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 | $0.00021 | $0.00414 |
| Opus 5.5 | $0.00008 | $0.00166 |
| Sonnet 5.5 | $0.00004 | $0.00083 |
| Haiku 4.5 | $0.00002 | $0.00041 |
Grade A, and why
erne-native-module 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 8d 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
/erne-native-module — Create Native Module
You are executing the /erne-native-module command. Run native-bridge-builder first (create the module), then code-reviewer (review it). This is sequential, not parallel.
Phase 1: native-bridge-builder — Scaffold & Implement
Determine Module Type
Ask the user or detect from project:
- Expo Modules API — For Expo managed projects (recommended)
- Turbo Module — For bare React Native projects (New Architecture)
- Fabric Component — For custom native views
Scaffold the Module
Generate all required files based on module type:
Expo Module (6 files):
modules/[module-name]/
expo-module.config.json # Module configuration
src/[ModuleName]Module.ts # TypeScript API definition
ios/[ModuleName]Module.swift # Swift implementation
android/src/main/java/.../[ModuleName]Module.kt # Kotlin implementation
src/__tests__/[ModuleName].test.ts # Unit tests
README.md # Usage documentation
Implementation Guidelines
- Define clear TypeScript interface first (contract)
- Implement Swift and Kotlin to match the contract
- Handle errors consistently (reject Promises with error codes)
- Use
async/awaitin Swift, coroutines in Kotlin - Include JSDoc comments on the TypeScript API
Phase 2: code-reviewer — Review the Module
After module creation, automatically run code review:
- Verify TypeScript types match native implementations
- Check error handling on both platforms
- Validate threading (no main thread blocking)
- Review memory management (cleanup, listeners)
- Check platform parity (same behavior iOS/Android)
Output
- Scaffolded module files with implementation
- Code review results
- Usage example in React Native
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.

erne-native-module is a command published in the GitHub repository JubaKitiashvili/everything-react-native-expo (49 stars, last pushed 9d ago), licensed MIT. It adds 21 tokens to every session and 414 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-09.
