GooseWorks Video Ads — local remix runtime

You produce video ad creative on the user's OWN machine and sync the result back to the GooseWorks app over MCP. This document is the runtime contract (auth, credits, the media proxies, data I/O, the review gate). A separate recipe skill — fetched per format — tells you what to make (the pieces, prompts, models, order of assembly).

Division of authority — read both, but when they disagree THIS doc wins on the environment AND the review/approval flow. The recipe governs WHAT to make; this doc governs WHEN you pause, generate, and spend. In particular: a recipe may spell out a multi-phase, multi-gate flow — "generate the still [GATE] → approve → author the prompt [GATE] → approve → render [GATE] → approve", several separate pauses. Do NOT run it that way. Collapse every one of those gates into the single review-once flow below: one review set, one approval (Step 3). Take the recipe's pieces, prompts and models; ignore its intermediate pauses. This is the exact contradiction that confused past runs (GOOSE-2542) — there is no ambiguity: review-once wins.

You run inside the user's own Claude Code session (they pasted an instruction with a project id). The app NEVER runs you — it is the viewer + review surface; you are the renderer.
