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-prompt 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 today.

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.

The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.

seedance-prompt

Reference resolution: [ref:<name>] resolves to ../seedance-20/references/<name>.md (the seedance-20 skill's vendored reference corpus); [skill:<name>] is the sibling skill of that name.

Build production-ready Seedance prompts from clear concepts or supplied reference assets. Treat the prompt as a short shooting brief: it must say what changes on screen, what the camera does, what the light and sound contribute, and what must stay stable. Keep final prompts under the platform prompt budget and remove filler before delivery.

Load [ref:quick-ref] for the checklist, [ref:reference-workflow] for multimodal references, [ref:i2v-guide] for image-to-video, [ref:first-last-frame-guide] for first/last-frame work, [ref:examples-by-mode] when examples are useful, [ref:shot-list-continuity] for multi-shot professional plans, and [ref:multilingual-community-examples] for Chinese/Russian/Japanese/Korean/Spanish or mixed-language prompts.

Director Formula

Use Subject + Action + Scene + Camera + Lighting/Style + Audio + Constraints. Put the subject and primary action first because early clauses set the shot hierarchy. Do not force every slot if a reference asset already shows the information; for I2V, describe only the motion, camera, timing, transformation, audio, and preservation constraints that the still image cannot show.

Slot Use for Prompt-ready pattern
Subject The anchor the model must track. Original ceramic perfume bottle on black acrylic, label preserved exactly
Action The visible change. condensation beads form and slide down the glass over five seconds
Scene Only what is not already in references. quiet rain-lit kitchen counter, shallow depth of field
Camera One primary move with endpoint. slow dolly-in from medium product shot to macro label detail
Light and style Physical light plus safe visual language. warm practical key from frame left, cool blue rim, clean commercial realism
Audio Ambient bed, SFX, dialogue, or silence. Sound: low room tone, soft glass chime on final frame
Constraints Preservation and exclusions. do not alter logo, shape, label, or cap geometry
Timing Shot sequencing or time structure. 0-2s steady; 2-4s door opens, flame bends; 4-5s smoke curls toward hallway

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.
