Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install event-sourcing-cqrs-design-2

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 models events, evolves their schemas and makes projections idempotent so they can be replayed. It works with NATS JetStream or Kafka. You get an event-driven design and versioning rules.
