black-forest-labs FLUX 3 Video Router
Route a request to the smallest set of specialists that can complete it. When the request already names one narrow job, use that specialist directly.
| User intent | Skill |
|---|---|
| Diagnose or repair a brief before generation | flux-3-prompt-doctor |
| Write a text-to-video prompt for a new shot | flux-3-cinematic-inserts |
| Build from supplied images or video | flux-3-keyframes-continuation |
| Direct dialogue, voiceover, ambience, effects, or music | flux-3-audio-dialogue |
| Give a shot a period or archival look | flux-3-archival-formats |
| Submit, poll, enhance, download, or technically review | flux-3-generate |
| Build a finished product ad with voiceover | flux-3-product-ads |
Default sequence, skipping completed stages:
Prompt Doctor (until READY; owns the shot-structure decision)
→ Cinematic Inserts OR Keyframes & Continuation (one, chosen by whether
supplied media must constrain the result)
→ Audio & Dialogue (only when sound matters)
→ Generate (only when execution is requested)
Draft before committing anything unproven: a full render takes minutes, and the chosen draft replays at full quality.
A handoff between skills carries: outcome, the route (mode plus its media field:
t2v, i2v/keyframes, v2v/start_video, or draft_enhance/draft_cache), the
one required action, source roles, invariants, delivery (duration, aspect, resolution,
shot structure), camera, audio, text strategy, and risks. It is complete when the
receiving skill can act without inventing a consequential choice.
Deterministic requirements (exact typography, frame-accurate sync, final mixing) need an explicit post-production plan, not a generation attempt.
