK---
+id: implement_1732876801
+workdir: /home/user/project
+dependencies: analyze_1732876800
+---CONTENT---
+implement features from analyze_1732876800 summary in backend @services and frontend @ui
+---TASK---
+id: test_1732876802
+workdir: /home/user/project
+dependencies: implement_1732876801
+---CONTENT---
+add and run regression tests covering the new endpoints and UI flows
+EOF
+```
+A single `codex-wrapper --parallel` call schedules all three stages concurrently, using `dependencies` to enforce sequential ordering without multiple invocations.
+
+```bash
+codex-wrapper --parallel <<'EOF'
+---TASK---
+id: backend_1732876800
+workdir: /home/user/project/backend
+---CONTENT---
+implement /api/orders endpoints with validation and pagination
+---TASK---
+id: frontend_1732876801
+workdir: /home/user/project/frontend
+---CONTENT---
+build Orders page consuming /api/orders with loading/error states
+---TASK---
+id: tests_1732876802
+workdir: /home/user/project/tests
+dependencies: backend_1732876800, frontend_1732876801
+---CONTENT---
+run API contract tests and UI smoke tests (waits for backend+frontend)
+EOF
+```
+
+**Delimiter Format**:
+- `---TASK---`: Starts a new task block
+- `id: <task-id>`: Required, unique task identifier
+  - Best practice: use `<feature>_<timestamp>` format (e.g., `auth_1732876800`, `api_test_1732876801`)
+  - Ensures uniqueness across runs and makes tasks traceable
+- `workdir: <path>`: Optional, working directory (default: `.`)
+  - Best practice: use absolute paths (e.g., `/home/user/project/backend`)
+  - Avoids ambiguity and ensures consistent behavior across environments
+  - Must be specified inside each task block; do not pass `workdir` as a CLI argument to `--parallel`
+  - Each task can set its own `workdir` when different directories are needed
+- `dependencies: <id1>, <id2>`: Optional, comma-separated task IDs
+- `session_id: <uuid>`: Optional, resume a previous session
+- `---CONTENT---`: Separates metadata from task content
+- Task content: Any text, code, special characters (no escaping needed)
+
+**Dependencies Best Practices**
+
+- Avoid multiple invocations: Place "analyze then implement" in a single `codex-wrapper --parallel` call, chaining them via `dependencies`, rather than running analysis first and then launching implementation separately.
+- Naming convention: Use `<action>_<timestamp>` format (e.g., `analyze_1732876800`, `implement_1732876801`), where action names map to features/stages and timestamps ensure uniqueness and sortability.
+- Dependency chain design: Keep chains short; only add dependencies for tasks that truly require ordering, let others run in parallel, avoiding over-serialization that reduces throughput.
+
+**Resume Failed Tasks**:
+```bash
+# Use session_id from previous output to resume
+codex-wrapper --parallel <<'EOF'
+---TASK---
+id: T2
+session_id: 019xxx-previous-session-id
+---CONTENT---
+fix the previous error and retry
+EOF
+```
+
+**Output**: Human-readable text format
+```
+=== Parallel Execution Summary ===
+Total: 3 | Success: 2 | Failed: 1
+
+--- Task: T1 ---
+Status: SUCCESS
+Session: 019xxx
+
+Task output message...
+
+--- Task: T2 ---
+Status: FAILED (exit code 1)
+Error: some error message
+```
+
+**Features**:
+- Automatic topological sorting based on dependencies
+- Unlimited concurrency for independent tasks
+- Error isolation (failed tasks don't stop others)
+- Dependency blocking (dependent tasks skip if parent fails)
+
+## Notes
+
+- **Binary distribution**: Single Go binary, zero dependencies
+- **Installation**: Download from GitHub Releases or use install.sh
+- **Cross-platform compatible**: Linux (amd64/arm64), macOS (amd64/arm64)
+- All automated runs must use the Bash tool with the fixed timeout to provide dual timeout protection and unified logging/exit semantics
+for automation (new sessions only)
+- Uses `--skip-git-repo-check` to work in any directory
+- Streams progress, returns only final agent message
+- Every execution returns a session ID for resuming conversations
+- Requires Codex CLI installed and authenticated

+description: Execute Gemini CLI for AI-powered code analysis and generation. Use when you need to leverage Google's Gemini models for complex reasoning tasks.
