What it does
Design, write, review, and test production Effect v4 programs: deep services and layers, schemas, tagged errors, observability, Config, persistence, resources, concurrency, schedules, workers, streams, caches, HTTP clients, Effect platform services (Node filesystem/path/crypto/process/socket), and Effect Atom integrations. Use for any Effect application or adapter work.
Effect Program Design
Build production Effect v4 programs with small domain-shaped interfaces, typed success and error channels, declared dependencies, observable operation boundaries, and tests that substitute layers at real seams. This skill combines broad Effect mechanics with HumanLayer's deep-module, capture-before-narrow, and real-seam design standards.
Source rule
Check these before guessing:
- the nearest
CLAUDE.md/AGENTS.mdand project-local conventions; - the installed
effect,@effect/*, and related package versions and declarations; - the Effect v4 docs at https://effect-ts-effect-smol.mintlify.app/;
- the pinned/upstream source (
~/projects/effect-smol) when docs do not settle an API.
unstable-tagged modules (effect/http, effect/rpc, effect/process, ...) can change between beta/minor versions. Typecheck examples against the installed version. Local
project conventions take precedence unless the task explicitly changes them.
