Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install code-comment-gate-rules

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

Before any comment, the agent asks one gate question: does this tell a future reader something the code doesn't? It removes comments that restate the code, narrate history or keep commented-out code, and keeps only explanations of why. You get code that reads cleanly.
