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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00079 | $0.00640 |
| Opus 5.5 | $0.00032 | $0.00256 |
| Sonnet 5.5 | $0.00016 | $0.00128 |
| Haiku 4.5 | $0.00008 | $0.00064 |
Grade A, and why
like-burst 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 1mo 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.
What it actually says
like-burst
A celebratory particle burst for like / favorite / reaction buttons. Part of
motion-anything; obeys MOTION-SPEC.md.
When to use it
- Like / favorite / upvote / reaction buttons.
- A small, earned moment of positive feedback.
When NOT to use it (restraint)
- Destructive or neutral actions (delete, dismiss, close).
- When more than one burst could fire at once — one celebratory moment per screen.
- On load / autoplay. This must be user-triggered.
How to apply
- Copy
like-burst.cssandlike-burst.jsinto the project. - Link them, and mark the button:
<link rel="stylesheet" href="like-burst.css" /> <button class="like-btn" data-like-burst aria-pressed="false" aria-label="Like">♥</button> <script src="like-burst.js"></script> - It auto-attaches to any
[data-like-burst], or callattachLikeBurst(el)manually.
Tuning
PARTICLE_COUNT/COLORSinlike-burst.js(keep particle count modest — taste over spectacle).- Pop feel: the
lb-popkeyframe (currently420ms, ease-out). Burst spread:distinspawnParticles.
Accessibility & performance
- Honors
prefers-reduced-motion: particles are suppressed, a quiet color/scale cue remains. - Animates
transform/opacityonly; removes injected particle nodes after ~700ms.
Framework notes
- React: call
attachLikeBurst(ref.current)inuseEffect; or port the click handler into your component and keep the CSS as-is.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

like-burst is a skill published in the GitHub repository nexu-io/motion-anything (993 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 79 tokens to every session and 640 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-03.
