+- 2-3 轮问答直到需求明确
+
+### 2. Codex 分析
+- 调用 codex 分析需求
+- 提取：核心功能、技术要点、任务列表（2-5个）
+- 输出结构化分析结果
+
+### 3. 生成开发文档
+- 调用 **develop-doc-generator** agent
+- 生成 `dev-plan.md`（单一开发文档）
+- 包含：任务分解、文件范围、依赖关系、测试命令
+
+### 4. 并发开发
+- 基于 dev-plan.md 的任务列表
+- 无依赖任务 → 并发执行
+- 有冲突任务 → 串行执行
+
+### 5. 测试验证
+- 每个 codex 任务自己：
+  - 实现功能
+  - 编写测试
+  - 运行覆盖率
+  - 报告结果（≥90%）
+
+### 6. 完成
+- 汇总任务状态
+- 记录覆盖率
+
+## 使用方法
+
+```bash
+/dev "实现用户登录功能，支持邮箱和密码验证"
+```
+
+**无选项**，流程固定，开箱即用。
+
+## 输出结构
+
+```

+---
+
+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
+- Codex analysis results (feature highlights, task decomposition)
+- 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} - 开发计划
+
+## 功能概述
+[一句话描述核心功能]
+
+## 任务分解
+
+### 任务 1: [任务名称]
+- **ID**: task-1
+- **描述**: [具体要做什么]
+- **文件范围**: [涉及的目录或文件，如 src/auth/**, tests/auth/]
+- **依赖**: [无 或 依赖 task-x]
+- **测试命令**: [如 pytest tests/auth --cov=src/auth --cov-report=term]
+- **测试重点**: [需要覆盖的场景]
+
+### 任务 2: [任务名称]
+...
+
+（2-5个任务）
+
+## 验收标准
+- [ ] 功能点 1
+- [ ] 功能点 2
+- [ ] 所有单元测试通过
+- [ ] 代码覆盖率 ≥90%
+
+## 技术要点
+- [关键技术决策]
+- [需要注意的约束]
+```
+
+## 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 ("无" or "依赖 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 Codex analysis results
+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, 描述, 文件范围, 依赖, 测试命令, 测试重点)
+- [ ] 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
+- **Chinese Language**: The document must be in Chinese (as shown in the structure)
+- **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 codex 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 Codex
+  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
+  - Iterate 2-3 rounds until clear; rely on judgment; keep questions concise
+
+- **Step 2: Codex Analysis**
+  - Run:
+    ```bash
+    uv run ~/.claude/skills/codex/scripts/codex.py "分析以下需求并提取开发要点：

+       - 涉及文件/目录
+       - 是否依赖其他任务
+       - 测试重点
+    " "gpt-5.1-codex"
+    ```
+  - Extract core functionality, technical key points, and 2-5 parallelizable tasks with full metadata
+
+- **Step 3: Generate Development Documentation**
+  - invoke agent dev-plan-generator:
+    ```
+    基于以下分析结果生成开发文档：
+
+    [Codex 分析输出]
+
+    输出文件：./.claude/specs/{feature_name}/dev-plan.md

+    3. 验收标准
+    4. 覆盖率要求：≥90%
+    ```
+
+- **Step 4: Parallel Development Execution**
+  - For each task in `dev-plan.md` run:
+    ```bash
+    uv run ~/.claude/skills/codex/scripts/codex.py "实现任务：[任务ID]
+
+    参考文档：@.claude/specs/{feature_name}/dev-plan.md

+    文件范围：[任务的文件范围]
+    测试命令：[任务指定的测试命令]
+    覆盖率目标：≥90%
+    " "gpt-5.1-codex"
+    ```
+  - 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**
+- Codex 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
+- Prioritize speed via parallelization while enforcing coverage validation

-**推荐方式**（使用 uv run，自动管理 Python 环境）：
+**Mandatory**: Run every automated invocation through the Bash tool in the foreground with the command below, keeping the `timeout` parameter fixed at `7200000` milliseconds (do not change it or use any other entry point).
 ```bash

+**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.

 ### Invocation Pattern
 
-When calling via Bash tool, always include the timeout parameter:
+All automated executions may only invoke `uv run ~/.claude/skills/codex/scripts/codex.py "<task>" ...` through the Bash tool in the foreground, and the `timeout` must remain fixed at `7200000` (non-negotiable):

+- command: uv run ~/.claude/skills/codex/scripts/codex.py "<task>" [working_dir]
 - timeout: 7200000
 - description: <brief description of the task>

+### Large Task Protocol
+
+- For every large task, first produce a canonical task list that enumerates the Task ID, description, file/directory scope, dependencies, test commands, and the expected Codex Bash invocation.
+- Tasks without dependencies should be executed concurrently via multiple foreground Bash calls (you can keep separate terminal windows) and each run must log start/end times plus any shared resource usage.
+- Reuse context aggressively (such as @spec.md or prior analysis output), and after concurrent execution finishes, reconcile against the task list to report which items completed and which slipped.
+
+| ID | Description | Scope | Dependencies | Tests | Command |
+| --- | --- | --- | --- | --- | --- |
+| T1 | Review @spec.md to extract requirements | docs/, @spec.md | None | None | uv run ~/.claude/skills/codex/scripts/codex.py "analyze requirements @spec.md" |
+| T2 | Implement the module and add test cases | src/module | T1 | npm test -- --runInBand | uv run ~/.claude/skills/codex/scripts/codex.py "implement and test @src/module" |
+
 ## Notes
 
 - **Recommended**: Use `uv run` for automatic Python environment management (requires uv installed)
 - **Alternative**: Direct execution `./codex.py` (uses system Python via shebang)
 - Python implementation using standard library (zero dependencies)
+- All automated runs must use the Bash tool with the fixed timeout to provide dual timeout protection and unified logging/exit semantics; any alternative approach is limited to manual foreground execution.
 - Cross-platform compatible (Windows/macOS/Linux)
 - PEP 723 compliant (inline script metadata)
 - Runs with `--dangerously-bypass-approvals-and-sandbox` for automation (new sessions only)

+name: gemini
+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
