fix: support model parameter for all backends, auto-inject from settings (#105)

- Add Model field to Config and TaskSpec for per-task model selection
- Parse --model flag and model: metadata in parallel tasks
- Auto-inject model from ~/.claude/settings.json for claude backend in new mode
- Pass --model to claude CLI, -m to gemini CLI, --model to codex CLI
- Preserve --setting-sources "" isolation while reading minimal safe subset
- Add comprehensive tests for model parsing, propagation, and settings injection

Fixes #105

-## Documentation
+## FAQ (Frequently Asked Questions)
 
-### Core Guides
+### Q1: `codeagent-wrapper` execution fails with "Unknown event format"
+
+**Problem:**
+```
+Unknown event format: {"type":"turn.started"}
+Unknown event format: {"type":"assistant", ...}
+```
+
+**Solution:**
+This is a logging event format display issue and does not affect actual functionality. It will be fixed in the next version. You can ignore these log outputs.
+
+**Related Issue:** [#96](https://github.com/cexll/myclaude/issues/96)
+
+---
+
+### Q2: Gemini cannot read files ignored by `.gitignore`
+
+**Problem:**
+When using `codeagent-wrapper --backend gemini`, files in directories like `.claude/` that are ignored by `.gitignore` cannot be read.
+
+**Solution:**
+- **Option 1:** Remove `.claude/` from your `.gitignore` file
+- **Option 2:** Ensure files that need to be read are not in `.gitignore` list
+
+**Related Issue:** [#75](https://github.com/cexll/myclaude/issues/75)
+
+---
+
+### Q3: `/dev` command parallel execution is very slow
+
+**Problem:**
+Using `/dev` command for simple features takes too long (over 30 minutes) with no visibility into task progress.
+
+**Solution:**
+1. **Check logs:** Review `C:\Users\User\AppData\Local\Temp\codeagent-wrapper-*.log` to identify bottlenecks
+2. **Adjust backend:**
+   - Try faster models like `gpt-5.1-codex-max`
+   - Running in WSL may be significantly faster
+3. **Workspace:** Use a single repository instead of monorepo with multiple sub-projects
+
+**Related Issue:** [#77](https://github.com/cexll/myclaude/issues/77)
+
+---
+
+### Q4: Codex permission denied with new Go version
+
+**Problem:**
+After upgrading to the new Go-based Codex implementation, execution fails with permission denied errors.
+
+**Solution:**
+Add the following configuration to `~/.codex/config.yaml` (Windows: `c:\user\.codex\config.toml`):
+```yaml
+model = "gpt-5.1-codex-max"
+model_reasoning_effort = "high"
+model_reasoning_summary = "detailed"
+approval_policy = "never"
+sandbox_mode = "workspace-write"
+disable_response_storage = true
+network_access = true
+```
+
+**Key settings:**
+- `approval_policy = "never"` - Remove approval restrictions
+- `sandbox_mode = "workspace-write"` - Allow workspace write access
+- `network_access = true` - Enable network access
+
+**Related Issue:** [#31](https://github.com/cexll/myclaude/issues/31)
+
+---
+
+### Q5: Permission denied or sandbox restrictions during execution
+
+**Problem:**
+Execution fails with permission errors or sandbox restrictions when running codeagent-wrapper.
+
+**Solution:**
+Set the following environment variables:
+```bash
+export CODEX_BYPASS_SANDBOX=true
+export CODEAGENT_SKIP_PERMISSIONS=true
+```
+
+Or add them to your shell profile (`~/.zshrc` or `~/.bashrc`):
+```bash
+echo 'export CODEX_BYPASS_SANDBOX=true' >> ~/.zshrc
+echo 'export CODEAGENT_SKIP_PERMISSIONS=true' >> ~/.zshrc
+```
+
+**Note:** These settings bypass security restrictions. Use with caution in trusted environments only.