+---
+
+# Gemini CLI Integration
+
+## Overview
+
+Execute Gemini CLI commands with support for multiple models and flexible prompt input. Integrates Google's Gemini AI models into Claude Code workflows.
+
+## When to Use
+
+- Complex reasoning tasks requiring advanced AI capabilities
+- Code generation and analysis with Gemini models
+- Tasks requiring Google's latest AI technology
+- Alternative perspective on code problems
+
+## Usage
+**Mandatory**: Run via uv with fixed timeout 7200000ms (foreground):
+```bash
+uv run ~/.claude/skills/gemini/scripts/gemini.py "<prompt>" [working_dir]
+```
+
+**Optional** (direct execution or using Python):
+```bash
+~/.claude/skills/gemini/scripts/gemini.py "<prompt>" [working_dir]
+# or
+python3 ~/.claude/skills/gemini/scripts/gemini.py "<prompt>" [working_dir]
+```
+
+## Environment Variables
+
+- **GEMINI_MODEL**: Configure model (default: `gemini-3-pro-preview`)
+  - Example: `export GEMINI_MODEL=gemini-3`
+
+## Timeout Control
+
+- **Fixed**: 7200000 milliseconds (2 hours), immutable
+- **Bash tool**: Always set `timeout: 7200000` for double protection
+
+### Parameters
+
+- `prompt` (required): Task prompt or question
+- `working_dir` (optional): Working directory (default: current directory)
+
+### Return Format
+
+Plain text output from Gemini:
+
+```text
+Model response text here...
+```
+
+Error format (stderr):
+
+```text
+ERROR: Error message
+```
+
+### Invocation Pattern
+
+When calling via Bash tool, always include the timeout parameter:
+
+```yaml
+Bash tool parameters:
+- command: uv run ~/.claude/skills/gemini/scripts/gemini.py "<prompt>"
+- timeout: 7200000
+- description: <brief description of the task>
+```
+
+Alternatives:
+
+```yaml
+# Direct execution (simplest)
+- command: ~/.claude/skills/gemini/scripts/gemini.py "<prompt>"
+
+# Using python3
+- command: python3 ~/.claude/skills/gemini/scripts/gemini.py "<prompt>"
+```
+
+### Examples
+
+**Basic query:**
+
+```bash
+uv run ~/.claude/skills/gemini/scripts/gemini.py "explain quantum computing"
+# timeout: 7200000
+```
+
+**Code analysis:**
+
+```bash
+uv run ~/.claude/skills/gemini/scripts/gemini.py "review this code for security issues: $(cat app.py)"
+# timeout: 7200000
+```
+
+**With specific working directory:**
+
+```bash
+uv run ~/.claude/skills/gemini/scripts/gemini.py "analyze project structure" "/path/to/project"
+# timeout: 7200000
+```
+
+**Using python3 directly (alternative):**
+
+```bash
+python3 ~/.claude/skills/gemini/scripts/gemini.py "your prompt here"
+```
+
+## Notes
+
+- **Recommended**: Use `uv run` for automatic Python environment management (requires uv installed)
+- **Alternative**: Direct execution `./gemini.py` (uses system Python via shebang)
+- Python implementation using standard library (zero dependencies)
+- Cross-platform compatible (Windows/macOS/Linux)
+- PEP 723 compliant (inline script metadata)
+- Requires Gemini CLI installed and authenticated
+- Supports all Gemini model variants (configure via `GEMINI_MODEL` environment variable)
+- Output is streamed directly from Gemini CLI

+
+# Product Requirements Skill
+
+## Overview
+
+Transform user requirements into professional Product Requirements Documents (PRDs) through interactive dialogue, quality scoring, and iterative refinement. Act as Sarah, a meticulous Product Owner who ensures requirements are clear, testable, and actionable before documentation.
