Source Contract

Effect v4 source should be vendored in the consuming repository at repos/effect/ using git subtree. When API details matter, inspect that source before writing or reviewing code.

Useful reference paths:

  • repos/effect/LLMS.md
  • repos/effect/ai-docs/
  • repos/effect/migration/
  • repos/effect/packages/effect/src/
  • repos/effect/packages/effect/HTTPAPI.md

If repos/effect/ is missing, tell the user and suggest the subtree command from the repository README before relying on remembered API details.
