# HyperFrames v0.8.21

By Steven Van · 2026-08-31

Studio agents can now see the current frame, select and inspect elements, edit content, transform layouts, and author motion through WebMCP.

[HyperFrames](<https://creatorstoolbox.com/resources/hyperframes>)'s Studio editor now exposes itself to AI agents over WebMCP. An agent can see the current frame, select and inspect elements, edit text and styles, transform layouts, and author motion, rather than only driving the CLI.

- Studio agents can drive selection and the playhead, inspect the frame, edit content and styles (guarded), and author motion.

- Preview assets now revalidate on every request instead of going stale.

- A hidden sub-composition child can be shown again.

- The player rebinds timelines and paused seeks correctly, and now reports and fails closed on runtime delivery errors instead of stalling silently.

Full details are in the [v0.8.21 changelog](<https://hyperframes.heygen.com/changelog#hyper-frames-v0-8-21>).
