Technical Writing

Generate comprehensive codebase documentation using the Diátaxis framework. Creates tutorials (learning-oriented), how-to guides (problem-solving), reference docs (technical descriptions), and explanations (conceptual). Supports monorepos, multiple languages, and session persistence (resume anytime). Use when: (1) documenting a new codebase, (2) updating existing docs after code changes, (3) user mentions "generate docs", "document this code", "write documentation", (4) creating README, API docs, or user guides.

Design test strategy with concrete test cases. Use before writing tests.

Discovery-driven codebase indexer for Claude Code. Analyzes what EXISTS in a project, then documents what developers need to know. Creates CLAUDE.md + claude-docs/ with architecture-aware documentation. Supports any language (JS/TS, Python, Java, Rust, Go, etc.). Use when: user asks to "index project", "document codebase", "set up claude docs", "analyze project structure", "help me understand this codebase", or when starting work on unfamiliar project. Triggers on phrases like "index this", "create docs for claude", "document the codebase", "set up project documentation".

Write secure, performant, and optimized database queries using parameterized queries, eager loading, proper indexing, and transaction management. Use this skill when writing database queries in controllers, repositories, services, or model methods, when using query builders or ORM methods, when implementing filtering/sorting/pagination logic, when optimizing N+1 query problems with eager loading, when working with joins and complex queries, when implementing query caching, or when wrapping related operations in database transactions.

Generate comprehensive async pytest tests for Quart endpoints, database operations, and WebSocket connections. Activates when writing tests or ensuring code coverage.

Documentation standards and patterns

Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first

Python development best practices, patterns, and conventions. Use when writing Python code, reviewing .py files, discussing pytest, asyncio, type hints, pydantic, dataclasses, or Python project structure. Triggers on mentions of Python, pytest, mypy, ruff, black, FastAPI, Django, Flask.

Guide for spec-based agent-driven development using structured requirements (EARS notation), technical design documentation, and implementation planning. Use when users want to build features using a specification-first approach, need to document requirements formally, want to generate implementation plans from specs, or when working on projects that benefit from clear requirement-to-code traceability.

Documentation for Kubernetes Agent Sandbox - a CRD-based system for managing isolated AI agent execution environments. Use for queries about Sandbox CRDs (Sandbox, SandboxTemplate, SandboxClaim, SandboxWarmPool), Python SDK (SandboxClient, SandboxRouter, ComputerUseExtension), network policies, security configurations, and implementation examples. Keywords kubernetes sandbox, agent sandbox, CRD, python sdk, agentic-sandbox-client, isolated environment, gvisor, network policy.

General documentation standards for README, AsciiDoc, and technical documentation

Collaborative idea refinement - turns rough ideas into fully-formed designs through questioning, alternative exploration, and incremental validation. Use before writing code or implementation plans.

Customer-facing documentation

Design and implement RESTful API endpoints following REST principles with proper HTTP methods, status codes, and URL conventions. Use this skill when creating or modifying API routes, route handlers, API endpoint files, controller files that handle HTTP requests and responses, or any server-side files that define RESTful endpoints. Use this when working on API versioning, implementing rate limiting, designing resource-based URLs, handling query parameters for filtering/sorting/pagination, or structuring nested resource endpoints. Use this when writing code in files like routes.js, api.js, controllers/, handlers/, endpoints/, or any file that defines HTTP API routes and responses.

Meta-skill for extracting and creating reusable Claude Code skills from past work sessions. Analyzes git history, code patterns, workflows, and documentation to identify harvestable skills, then generates comprehensive skill definitions with best practices, examples, and structured templates.

Technical documentation creation and improvement with emphasis on clarity, conciseness, and maximum communication efficiency. Use for README files, API docs, project documentation, code comments, and any written content. Prioritizes brevity over verbosity, essential information over comprehensive detail, and immediate usefulness over exhaustive coverage.

AI-powered insights, UX copywriting standards, and user experience guidelines for vehicle insurance platform. Use when designing insight panels, writing user-facing copy, implementing status messages, creating onboarding flows, or improving accessibility. Covers tone standards, interactive patterns, error messages, and empty states.

Complete end-to-end patent application creation from invention disclosure to USPTO-ready filing - prior art search, claims drafting, specification writing, diagrams, compliance checking

Write and debug Bun tests with proper mocking, coverage, and isolation. Use when writing tests, debugging test failures, setting up test infrastructure, mocking fetch/modules, or improving test coverage.

Generates human-style commit messages based on code changes. Use when user needs help writing commit messages or wants suggestions for describing their changes naturally.
