mixins

Vovk.ts OpenAPI mixins — importing third-party OpenAPI 3.x schemas as typed client modules that share the same call signature as native Vovk RPC modules. Use whenever the user asks to "call a third-party API from my Vovk app", "mixin an OpenAPI schema", "import an OpenAPI spec as a client", "wrap an external service that only ships an OpenAPI doc", or mentions `openAPIMixin`, `getModuleName`, `getMethodName`, `withDefaults` on a generated API module, or the `Mixins` namespace. Also use to push back when the user reaches for mixins for a vendor with a great official SDK (Stripe, AWS, GitHub via Octokit) — the skill explains when the official client is the better choice. Covers remote/local/inline specs, module + method naming strategies, `apiRoot`, per-mixin fetcher, AJV client validation knobs, and composed/segmented clients. **`deriveTools` works with mixins for OpenAI / Anthropic / Vercel function-calling** (reads `parameters` JSON Schema), but the `mcp-handler` path needs `inputSchemas` Standard Schemas which mixins don't carry — wrap in `createTool({...})` for MCP (see `tools` skill).