+
+## Core Identity
+
+- **Role**: Technical Product Owner & Requirements Specialist
+- **Approach**: Systematic, quality-driven, user-focused
+- **Method**: Quality scoring (100-point scale) with 90+ threshold for PRD generation
+- **Output**: Professional yet concise PRDs saved to `docs/{feature-name}-prd.md`
+
+## Interactive Process
+
+### Step 1: Initial Understanding & Context Gathering
+
+Greet as Sarah and immediately gather project context:
+
+```
+"Hi! I'm Sarah, your Product Owner. I'll help define clear requirements for your feature.
+
+Let me first understand your project context..."
+```
+
+**Context gathering actions:**
+1. Read project README, package.json/pyproject.toml in parallel
+2. Understand tech stack, existing architecture, and conventions
+3. Present initial interpretation of the user's request within project context
+4. Ask: "Is this understanding correct? What would you like to add?"
+
+**Early stop**: Once you can articulate the feature request clearly within the project's context, proceed to quality assessment.
+
+### Step 2: Quality Assessment (100-Point System)
+
+Evaluate requirements across five dimensions:
+
+#### Scoring Breakdown:
+
+**Business Value & Goals (30 points)**
+- 10 pts: Clear problem statement and business need
+- 10 pts: Measurable success metrics and KPIs
+- 10 pts: Expected outcomes and ROI justification
+
+**Functional Requirements (25 points)**
+- 10 pts: Complete user stories with acceptance criteria
+- 10 pts: Clear feature descriptions and workflows
+- 5 pts: Edge cases and error handling defined
+
+**User Experience (20 points)**
+- 8 pts: Well-defined user personas
+- 7 pts: User journey and interaction flows
+- 5 pts: UI/UX preferences and constraints
+
+**Technical Constraints (15 points)**
+- 5 pts: Performance requirements
+- 5 pts: Security and compliance needs
+- 5 pts: Integration requirements
+
+**Scope & Priorities (10 points)**
+- 5 pts: Clear MVP definition
+- 3 pts: Phased delivery plan
+- 2 pts: Priority rankings
+
+**Display format:**
+```
+📊 Requirements Quality Score: [TOTAL]/100
+
+Breakdown:
+- Business Value & Goals: [X]/30
+- Functional Requirements: [X]/25
+- User Experience: [X]/20
+- Technical Constraints: [X]/15
+- Scope & Priorities: [X]/10
+
+[If < 90]: Let me ask targeted questions to improve clarity...
+[If ≥ 90]: Excellent! Ready to generate PRD.
+```
+
+### Step 3: Targeted Clarification
+
+**If score < 90**, use `AskUserQuestion` tool to clarify gaps. Focus on the lowest-scoring area first.
+
+**Question categories by dimension:**
+
+**Business Value (if <24/30):**
+- "What specific business problem are we solving?"
+- "How will we measure success?"
+- "What happens if we don't build this?"
+
+**Functional Requirements (if <20/25):**
+- "Can you walk me through the main user workflows?"
+- "What should happen when [specific edge case]?"
+- "What are the must-have vs. nice-to-have features?"
+
+**User Experience (if <16/20):**
+- "Who are the primary users?"
+- "What are their goals and pain points?"
+- "Can you describe the ideal user experience?"
+
+**Technical Constraints (if <12/15):**
+- "What performance expectations do you have?"
+- "Are there security or compliance requirements?"
+- "What systems need to integrate with this?"
+
+**Scope & Priorities (if <8/10):**
+- "What's the minimum viable product (MVP)?"
+- "How should we phase the delivery?"
+- "What are the top 3 priorities?"
+
+**Ask 2-3 questions at a time** using `AskUserQuestion` tool. Don't overwhelm.
+
+### Step 4: Iterative Refinement
+
+After each user response:
+1. Update understanding
+2. Recalculate quality score
+3. Show progress: "Great! That improved [area] from X to Y."
+4. Continue until 90+ threshold met
+
+### Step 5: Final Confirmation & PRD Generation
+
+When score ≥ 90:
+
+```
+"Excellent! Here's the final PRD summary:
+
+[2-3 sentence executive summary]
+
+📊 Final Quality Score: [SCORE]/100
+
+Generating professional PRD at docs/{feature-name}-prd.md..."
+```
+
+Generate PRD using template below, then confirm:
+```
+"✅ PRD saved to docs/{feature-name}-prd.md
+
+Review the document and let me know if any adjustments are needed."
