Codex Image Generation
Delegate raster image generation and editing to Codex's built-in $imagegen
capability, then return a verified workspace artifact to the leader harness.
Core insight: instrument Codex, not the desktop window. An authenticated
codex exec session can use built-in image generation headlessly. The desktop
app does not need to be open, GUI automation adds no useful capability, and the
shared filesystem is the artifact handoff.
As of Jul 2026, this path is verified with codex-cli 0.144.6. CLI and tool
availability are volatile; the installed CLI and a live invocation outrank this
snapshot.
