seedance-motion

seedance-motion is a skill for Claude Code from Emily2040/seedance-2.0. It costs 45 tokens per session (1,165 once invoked), scanned A, original, MIT.

A Seedance 2.0 video-generation guide for describing visible body actions, choreography, object movement, timing, physics, and motion references.

In plain words
What is it for?
Use it to plan stunts, gestures, dances, moving objects, action continuity between shots, and motion based on video references.
Why use it?
It makes movement easier to follow by giving each action a clear subject, timing, physical consequence, and endpoint.

About the project

seedance-2.0 is an agent-driven production pipeline for creating AI films from text, images, videos, and references, including audio and platform-specific workflows. Filmmakers and creators use it to plan scenes and generate coherent prompts for Seedance-related tools, while the catalogue contains skills from that workflow.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

seedance-motion scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

seedance-motion

Before producing prompt text, a prompt-ready block, a rewrite, an example, or a compiled clip, load the Director's Read, classify the brief, and complete its canonical narrative or non-narrative record. Translate that record into visible or audible carriers and keep its internal labels out of final generation prose.

Use physical verbs and consequences. Motion should be observable on screen, timed within the clip, and assigned to a subject or object. Prefer one strong action with a visible endpoint over several vague actions competing for attention.

Load reference-workflow for video-motion references, shot-list-continuity for action handoffs across shots, examples-by-mode for safe edit, extend, and R2V patterns, and directing-engine when motion is performance: translate the scene's emotion into one true visible gesture per beat - a playable action with an objective and subtext - instead of an emotion word the model cannot render.

Intent

Motion is the verb of the user's story - the thing they came to see HAPPEN. The soul here is consequence: motion that begins, lands, and changes something feels lived; motion that loops feels generated. Every action carries the story one beat forward, or it doesn't belong in the clip.

Motion Contract

State: actor/object, action, force level, timing, physical consequence, continuity requirement, and endpoint.

Motion type Strong phrase Weak phrase
Subtle acting Character A inhales, grips the cup tighter, then sets it down without looking away she feels nervous
Product material condensation beads gather, merge, and slide down the bottle neck the product looks refreshing
Choreography Character B ducks under the swinging bag, pivots left, and stops in a guarded stance fast action fight scene
Object physics paper receipt lifts in the fan breeze, flips once, and lands face-up papers move dynamically
Environmental motion rain streaks diagonally across the backlight while puddle ripples spread from footsteps stormy weather atmosphere

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

seedance-motion is a skill published in the GitHub repository Emily2040/seedance-2.0 (7,279 stars, last pushed 4d ago), licensed MIT. It adds 45 tokens to every session and 1,165 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
