Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install swift-best-practices-guide

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 applies Swift 6 best practices to iOS or macOS code: the concurrency model, actors and MainActor, API design, availability patterns and AppKit pitfalls. It also helps migrate Swift 5 code and address concurrency warnings.
