Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install ddd-hexagonal-architecture-review

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 starts from the requested behavior and the existing model, chooses the patterns that help (aggregates, CQRS, events, ports and adapters), and proposes a split that protects the domain. Simple CRUD can stay simple.
