-## 6个步骤
+## The 6 Steps
 
-### 1. 需求澄清
-- 使用 **AskUserQuestion** 直接问用户
-- 无评分系统，无复杂逻辑
-- 2-3 轮问答直到需求明确
+### 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. 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
+### 2. Codex Analysis
+- Call codex to analyze the request
+- Extract: core functions, technical points, task list (2–5 items)
+- Output a structured analysis
 
-### 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
+### 3. Generate Dev Doc
+- Call the **develop-doc-generator** agent
+- Produce a single `dev-plan.md`
+- Include: task breakdown, file scope, dependencies, test commands
 
-### 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
+### 4. Concurrent Development
+- Work from the task list in dev-plan.md
+- Independent tasks → run in parallel
+- Conflicting tasks → run serially
 
-### 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%）
+### 5. Testing & Verification
+- Each codex task:
+  - Implements the feature
+  - Writes tests
+  - Runs coverage
+  - Reports results (≥90%)
 
-### 6. 完成
-- 汇总任务状态
-- 记录覆盖率
+### 6. Complete
+- Summarize task status
+- Record coverage
 
-## 使用方法
+## Usage
 
 ```bash
-/dev "实现用户登录功能，支持邮箱和密码验证"
+/dev "Implement user login with email + password"
 ```
 
-**无选项**，流程固定，开箱即用。
+**No options**, fixed workflow, works out of the box.

-## 示例
+## Example
 
 ```bash
-# 触发
-/dev "添加用户登录功能"
+# Trigger
+/dev "Add user login feature"
 
-# 步骤 1: 需求澄清
-Q: 支持哪些登录方式？
-A: 邮箱 + 密码
-Q: 需要记住登录状态吗？
-A: 是，使用 JWT token
+# Step 1: Clarify requirements
+Q: What login methods are supported?
+A: Email + password
+Q: Should login be remembered?
+A: Yes, use JWT token
 
-# 步骤 2: Codex 分析
-输出：
-- 核心功能：邮箱密码登录 + JWT认证
-- 任务 1：后端 API
-- 任务 2：密码加密
-- 任务 3：前端表单
+# Step 2: Codex analysis
+Output:
+- Core: email/password login + JWT auth
+- Task 1: Backend API
+- Task 2: Password hashing
+- Task 3: Frontend form

-## 设计原则
+## Design Principles
 
-1. **KISS**：保持简单愚蠢
-2. **即用即抛**：无持久化配置
-3. **质量优先**：强制 90% 覆盖率
-4. **并发优先**：充分利用 codex 能力
-5. **无历史包袱**：全新设计，不受其他项目影响
+1. **KISS**: keep it simple
+2. **Disposable**: no persistent config
+3. **Quality first**: enforce 90% coverage
+4. **Concurrency first**: leverage codex
+5. **No legacy baggage**: clean-slate design

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.
+**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.

 ## 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)
+- **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
