Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install detect-duplicated-code-in-review

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 extracts the new code's logic, searches for existing locations and their dependencies, then compares against project best practices. You get precise feedback pointing to existing code to reuse.
