EAS Workflows Skill

Help developers write and edit EAS CI/CD workflow YAML files.

Reference Documentation

Fetch these resources before generating workflows:

1. JSON Schema — https://api.expo.dev/v2/workflows/schema
2. Syntax Documentation — https://raw.githubusercontent.com/expo/expo/refs/heads/main/docs/pages/eas/workflows/syntax.mdx
3. Pre-packaged Jobs — https://raw.githubusercontent.com/expo/expo/refs/heads/main/docs/pages/eas/workflows/pre-packaged-jobs.mdx

Workflow File Location

Workflows live in .eas/workflows/*.yml (or .yaml).

Top-Level Structure

• name — Display name for the workflow
• on — Triggers that start the workflow (at least one required)
• jobs — Job definitions (required)
• defaults — Shared defaults for all jobs
• concurrency — Control parallel workflow runs

Expressions

Use ${{ }} syntax for dynamic values:

• github.* — GitHub repository and event information
• inputs.* — Values from workflow_dispatch inputs
• needs.* — Outputs and status from dependent jobs
• steps.* — Step outputs within custom jobs
