Tools

Use the project's specific technology stack including Next.js, React, TypeScript, Hono, PostgreSQL, Chakra UI, and Temporal for workflow automation. When setting up new features, choosing libraries, or making architectural decisions. When working on frontend code using React and Next.js. When implementing backend APIs with Hono. When working with PostgreSQL databases via Drizzle or Prisma. When styling with Chakra UI components. When implementing authentication with better-auth or workflows with Temporal. When adding dependencies or configuring build tools. This skill ensures technology choices align with the project's established stack.

Orchestrates complete Story workflow from task planning to Done. Delegates to ln-300-task-coordinator, ln-310-story-validator, ln-410-story-executor for full automation.

Comment on GitHub issues using the gh CLI. Use when Codex needs to share an implementation plan, progress update, or blockers. Always read the issue body and comments for context, optionally read related issues, and only create or update Codex-owned comments.

Use when monitoring code quality over time, measuring refactoring impact, tracking if complexity is improving or worsening, or validating technical debt work - tracks complexity metrics across git history identifying improving, stable, or deteriorating files

Task decomposition with integrated validation via Codex clink. Guides task-decomposer through BUILD-PLAN creation, mandatory validation gate, and fix loop. Use when creating build plans, decomposing blueprints into tasks, or validating task granularity. Triggers on build plan, task decomposition, B1 phase, decompose blueprint, atomic tasks.

PCE (Process-Context Engine) のタスク分解スキル。親→子→孫の入れ子構造でタスクを分解し、各プロセスへのコンテキスト継承を設計する。 トリガー条件: - 大きなタスクを受け取った時 - 「このタスクを分解して」 - 「実装計画を立てて」 - 「作業を整理して」 - 複雑な機能の実装開始時

技術検証（Tech Spike）ワークフロー。ライブラリ選定やアーキテクチャ判断の前に最小限の実験コードで技術的妥当性を検証。 使用タイミング: (1) 複数の技術選択肢がある場合（ライブラリA vs B） (2) 新しいライブラリ・技術の学習コストが高い場合 (3) パフォーマンス・互換性の懸念がある場合 (4) 既存システムとの統合リスクがある場合 (5) 「技術検証」「ライブラリ調査」「スパイク」リクエスト 使用しない場合: 技術スタック確定済み、既知のパターン、単純なCRUD操作

DevOps automation for a Next.js (Vercel) frontend, Fly.io backend, and Supabase Postgres. The agent should prefer `just` recipes as the invocation surface. Internally, recipes use a hybrid MCP+CLI approach: Supabase CLI for writes/migrations (local & prod), Fly MCP preferred for ops with flyctl fallback, and Vercel CLI for deploy with optional MCP for env/status. Secrets are loaded exclusively via 1Password CLI; values are never printed.

Guia completo de MUI V7 para React + TypeScript. Ensina migração V6→V7, design responsivo avançado, theming profissional, padrões de componentes e detecção automática de sintaxe antiga. Use quando criar dashboards, interfaces modernas, ou trabalhar com Material-UI/MUI.

TDD의 Refactor 단계 전용 스킬. 테스트가 통과하는 상태를 유지하면서 코드 품질을 개선합니다. 중복 제거, 명확성 향상, 성능 최적화에 사용.

This skill guides working with Neovim configuration including testing changes headlessly, managing plugins with lazy.nvim, configuring LSP servers, and troubleshooting startup errors. Use this when modifying nvim config files or debugging nvim issues.

This skill should be used when creating token-efficient hook systems and MCP server architectures for web applications. Use for React/FastAPI, Django, Node.js projects that need smart caching, progressive context loading, and 95%+ token reduction. Essential for projects requiring monitoring, debugging, data analysis, and system health tools.

Capture and apply continuous improvements to Codex CLI skills during regular work. Use when a user wants to refine a skill, add a new skill after repeating a workflow, or keep skills up to date based on recent tasks.

Domain-Driven Design patterns and architecture for Deno TypeScript applications. Use when building complex business logic, implementing bounded contexts, or structuring large-scale Deno applications with clear separation of concerns.

Automatically generate test scaffolding when user writes new code without tests or mentions needing tests. Supports unit, integration, e2e, and data tests for PHP and JavaScript. Invoke when user mentions "tests", "testing", "coverage", "write tests", or shows new untested code.

This skill should be used when orchestrating multiple skills together for complex workflows. Triggers include "chain these skills", "use X then Y skill", "multi-skill workflow", or when a task requires capabilities from several skills. Handles skill sequencing, data flow, and aggregated validation.
