### 导出副本边界与技能别名

迁移、安装、修复和经验回写只作用于当前加载的目标宿主技能副本。原 Codex 技能/MCP、下载的源码和 `original-skills` 均为来源材料，不因执行本副本而写入；只有用户另行明确要求配置 Codex 产品本身时，才按该产品流程处理指定目标。脚本需要安装目录或状态目录时，显式提供目标路径；不得从 `CODEX_HOME` 隐式推断写入位置。

跨技能名称可能沿用源库别名。先查 [技能别名表](../../skill-aliases.json)，优先选择同来源、同插件的条目，再使用其 `id` 调用或读取对应入口；不得假定旧 `$skill`、`superpowers:skill` 名称在新宿主直接注册。不能确定目标时先核对，不替换真实产品命令或 Shell 环境变量。

## 跨宿主使用约定

本副本供支持 Agent Skills 的客户端使用。先检查当前宿主实际提供的工具、权限和已连接服务，再执行正文工作流。原文中的宿主工具标识是能力参考；只有实际发现该工具时才可调用，其他宿主应使用经核验的等价 MCP、CLI 或 API。没有等价能力的步骤必须报告不可用，不能虚构调用或完成状态。

技能资源以本技能目录为基准；输出写入当前项目中用户指定的位置。通过技能名称或自然语言触发，具体快捷命令由宿主决定。涉及真实产品、模型 API、协议字段和官方网址的名称保持原意。授权、审批、隐私和工具范围限制在迁移后仍然有效；不得为兼容而扩大权限。具体依赖与迁移说明见同目录 `PORTABILITY.md`。

# CLAUDE.md Improver

Audit, evaluate, and improve CLAUDE.md files across a codebase to ensure Claude Code has optimal project context.

**This skill can write to CLAUDE.md files.** After presenting a quality report and getting user approval, it updates CLAUDE.md files with targeted improvements.

## Workflow

### Phase 1: Discovery

Find all CLAUDE.md files in the repository:

```bash
find . -name "CLAUDE.md" -o -name ".claude.md" -o -name ".claude.local.md" 2>/dev/null | head -50
```

**File Types & Locations:**

| Type | Location | Purpose |
|------|----------|---------|
| Project root | `./CLAUDE.md` | Primary project context (checked into git, shared with team) |
| Local overrides | `./.claude.local.md` | Personal/local settings (gitignored, not shared) |
| Global defaults | `~/.claude/CLAUDE.md` | User-wide defaults across all projects |
| Package-specific | `./packages/*/CLAUDE.md` | Module-level context in monorepos |
| Subdirectory | Any nested location | Feature/domain-specific context |

**Note:** Claude auto-discovers CLAUDE.md files in parent directories, making monorepo setups work automatically.

### Phase 2: Quality Assessment

For each CLAUDE.md file, evaluate against quality criteria. See [references/quality-criteria.md](references/quality-criteria.md) for detailed rubrics.

**Quick Assessment Checklist:**

| Criterion | Weight | Check |
|-----------|--------|-------|
| Commands/workflows documented | High | Are build/test/deploy commands present? |
| Architecture clarity | High | Can Claude understand the codebase structure? |
| Non-obvious patterns | Medium | Are gotchas and quirks documented? |
| Conciseness | Medium | No verbose explanations or obvious info? |
| Currency | High | Does it reflect current codebase state? |
| Actionability | High | Are instructions executable, not vague? |

**Quality Scores:**
- **A (90-100)**: Comprehensive, current, actionable
- **B (70-89)**: Good coverage, minor gaps
- **C (50-69)**: Basic info, missing key sections
- **D (30-49)**: Sparse or outdated
- **F (0-29)**: Missing or severely outdated

### Phase 3: Quality Report Output

**ALWAYS output the quality report BEFORE making any updates.**

Format:

```
## CLAUDE.md Quality Report

### Summary
- Files found: X
- Average score: X/100
- Files needing update: X

### File-by-File Assessment

#### 1. ./CLAUDE.md (Project Root)
**Score: XX/100 (Grade: X)**

| Criterion | Score | Notes |
|-----------|-------|-------|
| Commands/workflows | X/20 | ... |
| Architecture clarity | X/20 | ... |
| Non-obvious patterns | X/15 | ... |
| Conciseness | X/15 | ... |
| Currency | X/15 | ... |
| Actionability | X/15 | ... |

**Issues:**
- [List specific problems]

**Recommended additions:**
- [List what should be added]

#### 2. ./packages/api/CLAUDE.md (Package-specific)
...
```

### Phase 4: Targeted Updates

After outputting the quality report, ask user for confirmation before updating.

**Update Guidelines (Critical):**

1. **Propose targeted additions only** - Focus on genuinely useful info:
   - Commands or workflows discovered during analysis
   - Gotchas or non-obvious patterns found in code
   - Package relationships that weren't clear
   - Testing approaches that work
   - Configuration quirks

2. **Keep it minimal** - Avoid:
   - Restating what's obvious from the code
   - Generic best practices already covered
   - One-off fixes unlikely to recur
   - Verbose explanations when a one-liner suffices

3. **Show diffs** - For each change, show:
   - Which CLAUDE.md file to update
   - The specific addition (as a diff or quoted block)
   - Brief explanation of why this helps future sessions

**Diff Format:**

```markdown
### Update: ./CLAUDE.md

**Why:** Build command was missing, causing confusion about how to run the project.

```diff
+ ## Quick Start
+
+ ```bash
+ npm install
+ npm run dev  # Start development server on port 3000
+ ```
```
```

### Phase 5: Apply Updates

After user approval, apply changes using the Edit tool. Preserve existing content structure.

## Templates

See [references/templates.md](references/templates.md) for CLAUDE.md templates by project type.

## Common Issues to Flag

1. **Stale commands**: Build commands that no longer work
2. **Missing dependencies**: Required tools not mentioned
3. **Outdated architecture**: File structure that's changed
4. **Missing environment setup**: Required env vars or config
5. **Broken test commands**: Test scripts that have changed
6. **Undocumented gotchas**: Non-obvious patterns not captured

## User Tips to Share

When presenting recommendations, remind users:

- **`#` key shortcut**: During a Claude session, press `#` to have Claude auto-incorporate learnings into CLAUDE.md
- **Keep it concise**: CLAUDE.md should be human-readable; dense is better than verbose
- **Actionable commands**: All documented commands should be copy-paste ready
- **Use `.claude.local.md`**: For personal preferences not shared with team (add to `.gitignore`)
- **Global defaults**: Put user-wide preferences in `~/.claude/CLAUDE.md`

## What Makes a Great CLAUDE.md

**Key principles:**
- Concise and human-readable
- Actionable commands that can be copy-pasted
- Project-specific patterns, not generic advice
- Non-obvious gotchas and warnings

**Recommended sections** (use only what's relevant):
- Commands (build, test, dev, lint)
- Architecture (directory structure)
- Key Files (entry points, config)
- Code Style (project conventions)
- Environment (required vars, setup)
- Testing (commands, patterns)
- Gotchas (quirks, common mistakes)
- Workflow (when to do what)
