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 4 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 | $0.00119 | $0.01458 |
| Opus 5 | $0.00060 | $0.00729 |
| Sonnet 5 | $0.00024 | $0.00292 |
| Haiku 4.5 | $0.00012 | $0.00146 |
Grade A, and why
paper-design 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 10d 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 — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Read and write designs in Paper via MCP. Paper is a DOM-based design tool — designs are HTML/CSS structures that Claude reads and writes natively.
Prerequisites
Paper Desktop must be running before starting Claude Code. The app auto-starts an MCP server at http://127.0.0.1:29979/mcp. Run python3 ~/.claude/skills/paper-design/scripts/health-check.py to verify connection. If the MCP server is not registered, run bash ~/.claude/skills/paper-design/scripts/setup.sh.
Paper vs Pencil
Use Paper for design-to-code, code-to-design, and rapid prototyping (native DOM). Use Pencil for reusable design systems, existing .pen files, and presentations. Full comparison: references/paper-vs-pencil.md
Paper Shaders
Paper also ships a standalone React shader library — @paper-design/shaders-react — used independently of the MCP workflow. Install with npm i @paper-design/shaders-react and import named components like MeshGradient, FlutedGlass, LiquidMetal, HalftoneCMYK, GodRays. 30+ shaders across three categories (Image Filters, Logo Animations, Effects). Zero dependencies beyond React.
Reach for Paper Shaders when the goal is to use a designer-tuned effect as a React component with named props. Reach for threejs-particle-canvas, grainient, or rocaille-shader when the goal is custom particle systems, grainient.supply-style page aesthetics, or pointer-reactive DOM distortion — those skills have different strengths. Shaders authored in Paper-the-tool export as the matching React component via get_jsx; prop names map 1:1 onto the sliders in each shader panel.
Full catalog, per-category tables, and integration notes: references/shaders.md.
Workflow
Every Paper interaction follows four phases: Orient, Create, Verify, Export.
1. Orient
Read document state before making changes. Call get_basic_info for file name, page name, artboard list. Call get_tree_summary with an optional depth limit for structure overview. Call get_selection when the user says "this element" or "the selected thing."
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

paper-design is a skill published in the GitHub repository tdimino/claude-code-minoan (41 stars, last pushed 2d ago), licensed MIT. It adds 119 tokens to every session and 1,458 once invoked, about $0.0006 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 2026-08-30.
