Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.01076 |
| Opus 5 | $0.00023 | $0.00538 |
| Sonnet 5 | $0.00009 | $0.00215 |
| Haiku 4.5 | $0.00005 | $0.00108 |
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.
This is a copy
95% identical to seedance-motion — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
seedance-motion
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 [ref:reference-workflow] for video-motion references, [ref:shot-list-continuity] for action handoffs across shots, [ref:examples-by-mode] for safe edit, extend, and R2V patterns, and [ref: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 |
Physics-Forward Pattern
Official material claims strong physics; extract it by writing causes and letting the model compute consequences (field-observed emphasis - test before promising results). State mass, force, and material, then name one consequence the camera can see: the heavy oak door swings shut and the candle flames bend toward it beats the door closes dramatically. Consequences prove the action: weight shows in landing compression, momentum in overshoot and recovery, friction in skid length, wind in what it displaces. One physical cause with two or three visible consequences reads stronger than three separate actions.
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 LeoYeAI/seedance-skills (39 stars, last pushed 2mo ago), licensed MIT. It adds 45 tokens to every session and 1,076 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 95% identical to seedance-motion, differing in 6 lines, and is treated as a copy.
