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.

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 | $0.00078 | $0.01285 |
| Opus 5 | $0.00039 | $0.00642 |
| Sonnet 5 | $0.00016 | $0.00257 |
| Haiku 4.5 | $0.00008 | $0.00128 |
Grade A, and why
nap-design-system 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 9d 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
NAP Design System
NAP's web UI is React + Vite + TailwindCSS (v3) + shadcn/ui, themed by the
shared @neutree-ai/theme package. Every color is a semantic OKLCH token, not
a raw Tailwind palette color. Follow this skill to produce UI that matches the
existing app instead of generic AI-looking output.
How to use this skill
- Read this file for the hard rules and the quick reference.
- Read
references/tokens.mdbefore choosing any color. - Read
references/components.mdbefore hand-rolling a control — a shadcn component or variant almost certainly already exists. - Read
references/patterns.mdfor surfaces, glass panels, icons, dark mode, typography, and the recurring layout conventions.
The hard rules (do not violate)
- Colors must be semantic tokens. Use
bg-card,text-muted-foreground,border-border,bg-primary,text-warning, etc. Never raw palette colors (bg-slate-800,text-blue-500,#1e293b) and never inlinestyle={{ color: ... }}. Tokens carry light/dark automatically; raw colors break dark mode and the theme. - Icons are
lucide-react, never emoji. Emoji must never stand in for an icon. Import the named icon component (import { Plus } from "lucide-react"). - No unilateral component swaps. Reuse
@/components/ui/*; don't pull in a new UI library or reinvent a button/dialog/tooltip that already exists. - Compose classes with
cn()from@/lib/utils(clsx + a customized tailwind-merge) so overrides merge correctly. Don't string-concatenate classes. - Tune opacity, not hue. Need a softer/stronger shade of a token? Use the
alpha modifier:
bg-primary/90,bg-success/15,border-info/30. Don't reach for a different palette color. - Polish in place. When you add a region, finish it to production quality (spacing, states, dark mode) rather than leaving a rough draft.
Token quick reference
Semantic roles (each has a -foreground pair where text sits on it):
What ships with it
3 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.

nap-design-system is a skill published in the GitHub repository neutree-ai/agent-platform (63 stars, last pushed today), licensed Apache-2.0. It adds 78 tokens to every session and 1,285 once invoked, about $0.0004 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.
