### Update: ./CLAUDE.md
**Why:** [Brief explanation of why this helps]

```diff
+ ## Quick Start
+
+ ```bash
+ npm install
+ npm run dev
+ ```

### Phase 5: Apply Updates

After user approval, use Edit tool to apply changes. Preserve existing content structure.

## Examples

### Example 1: Quality Assessment

**User request:** "Check if my CLAUDE.md is good"

**Response:**
```markdown
## CLAUDE.md Quality Report

### Summary
- Files found: 1
- Average score: 65/100
- Files needing update: 1

### File-by-File Assessment

#### 1. ./CLAUDE.md
**Score: 65/100 (Grade: C)**

| Criterion | Score | Notes |
|-----------|-------|-------|
| Commands/workflows | 10/20 | Only npm install documented |
| Architecture clarity | 15/20 | Basic tree, missing module relationships |
| Non-obvious patterns | 5/15 | No gotchas documented |
| Conciseness | 15/15 | Concise and dense |
| Currency | 10/15 | Some outdated paths |
| Actionability | 10/15 | Some vague instructions |

**Issues:**
- Missing test command
- Missing build command
- No documentation of auth flow complexity
- References to old src/structure

**Recommended additions:**
- Add Commands section with test/build
- Document auth module gotcha
- Update architecture paths

I'll create a CLAUDE.md for your React project. Let me first analyze the codebase structure.

## CLAUDE.md Quality Report

### Summary
- Files found: 0
- Creating new CLAUDE.md at project root

### Proposed CLAUDE.md Content:

# Project Name

## Commands

| Command | Description |
|---------|-------------|
| `npm install` | Install dependencies |
| `npm run dev` | Start dev server (Vite on port 5173) |
| `npm run build` | Production build |
| `npm run test` | Run Vitest tests |
| `npm run lint` | ESLint check |

## Architecture

## Gotchas

- Vite requires files in `public/` for static assets
- State updates in `useEffect` need proper dependency arrays

### Example 3: Update Proposal

**User request:** "Update my CLAUDE.md with what you learned"

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

**Why:** Discovered that tests require database setup which wasn't documented.

```diff
## Testing

+ **Prerequisites:** Start test database first with `docker-compose up -d test-db`
+ `npm run test` - Run all tests
+ `npm run test:unit` - Unit tests only (no DB required)

## Environment

- `API_BASE_URL` - API endpoint (default: localhost:3000)
+ `API_BASE_URL` - API endpoint (required for production, defaults to http://localhost:3000 in dev)

## Best Practices

1. **Always read references before acting**: Quality criteria, templates, and update guidelines contain essential details
2. **Report before editing**: Never modify CLAUDE.md without first presenting a quality report
3. **Preserve existing structure**: When updating, maintain the existing organization and style
4. **Be project-specific**: Only add information specific to this codebase, not generic advice
5. **Verify commands work**: Before suggesting commands, mentally or actually verify they execute correctly
6. **Use progressive disclosure**: Keep SKILL.md lean, reference detailed rubrics in separate files
7. **Score consistently**: Apply the same scoring standards across all files for fair comparison

## Constraints and Warnings

1. **Never modify without approval**: Always get user confirmation before editing CLAUDE.md files
2. **Don't remove content without asking**: If suggesting deletions, explicitly mark them and get approval
3. **Respect `.claude.local.md`**: These are personal settings; never suggest modifying them in shared docs
4. **Avoid generic advice**: Do not add "write good code" type content - focus on project-specific patterns
5. **Keep diffs concise**: Show only the actual changes, not entire file contents
6. **Verify file paths**: Ensure all referenced files exist before documenting them
7. **Score objectively**: Use the rubric consistently; don't inflate scores for incomplete documentation
