# Allow Summary Title Rename

## Why
Meetings often start with generated default titles such as `Meeting 2026-06-03 07:26`. When the summary agent can infer a clear purpose from the transcript, user notes, or assistant context, it should be able to give the meeting a useful title while writing the summary.

## What
- Refine `write_summary` title handling so a non-empty title renames the current meeting and summary artifacts.
- Preserve the existing title when the title parameter is omitted or blank.
- Instruct the summary agent to provide a concise title when the meeting still has a generated default title and the meeting purpose is clear.

## Impact
- Updates summary tool behavior and instructions.
- Adds focused tests for title preservation and rename behavior.
