seedance-20

Seedance 2.0 operating loop for agent-directed video work. Use this root skill to route, check facts, protect references, and keep prompts compact before loading specialized sub-skills.

Operating Loop

1. Intake: identify the user's goal, production phase, target surface, mode, duration, aspect ratio, references, audio needs, deliverables, and safety/IP risks.

2. Source gate: before platform claims, load [ref:api-status] and [ref:source-registry]. For Runway, Volcengine, or fal specifics, also load [ref:platform-surface-matrix].

3. Professional gate: if the user asks for film, ad, campaign, client, delivery, localization, color, sound, subtitle, post, QC, or multi-shot work, load [ref:pro-filmmaking-standards] before drafting.

4. Mode gate: choose T2V, I2V, V2V, R2V, FLF2V, edit, extend, or troubleshoot before writing prose.

   Mode availability is surface-specific: edit and extend exist on Dreamina and Ark routes; fal has no dedicated extend endpoint - to continue a clip on fal, prefer reference-to-video with the previous clip as a video reference (keeps motion and audio context), and chain image-to-video from its last frame as the fallback.

5. Capability check: when planning any shot, mode, or budget, load [ref:capability-map] to design into model strengths and around known limits before drafting.

6. Reference map: assign every asset one primary role: identity, first frame, last frame, product, environment, motion, camera, timing, audio, or style. State what must not transfer.

7. Multilingual gate: if the prompt uses Chinese, Russian, Japanese, Korean, Spanish, or code-mixed wording, load [ref:multilingual-community-examples] and preserve reference tags exactly.

8. Safety gate: route IP, likeness, voice, brand, real-person, graphic, or evasion-like wording through [skill:seedance-copyright] or [skill:seedance-filter].

9. Prompt build: route to [skill:seedance-interview], [skill:seedance-prompt], [skill:seedance-prompt-short], or a domain skill for camera, motion, audio, characters, VFX, style, recipes, or pipeline.

10. Quality pass: run anti-slop, check one visible beat, one primary camera move, physical light, sound intent, continuity anchors, constraints, delivery caveats, and source-date caveats.

11. Repair loop: if output fails, diagnose root cause before adding adjectives; use [skill:seedance-troubleshoot].

Load Map

Preserve reference tags exactly, keep prompts short, and never convert field-observed community tricks into official platform guarantees. For professional filmmaker requests, deliver the workflow object the role needs: shot list, shot contract, continuity ledger, prompt, post handoff, localization plan, or QC checklist.
