name: image-storyboard-consistency description: Use when creating or QAing image packs for video: character identity sheets, three-view character sheets, scene boards, product boards, storyboard panels, style references, and multi-image consistency checks.

Image Storyboard Consistency

Use this skill whenever images are preproduction assets for video. The goal is not one nice image; it is a consistent asset pack the video pipeline can reuse.

Asset Packs

assets/reference-sheets/characters/
assets/reference-sheets/scenes/

plans/prompt-pack.json

Character Sheet Contract

{
  "characterId": "protagonist",
  "identityAnchors": ["face shape", "hair", "wardrobe", "age"],
  "views": [
    {
      "kind": "front",
      "assetId": "asset-front",
      "assetPath": "assets/reference-sheets/characters/protagonist-front.png",
      "locked": true,
      "copyOnWriteRequired": true
    },
    {
      "kind": "side",
      "assetId": "asset-side",
      "assetPath": "assets/reference-sheets/characters/protagonist-side.png",
      "locked": true,
      "copyOnWriteRequired": true
    },
    {
      "kind": "back",
      "assetId": "asset-back",
      "assetPath": "assets/reference-sheets/characters/protagonist-back.png",
      "locked": true,
      "copyOnWriteRequired": true
    }
  ],
  "negativePrompts": [],
  "locked": true
}

Storyboard Rules

Current local planner:

clash production plan-storyboard-review \
  --target-asset asset-storyboard \
  --characters storyboards/characters.json \
  --scenes storyboards/scenes.json \
  --panels storyboards/panels.json \
  --out actions/storyboard-review.json \
  --json

Review the action JSON, then run clash production apply-metadata to emit the storyboard projection, register panel assets in assets/manifest.json when panel entries include assetId and project-relative path, and register character reference sheets when character entries include referenceViews. This does not run embedding/OCR QA.

Use referenceViews in storyboards/characters.json when locked character sheets already exist as files:

{
  "id": "hero",
  "name": "便利店店员",
  "referenceAssetIds": ["asset-hero-front", "asset-hero-side", "asset-hero-back"],
  "requiredViews": ["front", "side", "back"],
  "referenceViews": [
    {
      "view": "front",
      "assetId": "asset-hero-front",
      "path": "assets/reference-sheets/characters/hero-front.png",
      "locked": true,
      "copyOnWriteRequired": true
    }
  ]
}

Managed apply attaches image.character-reference-sheet metadata to each declared asset with downstreamUsage: "identity-reference". Do not point this field at a mutable draft file; create a new asset id for revisions.

To prepare image/video generation prompts without mutating canvas state, project an observed prompt pack, edit the JSON file, then apply it explicitly:

clash production project-storyboard-prompt-pack \
  --action actions/storyboard-review.json \
  --out plans/prompt-pack.json \
  --style "vertical short drama, cinematic light" \
  --negative "logo drift, extra fingers" \
  --json

clash production apply-storyboard-prompt-pack \
  --file plans/prompt-pack.json \
  --json

clash production replace-storyboard-prompt-pack \
  --file plans/prompt-pack.json \
  --json

Managed apply writes projections/storyboards/<asset>.prompt-pack.json. If the managed prompt-pack changed since it was projected, apply is rejected. Project again and reconcile, or use replace-storyboard-prompt-pack when the edit should become a versioned copy-on-write prompt-pack projection while existing downstream references keep pointing at the old managed projection.

To turn approved storyboard panel assets into a timeline view, project them explicitly:

clash production project-storyboard-timeline \
  --action actions/storyboard-review.json \
  --duration-per-panel 45 \
  --json

clash production verify-storyboard-timeline \
  --action actions/storyboard-review.json \
  --manifest projections/timelines/asset-storyboard.storyboard.timeline-manifest.json \
  --min-consistency 0.75 \
  --out qa/storyboards/asset-storyboard.timeline-verification.json \
  --json

This writes a clash.storyboard.timeline-projection manifest and projections/timelines/<asset>.storyboard.timeline.yaml with image timeline items. It records the required pull/apply contract and creates no lock sidecar. The verification report proves panel coverage, timeline item coverage, fresh-pull CAS, local asset paths, and panel consistency thresholds before the timeline projection is applied.

Before moving storyboard panels into video generation, run the executable consistency QA planner:

clash production plan-storyboard-consistency-qa \
  --target-asset asset-storyboard \
  --characters storyboards/characters.json \
  --scenes storyboards/scenes.json \
  --panels storyboards/panels.json \
  --out actions/storyboard-consistency-qa.json \
  --report projections/storyboards/asset-storyboard.consistency-qa.json \
  --min-consistency 0.75 \
  --json

This writes a QA report and a normal image.storyboard-consistency metadata-fill action. The current QA is deterministic: required reference views, panel scene/character references, panel asset paths, and panel consistency score thresholds. It does not perform visual embedding, OCR, or logo checks yet.

• Separate identity reference, scene reference, and action prompt.
• Store prompt pack and generated panel ids.
• Give generated storyboard panels stable assetId values and local project-relative path values so apply can register them as assets.
• Do not overwrite approved references; create variants.
• For product images, preserve packaging, logo, color, and legal claims.
• Run consistency QA before video generation.

QA Dimensions

• character identity;
• wardrobe and props;
• scene continuity;
• product/logo accuracy;
• composition and safe area;
• temporal continuity across panels;
• style drift.

Migration Notes

Multi-image generation research clusters around multi-view, character, temporal, and semantic consistency. For Clash, these become separate analysis dimensions attached to image assets and storyboards.
