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 | $0.00026 | $0.00621 |
| Opus 5 | $0.00013 | $0.00311 |
| Sonnet 5 | $0.00005 | $0.00124 |
| Haiku 4.5 | $0.00003 | $0.00062 |
Grade A, and why
react-general 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.

General React & React Native Patterns
These rules apply to all files, including those inside src/mvvm/. See mvvm-architecture for MVVM-specific structure.
Component Architecture
- Prefer functional components.
- Keep components focused and reasonably sized.
- Decompose large UI into smaller reusable elements.
- Use composition for extensibility.
State Management
- Prioritize local state for UI-only concerns.
- Use RTK Query (with slices) only when necessary for app-wide state. See
rtk-query-api. - Apply optimized selectors to limit re-rendering.
- Connect Redux at the lowest component level when possible.
Styling
- Mobile: use Lumen UI React Native — see
ldls-native. - Desktop: use Lumen UI React — see
ldls-web. - All styles must support theme switching (dark/light mode).
Performance
- Memoize expensive operations with
useMemo. - Stabilize callbacks with
useCallback. - Wrap costly components in
React.memo. - Apply list virtualization where needed.
- Use lazy loading for large screens or modules.
Navigation
- Mobile: use React Navigation; ensure correct deep-link support; keep navigation types strict.
- Desktop: use React Router; implement route guards when necessary; maintain clear history logic.
Data Fetching
- Use RTK Query. See
rtk-query-api. - Use consistent loading, retry, and error states.
- Prefer optimistic UI when appropriate.
- Apply caching and stale-time strategies.
Accessibility
- Mobile: provide accessible labels for all interactive elements; support screen reader flows; ensure proper focus transitions.
- Desktop: use semantic HTML tags; implement full keyboard navigation; apply meaningful ARIA attributes when required.
Error Boundaries
- Wrap critical areas in error boundaries.
- Report errors to monitoring services.
- Provide clean, user-friendly fallback UIs.
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-general is a skill published in the GitHub repository LedgerHQ/ledger-live (614 stars, last pushed 3d ago), licensed MIT. It adds 26 tokens to every session and 621 once invoked, about $0.0001 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.