+```
+
+## PRD Template (Streamlined Professional Version)

+name: prototype-prompt-generator
+description: This skill should be used when users need to generate detailed, structured prompts for creating UI/UX prototypes. Trigger when users request help with "create a prototype prompt", "design a mobile app", "generate UI specifications", or need comprehensive design documentation for web/mobile applications. Works with multiple design systems including WeChat Work, iOS Native, Material Design, and Ant Design Mobile.
+---
+
+# Prototype Prompt Generator
+
+## Overview
+
+Generate comprehensive, production-ready prompts for UI/UX prototype creation. Transform user requirements into detailed technical specifications that include design systems, color palettes, component specifications, layout structures, and implementation guidelines. Output prompts are structured for optimal consumption by AI tools or human developers building HTML/CSS/React prototypes.
+
+## Workflow
+
+### Step 1: Gather Requirements
+
+Begin by collecting essential information from the user. Ask targeted questions to understand:
+
+**Application Type & Purpose:**
+- What kind of application? (e.g., enterprise tool, e-commerce, social media, dashboard)
+- Who are the target users?
+- What are the primary use cases and workflows?
+
+**Platform & Context:**
+- Target platform: iOS, Android, Web, WeChat Mini Program, or cross-platform?
+- Device: Mobile phone, tablet, desktop, or responsive?
+- Viewport dimensions if known (e.g., 375px for iPhone, 1200px for desktop)
+
+**Design Preferences:**
+- Design style: WeChat Work, iOS Native, Material Design, Ant Design Mobile, or custom?
+- Brand colors or visual preferences?
+- Any design references or inspiration?
+
+**Feature Requirements:**
+- Key pages and features needed
+- Navigation structure (tabs, drawer, stack navigation)
+- Data to display (metrics, lists, forms, media)
+- User interactions (tap, swipe, long-press, etc.)
+
+**Content & Data:**
+- Actual content to display (realistic text, numbers, names)
+- Empty states, error states, loading states
+- Any specific business logic or rules
+
+**Technical Constraints:**
+- Framework preference: Plain HTML, React, Vue, or framework-agnostic?
+- CSS approach: Tailwind CSS, CSS Modules, styled-components?
+- Image assets: Real images, placeholders, or specific sources?
+- CDN dependencies or version requirements?
+
+**Ask questions incrementally** (2-3 at a time) to avoid overwhelming the user. Many details can be inferred from context or filled with sensible defaults.
+
+### Step 2: Select Design System
+
+Based on the gathered requirements, choose the appropriate design system from `references/design-systems.md`:
+
+**WeChat Work Style:**
+- **When to use**: Chinese enterprise applications, work management tools, B2B platforms, internal business systems
+- **Characteristics**: Simple and professional, tech blue primary color, clear information hierarchy
+- **Key audience**: Chinese business users, corporate environments
+
+**iOS Native Style:**
+- **When to use**: iOS-specific apps, Apple ecosystem integration, apps targeting iPhone/iPad users
+- **Characteristics**: Minimalist, spacious layouts, San Francisco font, system colors
+- **Key audience**: Apple users, consumer apps, content-focused applications
+
+**Material Design Style:**
+- **When to use**: Android-first apps, Google ecosystem integration, cross-platform with Material UI
+- **Characteristics**: Bold graphics, elevation system, ripple effects, Roboto font
+- **Key audience**: Android users, Google services, developer tools
+
+**Ant Design Mobile Style:**
+- **When to use**: Enterprise mobile applications with complex data entry and forms
+- **Characteristics**: Efficiency-oriented, consistent components, suitable for business applications
+- **Key audience**: Business users, enterprise mobile apps, data-heavy interfaces
+
+**If the user hasn't specified a design system**, recommend one based on:
+- Geographic location: Chinese users → WeChat Work, Western users → iOS/Material
+- Platform: iOS → iOS Native, Android → Material Design
+- Application type: Enterprise B2B → WeChat Work or Ant Design, Consumer app → iOS or Material
+
+Load the complete design system specifications from `references/design-systems.md` to ensure accurate color codes, component dimensions, and interaction patterns.
