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 | $0.00075 | $0.00733 |
| Opus 5 | $0.00037 | $0.00367 |
| Sonnet 5 | $0.00015 | $0.00147 |
| Haiku 4.5 | $0.00007 | $0.00073 |
Grade A, and why
reviewing-rn-code 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 4d 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.

Reviewing React Native Code
Severity levels
- NON-NEGOTIABLE: Blocks merge. No exceptions.
- CRITICAL: Must fix before merge.
- SUGGESTION: Should fix.
Review process
- Read all files in the feature being reviewed
- Check against non-negotiable rules in rules/mobile-rules.md
- Check permission coverage using the
permission-guidelinesskill - Check for common issues in references/rn-common-issues.md
- Output findings
Non-negotiable checks
- 3-file split compliance (hook/view/glue)
- View file contains ZERO hooks
- Hook return type === View props type
- FlatList for lists, not ScrollView + .map()
- NativeWind className (not inline styles or StyleSheet in views)
- No web APIs (localStorage, window, document)
- SafeAreaView on screen roots
- KeyboardAwareScrollView (from react-native-keyboard-controller) on form screens — NOT KeyboardAvoidingView
- Typed navigation params
- accessibilityLabel on all interactive elements
- Permission gating with useCan
React Native Reusables checks
- UI components from
@/components/ui/, not manual implementations -
<Text>from@/components/ui/textfor all text (never bare strings) -
<Button>has<Text>child (RN Button requires explicit Text) - PortalHost in root layout (if using Dialog, DropdownMenu, Select, Tooltip, Popover)
- Label uses
nativeID(nothtmlFor) for form association - Input uses
aria-labelledbyto connect to Label - Theme tokens from NativeWind (
bg-background,text-foreground) — not hardcoded colors
Performance checks
- React.memo on FlatList renderItem components
- Image caching (react-native-fast-image or expo-image)
- No large inline objects in JSX (forces re-renders)
- No unnecessary re-renders from unstable references
- Reanimated used for complex animations (not Animated API)

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

reviewing-rn-code is a skill published in the GitHub repository narpatsinghpurohit/tstack (5 stars, last pushed 5mo ago), licensed MIT. It adds 75 tokens to every session and 733 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.
