Command to export a memory snapshot

This will speed up user's reporting memory issues. Right now users have to connect to chrome devtools and take a snapshot which is higher friction then just typing a command in Gemini CLI.

This could be integrated directly in /bug automatically saving a memory snapshot to disk if memory usage is over 2GB and surfacing the URL to the snapshot to let the user know they can share the snapshot with the bug if they want.

Concerns: taking a snapshot via the V8 API can be slow. We would need to make sure the bug url is shown before we potentially lock their machine for 20 seconds taking the snapshot. See the existing usage of the Node V8 API to open the debugger. We'd want to open the debugger and then use the V8 API commands to take a snapshot and save to disk. We should ensure we close the debugger after the task is complete and use an available port rather than requiring 9229.

extent analysis

TL;DR

Implement a command in Gemini CLI to export a memory snapshot using the V8 API, ensuring the debugger is closed after the task is complete.

Guidance

  • Investigate the existing usage of the Node V8 API to open the debugger and adapt it to take a snapshot and save to disk.
  • Ensure the bug URL is displayed before taking the snapshot to avoid locking the user's machine for an extended period.
  • Use an available port instead of requiring port 9229 to open the debugger.
  • Consider the potential performance impact of taking a snapshot via the V8 API and optimize the process to minimize delays.

Example

No code snippet is provided as the issue does not contain sufficient technical details to create a specific example.

Notes

The implementation should take into account the potential slowness of taking a snapshot via the V8 API and ensure a smooth user experience.

Recommendation

Apply workaround: Implement the command to export a memory snapshot using the V8 API, while ensuring the debugger is closed after the task is complete, to provide a more convenient way for users to report memory issues.
