Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install effect-typed-error-handling

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 separates typed errors (the E channel) from defects, creates tagged errors and applies catchTag, catchTags, catchAll or either as needed. You get explicit error handling, visible in the signature.
