What it does, in the publisher's words

Configure and use EAS Update for over-the-air JavaScript and asset updates with expo-updates and EAS CLI. Use when setting up OTA updates, running eas update:configure or eas update, publishing to preview/staging/production channels, explaining branches/channels/runtime versions, testing updates, or debugging why an installed build still shows old code.

The description field of the SKILL.md. The agent reads only this at startup and decides from it when to load the full skill.

Install EAS Update

The skills CLI copies the skill into the folder of each agent you pick (Claude Code, Codex, Cursor, Copilot, Gemini CLI, OpenCode, Windsurf...). Add -g for all projects. Needs Node.js 22.20+. docs

npx skills add expo/skills --skill eas-update

This repo is a plugin marketplace. Inside Claude Code, add it and install the plugin that holds the skill (expo, expo-experiments), or copy only this skill into ~/.claude/skills. docs

/plugin marketplace add expo/skills
/plugin install <plugin>@expo-plugins

# or only this skill:
npx skills add expo/skills --skill eas-update -a claude-code

Download the skill folder, zip it, then Customize > Skills > + > Create skill > Upload a skill. Code execution must be on (Settings > Capabilities). docs

git clone --depth 1 https://github.com/expo/skills.git /tmp/eas-update-src
cp -r /tmp/eas-update-src/plugins/expo/skills/eas-update ./eas-update
zip -r eas-update.zip eas-update

Codex reads skills from .agents/skills in the repo or ~/.agents/skills. Type $ in Codex to use one. docs

npx skills add expo/skills --skill eas-update -a codex

gh skill (GitHub CLI 2.90+, preview) installs it for Copilot in VS Code, the CLI and the cloud agent. Copilot also reads .github/skills and ~/.copilot/skills. docs

gh skill install expo/skills eas-update

Cursor reads .cursor/skills, .agents/skills and ~/.cursor/skills (and .claude/skills). It does not install loose skills from a GitHub URL, so copy it in. docs

npx skills add expo/skills --skill eas-update -a cursor

Installs from the GitHub repo; --path picks this skill out of the repo. Default scope is user (all projects). docs

gemini skills install https://github.com/expo/skills.git --path plugins/expo/skills/eas-update

OpenCode reads .opencode/skills, ~/.config/opencode/skills and the Claude and .agents folders. docs

npx skills add expo/skills --skill eas-update -a opencode

Windsurf (now Devin Desktop) reads .devin/skills, .windsurf/skills and ~/.codeium/windsurf/skills. docs

npx skills add expo/skills --skill eas-update -a windsurf

Works with

Claude Code, Claude.ai and Claude Desktop, Codex, GitHub Copilot, Cursor, Gemini CLI, OpenCode, Windsurf and other agents that read the open Agent Skills format.

Pre-approves these tools (allowed-tools, experimental in the spec): Bash(npx expo *), Bash(npx *eas-cli@*), Bash(eas *).
