Use this skill when you writing commands, hooks, skills for Agent, or prompts for sub agents or any other LLM interaction, including optimizing prompts, improving LLM outputs, or designing production prompt templates.
WHAT YOU BECOME
Perfect for these scenarios
Write failing test for bug, then implement fix to ensure resolution
Define tests first, then build minimal code to meet requirements
Ensure existing behavior stays intact during code restructuring
Verify API responses match expectations before implementation
MEASURED GAIN
Proven benefits and measurable impact
Catch issues early by writing tests before implementation
Isolate failures quickly with pre-written test cases
Focus on minimal, test-driven implementations for better maintainability
WHAT YOU GET
Files, tags and the three-step install
Tip: Read the documentation and the code before first use, so you know what it does and which permissions it needs.

Claude Code agent generation system that creates custom agents and sub-agents with enhanced YAML frontmatter, tool access patterns, and MCP integration support following proven production patterns
Generate and maintain AGENTS.md files following the public agents.md convention. Use when creating documentation for AI agent workflows, onboarding guides, or when standardizing agent interaction patterns across projects.
Validate OpenAPI, Swagger, and GraphQL schemas match backend implementation. Detect breaking changes, generate TypeScript clients, and ensure API documentation stays synchronized. Use when working with API spec files (.yaml, .json, .graphql), reviewing API changes, generating frontend types, or validating endpoint implementations.
