Product ad shot design
Turn the method into an executable, Case-grounded workflow. The Skill is incomplete unless the final artifact can be traced to one named anchor Case.
Inputs
Ask only for missing inputs:
- Target duration, aspect ratio, model, and delivery platform.
- Opening frame, ending frame, reference image, source video, or depth/motion guide when available.
- Character, camera, action, continuity, sound, and special-operation requirements.
- Preferred anchor Case from
references/cases.md, or permission to select one.
Required evidence gate
- Read
references/cases.mdbefore drafting on every invocation. - Select exactly one anchor Case. Name it in the response; do not average several unrelated visual styles.
- Inspect the anchor's finished media with an available image, video, or browser tool. If the media cannot be inspected, say so and do not claim visual fidelity.
- Write a reference contract before the artifact:
- Preserve: at least three structural traits supported by the Case evidence.
- Replace: subject, copy, brand, or context supplied by the user.
- Avoid: unrelated dominant motifs and superficial copying of creator identity.
Workflow
- Restate the requested deliverable, audience, and success criteria.
- Read
references/cases.mdand select one anchor Case. - Inspect its finished media, summary, and prompt excerpt.
- Produce the Preserve / Replace / Avoid reference contract.
- Choose one product benefit.
- Prove it through action or context.
- Close on brand detail or a call to action.
- Produce the requested artifact using the output contract below.
- Compare it with the anchor Case, then revise material failures once.
Output contract
- A reference contract naming one anchor Case, with Preserve, Replace, and Avoid decisions.
- A shot-by-shot motion brief.
- A complete video prompt with timing, camera, action, continuity, and audio constraints.
- A reference-assets and special-steps checklist.
- A short verification checklist for motion and continuity.
Verification
- Every shot has a subject, action, camera instruction, and duration or sequence position.
- Reference media and special preprocessing steps are named instead of implied.
- Continuity risks such as identity drift, limb errors, direction changes, and rhythm breaks are testable.
- The response names one anchor Case and confirms that its evidence file was read.
- At least three visible or structural traits in the artifact map back to the Preserve list.
- No unrelated theme becomes dominant unless the user explicitly requested it.
- If finished media was inaccessible, the response labels the result as prompt-grounded rather than visually verified.
- Distinguish observed evidence from your own recommendation.
- Link or name the relevant GoodCase evidence used for the artifact.
Safety and attribution
- Do not invent an original prompt, model, result, creator, metric, or source.
- Do not imply this Skill is authored, endorsed, or officially distributed by a referenced creator.
- Preserve creator attribution when reproducing or discussing a source Case.
- Transfer structure and decision logic; do not impersonate a creator or present a close copy as original work.
- Do not publish, purchase, upload private assets, or make external account changes without explicit user approval.
