Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install ios-crash-hunting-tdd

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 searches Swift code for data races, retain cycles, SwiftData context misuse and concurrency blockages. For each case it writes a failing test, then proposes the fix. You get proof of the bug and a verified correction.
