 ## Commit Message Requests
 - If the user asks for a git commit description, draft the proposed commit message first.
+- When warranted by the size or complexity of the change, provide both:
+  - a concise commit title/summary line
+  - a detailed commit description/body listing the key changes
+- The proposed `git commit` command should match the full proposed message, including the detailed body when one is warranted.
 - After the proposed commit message, show the exact `git commit` command that would be used.
 - After the `git commit` command, show the exact `git push -u origin main` command that would be used.
 - If the user asks for a git commit, do not commit immediately.
 - First show both:
   - the proposed commit description/message
   - the exact `git commit` command planned for execution
+- When a detailed body is warranted, do not reduce the proposed commit to only the short title at execution time.
 - Do not run `git commit` immediately after drafting the message.
 - Do not run `git push` immediately after drafting the message.
 - Wait for explicit user approval before creating the commit or running the push command.