+
+### Step 3: Structure the Prompt
+
+Using the template from `references/prompt-structure.md`, construct a comprehensive prompt with these sections:
+
+**1. Role Definition**
+Define expertise relevant to the prototype:
+```
+# Role
+You are a world-class UI/UX engineer and frontend developer, specializing in [specific domain] using [technologies].
+```
+
+**2. Task Description**
+State clearly what to build and the design style:
+```
+# Task
+Create a [type] prototype for [application description].
+Design style must strictly follow [design system], with core keywords: [3-5 key attributes].
+```
+
+**3. Tech Stack Specifications**
+List all technologies, frameworks, and resources:
+- File structure (single HTML, multi-page, component-based)
+- Framework and version (e.g., Tailwind CSS CDN)
+- Device simulation (viewport size, device chrome)

+
+**(a) Color Palette:**
+Include all colors with hex codes:
+- Background colors (main, section, card)
+- Primary and accent colors with usage
+- Status colors (success, warning, error)
+- Text colors (title, body, secondary, disabled)
+- UI element colors (borders, dividers)
+
+**(b) UI Style Characteristics:**
+Specify for each component type:
+- Cards: background, radius, shadow, border, padding
+- Buttons: variants (primary, secondary, ghost), dimensions, states
+- Icons: style, sizes, colors, containers
+- List items: layout, height, divider style, active state
+- Shadows: type and usage
+
+**(c) Layout Structure:**
+Describe each major section:
+- Top navigation bar: height, title style, icons, background
+- Content areas: grids, cards, lists, spacing
+- Quick access areas: icon grids, layouts
+- Data display cards: metrics, layout, styling
+- Feature lists: structure, icons, interactions

+- Fixed/sticky positioning for navigation
+- Spacing scale (margins, padding, gaps)
+- Typography (font family, sizes, weights)
+- Interactive states (hover, active, focus, disabled)
+- Icon sources and usage
+- Border and divider styling
+
+**6. Tailwind Configuration**
+If using Tailwind CSS, provide custom config:
+```javascript
+tailwind.config = {
+  theme: {
+    extend: {
+      colors: {
+        'brand-primary': '#3478F6',
+        // ... all custom colors
+      }
+    }
+  }
+}
+```
+
+**7. Content Structure & Hierarchy**
+Visualize the page structure as a tree:
+```
+Page Name
+├─ Section 1
+│  ├─ Element 1
+│  └─ Element 2
+├─ Section 2
+│  ├─ Subsection A
+│  │  ├─ Item 1
+│  │  └─ Item 2
+│  └─ Subsection B
+└─ Section 3
+```
+
+**8. Special Requirements**
+Highlight unique considerations:
+- Design system-specific guidelines
+- Primary color application scenarios
+- Interaction details (tap feedback, animations, gestures)
+- Accessibility requirements (contrast, touch targets, ARIA)
+- Performance considerations (image optimization, lazy loading)
+
+**9. Output Format**
+Specify the exact deliverable:
+```
+# Output Format
+
+Please output complete [file type] code, ensuring:
+1. [Requirement 1]
+2. [Requirement 2]
+...
+
+The output should be production-ready and viewable at [viewport] on [device].
+```
+
+### Step 4: Populate with Specifics
+
+Replace all template placeholders with concrete values:
+
+**Replace vague terms with precise specifications:**
+- ❌ "Use blue colors" → ✅ "Primary: #3478F6 (tech blue), Link: #576B95 (link blue)"
+- ❌ "Make buttons rounded" → ✅ "Border radius: 4px (Tailwind: rounded)"
+- ❌ "Add some spacing" → ✅ "Card spacing: 12px, page margins: 16px"
+- ❌ "Display user info" → ✅ "Show username (15px bold), email (13px gray), avatar (48px circle)"
+
+**Use real content, not placeholders:**
+- ❌ "Lorem ipsum dolor sit amet" → ✅ "Customer Total: 14, Today's New Customers: 1, Today's Revenue: ¥0.00"
+- ❌ "[Company Name]" → ✅ "Acme Insurance Co."
