| description | Use Hana Media Generation tools for image and video generation. Read before calling media_generate-image, media_generate-video, or media_describe-options. |
Media Generation
Generation is asynchronous. After submission, the tool returns immediately with a pending media block. Tell the user the image or video is being generated and will appear automatically when finished. Do not wait for the background task and do not call stage_files for generated media.
Tools
media_generate-image
prompt is required.count controls concurrent image count.image accepts a current-session reference image. Prefer { "kind": "session_file", "fileId": "..." }.referenceImages accepts multiple current-session reference images. Prefer session_file references.ratio, resolution, and quality are normal generation controls.provider, model, mode, and options are advanced overrides. Omit them for ordinary generation unless the user explicitly asked for a provider/model/mode or media_describe-options shows they are needed.- Do not put mode values such as
text2image or image2image in model.
media_generate-video
prompt is required.image is for image-to-video. Prefer { "kind": "session_file", "fileId": "..." }.duration, ratio, and resolution are normal generation controls.provider, model, mode, and options are advanced overrides. Omit them for ordinary generation unless the user explicitly asked for them.
media_describe-options
Use this side-effect-free tool only when the user asks for a specific provider/model/mode, asks for advanced parameters, or a default generation path reports a clear unsupported-capability error.
Routing
| Intent | Tool |
|---|
| Generate an image from text | media_generate-image |
| Edit or restyle a reference image | media_generate-image with image |
| Blend several reference images | media_generate-image with referenceImages |
| Generate a video from text | media_generate-video |
| Animate an image | media_generate-video with image |
| Inspect provider/model/mode options | media_describe-options |
Rules
- Use only the
media_* tools for image and video generation.
- Do not silently switch providers after a failure. Report the error unless the user asks you to try another provider.
- Provider capability comes from Hana Media Provider Registry, not from chat model names.
- If the user wants text inside the image, put the exact text in double quotes inside the prompt.
