expo_boilerplate: Instructions file for Codex

AGENTS.md

expo_boilerplate AGENTS.md is an instructions file for Codex, OpenCode from chohra-med/expo_boilerplate. It costs 345 tokens per session, scanned A, original, MIT.

Project instructions for an AI-first React Native and Expo mobile-app starter, with feature-based folders, strict TypeScript, Redux state management, and related development tools. They identify the .cursor/rules directory as the project's main source of coding rules.

In plain words
What is it for?
Use them when adding mobile features, components, navigation, Redux state, data fetching, styling, error handling, environment variables, accessibility, or tests in the Expo project.
Why use it?
They prevent agents from relying on incomplete duplicate instructions and help keep architecture, UI, navigation, state, testing, and best practices consistent.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md.

This is chohra-med/expo_boilerplate's own configuration. It tells Codex and OpenCode how to work on expo_boilerplate itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything expo_boilerplate configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

expo_boilerplate AGENTS.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 10d 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.

🎯 The Master Rules Location

CRITICAL INSTRUCTION: To prevent drift and inconsistency, the full, single-source-of-truth rules for this project reside in .cursor/rules/.

Before writing any new code, components, or making architectural decisions, you MUST read the contents of the following files based on the task context:

Topic Look in
Full Architecture & Feature-First Directory Structure .cursor/rules/app_feature_first_architecture.mdc
Code Standards, UI, Navigation, Redux, State & Testing .cursor/rules/app_rules.mdc
Advanced Best Practices (Error Handling, Env Vars, A11y) .cursor/rules/best_practices.mdc
Base Architecture Explanations ai_articles/memory-bank/

If you fail to observe these files, you risk producing legacy or hallucinated code that violates the stringent requirements of this architecture. Please use your ability to read local files to ingest these rules prior to generating code.

Changes

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.
