Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install coverage-regression-investigation

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 generates the coverage report, compares it with the main branch, finds the least covered files and links them to recent changes. You get the files and commits responsible and the tests to add.
