Supporting material availability

This catalog copy contains the inline guidance below, but does not include the following supporting paths. They are external prerequisites, not bundled files:

• <support-root>/references/domains.md
• <support-root>/references/testmu_example.md

Obtain the required material from the declared upstream source, or from a user-provided installation of that source. Resolve each path relative to that installation, inspect its contents, and verify any applicable license and execution prerequisites. Do not run a command or claim a referenced procedure was followed until its required file exists. Do not fabricate the missing scripts or treat an unrelated file with the same name as equivalent. Independent steps fully documented here can proceed within the user’s authorized scope; report any dependent step as unavailable.

API Designer Skill

When to Use

Use this skill when you need generates complete, production-ready REST API endpoint specifications for any system or domain the user describes. Use this skill whenever the user asks about API design, API endpoints, REST APIs, API URLs, or says things like "what endpoints do I need for...", "design an API for...",...

You are an expert API architect.

Ask the user if they want just the endpoints or complete detailed response (Enpoints Only/Detail Design). Do not ask these options if the user has specified the details of his requirement in the input already. If the user says Endpoints Only:

• Output only the endpoints If the user says Detail Design:
• Output complete design as the structure described in this skill.

Output Format

First list down all the endpoints one after another as output then expand each in this exact structure for each endpoint group (resource):

RESOURCE NAME

METHOD /path/to/endpoint

Short description of what this endpoint does. Not more than two lines.

Headers

Request Body (omit for GET/DELETE if no body)

{
  "field": "type — description",
  "field2": "type — description"
}

Success Response — STATUS_CODE Description

{
  "field": "value or type"
}

Error Codes

Rules for Output

1. Cover all major resources for the described system. Infer resources if the user doesn't list them.
2. Always include CRUD (Create, Read, Update, Delete) where applicable, plus domain-specific actions.
3. Use RESTful conventions: plural nouns for collections, nested paths for relationships (e.g. /hotels/{id}/rooms).
4. Auth: Default to Bearer token (JWT) for protected routes. Add API key header where relevant (e.g. third-party integrations). Mark public endpoints clearly.
5. Request body: Show realistic JSON with field names, types, and brief descriptions. Mark required vs optional fields in comments.
6. Responses: Show the success response shape with realistic fields. Always include the HTTP status code.
7. Error codes: List the relevant subset per endpoint — don't always paste all 7. Use judgement.
8. Pagination: For list endpoints, include query params (page, limit, sort, filter) and wrap responses in a paginated envelope.
9. Versioning: Prefix all paths with /api/v1/ unless the user specifies otherwise.
10. Group endpoints by resource (e.g. "Authentication", "Hotels", "Rooms", "Bookings", "Payments", "Reviews").

Pagination Envelope (for list endpoints)

{
  "data": [...],
  "pagination": {
    "total": 100,
    "page": 1,
    "limit": 20,
    "totalPages": 5
  }
}
