# 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. Capability metadata (route triggers, prerequisites, load map, artifact contract) lives in [`routing.yaml`](routing.yaml). Agent table + dispatch graph + 4-sub-critic gate: [`references/agent-manifest.md`](references/agent-manifest.md). Methodology: [`references/playbook.md`](references/playbook.md). **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 — load first 1. **Soft-required: `research-shortform` 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`. 6. **Variants are TRUE RECUTS, not caption-resizes.** `platform-ta
