-## Search, Inspect, Run
+## Discover all models
+
+MCP Search presents text, image and video models in one capability catalog.
+They retain different execution lifecycles after discovery:
+
+| Model type | Discovery | Execution |
+| --- | --- | --- |
+| Text / LLM | MCP Search → Inspect; REST fallback: authenticated `GET /v1/models` | Direct synchronous `/v1/responses` or compatibility interface |
+| Image / video | MCP Search → Inspect; REST inventory: `GET /v1/media/models` | Asynchronous `capabilities_run` or documented model task endpoint |
+
+When MCP is configured, paginate `capabilities_search` with `kind: "model"` for
+the combined inventory. Without MCP, the complete model inventory is the union
+of `/v1/models` and `/v1/media/models`. Preserve model types and execution
+lifecycles; do not present the union as one interchangeable protocol. Never
+infer key access from a marketing page or cached model name.
+
+## Text models: Search, Inspect, call
+
+Use this route when the user explicitly asks to use BeatAPI for text, reasoning,
+coding, analysis, chat, or another language-model task. Do not route ordinary
+conversation to a paid model without that explicit BeatAPI intent.
+
+1. With MCP, call `capabilities_search` using `kind: "model"` and a short model
+   family or provider query such as `deepseek` or `glm`. Text results have the
+   category `text` and a `model:<id>` reference. Without MCP, call authenticated
+   `GET https://api.beatapi.io/v1/models`; its OpenAI-compatible response is
+   `{ "object": "list", "data": [...] }`.
+2. Choose only an ID returned by live discovery. Match the user's requested
+   model when present; otherwise select using the task, required context,
+   latency, quality and cost constraints.
+3. With MCP, Inspect the selected `model:<id>`. A text contract declares
+   execution strategy: `direct_api` and run_supported: `false`, and provides the
+   endpoint, authentication, input schema, compatibility routes and example.
+4. Prefer `POST https://api.beatapi.io/v1/responses` for new integrations.
+   Send `model`, `input`, and `stream: false` unless the host explicitly supports
+   streaming. Use `/v1/chat/completions` only for an existing OpenAI Chat
+   Completions integration.
+5. Read the synchronous response and return the requested result. Do not call
+   `capabilities_run` or poll a media task for a text response.
+
+Example request body for the Responses interface:
+
+```json
+{
+  "model": "<id returned by GET /v1/models>",
+  "input": "<the user's requested task>",
+  "stream": false
+}
+```
+
+Never execute placeholders literally or substitute a model name remembered
+from this Skill, a marketing page, or an earlier session. A `401` means the key
+was not accepted; a `404` means the text interface is not enabled in that
+environment. A `402` means the account lacks sufficient balance. Report the
+error and request ID without exposing credentials.
+
+## Search, Inspect, execute
+
+Use Search and Inspect for every capability type. After Inspect, follow its
+execution strategy. `capabilities_run` is optional: it is used only when the
+selected contract says `run_supported: true`.
