Design and build reusable UI components following Astro's server-first architecture with islands, proper component composition, TypeScript props, and strategic client-side hydration. Use this skill when creating or modifying Astro components, React/Vue/Svelte islands, layout components, or any reusable UI elements. When working on .astro component files, framework component files (.jsx, .tsx, .vue, .svelte), layout components, page components, component prop interfaces, slot implementations, client directive usage (client:load, client:idle, client:visible), scoped component styles, or component documentation and examples.

Improves the quality of images, especially screenshots, by enhancing resolution, sharpness, and clarity. Perfect for preparing images for presentations, documentation, or social media posts.

Provides SVC naming conventions, comment style, code structure order, and reset patterns. Triggers when writing or modifying any .sv file.

High-performance JSON and CSV parsing library for Clojure. Use when working with JSON or CSV data and need fast in Clojure, efficient parsing/writing with a clojure.data.json/clojure.data.csv compatible API.

Follow development best practices including consistent project structure, clear documentation with README files, version control best practices with clear commit messages, environment configuration using environment variables, minimal dependency management, code review processes, testing requirements, feature flags for incomplete features, and changelog maintenance. Use this skill when organizing project files and directories, writing commit messages, managing dependencies, setting up environment configurations, establishing code review processes, or maintaining project documentation. This skill applies when working on project organization, git workflows, dependency management, or any project-level conventions.

Hono + Zod OpenAPIを使用したAPIエンドポイント作成を支援。(1)新しいAPIエンドポイント追加、(2)ルート定義作成、(3)レスポンススキーマ定義、(4)エンティティスキーマ作成で使用。トリガー：「APIを作成」「エンドポイント追加」「ルート追加」「GET/POST/PUT/DELETE API」「スキーマ定義」「レスポンス型」

Fallback formatter that extracts tasks from any document structure using best-effort pattern matching. Use when user says 'format unknown document', 'extract tasks from any document', 'process mixed content', 'handle custom format', or when detect-input-type returns 'generic'. Handles ADRs, custom docs, and novel structures in .md files. (plugin:task-streams)

Comprehensive guide to Python async/await patterns, best practices, and anti-patterns. Covers asyncio fundamentals, coroutines, async context managers, task management, common libraries (aiohttp, aiofiles, asyncpg), framework integration (FastAPI, Django), performance considerations, and proper exception handling. Use when reviewing or writing asynchronous Python code.

Convert OSCAL documents between formats (JSON, YAML, XML) and to human-readable formats like Markdown or plain text. Use for document transformation, reporting, and making OSCAL data accessible to non-technical stakeholders.

Access pattern library extracted from existing templates for reuse when creating new templates. Use when creating .md files for commands, agents, skills or when generating CLAUDE.md, README.md, or settings.json. Provides templatable patterns and quick-start presets.

Systematic methodology for debugging bugs, test failures, and unexpected behavior.Use when encountering any technical issue before proposing fixes. Covers root causeinvestigation, pattern analysis, hypothesis testing, and fix implementation.Use ESPECIALLY when under time pressure, "just one quick fix" seems obvious, oryou've already tried multiple fixes. NOT for exploratory code reading.

Comprehensive pre-production repository audit for preparing repos for public release. Use when the user wants to perform a "final sweep", "production check", "pre-release audit", or prepare a repository to be made public. Audits metadata files across all project types (Fabric mods, Node/npm, Go, Python, etc.) for correct username/organization, checks README links, and identifies leftover development artifacts like planning docs, test scripts, and temporary files. Interactive cleanup with user confirmation.

Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies

Discovers and lists recently modified or created files in Google Drive with professional metadata and summaries. Returns a structured table including file names, types (Docs, Sheets, PDFs, etc.), modification timestamps, 30-word summaries, owners, and direct Drive links. Defaults to the last 24 hours but accepts custom timeframes (e.g., "last 3 hours" or "last week"). Sorts by most recent activity and highlights key changes like new folders, shared file updates, and SNMG18 Meeting Minutes modifications. Use for tracking file changes, finding recent work, or monitoring Drive activity.

Plan and execute complex features using markdown checklists. Use when the user asks to "plan a feature", "create a checklist", or "break down a task".

Generate detailed implementation plans for complex tasks. Creates comprehensive strategic plans in Markdown format with objectives, step-by-step implementation tasks using checkbox format, verification criteria, risk assessments, and alternative approaches. All plans MUST be validated using the included validation script. Use when users need thorough analysis and structured planning before implementation, when breaking down complex features into actionable steps, or when they explicitly ask for a plan, roadmap, or strategy. Strictly planning-focused with no code modifications.

Automated generation of promotional assets for podcast episodes from transcripts. Use when the user provides a podcast episode transcript (markdown file) and needs: (1) a one-paragraph episode summary, (2) AI-generated featured image, (3) compelling quotes for social media, (4) short promotional video. Orchestrates transcript analysis, AI image generation via Replicate MCP, and video creation for complete episode marketing asset package.

Generate type-safe API clients from OpenAPI/Swagger specifications or API documentation. Use when users need to create TypeScript or Python API clients with Zod/Pydantic validation, retry logic, error handling, and proper typing. Supports REST APIs, generates from OpenAPI specs or manual endpoint definitions.

Maintains SnowTower project documentation, README, and Claude configuration. Use when updating documentation, auditing .claude folder contents, syncing README with actual project state, or reviewing agent/pattern definitions. Triggers on mentions of documentation, README, maintenance, or .claude folder updates.

Write secure, performant database queries using parameterization, proper indexing, and optimization techniques. When creating or modifying database query logic, data access layers, or repository files. When working on files that interact with databases using SQL, ORMs, or query builders. When implementing SELECT queries, joins, transactions, or data fetching logic. When optimizing queries to prevent N+1 problems, using eager loading, or implementing query caching. When writing parameterized queries to prevent SQL injection vulnerabilities.
