# Effect
Use current Effect v4 APIs and the production defaults in this skill. Established project conventions still take precedence unless the task is explicitly changing them.
## Source Rule
Reviewed against Effect **4.0.0**, upstream commit
[`6389d9ac6`](https://github.com/Effect-TS/effect/tree/6389d9ac64c0f62ccc8b575fb9afc65fc104e814).
Read `references/V4_APIS.md` when upgrading from v3 or a v4 prerelease.
The installed version takes precedence: prerelease APIs and import paths can differ.
Check these before guessing:
- the nearest `AGENTS.md` and any project-local Effect practices doc
