Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install detect-copy-paste-code

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 jscpd with the agent-friendly report, applies ignore and format filters, then reads clones in passes of increasing looseness. It can add a hotspot summary. You get the list of duplicates to review before any change.
