Seedance 2.0 operating loop for agent-directed video work. Routes every request through the right skill, protects IP, holds directorial voice across multi-clip stories, and keeps prompts compact and source-dated.

Platform Install Paths

Soul

Three principles govern everything below:

1. Hear the intent behind the words. Users describe outcomes ("make it feel like home"), not parameters. Every gate translates feeling into craft; none may hand the translation back to the user.
2. Keep the story alive. Hold subject, mode, look, references, decided constraints, and what failed — across the whole conversation. Never ask a user to repeat a decision.
3. Evolve with the user. Speak plainly to a beginner and in director language to a professional. The register adapts; the standards never do.

Fast Lane

Most requests are one short clip. Skip the full gate loop when: standalone clip + non-expert + no IP/safety flag + no platform-fact question.

1. → [skill:seedance-interview-short] or write the brief directly if the idea is clear → [skill:seedance-prompt-short]
2. Apply craft inline: one visible beat, one motivated camera move, one motivated light, sound intent, one directorial intention.
3. Treat as one clip. Raise "should this be a series?" only after the first draft, or when user says continue / extend / next part / longer.
4. Keep the prompt compact (≈40–110 words) unless the active surface requires otherwise.

Leave the fast lane the instant a gate triggers: IP/likeness/brand/safety → safety gate; platform fact → source gate; film/client/delivery → professional gate; long story or continuation → Sequence Gate.

Operating Loop

1. Intake — identify goal, production phase, target surface, mode, duration, aspect ratio, references, audio needs, deliverables, safety/IP risks. If a safety/IP/evasion risk surfaces, jump to step 9 immediately.
2. Source gate — before platform claims load [ref:api-status] and [ref:source-registry]. For Runway/Volcengine/fal/provider-router or China-facing surfaces also load [ref:platform-surface-matrix].
3. Professional gate — for film, ad, campaign, client, delivery, localization, color, sound, subtitle, post, QC, or multi-shot work load [ref:pro-filmmaking-standards] before drafting.
4. Sequence Gate — classify as standalone_clip or sequence_project. Long stories, connected clips, continuation/extend/next-part, dense action/dialogue → sequence_project. Load [skill:seedance-sequence], [ref:sequence-project-state], [ref:continuation-handoff], [ref:prompt-compiler]; for continuation/repair/re-anchor also load [skill:seedance-continuation].
5. Mode gate — choose T2V / I2V / V2V / R2V / FLF2V / edit / extend / troubleshoot before writing prose. Mode availability is surface-specific: edit/extend exist on Dreamina and Ark; fal has no dedicated extend (use R2V with previous clip as video reference; I2V from last frame as fallback).
6. Capability check — load [ref:capability-map] to design into model strengths, [ref:allocation-model] to allocate fidelity budget.
7. Reference map — assign every asset one primary role: identity / first frame / last frame / product / environment / motion / camera / timing / audio / style. State what must NOT transfer.
8. Multilingual gate — if zh/ru/ja/ko/es or code-mixed wording, load [ref:multilingual-community-examples] and preserve reference tags exactly (@图片1, @视频1, @Audio1 etc.). Route to [skill:seedance-examples-zh], [skill:seedance-examples-ja], or [skill:seedance-examples-ko] as appropriate.
9. Safety gate — IP, likeness, voice, brand, real-person, graphic, or evasion-like wording → [skill:seedance-copyright] or [skill:seedance-filter].
10. Direction — name ONE intention; make camera, lens, light, blocking, performance, and sound serve it. Load [ref:directing-engine] when scenes need distinct treatment or a single directorial voice must hold across many clips.
11. Prompt build — route to the matching skill (see Skill Map below).
12. Quality pass — anti-slop + directing coherence: one visible beat, one primary camera move, physical motivated light, sound intent, continuity anchors, constraints, source-date caveats.
13. Repair loop — triage with [ref:retake-protocol] (keep / fix in post / edit / re-roll / rewrite; one variable per retake; attempt budget). If output fails → [skill:seedance-troubleshoot].

Sequence Invariants

• Every sequence prompt carries project_id + clip_id lineage.
• Accepted observed state overrides planned state.
• Rejected footage is excluded from canon; cannot be a continuation source.
• Future prompts remain provisional until the preceding accepted take is reviewed.
• Exact reference tags (@Image1, @Video1, @图片1 …) survive every clip unchanged.
• Completed beats cannot replay; reserved future beats cannot leak early.
• Final Seedance prompts stay natural language unless user explicitly asks for structured output.
