Seedance 2.0 Skill OS

Direct the model. Don't micro-manage the frame.

An agent that directs Seedance 2.0 like a filmmaker — reading each scene before it writes the prompt.
Text, image, video, and reference to video with native audio, IP-safe rewrites, source-dated platform facts, and native reader paths for English, 中文, 日本語, and 한국어.

Updated: 2026-07-04 · v6.6.0 the loop closes: frame-extraction observation tooling, state lifecycle for long projects, and the worked end-to-end trace

Direct the scene, don't decorate it

Most tools ask the model for a "cinematic look." A director asks what the scene is doing — then makes the camera, lens, light, blocking, performance, and sound all serve one intention, in a single recognizable voice, across an entire story.

The directing engine encodes that judgment. It reads a scene's dramatic function — the turn, the point of view, the power, the subtext — names one intention, and derives a coherent setup instead of stacking adjectives.

Ask for "cinematic": epic cinematic shot of a woman reading a letter, emotional, beautiful lighting

Direct it: Medium close-up, eye-level; she lowers the letter and her hands go still as a slow push-in arrives; soft window light behind her keeps her face plain; near-silence with one chair scrape — the realization lands in the stilled hands, not a word.

It then holds one directorial voice across every short clip of a long story, and ships with 35 worked derivations — product, music video, horror, anime, action, comedy, documentary, high fashion, sci-fi, and more — each shown end to end.

A reveal is not lit, framed, blocked, or performed like a goodbye. The engine refuses the generic answer and derives the specific one.

Native Language Start / 多语言入门 / 多言語スタート / 다국어 시작

Seedance 2.0 Skill OS is English-readable, but the v6 line gives Chinese, Japanese, and Korean readers first-class entry points, active example skills, and native prompt guidance. Keep reference tags exactly as written ([Image1], [Video1], [Audio1], @图1, @视频1) in every language.

Language	Start path	Native reader note
English	`seedance-prompt`, `seedance-sequence`, `references/vocab/en.md`	Use precise production English: one visible beat, one camera move, real light, and clear reference roles.
中文	`中文指南`, `seedance-vocab-zh`, `seedance-examples-zh`, `references/vocab/zh.md`	中文用户可从角色锁定、首尾帧、运镜、动作节奏开始；提示词要短、具体、保留参考标签，不把字幕交给模型生成。
日本語	`日本語ガイド`, `seedance-vocab-ja`, `seedance-examples-ja`, `references/vocab/ja.md`	日本語では、人物の同一性、衣装、構図、動きの終点を明確に書き、字幕や広告コピーは後処理で追加します。
한국어	`한국어 가이드`, `seedance-vocab-ko`, `seedance-examples-ko`, `references/vocab/ko.md`	한국어 프롬프트는 인물 고정, 카메라 움직임, 조명, 사운드를 짧게 분리하고 자막과 문구는 편집 단계에서 넣습니다.

For longer stories in any language, start with seedance-sequence. For the next part of an accepted clip, use seedance-continuation and update the observed final state before writing the next prompt.

Why this repository exists

Seedance 2.0 Skill OS is a modular agent-skill package for directing Seedance 2.0 video generations. It is built around a simple principle: direct the model, do not micro-manage the frame.

The repository gives an AI assistant a public, auditable operating system for Seedance work. It defines when to interview, when to write a compact prompt, when to load a technical reference, when to rewrite unsafe IP content, and when to troubleshoot a bad generation.

What This Skill Does

This skill package turns Seedance 2.0 work into a repeatable assistant workflow:

Routes vague ideas into short creative interviews instead of premature prompt dumps.
Directs each scene before drafting: reads its dramatic function, sets one directorial voice, and makes camera, light, blocking, performance, and sound serve a single intention instead of a generic "cinematic" look - and holds that voice across every clip of a long story.
Writes full or compressed prompts for T2V, I2V, V2V, R2V, FLF2V, edit, extend, audio-aware, and first/last-frame workflows.
Separates every reference asset by role: identity, environment, motion, camera rhythm, audio tempo, style, or endpoint.
Keeps model and platform claims source-dated so API, pricing, region, quota, and model-ID details are not guessed.
Plans into model strengths before drafting: a capability map, a fidelity-allocation model, and a working model of the generator's mechanics that explains why every rule works.
Runs the shoot like a producer after generation: five-verdict take triage, one-variable retakes, attempt budgets, and cost-aware drafting.
Provides native-reader front-page paths plus deeper multilingual cinematic vocabulary in English, 中文, 日本語, 한국어, Spanish, and Russian, including role binding, first/last-frame phrasing, edit/extend wording, safety wording, audio cues, continuation wording, and post-production text handling.
Adds original community-informed examples for Chinese, Japanese, Korean, Russian-English, and Spanish-English prompt structures.
Adds professional filmmaker workflows for treatment-to-shot-list planning, shot contracts, continuity ledgers, ACES/color handoff, audio post, subtitles/localization, aspect-ratio variants, campaign cutdowns, delivery/QC, and client review packets.
Handles safe false-positive repairs by clarifying benign production context, not by hiding unsafe intent.
Rewrites unsafe celebrity, protected IP, private-person, brand, logo, song, or voice requests into safer creative equivalents.
Diagnoses failed outputs with concrete repair levers: camera, lighting, motion, reference role, duration, framing, audio, or safety wording.
Ships validation scripts, eval cases, source data, and design checks so maintainers can review changes before release.

