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 | $0.00082 | $0.01211 |
| Opus 5 | $0.00041 | $0.00606 |
| Sonnet 5 | $0.00016 | $0.00242 |
| Haiku 4.5 | $0.00008 | $0.00121 |
Grade A, and why
trove-react-native 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.

Trove · v2026.7.4
Session Init
This skill ships Trove conventions. Prefer existing project patterns over generic best practices when they conflict.
React Native Skills
Best practices for React Native and Expo applications, organized by impact. Each rule has a detailed reference file under references/ with incorrect/correct code examples.
When to Apply
- Building React Native or Expo apps
- Optimizing list and scroll performance (FlashList, virtualization)
- Implementing animations with Reanimated and Gesture Handler
- Working with images and media (expo-image, Galeria)
- Configuring native modules, custom fonts, or platform integrations
- Structuring monorepo projects with native dependencies
Note: This skill is user-invocable rather than glob-auto-attached, since React Native projects are less common than web React ones — invoke it explicitly for ad-hoc RN work or new projects.
Rule Categories by Priority
| Priority | Category | Impact | Prefix |
|---|---|---|---|
| 1 | List Performance | CRITICAL | list-performance- |
| 2 | Animation | HIGH | animation- |
| 3 | Navigation | HIGH | navigation- |
| 4 | UI Patterns | HIGH | ui- |
| 5 | State Management | MEDIUM | react-state- |
| 6 | Rendering | MEDIUM | rendering- |
| 7 | Monorepo | MEDIUM | monorepo- |
| 8 | Configuration | LOW | fonts-, imports- |
Quick Reference
1. List Performance (CRITICAL)
list-performance-virtualize— Use FlashList for large listslist-performance-item-memo— Memoize list item componentslist-performance-callbacks— Stabilize callback referenceslist-performance-inline-objects— Avoid inline style objectslist-performance-function-references— Extract functions outside renderlist-performance-images— Optimize images in listslist-performance-item-expensive— Move expensive work outside itemslist-performance-item-types— Use item types for heterogeneous lists

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.

trove-react-native is a skill published in the GitHub repository bravew/trove (10 stars, last pushed 4d ago), licensed MIT. It adds 82 tokens to every session and 1,211 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 2026-08-31.
