What problem does it solve? When an AI assistant builds a video in code, it routinely oversteps: judging creative quality it cannot judge, treating estimated durations as facts, inventing constraints, and writing notes that make no sense to the next reader. This Skill defines the working rules that prevent those failures across every stage of a video project. ## Core Features & Use Cases - Decision Boundaries: Separates what the assistant may verify (rendering, resolution, safe areas, file agreement) from what the human judges (pacing, humour, composition, meaning). - Timing Discipline: Establishes that durations are estimates until the video is built and watched, and that edits must never be driven by target-length arithmetic. - Durable Documentation: Rules for writing notes, storyboards, and plans that a first-time reader can use, with intent at the head and dated measurements appended at the foot. - Use Case: While building a Remotion film, the assistant is asked to trim a scene to hit a 60-second target. Following this Skill, it reports the overrun instead of cutting, and lets the person decide. ## Quick Start Ask the assistant to review the current video project against the working-practice rules before setting any durations or calling the work finished.
