Assists in writing high-quality content by conducting research, adding citations, improving hooks, iterating on outlines, and providing real-time feedback on each section. Transforms your writing process from solo effort to collaborative partnership.

Automated testing workflow for backend and frontend. Use when writing tests, fixing test failures, or validating code changes. Runs pytest for backend and jest/vitest for frontend.

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

Verify claims against referenced sources. Checks if blog content accurately represents external resources, APIs, or documentation.Trigger phrases: "fact check", "verify", "check claims", "verify claims", "check sources", "verify sources"

PolicyEngine code writing style guide - formula optimization, direct returns, eliminating unnecessary variables

Guide for writing unit tests with Vitest for Fastify plugins and routes. Use when creating or modifying tests in app/tests/.

Master ES6+ features including async/await, destructuring, spread operators, arrow functions, promises, modules, iterators, generators, and functional programming patterns for writing clean, efficient JavaScript code. Use when refactoring legacy code, implementing modern patterns, or optimizing JavaScript applications.

Seurat documentation (local mirror)

Interactive ClaudeShack ecosystem initialization that analyzes your codebase, mines history, discusses findings with you to establish baseline understanding, and seeds Oracle with verified knowledge. Use when setting up ClaudeShack in a new project or resetting knowledge. Creates a personalized foundation that improves over use. Sets up Context7 for current library docs.

Generate production-ready React/TypeScript components from detailed specifications with complete tests, styles, and documentation

Create comprehensive implementation plans for engineers with minimal codebase knowledge. This skill should be used when breaking down features into detailed, step-by-step implementation guides following TDD principles.

Multi-phase research orchestration for thorough codebase, documentation, and external knowledge investigation. Invoked by /ai-eng/research command. Use when conducting deep analysis, exploring codebases, investigating patterns, or synthesizing findings from multiple sources.

Create and edit markdown-based presentations using Slidev framework. Use when the user asks to create slides, presentations, or decks, or when working with .slides.md files. Supports mise/bun workflow, GitHub Pages publishing, and multi-deck landing pages.

This skill should be used when evaluating the quality of book chapters, lessons, or educational content. It provides a systematic 6-category rubric with weighted scoring (Technical Accuracy 30%, Pedagogical Effectiveness 25%, Writing Quality 20%, Structure & Organization 15%, AI-First Teaching 10%, Constitution Compliance Pass/Fail) and multi-tier assessment (Excellent/Good/Needs Work/Insufficient). Use this during iterative drafting, after content completion, on-demand review requests, or before validation phases.

Generate professional product mascot character reference sheets with a specific multi-panel layout. Use this skill when creating character design sheets, mascot documentation, brand mascot references, or character consistency guides with multiple views (isometric, front/back/left/right, emotion poses). Optimized for product mascots and brand characters using Gemini image generation with Libre Baskerville typography.

Implement robust error handling with user-friendly messages, fail-fast validation, specific exception types, centralized error boundaries, graceful degradation, retry strategies, and proper resource cleanup. Use this skill when writing try-catch blocks or exception handling code in any programming language (JavaScript/TypeScript, Python, Java, Go, Rust), implementing error boundaries in React (ErrorBoundary components) or similar error handling patterns in other frameworks (Vue error handlers, Angular ErrorHandler), handling API errors and HTTP error responses in fetch calls, Axios requests, or tRPC procedures, validating user input and function preconditions at the start of functions, creating custom error classes or exception types for specific failure scenarios (ValidationError, NotFoundError, UnauthorizedError, PaymentError), implementing retry logic with exponential backoff for external service calls, network requests, or database queries, ensuring proper resource cleanup in finally blocks or using langu

Create reversible, focused database migrations with proper naming, version control practices, and zero-downtime deployment considerations. Use this skill when creating or editing migration files in database/migrations/, when writing schema changes (creating/modifying tables, columns, indexes, foreign keys), when implementing migration rollback methods, when managing database version control, when adding or modifying indexes on large tables, or when separating schema changes from data migrations for safer deployments.

Use when writing pytest tests, creating fixtures, mocking dependencies, or testing async code - provides patterns that verify actual behavior with proper fixtures and parametrization; prevents testing mocks instead of code (plugin:python@dot-claude)

Create a new blog post. Use when user says "new post", "新文章", "新增文章", or wants to start writing a new article.

Transform stakeholder needs into structured, testable specifications with user stories, acceptance criteria, and business rules. Use when: (1) creating requirements documents, (2) writing user stories with acceptance criteria, (3) defining business rules and process flows, (4) analyzing feature requests.
