## What image-gen does, in the publisher's words

Cover images and in-article illustrations for technical articles.

Hosts: Claude Code, Codex, Grok Build, Cursor, SKILZ / Agent Plugins 1.0.

Not the diagram renderer. Mermaid and PlantUML go to imagen-diagrams.

- imagen CLI if on PATH. Brace policy: imagen-cli-vars (double { }).
- Then grok-img CLI. Brace policy: grok-imagine (no rewrite).
- Else codex CLI. Brace policy: grok-imagine (no rewrite).
- Else fail closed. Writes _imagen.prompt.txt and exits 2.