+## 常见问题 (FAQ)
+
+### Q1: `codeagent-wrapper` 执行时报错 "Unknown event format"
+
+**问题描述：**
+执行 `codeagent-wrapper` 时出现错误：
+```
+Unknown event format: {"type":"turn.started"}
+Unknown event format: {"type":"assistant", ...}
+```
+
+**解决方案：**
+这是日志事件流的显示问题，不影响实际功能执行。预计在下个版本中修复。如需排查其他问题，可忽略此日志输出。
+
+**相关 Issue：** [#96](https://github.com/cexll/myclaude/issues/96)
+
+---
+
+### Q2: Gemini 无法读取 `.gitignore` 忽略的文件
+
+**问题描述：**
+使用 `codeagent-wrapper --backend gemini` 时，无法读取 `.claude/` 等被 `.gitignore` 忽略的目录中的文件。
+
+**解决方案：**
+- **方案一：** 在项目根目录的 `.gitignore` 中取消对 `.claude/` 的忽略
+- **方案二：** 确保需要读取的文件不在 `.gitignore` 忽略列表中
+
+**相关 Issue：** [#75](https://github.com/cexll/myclaude/issues/75)
+
+---
+
+### Q3: `/dev` 命令并行执行特别慢
+
+**问题描述：**
+使用 `/dev` 命令开发简单功能耗时过长（超过30分钟），无法了解任务执行状态。
+
+**解决方案：**
+1. **检查日志：** 查看 `C:\Users\User\AppData\Local\Temp\codeagent-wrapper-*.log` 分析瓶颈
+2. **调整后端：**
+   - 尝试使用 `gpt-5.1-codex-max` 等更快的模型
+   - 在 WSL 环境下运行速度可能更快
+3. **工作区选择：** 使用独立的代码仓库而非包含多个子项目的 monorepo
+
+**相关 Issue：** [#77](https://github.com/cexll/myclaude/issues/77)
+
+---
+
+### Q4: 新版 Go 实现的 Codex 权限不足
+
+**问题描述：**
+升级到新版 Go 实现的 Codex 后，出现权限不足的错误。
+
+**解决方案：**
+在 `~/.codex/config.yaml` 中添加以下配置（Windows: `c:\user\.codex\config.toml`）：
+```yaml
+model = "gpt-5.1-codex-max"
+model_reasoning_effort = "high"
+model_reasoning_summary = "detailed"
+approval_policy = "never"
+sandbox_mode = "workspace-write"
+disable_response_storage = true
+network_access = true
+```
+
+**关键配置说明：**
+- `approval_policy = "never"` - 移除审批限制
+- `sandbox_mode = "workspace-write"` - 允许工作区写入权限
+- `network_access = true` - 启用网络访问
+
+**相关 Issue：** [#31](https://github.com/cexll/myclaude/issues/31)
+
+---
+
+### Q5: 执行时遇到权限拒绝或沙箱限制
+
+**问题描述：**
+运行 codeagent-wrapper 时出现权限错误或沙箱限制。
+
+**解决方案：**
+设置以下环境变量：
+```bash
+export CODEX_BYPASS_SANDBOX=true
+export CODEAGENT_SKIP_PERMISSIONS=true
+```
+
+或添加到 shell 配置文件（`~/.zshrc` 或 `~/.bashrc`）：
+```bash
+echo 'export CODEX_BYPASS_SANDBOX=true' >> ~/.zshrc
+echo 'export CODEAGENT_SKIP_PERMISSIONS=true' >> ~/.zshrc
+```
+
+**注意：** 这些设置会绕过安全限制，请仅在可信环境中使用。

-## The 6 Steps
+## Step 0 + The 6 Steps
+
+### 0. Select Allowed Backends (FIRST ACTION)
+- Use **AskUserQuestion** with multiSelect to ask which backends are allowed for this run
+- Options (user can select multiple):
+  - `codex` - Stable, high quality, best cost-performance (default for most tasks)
+  - `claude` - Fast, lightweight (for quick fixes and config changes)
+  - `gemini` - UI/UX specialist (for frontend styling and components)
+- If user selects ONLY `codex`, ALL subsequent tasks must use `codex` (including UI/quick-fix)
 
