Skill Review Skill

Process

Invoke: /review-skill <skill-name> or use this skill when detecting outdated patterns

Production evidence: better-auth audit (2025-11-08) - found 6 critical issues including non-existent API imports, removed 665 lines incorrect code, implemented v2.0.0

9-Phase Audit

1. Pre-Review: Install skill, check version/date, test discovery
2. Standards: Validate YAML, keywords, third-person style, directory structure
3. Official Docs: WebFetch/Context7 verify API patterns, GitHub updates, npm versions, production repos
4. Code Examples: Verify imports exist, API signatures match, schema consistency, templates work
5. Cross-File Consistency: Compare SKILL.md vs README.md, bundled resources match files
6. Dependencies: Run ./scripts/check-versions.sh, check breaking changes, verify "Last Verified"
7. Categorize: Severity (🔴 Critical / 🟡 High / 🟠 Medium / 🟢 Low) with evidence (GitHub/docs/npm)
8. Fix: Auto-fix unambiguous, ask user for architectural, update all files, bump version
9. Verify: Test discovery, templates work, no contradictions, commit with changelog

Automated (via ./scripts/review-skill.sh): YAML syntax, package versions, broken links, TODOs, file org, staleness

Manual (AI): API methods vs docs, GitHub issues, production comparisons, code correctness, schema consistency

Severity Classification

🔴 CRITICAL: Non-existent API/imports, invalid config, missing dependencies

🟡 HIGH: Contradictory examples, inconsistent patterns, outdated major versions

🟠 MEDIUM: Stale minors (>90d), missing docs sections, incomplete errors

🟢 LOW: Typos, formatting, missing optional metadata

Fix Decision

Auto-fix: Unambiguous (correct import from docs), clear evidence, no architectural impact

Ask user: Multiple valid approaches, breaking changes, architectural choices

Version Bumps

• Major (v1→v2): API patterns change
• Minor (v1.0→v1.1): New features, backward compatible
• Patch (v1.0.0→v1.0.1): Bug fixes only

Example: better-auth Audit (2025-11-08)

🔴 CRITICAL #1: Non-existent d1Adapter import from 'better-auth/adapters/d1'
- Evidence: Official docs show drizzleAdapter, GitHub has no d1Adapter export, 4 production repos use Drizzle/Kysely
- Fix: Replaced with drizzleAdapter from 'better-auth/adapters/drizzle'

Result: 3 files deleted (obsolete), 3 created (correct patterns), +1,266 lines, v1.0→v2.0, 3.5 hours

Issues Prevented (10)

1. Fake API adapters - Non-existent imports
2. Stale API methods - Changed signatures
3. Schema inconsistency - Different table names
4. Outdated scripts - Deprecated approaches
5. Version drift - Packages >90 days old
6. Contradictory examples - Multiple conflicting patterns
7. Broken links - 404 URLs
8. YAML errors - Invalid frontmatter
9. Missing keywords - Poor discoverability
10. Incomplete bundled resources - Listed files don't exist