+- ❌ "Feature 1, Feature 2, Feature 3" → ✅ "Customer Contact, Customer Moments, Customer Groups"
+
+**Specify all measurements:**
+- Component heights (44px, 50px, 64px)
+- Font sizes (13px, 15px, 16px, 18px)
+- Spacing values (8px, 12px, 16px, 24px)
+- Icon sizes (24px, 32px, 48px)
+- Border radius (4px, 8px, 10px)
+
+**Define all states:**
+- Normal: base colors and styles
+- Hover: if applicable (desktop)
+- Active/Pressed: opacity or background changes
+- Disabled: grayed out with reduced opacity
+- Selected: highlight color (often primary brand color)
+
+**Include all colors:**
+Every color mentioned must have a hex code. Reference the chosen design system from `references/design-systems.md` for accurate values.
+
+### Step 5: Quality Assurance
+
+Before presenting the final prompt, verify against the checklist in `references/prompt-structure.md`:
+
+**Completeness Check:**
+- [ ] Role clearly defined with relevant expertise
+- [ ] Task explicitly states what to build and design style
+- [ ] All tech stack components listed with versions/CDNs
+- [ ] Complete color palette with hex codes for all colors
+- [ ] All UI components specified with exact dimensions and styles
+- [ ] Page layout fully described with precise measurements
+- [ ] Actual, realistic content provided (no placeholders like "Lorem Ipsum" or "[Name]")
+- [ ] Implementation details cover all technical requirements
+- [ ] Tailwind config included if using Tailwind CSS
+- [ ] Content hierarchy visualized as a tree structure
+- [ ] Special requirements and interactions documented
+- [ ] Output format clearly defined with all deliverables
+
+**Clarity Check:**
+- [ ] No ambiguous terms or vague descriptions (e.g., "some padding", "nice colors")
+- [ ] All measurements specified with units (px, rem, %, vh, etc.)
+- [ ] All colors defined with hex codes (e.g., #3478F6, not just "blue")
+- [ ] Component states described (normal, hover, active, disabled, selected)
+- [ ] Layout relationships clear (parent-child, spacing, alignment, z-index)
+
+**Specificity Check:**
+- [ ] Design system explicitly named (WeChat Work, iOS Native, Material Design, etc.)
+- [ ] Viewport dimensions provided (e.g., 375px × 812px for iPhone)
+- [ ] Typography scale defined (sizes, weights, line heights)
+- [ ] Interactive behaviors documented with timing if animated
+- [ ] Edge cases considered (long text overflow, empty states, loading, errors)
+
+**Realism Check:**
+- [ ] Real content examples, not Latin placeholder text
+- [ ] Authentic data points (realistic numbers, names, dates, amounts)
+- [ ] Practical feature set (not overengineered or underspecified)
+- [ ] Appropriate complexity for the stated use case
+
+**Technical Accuracy Check:**
+- [ ] Valid Tailwind class names (if using Tailwind)
+- [ ] Correct CDN links with versions (e.g., https://cdn.tailwindcss.com)
+- [ ] Proper HTML structure implied (semantic elements, hierarchy)
+- [ ] Feasible layout techniques (Flexbox/Grid patterns that work)
+- [ ] Accessible markup considerations (touch targets ≥44px, color contrast)
+
+If any checks fail, refine the prompt before proceeding.
+
+### Step 6: Present and Iterate
+
+**Present the generated prompt to the user** with a brief explanation:
+- What design system was selected and why
+- Key design decisions made
+- Any assumptions or defaults applied
+- How to use the prompt (copy and provide to another AI tool or developer)
+
+**Offer refinement options:**
+- "Would you like to adjust any colors or spacing?"
+- "Should we add more pages or features?"
+- "Do you want to change the design system?"
+- "Any specific interactions or animations to emphasize?"
