+description: >
+  Make a git commit, asking if it was by the user or AI. User commits use git
+  config for both committer and author. AI commits use git config for committer
+  but set author to AI Bot <ai@local>.

+Make a git commit, distinguishing between user and AI contributions.
+
+---
+
+**Steps**
+
+1. **Ask user if this commit is by them or by AI**
+
+   Use the **question tool** to ask:
+   > "Was this commit made by you or by AI?"
+
+   Options:
+   - "By me" - User made the commit
+   - "By AI" - AI made the commit
+
+2. **Check for commit message**
+
+   If the user did NOT provide a commit message, generate one from staged changes:
+   ```bash
+   git diff --staged --stat
+   ```
+   Create a reasonable commit message based on the changes.
+
+   **Capitalization rule**: Commit message should start with a capital letter,
+   unless it refers to a tool or project that explicitly uses lowercase as its
+   name (e.g., "go", "npm", "rustc").
+
+3. **Show commit message and confirm**
+
+   Display the commit message to the user.
+
+   Use the **question tool** to ask:
+   > "Is this commit message okay, or would you like to make tweaks?"
+
+   Options:
+   - "Looks good" - Proceed with this message
+   - "Make tweaks" - User will provide a new message
+
+   **If user wants tweaks**: Ask them for the new commit message.
+
+4. **Get git user config**
+
+   ```bash
+   git config user.name
+   git config user.email
+   ```
+
+5. **Make the commit**
+
+   Use the commit message provided by the user.
+
+   **If by user:**
+   ```bash
+   git commit -m "<message>"
+   ```
+   (Uses git config user as both committer and author)
+
+   **If by AI:**
+   ```bash
+   git -c user.name="<git-config-name>" -c user.email="<git-config-email>" commit -m "<message>" --author="AI Bot <ai@local>"
+   ```
+   (Uses git config for committer, but sets author to AI Bot)
+
+6. **Show result**
+
+   ```bash
+   git log -1 --oneline
+   ```
+
+**Output**
+
+- Show the commit hash and message
+- If AI commit, mention that the author was set to "AI Bot <ai@local>"
