Inline assistant stopped before completing `{REWRITE_SECTION

Error message

Inline assistant stopped before completing `{REWRITE_SECTION_TOOL_NAME}` or `{FAILURE_MESSAGE_TOOL_NAME}` ({reason:?})

What it means

Emitted when the inline assistant's completion stream ends with a Stop event before the model finished either the rewrite_section or failure_message tool call. The response was cut short by a stop reason other than normal completion; the offending condition is the premature Stop(reason) on the language-model stream, leaving the edit protocol incomplete.

Solutions

1. Retry the inline assist — premature stops are often transient
2. Reduce the size of the selection being rewritten
3. Switch to a model with a larger output limit if the stop reason is length-related
