Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install bun-test-mocks

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 or fixes your test doubles with mock(), spyOn() and mock.module() in the Bun runner. You get tests that check calls without depending on real services.