Making Videos Longer Than One Generation

Do not blindly ask the skill to extend the original prompt. A continuation must be based on accepted generated footage because Seedance may not end exactly where the original prompt expected.

Describe the complete idea and how it ends.
The skill divides it into connected clips.
Generate Clip 01.
Return the generated clip or its final frame.
The skill records what actually happened.
It writes Clip 02 from the real ending.
Repeat until the planned final outcome is reached.

The project state is the source of truth. The clip contract is the current production task. The prompt is a compiled instruction for only that task. Accepted generated footage determines what happens next.

Professional Filmmaker Scope

This package is designed for working film and commercial teams, not only for casual prompt writing. It can help an agent produce the artifact the role actually needs:

Role	What the skill should produce
Director	treatment, scene beat, performance intent, coverage, shot endpoint, review notes
Cinematographer / DP	shot contract, shot size, lens feel, camera support, movement, blocking, lighting continuity
Producer / agency	client brief, rights map, approval gates, campaign variants, risk log, review packet
Editor	selects plan, edit/extend decision, continuity handoff, handles, textless needs, conform notes
Colorist	color intent, ACES-aware handoff, show-look notes, HDR/SDR caveats, product-color checks
Sound team	dialogue map, ambience/SFX/music layers, sync cues, stems, M&E, dubbing and loudness notes
Localization team	subtitles, SDH captions, forced narratives, dubbing guide, market copy, textless plates
Delivery/QC	frame rate, aspect ratio, crop, color, loudness, captions, metadata, naming, human QC checklist

For these requests, the skill should not stop at a single prompt. It should return the production object first, then the Seedance prompt or prompt batch that fits inside that plan.

Current Status Rule

Seedance platform behavior changes quickly. Before making factual claims about API availability, face or portrait authorization, upload limits, pricing, regional availability, or model names, load references/api-status.md and check its last_verified date.

As of 2026-06-20, public official sources describe Seedance 2.0 as supporting text, image, audio, and video inputs. Official launch and model-card material says references can include up to 9 images, 3 video clips, and 3 audio clips.

Volcengine and BytePlus docs now expose Seedance 2.0 Mini as a surface-specific model lane. Treat Seedance V2 Mini as shorthand for Seedance 2.0 Mini only when the active surface confirms it. Current source-visible IDs include doubao-seedance-2-0-mini-260615 on Volcengine and dreamina-seedance-2-0-mini-260615 on BytePlus.

Volcengine docs also keep doubao-seedance-2-0-260128 and doubao-seedance-2-0-fast-260128 visible as Ark model IDs and document first/last-frame role usage on that surface. Runway documents seedance2 with 5-15 second duration and optional image, video, and audio references.

Third-party provider/router pages tracked as of 2026-06-20 include EvoLink, OpenRouter, Kie.ai, PiAPI, LaoZhang, Runware, ModelsLab, AI/ML API, MuAPI, SeeGen, and Segmind.

Treat every endpoint, model ID, price, account requirement, face/reference policy, and output-rights claim as provider-specific and recheck live before implementation. China-facing searches should prefer official ByteDance, Volcengine, BytePlus, Doubao, Jimeng/Jianying, and CapCut/Jianying surfaces; workflow hosts or business-partner news are not public API providers unless they publish provider-owned API docs.

Access, pricing, upload limits, regions, resolution, audio-combination rules, and authorization requirements remain surface-specific.

V6 Research and Claim Boundary

The v6 release line keeps a dated research layer for safer data mining, multilingual prompting, sequence-state work, and platform claims:

research-2026-05-30.md records official and field-observed signals.
platform-surface-matrix.md separates model capability from Dreamina/Jimeng, Volcengine/Ark, BytePlus, ComfyUI, and provider/router behavior.
model-name-map.md prevents Seedance 2.0, Seedance 2.0 Fast, Seedance 2.0 Mini, Seedance V2, and ambiguous Pro labels from being mixed together.
community-source-methodology.md explains how to mine public prompt corpora without copying unsafe examples.
multilingual-community-examples.md captures safe mixed-language and localized prompt structures from community pattern mining.
pro-filmmaking-standards.md adds industry workflow boundaries for shot lists, continuity, color, audio, localization, and delivery.

