Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install test-coverage-analysis

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 configures Istanbul, V8 or coverage.py, finds gaps in critical code and sets a diff coverage gate on changed lines. It adds mutation testing to check whether assertions catch real regressions.