 ### 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
+### 2. codeagent Analysis + Task Typing + UI Detection
 - Call codeagent to analyze the request in plan mode style
 - Extract: core functions, technical points, task list (2–5 items)
+- For each task, assign exactly one type: `default` / `ui` / `quick-fix`
 - 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
+- Include: task breakdown, `type`, 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)
+- Route backend per task type (with user constraints + fallback):
+  - `default` → `codex`
+  - `ui` → `gemini` (enforced when allowed)
+  - `quick-fix` → `claude`
+  - Missing `type` → treat as `default`
+  - If the preferred backend is not allowed, fallback to an allowed backend by priority: `codex` → `claude` → `gemini`
 - Independent tasks → run in parallel
 - Conflicting tasks → run serially

-## UI Auto-Detection & Backend Routing
+## Backend Selection & Routing
+- **Step 0**: user selects allowed backends; if `仅 codex`, all tasks use codex
 - **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
+- **Task type field**: each task in `dev-plan.md` must have `type: default|ui|quick-fix`

+description: Install Claude skills from GitHub repositories with automated security scanning. Triggers when users want to install skills from a GitHub URL, need to browse available skills in a repository, or want to safely add new skills to their Claude environment.
+---
+
+# Skill Install
+
+## Overview
+
+Install Claude skills from GitHub repositories with built-in security scanning to protect against malicious code, backdoors, and vulnerabilities.
+
+## When to Use
+
+Trigger this skill when the user:
+- Provides a GitHub repository URL and wants to install skills
+- Asks to "install skills from GitHub"
+- Wants to browse and select skills from a repository
+- Needs to add new skills to their Claude environment
+
+## Workflow
+
+### Step 1: Parse GitHub URL
+
+Accept a GitHub repository URL from the user. The URL should point to a repository containing a `skills/` directory.
+
+Supported URL formats:
+- `https://github.com/user/repo`
+- `https://github.com/user/repo/tree/main/skills`
+- `https://github.com/user/repo/tree/branch-name/skills`
+
+Extract:
+- Repository owner
+- Repository name
+- Branch (default to `main` if not specified)
+
+### Step 2: Fetch Skills List
+
+Use the WebFetch tool to retrieve the skills directory listing from GitHub.
+
+GitHub API endpoint pattern:
+```
+https://api.github.com/repos/{owner}/{repo}/contents/skills?ref={branch}
+```
+
+Parse the response to extract:
+- Skill directory names
+- Each skill should be a subdirectory containing a SKILL.md file
+
+### Step 3: Present Skills to User
+
+Use the AskUserQuestion tool to let the user select which skills to install.
+
+Set `multiSelect: true` to allow multiple selections.
+
+Present each skill with:
+- Skill name (directory name)
+- Brief description (if available from SKILL.md frontmatter)
+
+### Step 4: Fetch Skill Content
+
+For each selected skill, fetch all files in the skill directory:
+
+1. Get the file tree for the skill directory
+2. Download all files (SKILL.md, scripts/, references/, assets/)
+3. Store the complete skill content for security analysis
+
+Use WebFetch with GitHub API:
+```
+https://api.github.com/repos/{owner}/{repo}/contents/skills/{skill_name}?ref={branch}
+```
+
+For each file, fetch the raw content:
+```
+https://raw.githubusercontent.com/{owner}/{repo}/{branch}/skills/{skill_name}/{file_path}
+```
+
+### Step 5: Security Scan
+
+**CRITICAL:** Before installation, perform a thorough security analysis of each skill.
+
+Read the security scan prompt template from `references/security_scan_prompt.md` and apply it to analyze the skill content.
+
+Examine for:
+1. **Malicious Command Execution** - eval, exec, subprocess with shell=True
+2. **Backdoor Detection** - obfuscated code, suspicious network requests
+3. **Credential Theft** - accessing ~/.ssh, ~/.aws, environment variables
+4. **Unauthorized Network Access** - external requests to suspicious domains
+5. **File System Abuse** - destructive operations, unauthorized writes
+6. **Privilege Escalation** - sudo attempts, system modifications
+7. **Supply Chain Attacks** - suspicious package installations
+
+Output the security analysis with:
+- Security Status: SAFE / WARNING / DANGEROUS
+- Risk Level: LOW / MEDIUM / HIGH / CRITICAL
+- Detailed findings with file locations and severity
+- Recommendation: APPROVE / APPROVE_WITH_WARNINGS / REJECT
+
+### Step 6: User Decision
+
+Based on the security scan results:
+
+**If SAFE (APPROVE):**
+- Proceed directly to installation
+
+**If WARNING (APPROVE_WITH_WARNINGS):**
+- Display the security warnings to the user
+- Use AskUserQuestion to confirm: "Security warnings detected. Do you want to proceed with installation?"
+- Options: "Yes, install anyway" / "No, skip this skill"
+
+**If DANGEROUS (REJECT):**
+- Display the critical security issues
+- Refuse to install
+- Explain why the skill is dangerous
+- Do NOT provide an option to override for CRITICAL severity issues
+
+### Step 7: Install Skills
+
+For approved skills, install to `~/.claude/skills/`:
+
+1. Create the skill directory: `~/.claude/skills/{skill_name}/`
+2. Write all skill files maintaining the directory structure
+3. Ensure proper file permissions (executable for scripts)
+4. Verify SKILL.md exists and has valid frontmatter
+
+Use the Write tool to create files.
+
+### Step 8: Confirmation
+
+After installation, provide a summary:
+- List of successfully installed skills
+- List of skipped skills (if any) with reasons
+- Location: `~/.claude/skills/`
+- Next steps: "The skills are now available. Restart Claude or use them directly."
+
+## Example Usage
+
+**User:** "Install skills from https://github.com/example/claude-skills"
+
+**Assistant:**
+1. Fetches skills list from the repository
+2. Presents available skills: "skill-a", "skill-b", "skill-c"
+3. User selects "skill-a" and "skill-b"
+4. Performs security scan on each skill
+5. skill-a: SAFE - proceeds to install
+6. skill-b: WARNING (makes HTTP request) - asks user for confirmation
+7. Installs approved skills to ~/.claude/skills/
+8. Confirms: "Successfully installed: skill-a, skill-b"
+
+## Security Notes
+
+- **Never skip security scanning** - Always analyze skills before installation
+- **Be conservative** - When in doubt, flag as WARNING and let user decide
+- **Critical issues are blocking** - CRITICAL severity findings cannot be overridden
+- **Transparency** - Always show users what was found during security scans
+- **Sandboxing** - Remind users that skills run with Claude's permissions

