Effect v4 is in RC. Point the install instructions at the rc dist-tag instead of beta.
Effect Skills
Agent skills for working effectively in repositories that use Effect.
This repository is designed to be installed by skill-aware coding agents so they can apply consistent Effect conventions, architecture guidance, and repo-backed best practices.
Installation
npx skills add Effect-TS/skills
Included Skills
effect-ts
The main Effect skill directs agents to the guidance shipped with the installed Effect package at node_modules/effect/AGENTS.md.
effect-v3-to-v4
A bounded migration skill for upgrading a codebase from Effect v3 to Effect v4. It drives the migration from the generated migration/v3-to-v4.md reference in the Effect repo:
- shallow local checkouts of the v4 (
main) and v3 branches - search-only access to the migration reference (never read whole)
- an escalation chain from reference doc to topic guides to v4/v3 source
- repo-level guidance for package consolidation and version alignment

SKILL.md
Conventions:
- each skill lives at
skills/<skill-name>/SKILL.md - skills can include supporting files when needed
Purpose
The main skill keeps guidance aligned with the installed Effect version by relying on the package's own AGENTS.md. The migration skill provides a focused workflow for v3-to-v4 upgrades.
Developing Skills
When adding a new skill:
- create
skills/<skill-name>/SKILL.md - add supporting files only when the skill needs them
- keep the skill operational and concise
