What this skill does


# Best Practices Extractor

Extract coding best practices from PR review comments and codebase analysis to generate `.claude/best-practices/` documentation.

## When to Use

- Initial setup of coding standards for a project
- Regular updates to capture new team feedback
- Analyzing PR comments to document patterns
- Generating best practices from code review history

## Extraction Methods

All outputs are saved to `.claude/pr-review-comments/`.

### Method 1: Incremental Update (Recommended)

For regular updates - fast and tracks state:

```bash
cd plugin/skills/best-practices-extractor
bash scripts/incremental_update.sh OWNER REPO_NAME
```

First run does full extraction; subsequent runs fetch only new PRs.

**Output**: `.claude/pr-review-comments/{repo}_inline_comments.ndjson`

### Method 2: Full Extraction

For first-time setup or comprehensive analysis:

```bash
bash scripts/extract_pr_comments.sh REPO_NAME
```

**Output**: `.claude/pr-review-comments/{repo}_inline_comments.ndjson`

### Method 3: Sort by File Tree

Organize extracted comments by directory structure:

```bash
bash scripts/sort_comments_by_filetree.sh .claude/pr-review-comments/{repo}_inline_comments.ndjson
```

**Output**: `.claude/pr-review-comments/sorted/`

## Generating Best Practices

After extracting comments:

1. **Identify patterns** - Look for recurring feedback themes
2. **Categorize** - Group by type (naming, error-handling, type-safety, etc.)
3. **Create documentation** - Generate `.claude/best-practices/` files

### Output Structure

```
.claude/best-practices/
├── README.md              # Index
├── naming-conventions.md
├── error-handling.md
├── type-safety.md
├── testing.md
└── ...
```

### Guideline Format

Each guideline should include:

```markdown
## [Number]. [Title]

**Guideline:** [Clear statement]

**Why:** [Impact explanation]

**Example:**
```typescript
// Good
{example}

// Bad
{counter_example}
```

**Source:** PR #{number}
```

## Prerequisites

- **GitHub CLI (`gh`)**: Authenticated - check with `gh auth status`
- **jq**: JSON processor - check with `jq --version`

## Integration

This skill **generates** best practices. The `code-reviewer` agent and `/4_review` command **validate** against them.

Workflow:
1. Extract PR comments (this skill)
2. Analyze and generate `.claude/best-practices/`
3. Reviews automatically validate against best practices
