The image-generate tool showed a placeholder, then the model echoed a
(often different) image inline in its prose — a second, jarring copy in
the wrong place, dimmed as tool scaffolding, with a misplaced download
button.
Now the generated image lives only in the tool slot:
- Strip every embedded image/media link from the assistant prose of a
message that produced an image (the model frequently restates the
remote URL while the result holds the local path), preserving the
agent's words. Applied on hydration, live deltas, and completion.
- One stable frame sized from the aspect_ratio arg up front, so the
diffusion placeholder and the decoded image share the same box and
crossfade with no layout shift; the box derives its height from the
true ratio on load (no letterboxing).
- Exempt generated images from the tool-block dim-until-hover rule.
- Extract a shared useImageDownload hook + ImageLightbox so the tool
image and markdown images share one implementation.
