Release Notes: Chrome Extension 0.1.77

Version 0.1.77 fixes the extension-local hosted-agent tool catalog so overlay tools are actually available to gpt-realtime-2 sessions.

What Changed

  • Added overlay.open, overlay.register_launcher, and overlay.close to the packaged extension primitive dictionary.
  • The hosted Realtime tool catalog now includes normalized overlay tools such as overlay_open even when the session starts from extension-local defaults instead of a reachable bridge tool list.
  • Tests now verify that the packaged extension manifest exposes overlay tools to the model-facing Realtime catalog.

Why It Matters

Version 0.1.76 told the model to use overlays, but the current session logs showed overlay_open was missing from session.update.tools. The model was therefore correct that it had no overlay tool in that session.

This release fixes the catalog source, not just the prompt.

Suggested Smoke Test

  1. Install extension 0.1.77.
  2. Start a hosted agent session.
  3. Pull runtime.session.log.
  4. Confirm realtime.session.update.tools includes overlay_open.
  5. Ask the agent to put a summary in an overlay.
