Data & AI

REST APIs, GraphQL, FastAPI, data service design, and integration

Use this skill when implementing, modifying, or fixing ANY scraper, discovery, or extraction code in the packages/scrapers directory. Triggers for tasks involving SmartDiscoveryAgent, SmartDishFinderAgent, PuppeteerFetcher, search engines, platform adapters, or related components. Orchestrates a rigorous test-driven workflow with use case definition BEFORE coding, followed by verification.

Use when executing implementation plans with independent tasks in the current session

Use when creating or developing anything, before writing code or implementation plans - refines rough ideas into fully-formed designs through structured Socratic questioning, alternative exploration, and incremental validation

Vision and multimodal capabilities for Claude including image analysis, PDF processing, and document understanding. Activate for image input, base64 encoding, multiple images, and visual analysis.

Testing patterns including pytest, unittest, mocking, fixtures, and test-driven development with extended thinking integration. Activate for test writing, coverage analysis, TDD, hypothesis-driven development, and quality assurance tasks.

Patterns for persisting and retrieving application data. Use when implementing data persistence, caching, or session management.

Comprehensive repository initialization and scaffolding for new projects. Use when setting up a new repository from scratch with git, GitHub, CI/CD workflows, branch protection, validation checks (format, lint, type-check, tests, builds), git hooks (husky/lefthook), GitHub Actions for PR and main branch validation, automated versioning and tagging, and project-specific release workflows. Ideal for solo developers who want production-ready repository setup including (1) Git initialization with main branch, (2) GitHub repository creation and configuration, (3) Branch protection rules, (4) PR workflow with squash merging and auto-delete branches, (5) Comprehensive validation checks, (6) Git hooks for pre-commit and pre-push validation, (7) GitHub Actions CI/CD pipelines, (8) Automated releases with GitHub Releases integration.

Maintain consistent code formatting, naming conventions, type safety, and automated code quality standards across PHP and TypeScript/JavaScript. Use this skill when writing or editing any PHP files (.php), TypeScript/JavaScript files (.ts, .tsx, .js, .jsx), when implementing type declarations and return types, when running code formatters (Laravel Pint, Ultracite) or linters, when running static analysis tools (Larastan), when naming variables, functions, classes, or files, when applying DRY principles, when removing dead code, or when preparing code for review or commit.

Playwright best practices including selectors, wait strategies, accessibility testing, responsive design, and flaky-test prevention. Use when writing or improving Playwright E2E tests.

Test coverage tracking and improvement strategies. Use when analyzing test coverage.

Guide for creating effective skills. Use this skill when you want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Data pipelines, ETL/ELT systems, workflow orchestration, and data modeling

Technical specification writing for implementation details. Use when documenting how to build a solution (post-decision), API contracts, schemas, and system design. Complements RFC skill which handles decision-making.

生成AIが人間に対して行う作業開始時オンボーディング。AIが"説明係"ではなく"進行役"として、探索→仮説→検証→要約→未確定の明示を回し、人間が最小スキーマ（因果・境界・不変条件・壊れ方・観測）を短時間で再構築できる状態に導く。トリガー条件:- 新しいタスクやコード変更に着手する前（「この機能を修正して」「このバグを直して」）- 未知のコードベースを理解する必要がある時- 「オンボーディングして」「作業開始の準備をして」「コードを理解したい」- 複雑なタスクを始める前の文脈理解が必要な時- 「作戦ブリーフを作成して」「安全に始められるようにして」
