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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 341 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00158 | $0.07049 |
| Opus 5 | $0.00079 | $0.03524 |
| Sonnet 5 | $0.00032 | $0.01410 |
| Haiku 4.5 | $0.00016 | $0.00705 |
Grade A, and why
threejs-particle-canvas 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 461 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Three.js Particle Canvas
Generate interactive Three.js canvases in six modes — from ambient particle narratives to physically-accurate 3D glass hero sections. Output is a single self-contained HTML file. No build step, no framework, runs offline.
This is NOT a 3D product viewer, game engine, or data dashboard. The viewer observes, explores, and contemplates — they do not control.
For full creative direction (typography, color commitment, spatial composition, anti-slop), activate minoan-frontend-design alongside this skill.
Quick Start
Describe a concept or narrative. Claude generates a complete HTML file with: particle system, phase cycle, lattice structure, spherical camera, star field, connection threads, responsive controls, CSS overlays.
Example: /threejs-particle-canvas the lifecycle of a star — nebula collapse, ignition, main sequence, red giant, supernova, remnant
Concept-to-Form
Every design decision derives from the concept. Do not pick defaults — derive.
Lattice geometry embodies the concept's skeleton. Icosahedron = persistent pattern (AI consciousness). Dodecahedron = organic complexity (botanical, cranial). Octahedron = crystalline structure (mineral, ruin, architecture). Torus = circulation and return (ocean currents, neural loops). None = formlessness (void, dream, dissolution).
Color temperature creates emotional contrast. Every palette requires genuine warm/cool tension. Two colors in the same temperature range produce flat, lifeless phases. The cool color dominates resting states; the warm color emerges during activation. The transition between them is the emotional engine.
Phase rhythm encodes narrative weight. The emotional center gets the longest phase. Bookending phases are shorter. Unequal durations create rhythm; equal durations create monotony. A 90s cycle might split: 10, 10, 15, 25, 15, 15.
Camera as narrator. Close = intimate. Pulling back = revealing scope. Rising = transcendence. Returning = closure. The Simultaneity pull-back (z=26 → z=61, y=0 → y=8) is a crane shot revealing cosmic scale. Name your camera movements as if directing a film.

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.
- 8d ago First seen · 461 lines · 158 tokens per session scan A d490b63fc3a3
threejs-particle-canvas is a skill published in the GitHub repository tdimino/claude-code-minoan (41 stars, last pushed yesterday), licensed MIT. It adds 158 tokens to every session and 7,049 once invoked, about $0.0008 per session on Opus 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.
