Purpose

This skill provides systematic checklists for code review and pre-commit verification.

Quick Reference

Comment Prefixes

Prefix	Meaning	Action Required
❗ BLOCKING	Must fix before merge	🔴 Required
⚠️ IMPORTANT	Should fix, but not blocking	🟡 Recommended
💡 SUGGESTION	Nice-to-have improvement	🟢 Optional
❓ QUESTION	Need clarification	🔵 Discuss
📝 NOTE	Informational, no action	⚪ Informational

Review Checklist Categories

1. Functionality - Does it work?
2. Design - Right architecture?
3. Quality - Clean code?
4. Readability - Easy to understand?
5. Tests - Adequate coverage?
6. Security - No vulnerabilities?
7. Performance - Efficient?
8. Errors - Properly handled?
9. Docs - Updated?
10. Dependencies - Necessary?

Pre-Commit Checklist

• Build succeeds (zero errors, zero warnings)
• All tests pass
• Code follows project standards
• No security vulnerabilities
• Documentation updated
• Branch synced with target

Detailed Guidelines

For complete standards, see:

• Review Checklist
• Pre-Commit Checklist

AI-Optimized Format (Token-Efficient)

For AI assistants, use the YAML format file for reduced token usage:

• Base standard: ai/standards/code-review.ai.yaml

Example Review Comments

❗ BLOCKING: Potential SQL injection vulnerability here.
Please use parameterized queries instead of string concatenation.

⚠️ IMPORTANT: This method is doing too much (120 lines).
Consider extracting validation logic to a separate method.

💡 SUGGESTION: Consider using a Map here instead of an array for O(1) lookup.

❓ QUESTION: Why are we using setTimeout here instead of async/await?

📝 NOTE: This is a clever solution! Nice use of reduce here.

Core Principles

1. Be Respectful - Review code, not the person
2. Be Thorough - Check functionality, not just syntax
3. Be Timely - Review within 24 hours
4. Be Clear - Explain WHY, not just WHAT

Checkin Quality Gates (YAML Compressed)

# === MANDATORY CHECKLIST ===
build:
  - code_compiles: "zero errors, zero warnings"
  - dependencies: "all installed, versions locked"
  verify: "run build locally, exit code 0"

test:
  - existing_pass: "100% pass rate (unit/integration/e2e)"
  - new_code_tested: "features→tests, bugfix→regression"
  - coverage: "not decreased, critical paths tested"
  verify: "run all suites, review coverage report"

quality:
  - standards: "naming, formatting, comments"
  - no_smells: "methods≤50 lines, nesting≤3, complexity≤10, no duplication"
  - security: "no hardcoded secrets, no SQLi, no XSS, no insecure deps"
  verify: "run linter, static analysis, security scanner"

docs:
  - api_docs: "public APIs documented"
  - readme: "updated if needed"
  - changelog: "user-facing changes → [Unreleased]"

workflow:
  - branch_naming: "feature/, fix/, docs/, chore/"
  - commit_message:

Configuration Detection

This skill supports project-specific configuration.

Detection Order

1. Check CONTRIBUTING.md for "Disabled Skills" section
   • If this skill is listed, it is disabled for this project
2. Check CONTRIBUTING.md for "Code Review Language" section
3. If not found, default to English

First-Time Setup

If no configuration found and context is unclear:

1. Ask the user: "This project hasn't configured code review language. Which option would you like? (English / 中文)"
2. After user selection, suggest documenting in CONTRIBUTING.md:

## Code Review Language

This project uses **[chosen option]** for code review comments.
<!-- Options: English | 中文 -->

Configuration Example

In project's CONTRIBUTING.md:

## Code Review Language

This project uses **English** for code review comments.
<!-- Options: English | 中文 -->
