Hey, thanks for the report.
Important: Ask is read-only and doesn’t change files. For modifications, switch to Agent or Plan:
To understand why Ask loops instead of replying:
Share 2–3 recent Request IDs from the stuck conversation (chat menu top right > Copy Request ID)
Console logs: Help > Toggle Developer Tools > Console, reproduce the hang and copy errors
The model where it reproduces (e.g., Composer 1, Sonnet 4.5, GPT, etc.)
Check if it reproduces in Agent mode with the same prompt
Run without extensions: from terminal cursor --disable-extensions and check
Send the info above and we’ll attach it to the investigation.
I understand that ask is read-only, but sometimes I mistakenly use it when I want to use agent mode, and in these cases the model should not hang forever.
