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 | $0.00006 | $0.00362 |
| Opus 5 | $0.00003 | $0.00181 |
| Sonnet 5 | $0.00001 | $0.00072 |
| Haiku 4.5 | $0.00001 | $0.00036 |
Grade A, and why
react 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 2d 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.
What it actually says
React
Frontend component library.
When To Use
- DOM components
- SPA framework
- Component-based UI
What To Do
1. Component Pattern
function MyComponent({ prop }) {
const [state, setState] = useState(null)
useEffect(() => {
// side effects
}, [])
return <div>{prop}</div>
}
2. Common Hooks
| Hook | What |
|---|---|
| useState | Local state |
| useEffect | Side effects |
| useContext | Shared state |
| useRef | DOM reference |
| useMemo | Memorized value |
| useCallback | Memorized function |
3. Patterns
// Conditional
{condition && <Component />}
// List
items.map(item => <Item key={item.id} {...item} />)
// Form
<form onSubmit={handleSubmit}>
<input value={value} onChange={e => setValue(e.target.value)} />
</form>
4. Testing
render(<MyComponent prop="value" />)
expect(screen.getByText('value')).toBeInTheDocument()
Output
## React
| Component | Tested | Status |
|------------|--------|--------|
| [name] | [YES/NO] | [OK] |

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.

react is a skill published in the GitHub repository dhaupin/vant (9 stars, last pushed 2d ago), licensed MIT. It adds 6 tokens to every session and 362 once invoked, about $0.0000 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 2026-08-31.
Other skills, from other repositories
commit
Atomic git commit with conventional message. Use when the user says "commit", "save my changes", "commit this", or wants to create a git commit. Stages specific files, writes a conventional commit message with body explaining non-obvious decisions. Never uses git add -A.
python-run
Run and debug Python scripts in the project. Use when the user says "run python", "execute this script", "debug this py file", or wants to run/modify a .py file. Handles dependency checks, linting, execution, and error analysis.
document-processor
Guidance for processing documents, extracting content, and transforming structured information. Use when the user asks to process, parse, extract, or transform document content such as PDFs, Word files, or spreadsheets.
skill-packager
Authors Agent Skills v1.0 packages (SKILL.md plus references/scripts), runs packageskill to produce a standards-compliant zip, and uses installskill to add skills from HTTPS, registry, workspace, or an uploaded archive. Use when the user wants to turn documentation, workflows, or code into a portable skill, export a…
workflow-helper
Guidance for creating, managing and executing workflow automations that chain multiple tools and agents together. Use when the user asks about building, listing, running or composing workflows and automated task pipelines.
attendance-signin-sheet
Generate printable attendance / 签到表 spreadsheets from name lists. Use when the user asks for 签到表, attendance sheet, meeting sign-in table, or similar printable roster tables (not full payroll attendance scoring unless asked).
