Effect Schema

Use this skill for effect/Schema modeling, tagged errors, and beta compatibility.

Current Compatibility Note

This repo tests with alchemy@2.0.0-beta.59 and effect@4.0.0-beta.84, while accepting stable Effect 4 through the peer dependency range.

Rules

• Treat schemas as Schema<Type, Encoded, Requirements>.
• Decode untrusted API/config data at boundaries.
• Prefer tagged errors for provider failures that callers may handle.
• Keep TypeScript types and runtime validation aligned.
• Verify exact Schema APIs against docs/source when changing Effect versions.

• Effect Schema docs: https://effect.website/docs/schema/introduction/
• Effect changelog/source for beta compatibility.
• Alchemy Auth/AuthProvider.ts for the dependency-pin issue.
