Use when implementing features, fixing bugs, or writing any production code - enforces RED-GREEN-REFACTOR cycle where tests must fail before writing implementation code. Activates before coding begins.
Defines project-wide code conventions for magic number elimination, constant usage, performance optimization, and type safety. Use when implementing, testing, or reviewing code to ensure consistency across the codebase.
Validate and auto-fix Python linting, formatting, and type issues using ruff and ty
Verifies code and configurations comply with security standards and regulations
Apply when writing React/TypeScript frontend code. Enforces component architecture patterns, type safety, and reusability standards.
Self-review after code changes. Use proactively after completing any code modifications, before creating a pull request. Runs tests, checks code quality, and validates changes.
Delegates coding standards violation scanning to a lightweight agent. Use when checking files for violations without loading full source files into context.
Detect and resolve incoherence in documentation, code, specs vs implementation. Includes reconciliation phase for applying user-provided resolutions.
チーム開発向けの汎用コーディング規約・設計/実装/テストレビュー観点を即時提示する。 設計前のプランニングと、実装/テスト後のゲートチェックで起動し、重要度（★3〜0）付きのチェックリストと指摘を返す。
Use when adding type hints, fixing type checker errors, working with Pydantic models. Triggers on "type", "types", "typing", "Pydantic", "BaseModel", "pyright", "basedpyright", "mypy", "type error", "type hint", "annotation", "Any", "dict", "list", "Optional", "Cannot assign", "Incompatible types", "Missing return type", "reportArgumentType", or when defining function signatures or data models.
Gitコミット前に自動で品質チェックを実行するスキル。 「この修正をコミットして」「コードレビューしてからコミットして」などの依頼に対応し、 ESLint/BlackによるLint、テスト実行、コードレビューを自動実行後、 Conventional Commits準拠のコミットメッセージでコミットを作成する。 プッシュやPR作成は行わず、ローカルコミットまでを実行する。
Review pull requests using team coding standards. Triggers: review PR, check pull request, PR review, code review standards, review my changes, check my PR
Validates WCAG AA contrast ratios (minimum 4.5:1) for text and background color combinations in frontend code. Use when reviewing UI implementations to ensure accessibility compliance and catch poor contrast before deployment.
3-Way並列コードレビュー（Codex CLI + Gemini CLI + Claude Code Task agent）。複数視点での品質チェック、アーキテクチャ決定、デバッグ、セカンドオピニオンが必要な場合に使用。
Install pre-commit hooks to automatically lint markdown files before commits
Skill para revisão de código com foco em qualidade, segurança e melhores práticas
Conduct comprehensive code reviews using software engineering best practices, clean code principles (SOLID, DRY, KISS, YAGNI), security checks, and performance analysis. Use when reviewing code changes, pull requests, new implementations, or entire files for quality, maintainability, security, and performance. Provides structured findings with severity levels and actionable recommendations.
Create custom Semgrep rules for vulnerability detection. Use when writing new rules for specific vulnerability patterns, creating org-specific detections, or building rules for novel attack vectors discovered during bug bounty hunting.
Verify code is ready for production - build, tests, security, and configuration checks
Review code for Playwright Guidelines compliance. Use when asked to "review my playwright tests", "check accessibility", or "check my tests against best practices".
Checklist for security-sensitive coding, ensuring MaiHouses guards and policies are respected.
