+# /commit-push - Commit and Push
+
+## Purpose
+
+Create a commit and push to the remote repository in one operation.
+
+## Behavior
+
+### Step 1: Run /commit
+
+Execute the standard commit workflow (see commit.md).
+
+### Step 2: Push to Remote
+
+After successful commit:
+
+1. Check if branch has upstream tracking
+2. If no upstream, set it: `git push -u origin <branch>`
+3. If upstream exists: `git push`
+
+### Step 3: Handle Conflicts
+
+If push fails due to diverged history:
+
+```
+Remote has changes not in your local branch.
+
+Options:
+1. Pull and rebase, then push (Recommended)
+2. Pull and merge, then push
+3. Force push (⚠️ destructive)
+4. Cancel and review manually
+```
+
+## Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `GIT_AUTO_PUSH` | `true` | Auto-push after commit |
+| `GIT_PUSH_STRATEGY` | `rebase` | How to handle diverged branches |
+
+## Safety Checks
+
+- **Protected branches**: Warn before pushing to main/master/production
+- **Force push**: Require explicit confirmation
+- **No tracking**: Ask before creating new remote branch
+
+## Output
+
+On success:
+```