Operating System At A Glance

Seedance 2.0 Skill OS operating diagram: seven gates feed the seedance-20 root, which routes to the core pipeline, governance, and multilingual vocabulary clusters, backed by the reference library and validators

The diagram is the contract: every request passes the gates, the root routes it, and the validators hold the line. Six lanes stay separate by design:

Research sources: dated official, academic, platform, and community evidence.
Production spine: brief, shot list, continuity, post handoff, localization, and delivery/QC.
Prompt router: interview, prompt writing, compression, recipes, and troubleshooting.
Multimodal references: image, video, audio, first-frame, last-frame, and role-bound assets.
Safety gates: IP, likeness, voice, brand, real-person, filter, and platform-policy checks.
Quality evals: schema checks, source freshness, vocabulary integrity, design audit, and behavior cases.

Install

Client support for Agent Skills is still tool-specific. Codex documents a skill as a directory with a required SKILL.md, optional scripts/, references/, assets/, and optional agents/ metadata.

Codex scans .agents/skills locations from the working directory upward, plus user/admin/system skill locations. A repository root with SKILL.md is shaped like a skill folder, but it still needs to be installed/copied under a scanned skills directory or distributed as a plugin for automatic discovery.

This repository now includes agents/openai.yaml and a local Codex installer. To install it for this Windows workstation or any local Codex profile, run:

python scripts/install_codex_skill.py --force

The installer copies the repository into $CODEX_HOME/skills/seedance-20 when CODEX_HOME is set, otherwise into ~/.codex/skills/seedance-20. Restart Codex after installation so $seedance-20 appears in the available skills list.

This repository keeps dense facts in references so the active skill stays small.

If your client supports installing a skill directly from a GitHub repository, use this repository URL:

https://github.com/Emily2040/seedance-2.0

For manual installation, copy this repository into the skill directory used by your agent client. The directory name should match the root skill name, seedance-20. Treat the table below as common local targets to verify in your own client, not a universal support guarantee.

Platform	Typical install target (verify in your client)
Claude Code	`.claude/skills/seedance-20/`
Codex	`.agents/skills/seedance-20/` or `~/.codex/skills/seedance-20/` via `scripts/install_codex_skill.py`
Google Antigravity	`.agents/skills/seedance-20/` (workspace) or `~/.gemini/antigravity-cli/skills/seedance-20/` (global)
OpenClaw	workspace `skills/seedance-20/` or `~/.openclaw/skills/seedance-20/` via `openclaw skills install` (ClawHub-compatible; skills already carry `openclaw:` metadata)
Hermes Agent	project `skills/seedance-20/` or `~/.hermes/skills/seedance-20/` via `hermes skills install`
Gemini CLI-style workspace	`.gemini/skills/seedance-20/`
GitHub Copilot workspace	`.github/skills/seedance-20/`
Cursor workspace	`.cursor/skills/seedance-20/`
Windsurf workspace	`.windsurf/skills/seedance-20/`

Validation

Run these checks before every release:

python scripts/validate_skills.py --strict
python scripts/content_audit.py --strict
python scripts/eval_schema_check.py --strict
python scripts/design_audit.py --strict
python scripts/source_registry_check.py --strict
python scripts/vocab_schema_check.py --strict
python scripts/project_state_check.py --strict
python scripts/continuity_chain_check.py --strict
python scripts/behavior_contract_check.py --strict
python scripts/sequence_eval_check.py --strict
python scripts/generation_run_check.py --strict
python scripts/prompt_lint.py --self-test --strict
python scripts/eval_run.py --self-test --strict
python scripts/extract_last_frame.py --self-test --strict
python -m unittest discover -s tests -v
python -m compileall scripts tests
git diff --check

The CI workflow runs the same checks on push and pull request. These are deterministic and offline — they prove the package is well-formed.

To prove the package is also good, run the model-in-the-loop harness, which sends each eval case through the real skill content and scores the response against the case's assertions using eval-rubric.md:

export ANTHROPIC_API_KEY=...   # required for a live scored pass
python scripts/eval_run.py --run --ledger evals/eval-run-ledger.md --stamp 2026-06-28

This is the quality gate, not a shape gate, so it lives outside offline CI; the latest scored run is recorded in evals/eval-run-ledger.md.

Design Standard

The front page follows an editorial design system rather than default AI styling: warm ink and paper themes, a serif display face paired with monospace specification labels, a single amber accent, and fine-line film motifs — no gradients, no glow.

The masthead and operating diagram are hand-built theme-aware SVGs (assets/hero-dark.svg, assets/hero-light.svg, assets/skill-map.svg) served through a prefers-color-scheme picture element; generated bitmap art lives only in the curated visual gallery, including the text-rich infographics.

The README must stay readable in GitHub mobile, dark mode, and narrow widths. SVG assets must include <title> and <desc> elements, use internal CSS only, and avoid external fonts, scripts, or resources. Tokens and rules live in references/frontend-design-system.md and docs/frontend-redesign.md.
