Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install mcp-tool-improvement-loop

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 scores the agent experience with an eval harness you supply, picks the highest-impact tool problem from production data and makes one bounded fix. It keeps the change only if the scores improve. You get a campaign journal and an eval-backed pull request.
