# scenario-formats A decision ladder for shipping one approved master at many sizes and ratios through Scenario. Use it when one visual has to feed stories, feeds, banners and previews. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 394 installs · ★ 1141 - Author: scenario-labs - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/scenario-labs/skills/tree/HEAD/skills/scenario-formats/SKILL.md - Updated: 2026-10-23 - HTML: https://affpapa.org/en/nevibecode/skills/scenario-formats ## What it does The skill starts from one rule: format adaptation is derivation, not regeneration. Re-prompting a concept per placement gives you five cousins, not five formats of one master. So an approved text-free master comes first, and every derivative is built from that master alone. Inside is a decision ladder. Same ratio, different pixels — a plain resize. Tighter frame with expendable edges — `fit: "cover"`. More canvas — expand or uncrop. Another ratio, recomposed around the subject — generative reframe. A far ratio like 16:9 to 9:16 — native recomposition through `scenario-image` with the master as reference. The order of operations is strict: reframe and expand before grading and grain, because generative canvas work re-renders the image. Then verification by measurement — reframe ratio enums are approximate, a 4:5 request can return 29:36, so output dimensions get checked and landed exactly with a resize. Lettering goes last, per format, through `scenario-text-overlay`. The skill leans on siblings: `scenario-image-editing` holds the canvas tool contracts, `scenario-video-editing` does the same for video, `scenario-consistency` keeps the master's look. If one is missing, the skill asks the user to install it with `npx skills add`. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add scenario-labs/skills --skill scenario-formats -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/scenario-formats/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/scenario-formats/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add scenario-labs/skills --skill scenario-formats -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/scenario-formats/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add scenario-labs/skills --skill scenario-formats -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/scenario-formats/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install scenario-labs/skills scenario-formats ``` 2. **Manually: put the files in place** - File: `.github/skills/scenario-formats/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add scenario-labs/skills --skill scenario-formats -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/scenario-labs/skills --path skills/scenario-formats ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/scenario-formats/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add scenario-labs/skills --skill scenario-formats -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-formats/SKILL.md ## When to use it - spread one master across 1:1, 4:5, 9:16 and 16:9 - pick between crop, resize, expand and generative reframe - keep the subject alive when cropping to vertical - check that subjects survived recomposition - place lettering inside each placement's safe zone ## Example prompts - adapt this master to 1:1 for feed and 9:16 for stories - check dimensions of all derivatives and land exact pixels - recompose this 16:9 key art to vertical, keep the knight centered and both banners visible ## Source text · SKILL.md · MIT Below is the content of a third-party file.

The failure modes are picking the wrong operation (a resize where canvas needed inventing, a crop that beheads the subject) and deriving in the wrong order. The canvas tools' exact contracts live in `scenario-image-editing`; this skill is the decision ladder and the order of operations around them, with per-placement ratios, pixel targets, and safe zones in [references/placement-specs.md](references/placement-specs.md). A video master climbs the same ladder: video resize versus generative reframe lives in `scenario-video-editing`, and far ratios recompose per `scenario-video`. Connection and the core loop: see the `scenario` skill. Lettering per format: `scenario-text-overlay`. 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 `); unattended, proceed from tool schemas and flag the gap. ## The decision ladder Per target format, take the first rung that fits. Each rung is a `model_run` on a model found with `search` (`target="models"`, `public=true`), never a dedicated MCP tool of its own: | The target needs | Operation | | -------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------- | | Same ratio, other pixels | Resize: exact, scales pixels, invents nothing | ``` END THIRD-PARTY FILE b5a2770e31c2ee55 The third-party file has ended.
