Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install js-ts-codebase-health-analysis

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 runs Fallow's zero-configuration static analysis to spot dead code, duplicates, dependency cycles, complexity hotspots and boundary violations. It can also merge production runtime coverage to confirm what is really used.
