Effect-TS guide for TypeScript, v4 default with v3 support. Use when writing, debugging, or reviewing Effect code across errors, concurrency, services, streams, and schema, or when code imports from 'effect' or any '@effect/*' package.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Effect-TS Effect is a TypeScript library for building production-grade software with typed errors, structured concurrency, dependency injection, and built-in observability. ## Version Detection Before writing Effect code, detect which version the user is on: ```bash # Check installed version cat package.json | grep '"effect"' ``` - **v4.x** (recommended, the direction Effect is heading): `Context.Service`, `Effect.catch`, `Effect.forkChild`, `Schema.TaggedErrorClass` - **v3.x** (stable, still common in production): `Context.Tag`, `Effect.catchAll`, `Effect.fork`, `Data.TaggedError` > Note: v4 beta briefly used a `ServiceMap` module, renamed back to `Context` on 2026-04-07 (PR #1961). If you see `ServiceMap.*` in any doc or older beta code, it is the current `Context.*`. Both v3 and v4 import `Context` from `"effect"`; the exports inside differ (`Context.Service` in v4 vs `Context.Tag` in v3). …

How to install
mdr add tenequm/skills/effect-ts@sha256:ac6620e1f57fbaa1The line at the top of this page pins the label v0.6.5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
