Algorithmic Art with p5.js
anthropics/skills
Creates original generative art in two steps: a written algorithmic philosophy, then a p5.js sketch with seeded randomness and an interactive viewer for exploring parameters.
Use p5.js/canvas for local procedural character effects: particles, weather, squash/stretch, walk cycles, and environmental motion.

What it does
Canvas Procedural Animation is an agent skill from calesthio/OpenMontage. Use p5.js/canvas for local procedural character effects: particles, weather, squash/stretch, walk cycles, and environmental motion.
Its SKILL.md is about 320 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Generative and creative coding. The repository describes itself as: World's first open-source, agentic video production system. 12 production pipelines, 100+ tools, 700+ agent skill and production-knowledge files. Turn your AI coding assistant… The licence is MIT.
When your agent uses it
- Tasks that involve Generative and creative coding
Example prompts
- “/canvas-procedural-animation”
What it can do on your machine
Read from SKILL.md and the folder at commit 9327439. 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
Links to these hosts (documentation or services it may open):
p5js.org
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
Canvas Procedural Animation loads about 323 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 104 words of instructions outside code blocks.
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.

Canvas Procedural Animation
Use this skill when p5.js or Canvas is used for character-supporting motion: rain, snow, leaves, feathers, ambient particles, squash/stretch, or procedural walk cycles.
Proven Pattern
p5.js runs setup once and redraws continuously through draw(). Keep animation
state deterministic from time/frame values when rendering previews.
function setup() {
createCanvas(1920, 1080);
}
function draw() {
const t = millis() / 1000;
clear();
drawCharacter(width / 2, height / 2 + sin(t * 8) * 8);
}Use For
- Particle/weather overlays.
- Environmental motion.
- Simple procedural bodies.
- Effects that do not need individually authored SVG parts.
Avoid For
- Complex facial acting where SVG/layered rig parts are easier to inspect.
- Final renders that need exact frame determinism unless the runtime exposes frame-index control.