+
+**Iterate based on feedback:**
+If the user requests changes:
+1. Update the relevant sections of the prompt
+2. Maintain consistency across all sections
+3. Re-verify against the quality checklist
+4. Present the updated prompt
+
+**Save or Export:**
+Offer to save the prompt to a file:
+- Markdown file for documentation
+- Text file for easy copying
+- Include as a code block for immediate use
+
+## Best Practices
+
+**1. Default to High Quality:**
+Even if the user provides minimal requirements, generate a comprehensive prompt. It's easier to remove details than to add them later. Include:
+- Complete color palettes (8-12 colors minimum)
+- All common UI components (buttons, cards, lists, inputs)
+- Multiple component states (normal, active, disabled)
+- Responsive considerations
+- Accessibility basics (contrast, touch targets)
+
+**2. Use Design System Defaults Intelligently:**
+When user requirements are vague:
+- Apply the full design system consistently
+- Use standard component dimensions from the design system
+- Follow established patterns (e.g., WeChat Work's 64px list items)
+- Include typical interaction patterns for the platform
+
+**3. Prioritize Clarity Over Brevity:**
+Longer, detailed prompts produce better prototypes than short, vague ones. Include:
+- Exact hex codes instead of color names
+- Precise measurements instead of relative terms
+- Specific component layouts instead of general descriptions
+- Actual content instead of placeholder text
+
+**4. Think Mobile-First:**
+For mobile applications, always consider:
+- Safe areas (iOS notch, Android gesture bar)
+- Touch target sizes (minimum 44px × 44px)
+- Thumb-reachable zones (bottom navigation over top)
+- Portrait orientation primarily (landscape as secondary)
+- One-handed operation where possible
+
+**5. Balance Flexibility and Specificity:**
+- Be specific about core design elements (colors, typography, key components)
+- Allow flexibility in implementation details (exact animation timing, minor spacing adjustments)
+- Specify "must-haves" clearly, mark "nice-to-haves" as optional
+
+**6. Consider the Full User Journey:**
+Include specifications for:
+- Entry points (splash screen, onboarding if applicable)
+- Primary workflows (happy path through key features)
+- Edge cases (empty states, error states, loading states)
+- Exit points (logout, back navigation, completion states)
+
+**7. Provide Context, Not Just Specs:**
+Explain the "why" behind design decisions:
+- "Tech blue (#3478F6) for trust and professionalism in enterprise context"
+- "64px list item height for comfortable thumb tapping on mobile"
+- "Fixed bottom tab bar for quick access to primary features"
+
+**8. Validate Technical Feasibility:**
+Before finalizing the prompt:
+- Ensure CSS/Tailwind classes can achieve the described design
+- Verify that layout patterns work with the stated grid/flexbox approach
+- Confirm that the specified viewport can accommodate all content
+- Check that CDN links and versions are correct and available
+
+**9. Make It Actionable:**
+The prompt should enable immediate implementation:
+- Include all necessary CDN links and imports
+- Provide complete Tailwind config (no "...add more as needed")
+- Specify file structure and organization
+- Define clear deliverables (HTML file, React components, etc.)
+
+**10. Anticipate Questions:**
+Address common uncertainties in the prompt:
+- Font fallbacks (e.g., "sans-serif" system font stack)
+- Image dimensions and aspect ratios
+- Icon usage (when to use FontAwesome vs SVG vs emoji)
+- Z-index layering (what's on top)
+- Overflow behavior (scroll, truncate, wrap)
+

+
+## Troubleshooting
+
+**Issue: User requirements are too vague**
+**Solution:** Ask focused questions, provide examples of similar apps, suggest design systems to choose from, or create a default prompt and offer iteration.
+
+**Issue: User wants multiple design styles mixed**
+**Solution:** Pick a primary design system for overall structure and consistency, then incorporate specific elements from other systems as accent features. Explain trade-offs.
+
+**Issue: User specifies impossible or conflicting requirements**
+**Solution:** Identify the conflict, explain why it's problematic (e.g., "64px icons won't fit in a 44px navigation bar"), suggest alternatives, and seek clarification.
+
+**Issue: Too many features for one prompt**
+**Solution:** Focus on the primary page/workflow first, generate that prompt, then create separate prompts for additional features. Maintain consistency across prompts.
+
+**Issue: User lacks technical knowledge**
+**Solution:** Avoid jargon, explain design decisions in plain language, provide visual descriptions instead of technical terms, and include helpful comments in the prompt.
+
+**Issue: Prototype prompt doesn't produce good results**
+**Solution:** Review against the quality checklist, ensure all colors have hex codes, verify all measurements are specified, add more specific content examples, check for ambiguous language.

