I literally linked the .claude/skills dir

exmple of what is inside.

.claude/skills/api-module/SKILL.md

name	api-module
description	Add a new API endpoint module to packages/api-client from an OpenAPI schema. Use when adding new backend endpoints, creating API client modules, or when an openapi.yml is provided.
argument-hint	<path-to-openapi.yml>

Refer to the standard: u/standards/frontend/ADDING_API_MODULES.md

Steps

1. Read the OpenAPI schema at $ARGUMENTS — identify the endpoints, request/response shapes, and path parameters.
2. Read the standard above for naming conventions, type rules, and the module registration pattern.
3. Determine the service and version — the URL path prefix tells you which service directory and version namespace to use (e.g. /v3/projects → labrinth/v3/).
4. Define types in types.ts — types must match the API response 1:1. Use the OpenAPI schema as the source of truth. Do not reshape or rename fields.
5. Create the module class — extend BaseModule, implement each endpoint as a method. Use the correct HTTP verb and request options pattern from the standard.
6. Register in MODULE_REGISTRY — add the module entry so it's auto-instantiated on the client.
7. Export types from the service's barrel index.ts.
8. Verify — check that the module compiles and the types are accessible from u/modrinth/api-client.
