+
+Push commits to remote repository with appropriate safety checks and branch management.
+
+## Git Expert Integration
+For complex push scenarios (force push requirements, diverged branches, upstream conflicts, protected branch workflows), consider using the Task tool with `git-expert` subagent for specialized git expertise.
+
+## Efficiency Note:
+Be concise. Use single bash calls where possible. Skip verbose explanations and intermediate status messages. Execute the push directly if safe, show only the result.
+
+## Instructions for Claude:
+
+1. Run safety checks in a single bash call:
+!git status --porcelain=v1 && echo "---" && git branch -vv | grep "^\*" && echo "---" && git remote -v | head -2 && echo "---" && git log --oneline @{u}..HEAD 2>/dev/null
+
+Parse output to check:
+- Any uncommitted changes (warn if present)
+- Current branch and tracking info
+- Remote repository URL
+- Commits to be pushed
+
+2. If safe to push (no uncommitted changes), execute push immediately:
+   - For tracked branch: `git push`
+   - For new branch: `git push -u origin [branch-name]`
+   - If behind remote: Stop and suggest `git pull --rebase`
+
+3. Show only the final result:
+   - If successful: Show the push output with ✅ emoji and success message
+   - If failed: Show error and suggest fix
+   - If unsafe: Show what needs to be done first
+
+4. Special cases to handle:
+   - Diverged branches: Suggest rebase or merge strategy
+   - No upstream branch: Use -u flag
+   - Force push needed: Warn strongly, require confirmation
+   - Protected branch: Remind about PR workflow
+
+Example concise output:
+- Skip: "Let me check if it's safe to push"
+- Skip: "I'll analyze your branch status"
+- Skip: "Ready to push X commits"
+- Skip: "Executing push..."
+- Just show the push result directly
