Implements React Flow node-based UIs correctly using @xyflow/react. Use when building flow charts, diagrams, visual editors, or node-based applications with React. Covers nodes, edges, handles, custom components, state management, and viewport control.

Guides you through comprehensive iOS/Swift app planning and analysis. Use for new apps (concept to architecture) or existing apps (audit current state, plan improvements, evaluate tech stack). Covers product planning, technical decisions, UI/UX design, and distribution strategy.

ドキュメントとコードの乖離を監査。APIエンドポイント、スキーマ、設定ファイルとドキュメントを比較し、不整合をレポート。定期的なドキュメントヘルスチェックに使用。

Enforces TheOne Studio React Native development standards including TypeScript patterns, React/Hooks best practices, React Native architecture (Zustand/Jotai, Expo Router), and mobile performance optimization. Triggers when writing, reviewing, or refactoring React Native code, implementing mobile features, working with state management/navigation, or reviewing pull requests.

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

Expert in test-first development of production-quality OpenRewrite recipes for automated code refactoring. Automatically activates when working with OpenRewrite recipe files, Java/YAML files in `src/main/java/**/rewrite/**` directories, writing tests implementing `RewriteTest`, or when users ask about recipe development, writing recipes, creating migrations, LST manipulation, JavaTemplate usage, visitor patterns, preconditions, scanning recipes, YAML recipes, GitHub Actions transformations, Kubernetes manifest updates, or code migration strategies. Guides recipe type selection (declarative/Refaster/imperative), visitor implementation, and test-driven development workflows.

Create and manage Jupyter notebooks for testing Adobe Edge Delivery Services (EDS) blocks interactively in the browser using the ipynb-viewer block. Interactive JavaScript execution, overlay previews with backdrop, direct ES6 imports. Use when creating notebooks, testing blocks with ipynb files in browser, generating overlay previews, or creating executable documentation.

Technical leadership guidance for engineering teams, architecture decisions, and technology strategy. Includes tech debt analyzer, team scaling calculator, engineering metrics frameworks, technology evaluation tools, and ADR templates. Use when assessing technical debt, scaling engineering teams, evaluating technologies, making architecture decisions, establishing engineering metrics, or when user mentions CTO, tech debt, technical debt, team scaling, architecture decisions, technology evaluation, engineering metrics, DORA metrics, or technology strategy.

Creates effective SKILL.md files with proper YAML frontmatter, trigger keywords, and best practices. Use when creating skills, writing skill descriptions, authoring SKILL.md files, or learning skill format.

Create or update presentation notebooks with embedded HTML and JavaScript in markdown cells using EDS blocks. Convert executable code cells to informative text. Build presentations, slides, demos, showcases with accordion, cards, tabs, hero, grid, table blocks. No runnable JavaScript cells - only visual markdown with inline scripts for presentation mode.

Creates bauplan data pipeline projects with SQL and Python models. Use when starting a new pipeline, defining DAG transformations, writing models, or setting up bauplan project structure from scratch.

Refreshes README.md documentation tables including the packages table and core namespace index. Reads from package.json files and core module JSDoc.

Extracts web content and performs reliable searches when standard tools fail due to access restrictions, rate limiting, or validation errors. Use when encountering 403/429/422 errors, blocked documentation sites, or silent search failures. **Direct tool execution often fails for these scenarios - search-plus agent delegation provides the most reliable results.**

Research web content, documentation, and best practices using the gemini-search agent for token-efficient searches with caching. Use when you need to fetch documentation, research best practices, or gather information from the web.

Expert in technical documentation (README, API docs, guides, tutorials, quickstarts, specs, release notes) that automatically activates when creating, editing, or reviewing .md files in docs/ directories, README files, or when discussing documentation structure, style guides, or content organization. Follows industry best practices for clear, accessible technical communication across all documentation types.

Master TypeScript type-level programming with conditional types, mapped types, template literals, and infer patterns. Use when writing advanced types, creating utility types, or solving complex type challenges.

Protocol fuzzer script development using boofuzz framework. Use when creating network protocol fuzzers, defining protocol PDUs (Protocol Data Units), writing mutation-based fuzzing scripts, or contributing to the boofuzz project. Covers binary protocol definitions, session management, crash detection, and reporting findings.

Comprehensive skill for Ruby RBS type signatures. Use for writing inline type annotations in Ruby files, creating standalone .rbs signature files, scaffolding types, or setting up Steep type checking. Covers both inline syntax (rbs-inline) and standalone RBS file format.

Vitest testing framework patterns and best practices. Use when writing unit tests, integration tests, configuring vitest.config, mocking with vi.mock/vi.fn, using snapshots, or setting up test coverage. Triggers on describe, it, expect, vi.mock, vi.fn, beforeEach, afterEach, vitest.
