# Seedance 20

> This skill should be used when creating, improving, or troubleshooting Seedance 2.0 video on any surface — Dreamina, Jimeng, CapCut, Doubao, Volcengine/Ark, BytePlus, Runway's Seedance route, fal, or third-party provider/router surfaces such as EvoLink, OpenRouter, Kie.ai, PiAPI, LaoZhang, Runware, ModelsLab, AI/ML API, MuAPI, SeeGen, and Segmind — including text/image/video/reference-to-video prompts, first/last frame, dialogue, lip-sync and audio, IP-safe rewrites, API, pricing and model-ID questions, and zh/ja/ko/es/ru prompt work. Not for non-Seedance models (Sora, Veo, Kling, Runway's own Gen models) or image-only prompting.

# seedance-20

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.

## 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.
