Key decisions
Check whether camera continuity, transition logic, and action resolution all hold in the final result.
Adapt it to your subject
Extract “target result → the subject, scene, camera movement, and final action → constraints” as a reusable template for similar work.
Where it breaks
Run single-variable comparisons around shot length, transitions, and motion amplitude. Record the model, cost, and failures; turn it into a Skill only after it repeats reliably.
