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 | $0.01441 | $0.01441 |
| Opus 5 | $0.00720 | $0.00720 |
| Sonnet 5 | $0.00288 | $0.00288 |
| Haiku 4.5 | $0.00144 | $0.00144 |
Grade A, and why
react-native-chat copilot-instructions.md 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.
How it starts
The opening of the file, as written. The whole thing — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.
React Native Chat
The most complete chat UI for React Native & Web. This is a TypeScript React Native component library with example applications demonstrating usage across React Native, React Native Web, and Expo platforms.
Always reference these instructions first and fallback to search or bash commands only when you encounter unexpected information that does not match the info here.
Working Effectively
Bootstrap and build the repository:
yarn install-- NEVER CANCEL: takes 58 seconds. Set timeout to 120+ seconds.yarn build-- builds TypeScript library, takes 3 seconds. Set timeout to 30+ seconds.yarn lint-- lints source code, takes 3 seconds. Currently has warnings but no errors. Set timeout to 30+ seconds.yarn test-- NEVER CANCEL: runs Jest test suite, takes 9 seconds. Set timeout to 60+ seconds.
Full validation before publishing:
yarn prepublishOnly-- NEVER CANCEL: runs lint + build + test, takes 11 seconds total. Set timeout to 60+ seconds.
Known Issues:
- If tests fail due to snapshot mismatches after fresh dependency install, run
yarn test -uto update snapshots - Snapshot tests may need updates when React Native or dependency versions change
Example app development:
cd example && yarn install-- NEVER CANCEL: takes 38 seconds. Set timeout to 90+ seconds.- Install Expo CLI globally:
npm install -g @expo/clior usenpx expocommands - Native development:
cd example && npx expo start - Web development:
cd example && npx expo start --web(requires additional dependencies) - The example app starts Metro bundler on http://localhost:8081
- Expect dependency version warnings in offline/CI mode - these are normal
Type checking and development:
yarn tsc:watch-- runs TypeScript compiler in watch mode for developmentyarn tsc:write-- compiles TypeScript and writes output to /lib directory
Requirements and Setup
System Requirements:
- Node.js >= 18 (tested with 20.19.4)
- Yarn package manager 1.22.22+ (do NOT use npm for this project)
- TypeScript compiler (included in devDependencies)
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-native-chat copilot-instructions.md is an instructions file published in the GitHub repository kesha-antonov/react-native-chat (48 stars, last pushed today), licensed MIT. It adds 1,441 tokens to every session, about $0.0072 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.
