Hotfix Workflow

Hotfix Workflow

Streamlined emergency hotfix process: creates hotfix branch from main/master, applies the fix, runs quick validation, and creates PR for immediate merge.

🎯 Use Case Demo

Scenario: Production Critical Bug

Before (Manual Process):

Alert: Payment processing is failing in production!

Developer scrambles:

1. git stash current work (forget which branch)
2. git checkout main && git pull
3. git checkout -b hotfix/payment-fix
4. Find the bug, make the fix
5. git add . && git commit -m "fix payment"
6. git push -u origin hotfix/payment-fix
7. Open browser, navigate to GitHub, create PR
8. Wait for review, merge
9. Remember to go back to original work

Time: 20-30 minutes under pressure, error-prone

After (With This Skill):

Developer: "Apply hotfix for FB-99: Payment null reference error in PaymentService.cs line 45"
