Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install architecture-fitness-functions-2

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 translates a rule described in plain language into a TypeScript fitness function, places it globally or next to the element it governs, then runs eventcatalog fitness check. It verifies the result and wires the rule into CI. You get a rule that flags architecture drift.
