Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# 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. 1. 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. 2. Search `.shob/references/effect-smol` for exact APIs, examples, tests, and naming patterns before answering or implementing Effect-specific code. 3. Also inspect existing repo code for local house style before introducing new patterns. 4. Prefer answers and implementations backed by specific source files or nearby repo examples. ## Guidelines - Prefer current Effect v4 APIs and project-local patterns over old blog posts, examples, or package-memory guesses. - Use `Effect.gen(function* () { ... })` for multi-step workflows. - Use `Effect.fn("Name")` or `Effect.fnUntraced(...)` for named effects when adding reusable service methods or important workflows. - Prefer Effect `Schema` for API and domain data shapes. Use branded schemas for IDs and `Schema.TaggedErrorClass` for typed domain errors when modeling new error surfac

What does the effect skill do?
Work with Effect v4 / effect-smol TypeScript code in this repo
How do I install it?
Run `npx skills add shobcoder/shob --skill effect --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From shobcoder/shob, a repository with 583 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
