 - Media understanding (if configured via `tools.media.*` or shared `tools.media.models`) runs before templating and can insert `[Image]`, `[Audio]`, and `[Video]` blocks into `Body`.
   - Audio sets `{{Transcript}}` and uses the transcript for command parsing so slash commands still work.
   - Video and image descriptions preserve any caption text for command parsing.
+  - If the active primary image model already supports vision natively, OpenClaw skips the `[Image]` summary block and passes the original image to the model instead.
 - By default only the first matching image/audio/video attachment is processed; set `tools.media.<cap>.attachments` to process multiple attachments.
