Skills Reference

Skills Reference — Everything Claude Code Draws On

A reference, not a lesson. You don't need to memorize this — Claude Code picks the right skill automatically based on what you ask. This is here so you know what exists and what it's for.

"Skill" = a pre-built expertise pack that teaches Claude Code a specific process, so it doesn't have to be re-explained every session.

Part 1 — Installed skills (official expo/skills plugin)

Installed once via /plugin install expo@expo-plugins — see skills/README.md in this repo's root for reinstall instructions.

| Skill | What it does | |---|---| | expo-router | File-based navigation, project structure conventions | | expo-native-ui | UI component patterns | | expo-data-fetching | Data/API patterns | | eas-app-stores | EAS Build/Submit mechanics | | eas-workflows | CI automation via EAS Workflows |

Part 2 — Local skills (this system's skills/local/)

Forked/adapted from rahulkeerthi/expo-toolkit plus this system's own additions.

| Skill | Used in | What it does | |---|---|---| | expo-scaffolding | Phase 2 | Project genesis conventions (Zustand, folder structure) | | monetization | Phase 6 | RevenueCat (IAP/subscriptions) + react-native-google-mobile-ads integration | | eas-build-and-submit | Phase 8 | Build profiles, cloud-managed Apple credentials, eas submit mechanics, cost-timing rule | | screenshot-capture | Phase 9 | EAS/Maestro Cloud device capture + compositing to App Store dimensions |

Part 3 — Shared skills (referenced from the native iOS app builder system repo, not duplicated)

These don't depend on implementation stack — market research, ASO, and growth strategy work the same whether the app is Swift or React Native.

| Skill | Used in | |---|---| | app-research (native repo: ios-app-research) | Phase 1 | | asset-prompts (native repo: ios-asset-prompts) | Phase 3 | | pricing, paywalls, marketing-psychology | Phase 6 (before code) | | app-store-guidelines-compliance (policy content only — see this repo's review-gate agent for RN-specific technical checks) | Phase 7 | | asc-metadata-sync, asc-release-flow, asc-submission-health, asc-whats-new-writer, asc-id-resolver | Phase 9 | | Full GROW-arc stack (phases 10-16) | See the native repo's 05-skills-reference.md Part 3 for the complete list — every skill there applies unchanged here |

Part 4 — The memory system

| Component | What it does | |---|---| | wiki/ + CLAUDE.md | This system's own knowledge vault — not shared with the native system's | | .claude/agents/arc-phase-manager.md | Reads this system's wiki, tells you which phase an app is in | | .claude/agents/review-gate.md | RN-specific pre-submission blocker — greenfield, no native-system equivalent to copy |

Part 5 — External tools (not skills)

| Tool | What it's for | |---|---| | EAS CLI | Cloud build + submit — the entire reason this system needs no Mac | | Expo Go | Live-preview the app on a physical iPhone via QR code — no simulator needed | | Maestro / Maestro Cloud | Automated UI testing — cloud mode needs no local device or infra | | GitHub | Version control, EAS build triggers |
