Current preview support is static rather than live. A quick bundle typically
contains:
- a low-res preview clip
- sampled frames
- a
heroframe for quick inspection summary.jsonwith trim/zoom/speed facts
Bundle capture also writes or updates a stable recipe-level trajectory.json
beside the preview root so agents can reconstruct preview history over time.
Viewer commands:
cli-hub previews inspect /path/to/bundle
cli-hub previews html /path/to/bundle -o page.html
cli-hub previews open /path/to/bundle

For AI Agents
- Always use
--jsonfor parseable output - Check return codes — 0 = success, non-zero = error
- Parse stderr for error messages in non-JSON mode
- Use absolute file paths
- After
export render, verify the output exists and probe it - Times are in milliseconds for all region commands
- Coordinates (focus, crop, position) are normalized 0-1
- Use
preview capture --jsonto validate zoom, trim, annotation, and timing visually - Read returned bundle artifact paths from the JSON payload; images and clips live on disk
- Use
cli-hub previews ...only to inspect/open existing bundles
