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 | $0.00052 | $0.00672 |
| Opus 5 | $0.00026 | $0.00336 |
| Sonnet 5 | $0.00010 | $0.00134 |
| Haiku 4.5 | $0.00005 | $0.00067 |
Grade A, and why
seedance-vfx scanned grade A with 1 finding 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts
The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
seedance-vfx
VFX prompts need material behavior, source, timing, and consequence. Treat every effect as physical: it starts somewhere, interacts with light and objects, changes over time, and ends in a visible state. Avoid generic words such as magical, explosive, or cinematic unless they are translated into particles, fluids, smoke, light, debris, deformation, or energy behavior.
Intent
The user wants wonder, and wonder dies the moment it stops obeying physics. This skill's purpose is magic with a budget of cause and effect: every effect has a source, a journey, and an ending, so the impossible reads as witnessed rather than rendered.
Effects Contract
State: effect source, material, motion path, interaction with light, interaction with objects, dissipation, and endpoint.
| Effect | Prompt-ready phrase | Stability note |
|---|---|---|
| Product particles | gold dust particles spiral from behind the logo, catch the backlight, then settle on the table |
Keep logo and bottle rigid. |
| Energy | thin blue electrical arcs crawl along the cable, briefly illuminating fingerprints on the plug |
Keep arcs attached to source. |
| Smoke | cold white vapor rolls over the rim, sinks down the glass, and thins near the tabletop |
Describe density and direction. |
| Transformation | paper edge chars inward from the corner, flakes curl and fall, final logo remains untouched |
Protect identity anchor. |
| Weather | wind pushes rain diagonally across the frame, puddles ripple outward from each step |
Tie weather to surfaces. |
VFX Integration Rules
Use one hero effect per clip. Anchor the source to a clear object or body part. Make the effect respect gravity, wind, collision, reflection, and occlusion. For VFX near faces, hands, logos, or text, keep the core identity stable and place the effect around it rather than through it.
Timing and Dissipation
Effects need an endpoint: settle, fade, evaporate, freeze, collapse, glow out, or leave residue. If the effect is complex, use a three-step timing phrase: forms -> travels -> dissipates. Avoid perpetual effects with no consequence because they often become noisy overlays.
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-vfx is a skill published in the GitHub repository mrDesign-ww/vault-os (2 stars, last pushed 4d ago), licensed MIT. It adds 52 tokens to every session and 672 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 91% identical to seedance-vfx, differing in 6 lines, and is treated as a copy.
