Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install property-based-testing-fast-check

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 writes tests that check properties such as encode-decode round trips or commutativity, using fast-check or Hypothesis generators, and tunes run configuration. You get tests that explore many cases instead of fixed examples.
