primitives AGENTS.md

A short instruction file for agents working on Radix NG Primitives, with rules for styling its Storybook component examples.

In plain words
What is it for?
Use it when creating or editing Storybook stories and component demonstrations in the Radix NG Primitives project.
Why use it?
It prevents inconsistent demos by specifying which Tailwind classes, design tokens, and shared demo shell to use, and when to ask before adding CSS.

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

primitives AGENTS.md 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 3d 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.

Agent Guide

Storybook Styling

  • Use Tailwind v4 utilities directly in story templates and standalone story components.
  • Do not add story-local CSS files, Angular styleUrl / styleUrls / styles, inline <style> blocks, or style="..." attributes.
  • Use semantic tokens such as bg-background, text-foreground, bg-muted, border-border, and text-primary-foreground.
  • Use packages/primitives/storybook/tailwind-demo.ts for the shared Storybook demo shell.
  • If a demo cannot reasonably be expressed with Tailwind utilities, explain why and ask before adding CSS.
Changes

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.