+# Security Scan Prompt for Skills
+
+Use this prompt template to analyze skill content for security vulnerabilities before installation.
+
+## Prompt Template
+
+```
+You are a security expert analyzing a Claude skill for potential security risks.
+
+Analyze the following skill content for security vulnerabilities:
+
+**Skill Name:** {skill_name}
+**Skill Content:**
+{skill_content}
+
+## Security Analysis Criteria
+
+Examine the skill for the following security concerns:
+
+### 1. Malicious Command Execution
+- Detect `eval()`, `exec()`, `subprocess` with `shell=True`
+- Identify arbitrary code execution patterns
+- Check for command injection vulnerabilities
+
+### 2. Backdoor Detection

+- Identify suspicious network requests to unknown domains
+- Detect file hash patterns matching known malware
+- Check for hidden data exfiltration mechanisms
+
+### 3. Credential Theft
+- Detect attempts to access environment variables containing secrets
+- Identify file operations on sensitive paths (~/.ssh, ~/.aws, ~/.netrc)
+- Check for credential harvesting patterns
+- Look for keylogging or clipboard monitoring
+
+### 4. Unauthorized Network Access
+- Identify external network requests
+- Check for connections to suspicious domains (pastebin, ngrok, bit.ly, etc.)
+- Detect data exfiltration via HTTP/HTTPS
+- Look for reverse shell patterns
+
+### 5. File System Abuse
+- Detect destructive file operations (rm -rf, shutil.rmtree)
+- Identify unauthorized file writes to system directories
+- Check for file permission modifications
+- Look for attempts to modify critical system files
+
+### 6. Privilege Escalation
+- Detect sudo or privilege escalation attempts
+- Identify attempts to modify system configurations
+- Check for container escape patterns
+
+### 7. Supply Chain Attacks
+- Identify suspicious package installations
