ComfyUI — Local Image Generation

Run FLUX.2 image-generation workflows on a local ComfyUI server via its REST API.

Server: http://localhost:8188

Critical Rules for Agents

1. Always verify the server is running before queuing work: curl -s http://localhost:8188/system_stats | head -c 200.
2. Randomize seeds for each generation unless the user asks for reproducibility. Generate a random integer (up to 2^53 - 1).
3. Poll for completion — the /prompt endpoint returns immediately with a prompt_id; you must poll /history/{prompt_id} until outputs appear.
4. Download results to the current working directory so the user can see them.
