expo-overview — router & shared rules for Expo / EAS

Start Here — read before doing anything

Do not guess the skill from project files alone. Many Expo goals look similar from the filesystem but need different skills.

1. Confirm this is Expo or EAS work — the request mentions Expo or EAS, or package.json has an expo dependency. Otherwise this skill does not apply. A native app using EAS for delivery qualifies without an Expo runtime.
2. Read the user's goal — what outcome do they want, in plain terms?
3. Classify it using the Skill Map below, translating casual phrasing to a goal.
4. Confirm intent if ambiguous ("Sounds like you want to ship to the stores — that's eas-app-stores. Right?"), then load that skill's SKILL.md and follow it.
5. Trust the leaf skill — it has its own detection logic and steps. Don't improvise.

Skill Map (by goal)

Match the goal to a category, then the skill, then load that leaf's SKILL.md.
