Inline assistant response ended before completing `{REWRITE_

Error message

Inline assistant response ended before completing `{REWRITE_SECTION_TOOL_NAME}`

What it means

Emitted when the inline assistant's completion stream simply ends (no further events) after a rewrite_section call started but before its content fully arrived. This is the stream-exhausted counterpart to the Stop-event case: the provider closed the stream mid-rewrite; the offending condition is the truncated completion stream, not user input.

Solutions

1. Retry the inline assist — dropped streams are typically transient
2. Check the model provider's status for connection issues
3. Shorten the requested rewrite to reduce streaming time
