## What it does

The skill walks an agent through Scenario MCP: pick a model, read its schema, run the job, wait for it, then display and download the asset. Inpainting and outpainting are `img2img`, not separate capabilities. `model_schema_get` comes before every `model_run`, because the contract differs from model to model.

Three fields break runs. Sizing has no common shape: numeric `width` and `height` with a `step`, an enum such as `aspectRatio` or `resolution`, or an aspect ratio alone, which puts an exact pixel target out of reach. Prompt length varies too, so a prompt that fits one model returns a 400 on the next. References are described in the schema: a field named `referenceImages` is a single scalar file on some models. Where the schema says `array: true`, pass an array even for one asset, since a bare string is dropped silently and the run succeeds while ignoring the reference.

For an exact size, the skill suggests generating at the nearest reachable size at or above the target, then finishing with `model_scenario-resize-image` using `fit` `cover` or `stretch`. Watch out: `contain`, the default, can return an image smaller than the box. The skill leans on sibling Scenario skills, so if one is missing, ask the user to install it.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-image -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-image -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-image -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install scenario-labs/skills scenario-image
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-image -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/scenario-labs/skills --path skills/scenario-image
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-image -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/scenario-labs/skills/tree/HEAD/skills/scenario-image/SKILL.md

## When to use it
- generate an image from a text prompt
- restyle or edit an existing image
- fill a masked region and extend the frame outward
- pick a model and learn its limits before running
- land exact pixel dimensions for a layout

## Example prompts
- Generate a 210x600 banner with scenario-image and resize it to exact pixels
- Edit this image by mask: drop the background, keep the object
- Recommend an img2img model and show its prompt limits

# Scenario Image Generation and Editing

## Overview

Scenario runs hundreds of image models, split across `txt2img` (generate from a prompt) and
`img2img` (edit, restyle, inpaint, upscale). The loop is the one the `scenario` skill teaches. What
breaks image runs is the per-model contract: sizing fields, prompt limits, and reference caps differ
between two models that do the same job, so read `model_schema_get` every time. Per-family contracts
(sizing families, reference caps, edit modes): `scenario-seedream`, `scenario-gpt-image`,
`scenario-gemini-image`, `scenario-ideogram`, `scenario-reve`, `scenario-luma-image`,
`scenario-mai-image`, `scenario-grok-imagine-image`. Upscaling, grading, effects, expand, resize and
the other tool models: see `scenario-image-editing`. Holding one look across a set: see
`scenario-consistency`. One image from several references, each with one job:
`scenario-multi-reference`. Sprites, icons, and tilesets: see `scenario-game-assets`. If a sibling
skill named here is missing from your available skills, ask the user to install it
(`npx skills add scenario-labs/skills --skill <name>`); unattended, proceed from tool schemas and
flag the gap.

| Pick a model      | `recommend` with `capability="txt2img"` or `"img2img"`, or `search` (`target="models"`, `public=true`) |
| Read the contract | `model_schema_get`, before every `model_run`                                                           |
| Estimate cost     | `model_run` with `dry_run=true`; `cost_impact: true` marks the fields that move price                  |
| Generate or edit  | `model_run`, then `jobs_wait`                                                                          |
