Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install a2ui-declarative-agent-interfaces

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 describes the interface in declarative JSON that your client displays with its own components. It uses the six message types, the flat component model and JSON Pointer data binding. It adds actions and validation rules. You keep control over which components appear.
