What it does

Like Burst is an agent skill from nexu-io/motion-anything. Add a celebratory particle burst to a like / favorite / reaction button. A delight micro-interaction that fires on user tap only (never on load), bursts on the "like" transition (not un-like), and ships a prefers-reduced-motion fallback. Use when a small, earned moment of positive feedback will feel good — and only one such moment per screen.

Its SKILL.md is about 610 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `like-burst.js` and `recipe.motion.yaml`).

It sits in Frontend & Design, covering Web animation and motion. The repository describes itself as: ✨ The agentic motion layer — an open-source, chat-native motion engine. Describe the feeling; your AI ships the animation. The licence is Apache-2.0.

When your agent uses it

  • Earned moment of positive feedback will feel good — and only one such moment per screen
  • Tasks that involve Web animation and motion

Example prompts

  • “/like-burst”

Requirements

  • Node.js

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Copy like-burst.css and like-burst.js into the project.
  2. Link them, and mark the button
  3. It auto-attaches to any [data-like-burst], or call attachLikeBurst(el) manually.

What it can do on your machine

Read from SKILL.md and the folder at commit b016900. 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

    Ships script files (JavaScript), which the agent can run.

    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

Like Burst loads about 612 tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 159 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~89
When it runs · the whole SKILL.md, loaded when a task matches
~612

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.

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

  1. Copy like-burst.css and like-burst.js into the project.
  2. Link them, and mark the button:
    html
    <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>
  3. It auto-attaches to any [data-like-burst], or call attachLikeBurst(el) manually.

Tuning

  • PARTICLE_COUNT / COLORS in like-burst.js (keep particle count modest — taste over spectacle).
  • Pop feel: the lb-pop keyframe (currently 420ms, ease-out). Burst spread: dist in spawnParticles.

Accessibility & performance

  • Honors prefers-reduced-motion: particles are suppressed, a quiet color/scale cue remains.
  • Animates transform/opacity only; removes injected particle nodes after ~700ms.

Framework notes

  • React: call attachLikeBurst(ref.current) in useEffect; or port the click handler into your component and keep the CSS as-is.
