What it does

Ambient Section Particles is an agent skill from nirholas/three.ws. Add a restrained particle atmosphere inside one section with configurable shapes, density, gravity, wind, sway, rotation, recycling or settling, pointer disturbance, visibility pausing, responsive limits, and reduced-motion fallbacks. Use for petals, leaves, snow, sparks, confetti, dots, paper, icons, or brand fragments that support a section's mood without obscuring content.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files (for example `REFERENCES.md`, `agents/openai.yaml` and `demo/PROMPT.md`).

It sits in Frontend & Design. The repository describes itself as: Open-source platform for 3D AI agents. Turn text or a photo into a rigged, animated GLB avatar, give it an LLM brain, memory and a wallet, and embed it anywhere with one web… The licence is Apache-2.0.

When your agent uses it

Brand fragments that support a sections mood without obscuring content

Example prompts

“/ambient-section-particles”

Workflow steps

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

Give the section a positioning context and clip overflow when particles should remain bounded.
Place the particle surface behind content but above the background.
Set the layer to pointer-events: none; listen for pointer movement on the section.
Reserve a quiet content zone or lower density behind long text and controls.
Keep controls and links in normal DOM stacking with visible focus.

What it can do on your machine

Read from SKILL.md and the folder at commit 238ef60. 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 (its code samples are javascript).
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

Ambient Section Particles loads about 1k tokens when it runs. Until then it costs about 101 tokens; SKILL.md has 483 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~101
When it runs · the whole SKILL.md, loaded when a task matches: ~1k

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.

name: ambient-section-particles
description: Add a restrained particle atmosphere inside one section with configurable shapes, density, gravity, wind, sway, rotation, recycling or settling, pointer disturbance, visibility pausing, responsive limits, and reduced-motion fallbacks. Use for petals, leaves, snow, sparks, confetti, dots, paper, icons, or brand fragments that support a section's mood without obscuring content.

Ambient Section Particles

Build particles as a bounded atmosphere layer, not as a page-wide screensaver. Keep the content primary and stop work when the effect cannot be seen.

Choose the renderer

Use canvas for roughly 40 or more small particles, frequent motion, pointer forces, or simple procedural shapes.
Use DOM or inline SVG for a small count of branded fragments that need individual styling or semantic labels.
Use WebGL only for thousands of particles, depth, shaders, or real 3D behavior. Cap device pixel ratio and provide a static fallback.

Start with the least expensive renderer that preserves the desired shape language.

Define one configuration

const particles = {
  count: 54,
  gravity: 7,
  wind: -3,
  sway: 16,
  speed: [8, 18],
  size: [4, 12],
  opacity: [0.18, 0.62],
  rotation: [-0.8, 0.8],
  mode: "recycle",
  pointerRadius: 110,
  maxDpr: 2
};

Scale density by container area, then clamp it for mobile and low-power devices. Do not derive count from viewport width alone.

Layer the section

Give the section a positioning context and clip overflow when particles should remain bounded.
Place the particle surface behind content but above the background.
Set the layer to pointer-events: none; listen for pointer movement on the section.
Reserve a quiet content zone or lower density behind long text and controls.
Keep controls and links in normal DOM stacking with visible focus.

Run the simulation

Seed particles inside or just above the container bounds.
Update gravity, wind, phase-based sway, rotation, opacity, and position from elapsed time.
Clamp large time deltas after background tabs or stalled frames.
Use one requestAnimationFrame loop for the whole layer.
Resize with ResizeObserver; cap canvas backing resolution at min(devicePixelRatio, maxDpr).
For pointer disturbance, apply a small distance-based force and let particles settle back naturally. Never attach a listener per particle.

Support explicit end modes:

recycle: return particles above the section after exit.
exit: remove particles after they leave the bounds.
settle: resolve into a shallow visual pile with a strict height cap.
static: render a deterministic still composition.

Stop invisible work

Use IntersectionObserver to start only when the section is visible. Cancel animation frames when it exits or document.hidden becomes true. Resume from the current simulation state instead of spawning a second loop.

On teardown, disconnect observers, remove resize and pointer listeners, cancel the frame, and release renderer resources.

Respect the reader

Under prefers-reduced-motion: reduce, render a sparse static arrangement or remove the layer.
Keep particles decorative and hidden from assistive technology.
Control opacity and contrast so motion never crosses the legibility threshold.
Avoid full-screen pointer repulsion, rapid direction changes, flashes, and large objects crossing form controls.
Pause decorative motion while a modal or critical task in the section is active when it competes for attention.

Verify

Test entry and exit pausing, background-tab recovery, fast resize, 390/768/1440 widths, device pixel ratio, pointer and touch input, reduced motion, section overflow, content focus, long text, route cleanup, and console errors. Confirm only one animation loop survives repeated mounts.

Use demo/index.html as the working reference and demo/PROMPT.md to recreate or remix it. Keep REFERENCES.md as the links-only implementation source list.
