## What it does

The skill wraps `tools/image_edit.py`, which calls cloud deployments on Modal or RunPod. Default model is Qwen-Image-Edit-2511 under Apache-2.0; you can deploy Qwen-Image-2.1 on Modal, but it comes with a non-commercial Qwen Research License. After each edit the script prints the model and step count.

Three files carry the knowledge: `prompting.md` for prompt structure, `examples.md` with good and bad cases from experiments, `parameters.md` for steps, guidance and negative prompts. The measurements were done on 2511, so re-check exact numbers before relying on them with 2.1.

Single-image background replacement tends to produce halos and cut-out artifacts. Face swapping does not hold identity from a reference, and outpainting cannot extend the canvas reliably. Multi-image compositing can work if you describe distinctive features and push guidance to about 2.0. So this skill fits portraits, style transfers and local edits — not face swaps.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add digitalsamba/claude-code-video-toolkit --skill qwen-edit -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/qwen-edit/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/qwen-edit/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add digitalsamba/claude-code-video-toolkit --skill qwen-edit -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/qwen-edit/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add digitalsamba/claude-code-video-toolkit --skill qwen-edit -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/qwen-edit/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install digitalsamba/claude-code-video-toolkit qwen-edit
```

2. **Manually: put the files in place**
- File: `.github/skills/qwen-edit/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add digitalsamba/claude-code-video-toolkit --skill qwen-edit -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/digitalsamba/claude-code-video-toolkit --path .claude/skills/qwen-edit
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/qwen-edit/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add digitalsamba/claude-code-video-toolkit --skill qwen-edit -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/digitalsamba/claude-code-video-toolkit/tree/HEAD/.claude/skills/qwen-edit/SKILL.md

## When to use it
- preserve identity while changing pose or clothing
- reframe a cropped photo with a cut-off head
- apply a cyberpunk or oil painting style
- cut out a subject onto a transparent background
- compose one image from several reference photos

## Example prompts
- edit photo.jpg and add sunglasses
- reframe this image as a portrait with the full head visible, negative prompt 'blur, distortion, artifacts'
- put the person from person.jpg into the scene from background.jpg, keep the same face and hair

# Qwen-Image-Edit Skill

AI-powered image editing via `tools/image_edit.py`. The model depends on the deployment:

| Deployment | Model | License | Defaults | Max inputs |
|-----------|-------|---------|----------|------------|
| `--cloud modal` (default) | Qwen-Image-Edit-2511 | Apache-2.0, commercial OK | 8 steps, guidance 1.0 | 3 images |
| `--cloud modal`, app deployed with `IMAGE_EDIT_MODEL=qwen-image-2.1` | **Qwen-Image-2.1** (2026-09, unified gen+edit, 7B DiT, RGBA) | Qwen Research License -- **non-commercial** ("research or evaluation purposes only") | 40 steps, guidance 1.0 (no CFG) | 10 images |
| `--cloud runpod` | Qwen-Image-Edit-2511 + Lightning LoRA | Apache-2.0, commercial OK | 8 steps, guidance 1.0 | 3 images |

The tool prints `Model:` and `Steps:` after each edit, so you can tell which model the Modal app
runs and how many steps it took. Without `--steps`, each model runs its own default above.
Opt in with `IMAGE_EDIT_MODEL=qwen-image-2.1 uv run modal deploy docker/modal-image-edit/app.py`;
deploy again without it to switch back.

**Status:** Evolving - learnings being captured as we experiment. The prompt
patterns and parameter findings in `examples.md` / `parameters.md` were measured
on 2511; re-check them on 2.1 before relying on the exact numbers.

### Qwen-Image-2.1 specifics (Modal opt-in)

- **Not step-distilled** -- 40 steps is the model card default. The old 8-step
  default was tuned for 2511's Lightning LoRA, which 2.1 doesn't have here, so expect
  low step counts to cost quality (untested).
- **Sampled without guidance.** `--guidance 1.0` (default) is how the model is meant
  to run. `>1` switches on true CFG (blank negative prompt if you pass none) and
  doubles the cost of every step.
- **Multi-image:** the first `--input` is the image being edited ("image 1"); the
  rest are references in order ("image 2", ...). Up to 10. Output size follows the
  first image's aspect ratio at ~1MP.
- **Local edits:** draw a circle or paint an annotation on the image, or pass a
  separate mask as an extra `--input`, and say what to change there
  (e.g. "Remove the watch inside the red circle").
- **RGBA:** transparent PNG inputs keep their alpha. For a cut-out, prompt
```
