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.

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 | $0.00046 | $0.08693 |
| Opus 5 | $0.00023 | $0.04346 |
| Sonnet 5 | $0.00009 | $0.01739 |
| Haiku 4.5 | $0.00005 | $0.00869 |
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.

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
- 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.
- One question at a time during brainstorm. Never bundle. The second question depends on the first answer.
- Never proceed without both theses validated. Visual + interaction, both explicitly approved.
- 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.
- Every animation respects the interaction thesis. Timing, easing, forbidden patterns — no exceptions.
- Never install a dependency without asking.
- Work page by page, validate page by page. Never try to do everything at once.
- The audit is not optional. Phase 5 always runs, even if the user seems happy.
- Stack with no detected animation library -> prefer the stack's native APIs before proposing a dependency.
- Animation library detected (GSAP, Framer Motion, Lottie, Rive, etc.) -> respect the dev's choice. Do not propose a replacement.
- 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.

component-family-consistency
Buttons, inputs, pills, badges, calendars, and other interactive components form a visual family — they share the same border-radius, colour logic, shadow scale, border style, and spacing rhythm. Inconsistency between them breaks the sense of a coherent product. Use when building or reviewing a component library…
extract-design
Extract a complete design system — colors, typography, spacing, components, shadows, and W3C design tokens — from any live website using Dembrandt. Runs a headless browser against the URL and returns real computed values from the DOM. Use when you need a site's actual design tokens, want to reverse-engineer a visual…
algorithmic-color-palette
Derive a full UI colour palette algorithmically from one or two brand colours. Darker and lighter variants for interactive states, desaturated greys from the brand hue for borders and backgrounds, and semantic colours that feel coherent with the brand rather than generic. Use when building a colour system from scratch…
brand-visual-language
A brand's visual tone — playful or serious, rounded or angular — should be consistent across all UI elements. Shape language in typography, border-radius, and iconography communicates personality before a single word is read. Use when establishing a design system, choosing icon libraries, setting border-radius tokens…
data-display-and-selection
Complex data deserves multiple view modes — grid, list, table — chosen by the user based on their task. Row and item selection should use large hit areas (the whole row or card, not just a checkbox). Selected state is communicated through a subtle background colour shift. Mass actions appear when items are selected.…
generate-ui-from-brand
Pipeline skill — turns a URL or DESIGN.md into a concrete UI structure with decisions already made. Extracts live design tokens, normalizes them into a semantic system, applies UX principles, and outputs an actionable UI spec. Use when building UI for an existing brand from scratch, auditing a design system, or…
