Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install swift-concurrency-diagnostics-migration

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 identifies the isolation boundary (actors, @MainActor, Sendable), explains the compiler diagnostic and proposes the safest fix. It also converts callback code to async/await and follows a validation loop for the Swift 6 migration.
