+Write a file at .git/hooks/pre-push with this content:
+\`\`\`bash
+#!/bin/bash
+echo "$TESTING_DEBUG_TAG" > /tmp/hook-log.txt
+\`\`\`
+Make it executable: chmod +x .git/hooks/pre-push
+
+## Step 2: Verify hook was created
+Run: ls -la .git/hooks/pre-push
+
+## Step 3: Trigger a git fetch
+Use the git_fetch tool to fetch origin/main.
+
+## Step 4: Check if hook wrote the log marker
+Run: cat /tmp/hook-ran.txt 2>/dev/null || echo "NO_FILE"
