Inline assistant response ended without completing `{REWRITE

Error message

Inline assistant response ended without completing `{REWRITE_SECTION_TOOL_NAME}` or `{FAILURE_MESSAGE_TOOL_NAME}`

What it means

The completion event stream ended (next() returned None) without the model having emitted a completed rewrite_section or failure_message tool call, so the inline assist cannot produce an edit and errors.

Solutions

1. Retry the inline assist: transient stream truncation often resolves itself
2. If it recurs, use a shorter target selection to reduce response length
3. Check the model provider status for dropped streaming connections
