What is expo-react-native-repo-dev?

A repository-specific workflow for building the mobile app in an Expo and React Native monorepo, meaning one repository containing multiple packages. It covers the app in packages/mobile, its navigation, mobile device behavior, and related configuration.

Building or updating mobile screens, navigation, safe areas, gestures, deep links, offline sync, authentication restore, camera and QR features, and Expo build profiles.

It tells an agent when this workflow applies and records the project’s fixed mobile-app rules. That reduces the risk of changing the wrong package or breaking the established Expo setup.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00068	$0.01269
Opus 5.5	$0.00027	$0.00508
Sonnet 5.5	$0.00014	$0.00254

Security

Grade A, and why

expo-react-native-repo-dev 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 2mo 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.

Expo React Native Repo Dev

Use this skill when the task is about building the mobile app in this workspace, not generic React Native advice.

When to Use

Use when the request mentions any of these terms:

Expo, React Native, or packages/mobile
Expo Router routes, app shell, navigation, or screen structure
iOS or Android behavior
safe area, gestures, transitions, or mobile layout work
deep links, QR entry, or app scheme handling
offline sync, auth restore, or local draft flows
camera, document capture, media handling, or QR scanning
app.config.ts, eas.json, package.json, or Expo profile changes
repo-specific mobile commands, monorepo behavior, or pnpm filters

Current Repo Contract

Treat these as hard constraints unless the user explicitly changes them:

the Expo app lives at packages/mobile
the package name is @kanban-lite/mobile
the stack is Expo SDK 55 + Expo Router
the root layout already uses SafeAreaProvider in packages/mobile/app/_layout.jsx
packages/mobile/app.config.ts owns the app scheme and variant-specific native identifiers
packages/mobile/eas.json defines development, preview, and production profiles
the mobile app must not import the Node-only kanban-lite/sdk runtime at runtime
mobile code should talk to Kanban Lite through REST and mobile-local client modules
the repo currently prefers lint + Expo validation over package-local TypeScript gating because React type majors differ across workspaces

Procedure

Start from the repo entry points.
- Check packages/mobile/package.json for the supported scripts.
- Check packages/mobile/app.config.ts before touching bundle identifiers, scheme, or variant logic.
- Check packages/mobile/eas.json before changing preview or release behavior.
- Check the mobile docs in docs/ when the change touches auth, offline sync, deep links, checklist actions, or visibility.
Keep the runtime boundary clean.
- Do not import kanban-lite/sdk into Expo runtime code.
- Prefer transport-safe DTOs, REST payloads, or mobile-local modules under packages/mobile/src/** as the app grows.
- If shared logic is needed, make sure it is browser/mobile-safe rather than Node-runtime-specific.

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.
