# ComfyUI

Generate images, video, audio, and 3D content through ComfyUI using the
official `comfy-cli` for setup/lifecycle and direct REST/WebSocket API
for workflow execution.

## What's in this skill

**Reference docs (`references/`):**

- `official-cli.md` — every `comfy ...` command, with flags
- `rest-api.md` — REST + WebSocket endpoints (local + cloud), payload schemas
- `workflow-format.md` — API-format JSON, common node types, param mapping
- `template-integrity.md` — converting `comfyui-workflow-templates` from
  editor format to API format: Reroute bypass, dotted dynamic-input keys
  (`values.a`, `resize_type.width`), Cloud quirks (302 redirect, 1 concurrent
  free-tier job, 1080p VRAM ceiling), Discord-compatible ffmpeg stitch.

  you're starting from an official template.

**Scripts (`scripts/`):**

| Script | Purpose |
|--------|---------|
| `_common.py` | Shared HTTP, cloud routing, node catalogs (don't run directly) |
| `hardware_check.py` | Probe GPU/VRAM/disk → recommend local vs Comfy Cloud |
| `comfyui_setup.sh` | Hardware check + comfy-cli + ComfyUI install + launch + verify |
| `extract_schema.py` | Read a workflow → list controllable params + model deps |
| `check_deps.py` | Check workflow against running server → list missing nodes/models |
| `auto_fix_deps.py` | Run check_deps then `comfy node install` / `comfy model download` |
| `run_workflow.py` | Inject params, submit, monitor, download outputs (HTTP or WS) |
| `run_batch.py` | Submit a workflow N times with sweeps, parallel up to your tier |
| `ws_monitor.py` | Real-time WebSocket viewer for executing jobs (live progress) |
| `health_check.py` | Verification checklist runner — comfy-cli + server + models + smoke test |
| `fetch_logs.py` | Pull traceback / status messages for a given prompt_id |

**Example workflows (`workflows/`):** SD 1.5, SDXL, Flux Dev, SDXL img2img,
SDXL inpaint, ESRGAN upscale, AnimateDiff video, Wan T2V. See
`workflows/README.md`.

## When to Use

- User asks to generate images with Stable Diffusion, SDXL, Flux, SD3, etc.
- User wants to run a specific ComfyUI workflow file
- User wants to chain generative steps (txt2img → upscale → face restore)
- User needs ControlNet, inpainting, img2img, or other advanced pipelines
- User asks to manage ComfyUI queue, check models, or install custom nodes
- User wants video/audio/3D generation via AnimateDiff, Hunyuan, Wan, AudioCraft, etc.

## Architecture: Two Layers

```
┌─────────────────────────────────────────────────────┐
│ Layer 1: comfy-cli (official lifecycle tool)        │
│   Setup, server lifecycle, custom nodes, models     │
│   → comfy install / launch / stop / node / model    │
└─────────────────────────┬───────────────────────────┘
                          │
┌─────────────────────────▼───────────────────────────┐
│ Layer 2: REST/WebSocket API + skill scripts         │
│   Workflow execution, param injection, monitoring   │
│   POST /api/prompt, GET /api/view, WS /ws           │
│   → run_workflow.py, run_batch.py, ws_monitor.py    │
└─────────────────────────────────────────────────────┘
```

**Why two layers?** The official CLI is excellent for installation and server
management but has minimal workflow execution support. The REST/WS API fills
that gap — the scripts handle param injection, execution monitoring, and
output download that the CLI doesn't do.

## Quick Start

### Detect environment

```bash
# What's available?
command -v comfy >/dev/null 2>&1 && echo "comfy-cli: installed"
curl -s http://127.0.0.1:8188/system_stats 2>/dev/null && echo "server: running"

# Can this machine run ComfyUI locally? (GPU/VRAM/disk check)
python3 scripts/hardware_check.py
```

If nothing is installed, see **Setup & Onboarding** below — but always run the
hardware check first.

### One-line health check

```bash
python3 scripts/health_check.py
# → JSON: comfy_cli on PATH? server reachable? at least one checkpoint? smoke-test passes?
```

## Core Workflow

### Step 1: Get a workflow JSON in API format

Workflows must be in API format (each node has `class_type`). They come from:

- ComfyUI web UI → **Workflow → Export (API)** (newer UI) or
  the legacy "Save (API Format)" button (older UI)
- This skill's `workflows/` directory (ready-to-run examples)
- Community downloads (civitai, Reddit, Discord) — usually editor format,
  must be loaded into ComfyUI then re-exported

Editor format (top-level `nodes` and `links` arrays) is **not directly
executable**. The scripts detect this and tell you to re-export.

### Step 2: See what's controllable

```bash
python3 scripts/extract_schema.py workflow_api.json --summary-only
# → {"parameter_count": 12, "has_negative_prompt": true, "has_seed": true, ...}

python3 scripts/extract_schema.py workflow_api.json
# → full schema with parameters, model deps, embedding refs
