+# Git Guide
+
+This file records repo-specific git workflow preferences for `/home/aw/code/cds`.
+
+## Commit Message Requests
+- If the user asks for a git commit description, draft the proposed commit message first.
+- Do not run `git commit` immediately after drafting the message.
+- Wait for explicit user approval before creating the commit.
+
+## Commit Scope
+- When committing, include only the files relevant to the approved change.
+- Leave unrelated worktree changes uncommitted unless the user explicitly asks to include them.
