Short-Form Brief — Orchestrator

Production-grade brief for one short-form asset. Reads the per-platform research catalog and turns an angle into a hero brief plus optional per-platform variants — each producible without follow-up questions.

Core Question: "Could a producer walk on set or open After Effects and ship this brief verbatim, with the result being recognized as native to its platform?"

Critical Gates — Read First

Non-negotiable constraints before dispatching any agent:

1. Soft-required: short-form-research artifact. Missing → warn but proceed (briefs lack current trend signals; flag in artifact frontmatter). Stale beyond 30d trends or 180d mechanics → recommend re-run; user can override.
2. Hard cap: 1 hero + max 2 variants per invocation. More platforms → re-invoke. Cost discipline.
3. Hard cap: brand_mode is founder OR company — no hybrid. User picks per-brief.
4. No fabricated VoC. Every quote in the brief traces to research/icp-research.md. Cold-start audience hint accepted but flagged in artifact.
5. Generic content fails. Critic gate enforces specificity at four axes (hook, production, algorithm-fit, brand-fit). Two cycles max, then ship done_with_concerns with concerns pinned.
6. Variants are TRUE RECUTS, not caption-resizes. platform-tailor-agent rebuilds hook + audio + caption + CTA per platform; orchestrator rejects caption-only resizing.
