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.
