What version of the IDE extension are you using?

26.5409.20454

What subscription do you have?

Pro

Which IDE are you using?

VS Code

What platform is your computer?

Linux 6.1.129-138.220.amzn2023.x86_64 x86_64 x86_64

What issue are you seeing?

The subagents say they're waiting for instruction, but the white "Open" link/button next to them doesn't seem to do anything. The coordinator (GPT-5.4 Extra High) doesn't seem to be fielding their questions very well either.

What steps can reproduce the bug?

  1. ask it to launch subagents
  2. try to step into each subagents and attend to its user-facing issues

What is the expected behavior?

No response

Additional information

wish i still had the screenshot of the UI, but accidentally overwrite clipboard with uname command for platform version answer above.

TL;DR

The issue may be related to the interaction between the subagents and the coordinator, and checking the configuration or logs related to these components could provide more insight.

Guidance

  • Verify that the subagents are properly configured and connected to the coordinator (GPT-5.4 Extra High) to ensure they are receiving instructions correctly.
  • Check if there are any known issues or limitations with the specific version of the IDE extension (26.5409.20454) that could be causing the problem.
  • Attempt to reproduce the issue with a different coordinator or subagent configuration to isolate the problem.
  • If possible, try to retrieve or recreate the screenshot of the UI to provide more visual context for the issue.

Notes

The lack of a screenshot and specific error messages makes it difficult to provide a more detailed solution. Additionally, the issue may be specific to the Pro subscription or the Linux platform.

Recommendation

Apply workaround: Try adjusting the subagent and coordinator configuration to see if it resolves the issue, as the problem may be related to a specific setting or compatibility issue.
