Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install effect-promise-utilities

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 writes self-contained Effect functions to add timeouts, retries with backoff, tagged errors and caching, then exposes them as Promises via Effect.runPromise. You get more robust async calls with no dependency container.
