Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install modernise-xctest-to-swift-testing

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 converts test classes into suites, assertions into expectations and asynchronous waits into confirmations. UI tests and performance measurements stay in XCTest, since Swift Testing cannot replace them. You get Swift Testing tests that follow the recommended patterns.
