comfyui-mcp/dist/handshake-instructions.js

Local-first, agent-native control plane for ComfyUI — MCP server + autonomous sidebar agent that drives your live graph in natural language on ANY LLM: Claude/ChatGPT/Gemini on your subscription (no API key), free local models via Ollama (fully offline),

/**
 * #1747 — server-level MCP `instructions`, read once at initialize.
 *
 * Cross-cutting knowledge (call order, which calls return a handle to poll,
 * pre-flight, trust posture toward canvas/workflow/model-card text) belongs to
 * no single tool. Tool descriptions are the wrong home: they drift, they bloat
 * every schema, and they are byte-pinned by the vocabulary ratchet. This is the
 * one place that knowledge can live.
 *
 * Two surfaces, two audiences:
 *  - `STDIO_HANDSHAKE_INSTRUCTIONS` — the `comfyui-mcp` server in `boot.ts`
 *    (stdio and HTTP). This is what a Claude Code / LiteLLM / compact-mode
 *    client actually reads.
 *  - `PANEL_HANDSHAKE_INSTRUCTIONS` — the `comfyui-panel` HTTP server. Live
 *    canvas only; it must not recap the stdio catalog.
 *
 * The introspect probe and the in-process `call_tool` child are not agent
 * handshakes and stay empty.
 *
 * Size is a budget. The ceilings below are the ratchet; the tests measure utf8
 * bytes so growth is a reviewed edit rather than unnoticed prose.
