Format adaptation is derivation, not regeneration: re-prompting the concept per placement makes five cousins, not five formats of one approved master. 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. 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 <name>); unattended, proceed from tool schemas and flag the gap.
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 | \nOperation | \n
|---|---|
| Same ratio, other pixels | \nResize: exact, scales pixels, invents nothing | \n
| A tighter ratio, edges expendable | \nResize with fit: \"cover\": exact, center-crops the overflow; only when the subject clears the cut | \n
| More canvas, composition intact | \nExpand or uncrop: exact pixels, fills outward | \n
| Another ratio, recomposed around the subject | \nGenerative reframe; the text-protecting variant when lettering or marks are on the plate | \n
| A far ratio or a new visual hierarchy | \nRecompose natively: a fresh run per scenario-image with the master as reference (scenario-consistency), composed for that ratio | \n
The last rung applies more often than it looks: 16:9 key art seldom survives to 9:16 by any amount of outpainting, which is why the director siblings (scenario-video-ads) design each delivery ratio as its own composition.
scenario-image-editing holds the pipeline order). A video reframe also precedes any upscale: it renders at its own resolution tier whatever the input carries (1080p at most at authoring time), so an upscale ahead of it is discarded; upscale the reframed clip to delivery size.asset_analyze (scenario-asset-analysis).scenario-text-overlay, sized to each final canvas, since type scaled by a resize turns soft and each placement has its own safe area. Keep critical content and text away from the edges platform UI covers: each placement's target and safe zone is in references/placement-specs.md as an authoring-time value, so confirm contractual specs with the user (unattended, task instructions win over the reference, and the delivery report states which was used).scenario-image with the master as reference and a 9:16 composition clause; the master holds palette and subject on-look.asset_display the result and judge it small: thumbnails are seen at a tenth of their size.asset_analyze pass, then overlay the title card per format onto each final canvas and file the set in a collection.fit: \"stretch\"): it distorts. A ratio change is fit: \"cover\" when the edges are expendable, else reframe, expand, or recomposition.dry_run on reframes: generative canvas work is the expensive step in the chain, tens of times an effect's price (scenario-image-editing).
