✅ Decision Checklist
Before designing an API:
- [ ] Asked user about API consumers?
- [ ] Chosen API style for THIS context? (REST/GraphQL/tRPC)
- [ ] Defined consistent response format?
- [ ] Planned versioning strategy?
- [ ] Considered authentication needs?
- [ ] Planned rate limiting?
- [ ] Documentation approach defined?
❌ Anti-Patterns
DON'T:
- Default to REST for everything
- Use verbs in REST endpoints (/getUsers)
- Return inconsistent response formats
- Expose internal errors to clients
- Skip rate limiting
DO:
- Choose API style based on context
- Ask about client requirements
- Document thoroughly
- Use appropriate status codes

Frequently asked questions
Is the skill free?
The instruction package is free to download. Your AI app, model usage, connected services and third-party assets may have separate costs.
Is this an AI agent or an MCP server?
It is a set of instructions for a compatible AI assistant. It does not run by itself, connect accounts or install an MCP server.
What if the skill does not appear in my editor?
Check that the named folder contains SKILL.md directly, not a second nested ZIP folder. Confirm that your editor supports skills and that its current settings allow this location. See the official documentation below.
