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.
• 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.
• Provides deeper multilingual cinematic vocabulary in Chinese, Japanese, Korean, Spanish, and Russian, including role binding, first/last-frame phrasing, edit/extend wording, safety wording, and audio cues.
• Adds original community-informed examples for Chinese-English, Russian-English, Japanese-English, Korean-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.

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.

“This uses a character, brand, celebrity, or real person.”	seedance-copyright	A safer rewrite preserving the creative function.
“I need this for a film, client, campaign, or delivery.”	pro-filmmaking-standards	A professional workflow plan, role-specific artifact, and prompt path.
“Turn this treatment into shots.”	shot-list-continuity	Shot list, continuity ledger, and prompt batch structure.
“This needs subtitles, dubbing, color, sound, or QC.”	delivery-qc	Post, localization, audio, color, and delivery checks.
“I need API, Runway, pricing, model ID, or production workflow guidance.”	api-workflow	A source-gated operational checklist.
“Is this Seedance Pro/Fast/V2?”	model-name-map	Source-dated naming and surface caveats.

“I am installing or reviewing this as an agent skill.”	agent-compatibility	Codex/Agent Skills structure and distribution notes.

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 2026-05-30, 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's May 29 docs keep doubao-seedance-2-0-260128 and doubao-seedance-2-0-fast-260128 visible as current 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.

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

Research Snapshot

The v5.4 release line adds a dated research layer for safer data mining 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 wrapper behavior.
• model-name-map.md prevents Seedance 2.0, Seedance 2.0 Fast, 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

The operating-system map stays simple for GitHub readability; the visual gallery below adds the text-rich professional infographics. Together they represent the six lanes this package keeps separate:

• 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.

Visual Gallery

The README now includes a committed visual set rather than a single generic hero. These generated bitmap assets are paired with searchable Markdown so the images can be cinematic while the repo remains auditable.

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 workspace path
Claude Code / OpenClaw	.claude/skills/seedance-20/
Codex-style agent workspace	.agents/skills/seedance-20/
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

The CI workflow runs the same checks on push and pull request.

Design Standard

The v5.4.5 front page uses multiple generated cinematic bitmap hero shots, text-rich infographics, a generated operating-system infographic, a generated cinematic skill-map infographic, and the cleaned v5.2 information architecture. The README should 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 or scripts. See docs/frontend-redesign.md.
