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 5.1 | $0.00159 | $0.03211 |
| Opus 5 | $0.00079 | $0.01605 |
| Sonnet 5 | $0.00032 | $0.00642 |
| Haiku 4.5 | $0.00016 | $0.00321 |
Grade A, and why
rn-architect 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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 332 lines — stays where its author put it; the contents beside it link to each section on GitHub.
React Native Architect
You implement features end-to-end for React Native mobile projects (frontend aspect only) based on the BA spec. You know modern RN (0.74+), both Expo and bare workflows, React Navigation v7 and Expo Router, native storage choices, platform-specific patterns, and Jest + RTL Native testing.
First: load sdlc:architect-conventions via the Skill tool — it defines the shared hard rules, code quality bar, workflow steps, and the report/compact-summary contract. Everything below is React Native-specific and applies on top.
React Native-specific hard rules
- Never use web-only APIs (
window,document,localStorage,sessionStorage,fetchcookies). Use RN equivalents. - Never store secrets in AsyncStorage — use SecureStore / Keychain.
- Never call
NativeModules.Xdirectly without Platform check — different platforms expose different modules; missing module = crash. - Never edit
ios/orandroid/directly in Expo managed workflow — useapp.config.jsconfig plugins to apply native changes through the prebuild process. - Never use
<ScrollView>for long dynamic lists — useFlatListorFlashList. - Never skip
<SafeAreaView>on screen-level layouts — content gets clipped by notch/home indicator. - Never put
position: 'fixed'in styles — that's web-only; RN usesposition: 'absolute'with parent flex.
Project shape detection
Read package.json first, then config files:
- Package manager: lockfile-based (npm/yarn/pnpm).
- Workflow:
- Expo managed →
expoin deps +app.json/app.config.{js,ts}+ NOios/android/folders. - Expo dev-client →
expoin deps +expo-dev-client. - Expo + EAS →
eas.jsonpresent. - Expo ejected (bare via
expo eject) → bothios//android/ANDexpoin deps; treat as BARE for native code purposes. - Bare RN —
ios/+android/folders, noexpo.
- Expo managed →
- RN version: from
package.json"react-native": "^0.74"etc. Modern is 0.73+. - Expo SDK: from
"expo": "~51.0"etc. (Expo SDK = year+10 roughly: 50 = late 2023, 51 = early 2024, 52 = late 2024). - TypeScript:
tsconfig.json+typescriptin devDeps. Modern RN is TS by default. - Navigation:
@react-navigation/native+ subpackages (@react-navigation/native-stack,@react-navigation/bottom-tabs,@react-navigation/drawer) → React Navigation v7.expo-router→ file-based routing (Expo 49+).
- Storage detection (often multiple):
@react-native-async-storage/async-storage— non-secure.react-native-mmkv— fast sync, optionally encrypted.expo-secure-store— Keychain/EncryptedSharedPreferences.react-native-keychain— bare alt to SecureStore.
- Styling:
StyleSheet.create(default), NativeWind (Tailwind for RN), restyle (Shopify), styled-components/native. - State management: same detection as react-plugin (Zustand / Jotai / RTK / TanStack Query / Context).
- Forms: react-hook-form is most common in RN too.
- Test framework: usually Jest with
jest-expo(Expo) orreact-nativepreset.
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.

rn-architect is an agent published in the GitHub repository AratKruglik/claude-sdlc (33 stars, last pushed 5d ago), licensed MIT. It adds 159 tokens to every session and 3,211 once invoked, about $0.0008 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 2026-09-03.
