Inline assistant stopped before completing `{REWRITE_SECTION

Error message

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

What it means

Emitted in the streaming phase after the first rewrite_section tool has started: the completion stream stops (Stop event) before the in-progress rewrite completes. Unlike the pre-rewrite stop, this fires mid-edit; the offending condition is a premature Stop(reason) truncating the model's output while the rewrite payload is still incomplete.

Solutions

1. Retry the inline assist — mid-rewrite truncation is usually transient
2. Shrink the selection or instruction so the rewrite payload fits the output limit
3. Use a model with a larger output budget for long rewrites
