Documentation

README

Excerpt

Effect

This codebase uses Effect for typed, composable TypeScript services, schemas, and workflows.

Source Of Truth

Use the current Effect v4 / effect-smol source, not memory or older Effect v2/v3 examples.

If .shob/references/effect-smol is missing, clone https://github.com/Effect-TS/effect-smol there. Do this in the project, not in the skill folder.
Search .shob/references/effect-smol for exact APIs, examples, tests, and naming patterns before answering or implementing Effect-specific code.
Also inspect existing repo code for local house style before introducing new patterns.
Prefer answers and implementations backed by specific source files or nearby repo examples.

Guidelines

This is the opening of the README. Read the full README on GitHub.
