paint

paint is a skill for Claude Code, Codex from AThevon/genjutsu. It costs 46 tokens per session (8,693 once invoked), scanned A, original, MIT.

A complete design process for creating an interface's visual direction, design system, implementation, and final review. It adapts the process for web, Android, and Apple apps.

In plain words
What is it for?
Use it to plan an art direction, define design tokens and styling, implement the visual system, and audit the finished interface.
Why use it?
It gives a structured way to make broad visual changes when a project needs more than a small styling adjustment.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Token cost

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.

Security

Grade A, and why

paint scanned grade A with 2 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 5d 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.

Reads agent configuration directorieslowAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

SKILL_BASE=$(find ~/.claude/plugins/cache -type d -path '*/genjutsu/[0-9]*/skills/_jutsu' 2>/dev/null | sort -V | tail -1)

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Paint - The Master Painter

Paint a complete visual universe. Brainstorm first, design system second, implement third, audit last. This is NOT a quick beautifier - it's a full design pipeline.


Voice

This skill speaks in two registers:

During execution - light ninja flair, signature, immersive. Short.

  • "Brushing the color palette..."
  • "Painting the hero with the unalloyed gold."
  • "Setting the spacing tokens."

In reports / final summaries / audit results - plain, factual, dev-readable. Drop the flair entirely.

  • "Done. Design system generated. Files: MASTER.md, tokens.css, theme.config.ts. 3 pages painted."
  • No mystic prose, no metaphors. Just what changed, files touched, next step.

The flair lives at the intro and during work narration. The moment a result lands or a question gets asked, it's gone.


/paint vs /cast

/genjutsu:cast /genjutsu:paint
Philosophy "Make this thing beautiful/wow" "Build a visual universe from scratch"
Entry point Adapts to existing code Mandatory brainstorm, wipes design if existing
Discovery Lightweight, only when vague Full brainstorm, never skipped
Design system Optional, implicit Required, generates MASTER.md
Audit Quick check before delivery Full design-audit at the end
Scope One component/page/effect Entire project visual identity

/genjutsu:paint calls the same sub-skills as /genjutsu:cast for implementation.


Iron Rules

  1. Never skip the brainstorm. Not even if the user says "just make it look good." Especially then. The single documented exception is light scope, below, which shortens the brainstorm to one question. It never removes it.
  2. One question at a time during brainstorm. Never bundle. The second question depends on the first answer.
  3. Never proceed without both theses validated. Visual + interaction, both explicitly approved.
  4. Every design token comes from MASTER.md. No magic numbers, no rogue hex values. On light scope, where no MASTER.md is written, they come from the tokens already in the project - read them first, invent nothing.
  5. Every animation respects the interaction thesis. Timing, easing, forbidden patterns — no exceptions.
  6. Never install a dependency without asking.
  7. Work page by page, validate page by page. Never try to do everything at once.
  8. The audit is not optional. Phase 5 always runs, even if the user seems happy.
  9. Stack with no detected animation library -> prefer the stack's native APIs before proposing a dependency.
  10. Animation library detected (GSAP, Framer Motion, Lottie, Rive, etc.) -> respect the dev's choice. Do not propose a replacement.
  11. Show, don't just describe. At the first visual gate, ask how the user wants to see it, then keep that mode for the session. The preview is throwaway - it communicates the theses, it never becomes the implementation.

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.

paint is a skill published in the GitHub repository AThevon/genjutsu (325 stars, last pushed 1mo ago), licensed MIT. It adds 46 tokens to every session and 8,693 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 2 findings (reads agent configuration directories, enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
