 ## ⚠️ Required Pre-Submission Checklist
-<!-- ⛔ Pull requests will NOT be considered for review unless ALL required items are completed -->
-<!-- All items below are MANDATORY prerequisites for submission -->
-- [ ] Code adheres to project style guidelines and conventions
-- [ ] Branch synchronized with latest `develop` branch
-- [ ] Automated unit/integration tests added/updated to cover changes
-- [ ] All tests pass locally (`./gradlew test` for backend)
-- [ ] Manual testing completed in local development environment
-- [ ] Flyway migration versioning follows correct sequence _(if database schema modified)_
-- [ ] Documentation pull request submitted to [booklore-docs](https://github.com/booklore-app/booklore-docs) _(required for features or enhancements that introduce user-facing or visual changes)_
 
+### **Please Read - This Checklist is Mandatory**
+
+> **Important Notice:** We've experienced several production bugs recently due to incomplete pre-submission checks. To maintain code quality and prevent issues from reaching production, we're enforcing stricter adherence to this checklist.
+>
+> **All checkboxes below must be completed before requesting review.** PRs that haven't completed these requirements will be sent back for completion.
+
+#### **Mandatory Requirements** _(please check ALL boxes)_:
+
+- [ ] **Code adheres to project style guidelines and conventions**
+- [ ] **Branch synchronized with latest `develop` branch** _(please resolve any merge conflicts)_
+- [ ] **🚨 CRITICAL: Automated unit/integration tests added/updated to cover changes** _(MANDATORY for ALL backend changes - this is non-negotiable)_
+- [ ] **🚨 CRITICAL: All tests pass locally** _(run `./gradlew test` for backend - NO EXCEPTIONS)_
+- [ ] **🚨 CRITICAL: Manual testing completed in local development environment** _(verify your changes work AND no existing functionality is broken - test related features thoroughly)_
+- [ ] **Flyway migration versioning follows correct sequence** _(if database schema was modified)_
+- [ ] **Documentation PR submitted to [booklore-docs](https://github.com/booklore-app/booklore-docs)** _(required for features or enhancements that introduce user-facing or visual changes)_
+
+#### **Why This Matters:**
+
+Recent production incidents have been traced back to:
+
+- **Incomplete testing coverage (especially backend)**
+- Merge conflicts not resolved before merge
+- Missing documentation for new features
+
+**Backend changes without tests will not be accepted.** By completing this checklist thoroughly, you're helping maintain the quality and stability of Booklore for all users.
+
+**Note to Reviewers:** Please verify the checklist is complete before beginning your review. If items are unchecked, kindly ask the contributor to complete them first.
