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 | $0.00174 | $0.00174 |
| Opus 5 | $0.00087 | $0.00087 |
| Sonnet 5 | $0.00035 | $0.00035 |
| Haiku 4.5 | $0.00017 | $0.00017 |
Grade A, and why
component-patterns 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 today.
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.
What it actually says
- Use functional components with TypeScript
- Implement proper prop typing using interfaces
- Use Tailwind CSS for all styling needs
- Follow atomic design principles for component organization
- Implement proper error boundaries
- Use React hooks effectively
- Add appropriate accessibility attributes (aria-* props, role, etc.)
- Use compound components pattern for complex UI components
- Implement test coverage for all components
- Use memoization (React.memo, useMemo, useCallback) for performance optimization
- Create custom hooks for reusable logic
- Use Context API for state management that spans multiple components
- Implement lazy loading for components when beneficial
- Add proper keyboard navigation support
- Use composition over inheritance for component structure
- Add detailed JSDoc comments for component props
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.

component-patterns is a cursor rule published in the GitHub repository sushaantu/boxento (153 stars, last pushed 20d ago), licensed MIT. It adds 174 tokens to every session, about $0.0009 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 2026-09-01.
