expo/skills

If your AI coding agent writes plausible React Native code but gets Expo Router structure, EAS workflows or SDK upgrades subtly wrong, these official skills are worth installing before the next app task. They are documentation-shaped guidance for the agent, not a runtime library.

The problem

You ask an agent to add native tabs and a modal to an Expo app, or to wire a preview build on pull requests. Without Expo-specific context, it improvises folder layouts, mixing routes and screens, or invents EAS configuration that does not match current conventions. You then spend the session correcting structure and looking up the Expo docs yourself. Installing the skills changes the agent's starting context: it can pick the relevant skill from the task and apply Expo's documented patterns to the files it edits. The result is a first draft that follows Expo conventions rather than a generic React Native guess.

What's different

This is a curated set of SKILL.md instructions rather than a code generator. An expo-overview entry point routes vague requests to narrower skills covering project structure, Expo Router navigation, animation, native UI, design systems, data fetching, DOM components, web-to-native migration, native modules and brownfield integration. A second group targets EAS: store builds and submissions, hosting, workflows, Observe metrics, Update rollouts and remote simulators. Each skill carries enough context for an agent to choose it, and the services group is explicitly labelled as paid, with a costs and plan-limits note at the top of each such skill.

The README is careful about authority: Expo documentation, the Expo CLI and the EAS CLI remain the source of truth, and the skills are meant to help agents apply that guidance. That matters because skills are instructions, not enforcement — an agent can still deviate, and nothing in the repository validates the code it writes. The split between free framework skills and paid services skills is also a design choice worth noticing: installing everything gives agents knowledge of paid EAS features that will not work without an account and plan.

Who should try it

Good fit: a developer already using Claude Code, Codex, Cursor or another listed agent on an Expo or React Native project, especially one frequently asking for Router screens, SDK upgrades or EAS build/update configuration. The skills reduce repeated explanation of Expo conventions and are official, so they should track the documented API surface.

Poor fit: someone who wants a scaffolder or a running app generator, or who does not use an AI coding agent at all — installing these changes nothing about the project itself. Teams without an EAS plan should read the services group as reference only, since those skills depend on paid Expo Application Services. The README lists many supported agents and the plugin path keeps Claude Code and Codex installs updated through official marketplaces project instructions.

Requirements and limitations

You need an AI coding agent that can discover installed skill files, and for most agents that means the skills CLI from the project root followed by a session restart or refresh skills CLI documentation. Claude Code and Codex users can take the plugin route instead, which routes updates through their official marketplaces; choosing the CLI means you later run the update command yourself, per skill or for all of them. The two paths differ in who handles upkeep, not just in command syntax.

Ongoing care has two parts. Framework skills follow open-source Expo SDK changes, while services skills describe paid EAS behavior and can go stale as plans, limits or APIs change. Keep the plugin versions current and treat the skills' advice as guidance to check against Expo docs, not as an authoritative spec. The experimental expo-migrate-module skill ships separately in expo-experiments and may change or be retired project instructions.

HotRepo's take

HotRepo's only recorded observation is 2026-10-28, when the repository appeared on the daily board at 3,338 stars with +212 that day; with a single dated sample, persistence of interest cannot be judged project overview. The practical question is narrower than star count: confirm the skill catalog covers your current Expo SDK version before relying on the upgrade skill, since mismatched guidance is the most likely way this ages poorly.
