Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install effect-typescript-production-guide

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent applies Effect v4 practices: services and layers, schemas, configuration, schedules, caches, streams, HTTP clients and tests. It follows project conventions and points out differences from version 3. You get code aligned with the current API.
