At a glance

This skill should be used when the user asks for body action, choreography, physics, object movement, movement timing, action continuity, stunt direction, or motion-reference mapping in Seedance 2.0.

What it does

Seedance Motion is an agent skill from Emily2040/seedance-2.0. This skill should be used when the user asks for body action, choreography, physics, object movement, movement timing, action continuity, stunt direction, or motion-reference mapping in Seedance 2.0.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering AI video generation. It works with Seedance. The repository describes itself as: Comprehensive production pipeline for quad-modal AI filmmaking with Seedance 2.0. The licence is MIT.

When your agent uses it

  • Asks for body action
  • Object movement
  • Movement timing
  • Action continuity

Example prompts

  • “/seedance-motion”

What it can do on your machine

Read from SKILL.md and the folder at commit 4668457. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Seedance Motion loads about 1.3k tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 657 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 typeStrong phraseWeak phrase
Subtle actingCharacter A inhales, grips the cup tighter, then sets it down without looking awayshe feels nervous
Product materialcondensation beads gather, merge, and slide down the bottle neckthe product looks refreshing
ChoreographyCharacter B ducks under the swinging bag, pivots left, and stops in a guarded stancefast action fight scene
Object physicspaper receipt lifts in the fan breeze, flips once, and lands face-uppapers move dynamically
Environmental motionrain streaks diagonally across the backlight while puddle ripples spread from footstepsstormy 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.

Timing Pattern

Use a three-beat structure for short clips: setup, action, changed end state. Example: 0-2s: candle flame steady; 2-4s: door opens and flame bends; 4-6s: smoke trail curls toward the hallway. Time segmentation is useful for action, VFX, lip-sync, and product demonstrations, but avoid frame-perfect overload unless the user truly needs it.

When sound drives the motion, pair each visible change with one beat or SFX: door click at 2s, light pulse on the downbeat, hand releases the cup on the final chime. Do not ask for many cuts, locations, and micro-actions inside one short clip.

Reference Motion Rules

For reference footage, use only owned, licensed, public-domain, stock, mocap, rehearsal, or self-recorded material. Map @Video1 to motion, camera, timing, or blocking, not identity, unless the identity is authorized. If a reference contains a real person, transfer only general motion or camera behavior and explicitly exclude likeness transfer.

Stability Rules

Hands, faces, logos, and product geometry drift when too many actions occur. Reduce motion around fragile details: lock the camera for lip-sync, keep hands in simple poses, ask product parts to remain rigid, and move light or environment instead of the core identity anchor.

Sequence State

When sequence state is present, inherit the observed action phase, open motion vector, current clip scope, continuity locks, exact reference tags, and reserved future beats. Do not replay actions marked already happened or completed. Do not perform a reserved beat early; carry unfinished motion from the accepted end state into the next clip.

Output Contract

Return the motion phrase, timing pattern, reference role map if any, and repaired prompt language.