+## Prompt Generation Workflow
+
+When generating a prototype prompt, follow this workflow:
+
+### Step 1: Gather Requirements
+Ask the user:
+- What type of application? (e.g., enterprise tool, e-commerce, social media)
+- Target platform? (iOS, Android, Web, WeChat Mini Program)
+- Design style preference? (WeChat Work, iOS Native, Material Design, custom)
+- Key features and pages needed?
+- Target users and use cases?
+- Any specific content or data to display?
+- Brand colors or visual preferences?
+
+### Step 2: Select Design System
+Based on requirements, choose the appropriate design system from references/design-systems.md:
+- **WeChat Work**: Chinese enterprise apps, B2B tools
+- **iOS Native**: iOS apps, Apple ecosystem
+- **Material Design**: Android apps, Google ecosystem
+- **Ant Design Mobile**: Enterprise mobile apps with complex forms
+
+### Step 3: Structure the Prompt
+Using the sections above:
+1. Define the role (UI/UX engineer with specific expertise)
+2. Describe the task (what to build, design style, key attributes)
+3. Specify tech stack (frameworks, device, assets, CDNs)
+4. Detail visual design (colors, components, layout, content)
+5. Provide implementation guidelines (technical details)
+6. Include Tailwind config (if using Tailwind)
+7. Show content hierarchy (visual tree structure)
+8. Add special requirements (design system specifics, interactions)
+9. Specify output format (deliverable expectations)
+
+### Step 4: Populate with Specifics
+- Replace all template placeholders with actual values
+- Include real content (text, numbers, labels)
+- Specify exact colors (hex codes)
+- Define precise measurements (px, rem, etc.)
+- List all page elements and features
+- Add interaction states and behaviors
+
+### Step 5: Review and Refine
+Ensure the prompt:
+- Is complete and self-contained
+- Has no ambiguous placeholders
+- Includes all necessary technical details
+- Specifies exact design requirements
+- Provides realistic content examples
+- Defines clear deliverables
+

+## Example Variations
+
+### Minimal Prompt (for simple landing page)
+```
+# Role
+You are a frontend developer specializing in clean, modern web design.
+
+# Task
+Create a single-page landing page (HTML + Tailwind CSS) for a SaaS product.
+Style: Modern, minimal, professional with soft colors.
+
+# Tech Stack
+- Single index.html file
+- Tailwind CSS (CDN)
+- Desktop-first responsive (max 1200px)
+- Use Unsplash for hero image
+
+# Visual Design
+- Colors: Primary #6366F1 (indigo), Background #F9FAFB (gray-50), Text #111827 (gray-900)
+- Sections: Hero (full viewport height) + Features (3 columns) + CTA
+- Typography: System sans-serif, Hero 48px bold, Body 18px regular
+
+# Output Format
+Single HTML file, production-ready, mobile-responsive.
+```
+
+### Complex Prompt (for multi-page app)
+[Follow full template structure with all sections, detailed component specs, multiple pages, complex interactions]
+
+---
+
+## Tips for Effective Prompts
+
+1. **Be Specific**: "Blue button" → "Primary button: #3478F6 background, white text, 44px height, 4px rounded corners"
+
+2. **Provide Context**: Don't just list features, explain their purpose and how they relate to user workflows
+
+3. **Use Real Content**: "Insurance agent dashboard" with "14 customers, ¥1,234.56 revenue" is better than "Dashboard with metrics"
+
+4. **Reference Standards**: "Follow WeChat Work design guidelines" gives Claude a comprehensive style framework
+
+5. **Include Edge Cases**: Mention empty states, loading states, error states, long text handling
+
+6. **Specify Interactions**: Don't assume—explicitly state tap feedback, hover effects, animation timing
+
+7. **Think Mobile-First**: For mobile apps, always specify touch target sizes (minimum 44px), safe areas, gesture support
+
+8. **Consider Accessibility**: Mention color contrast, touch target sizes, semantic HTML, ARIA labels
+
+9. **Balance Detail and Brevity**: Be thorough but organized—use sections and hierarchy to keep prompts scannable
+
+10. **Test Your Mental Model**: Can someone else understand exactly what to build from this prompt? If not, add clarity.
