expo_boilerplate CLAUDE.md is an instructions file for Claude Code from chohra-med/expo_boilerplate. It costs 782 tokens per session, scanned A, original, MIT.

Repository instructions for MobileLauncher LT, a React Native and Expo mobile app, including its branch rules and project-specific development guidance.

In plain words
What is it for?
Use them when changing, testing, branching, or preparing work for the expo_boilerplate mobile app and its related repository families.
Why use it?
They prevent agents from using the wrong branch or treating a development branch as a release branch.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is chohra-med/expo_boilerplate's own configuration. It tells Claude Code 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 CLAUDE.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 11d 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.

🌿 Branches — the trunk is development, there is NO main

This repo's trunk is development. It is the GitHub default branch and the base for every PR.

main does not exist here. gh api repos/chohra-med/expo_boilerplate/branches/main returns 404. Do not create it, do not target it, and do not assume it from habit. A PR opened against main cannot be merged because there is nothing to merge into.

⚠️ The estate is split by family — this is where the confusion comes from:

Family Trunk
The AI Mobile Launcher variants (Standard · AI · openSource), Morrow Self, Mane development
The getwireai repos (getwireai_website, wireai-onboarding-server, wireai-activation) main

So "merge to main" is correct advice for the getwireai repos and wrong for this one. Read the default branch rather than carrying a habit across families:

gh repo view --json defaultBranchRef -q .defaultBranchRef.name

A merge to development here is NOT a release. This is a React Native / Expo app: shipping to users requires a new native build, not a merge. Never report a merged PR as shipped.

A checkout is not its trunk. Local development drifts behind origin/development routinely. Base branches on origin/development and read trunk content with git show origin/development:<path>, never from the working tree.

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.
