┌──────────────────────────────────────────────────────────────┐
│ MANDATORY RULES FOR EVERY SUGGESTION TASK │
│ │
│ 1. UNDERSTAND THE FEATURE BEFORE SUGGESTING CHANGES │
│ → Read the full requirement and existing implementation │
│ → Understand the user persona and their actual workflow │
│ → Don't suggest improvements to problems that don't │
│ exist │
│ → Context first, opinions second │
│ │
│ 2. EVERY SUGGESTION MUST HAVE A USER BENEFIT │
│ → "This would be cool" is not a reason │
│ → Each suggestion must answer: "This helps the user │
│ because..." │
│ → Prioritize suggestions by user impact, not technical │
│ elegance │
│ → Focus on what users need, not what's fun to build │
│ │
│ 3. THINK ABOUT WHAT'S MISSING, NOT JUST WHAT'S THERE │
│ → Empty states — what does the user see with no data? │
│ → Error states — what happens when things go wrong? │
│ → Edge cases — what about 0 items? 10,000 items? │
│ → Permissions — what should each role see/not see? │
│ │
│ 4. FEASIBILITY MATTERS │
│ → Estimate effort for each suggestion (small/medium/ │
│ large) │
│ → Flag suggestions that need new infrastructure │
│ → Separate quick wins from larger initiatives │
│ → A brilliant idea that takes 6 months is not a │
│ suggestion — it's a roadmap item │
│ │
│ 5. DON'T OVER-SUGGEST │
│ → Quality over quantity — 5 strong suggestions beat │
│ 20 weak ones │
│ → Group related suggestions together │
│ → Rank by impact: must-have → should-have → nice-to-have │
│ → Know when the feature is "good enough" to ship │
│ │
│ 6. NO AI TOOL REFERENCES — ANYWHERE │
│ → No AI mentions in suggestions or documentation │
│ → All output reads as if written by a product-minded │
│ engineer │

Before suggesting anything, fully understand what was asked.
Read the task and extract:
┌──────────────────────────────────────────────────────────────┐
│ REQUIREMENT BREAKDOWN │
│ │
│ 1. WHO is the user? │
│ → Which role/persona will use this? │
│ → Admin? End user? Both? Anonymous? │
│ │
│ 2. WHAT do they want to do? │
│ → The core action or feature │
│ → Write it as: "User can [action] on [object]" │
│ │
│ 3. WHY do they want it? │
│ → Business goal behind the request │
│ → What problem does this solve? │
│ │
│ 4. WHERE does it live? │
│ → Which page, section, or flow? │
│ → New page or addition to existing? │
│ │
│ 5. WHEN does it happen? │
│ → Trigger event (click, schedule, webhook?) │
│ → Is there a sequence or dependency? │
└──────────────────────────────────────────────────────────────┘
Before suggesting anything, understand what already exists:
| Check | Why |
|---|---|
| Does a similar feature already exist? | Avoid suggesting something that's already built |
| What patterns does the project use? | Suggestions should fit the existing architecture |
| What data models are relevant? | Understand what's already in the database |
| What APIs are related? | Know what endpoints and services exist |
| What UI components are available? | Suggest using existing components, not new ones |
Run the requirement through each of these lenses. For every gap found, decide: is this a "must discuss" or a "we can just do this"?
┌──────────────────────────────────────────────────────────────┐
│ GAP ANALYSIS — 10 LENSES │
│ │
│ For each lens, ask: "Did the requirement cover this?" │
│ If NO → it's a gap. Document it. │

Every finding goes into one of two categories:
┌──────────────────────────────────────────────────────────────┐
│ │
│ BUCKET A: "MUST DISCUSS WITH CLIENT" │
│ ───────────────────────────────────── │
│ Things that need a decision before we can build. │
│ We CANNOT assume the answer. │
│ │
│ Examples: │
│ → "Should admins be able to delete other admins?" │
│ → "Should the export include archived records?" │
│ → "What happens to active subscriptions when a user │
│ is deactivated?" │
│ → "Do you want email notifications for this action?" │
│ → "Should this be accessible to all roles or just admins?" │
│ │
│ ──────────────────────────────────────────────────────── │
│ │
│ BUCKET B: "WE CAN JUST DO THIS" │
│ ───────────────────────────────── │
│ Improvements we should add without asking because they │
│ are industry standard, best practice, or obviously needed. │
│ NOT doing them would be a gap. │
│ │
│ Examples: │
│ → Add loading states on all async actions │
│ → Add confirmation dialog before delete │
│ → Add input validation with clear error messages │
│ → Add empty state when there's no data │
│ → Add pagination for lists that could grow │
│ → Add proper error handling with user-friendly messages │
│ → Add toast notifications on success/failure │
│ → Add search/filter on listing pages │
│ → Sanitize all user inputs │
│ → Add proper 404/403 pages for edge cases │
│ │
└──────────────────────────────────────────────────────────────┘
Is the answer obvious from best practices or industry standard?
│
├── YES
│ │
│ ├── Is it a small effort? (< 1 hour extra)
│ │ ├── YES → BUCKET B: Just do it
│ │ └── NO → BUCKET A: Mention it, get approval for the effort
│ │
│ └── Could doing it wrong cause data loss or security issues?
│ ├── YES → BUCKET A: Discuss first
│ └── NO → BUCKET B: Just do it
│
└── NO — The answer depends on business rules or client preference
│
└── BUCKET A: Must discuss

Here's what a real suggestion report looks like:
## Suggestion Report: User Deactivation Feature
### Requirement Summary
Client asked: "Add ability for admins to deactivate users."
### Questions for Client (Must Discuss)
1. **What happens to the deactivated user's active sessions?**
→ Should they be logged out immediately, or can they finish their current session?
Options: (a) Immediate logout (b) Session expires naturally
2. **Can a deactivated user be reactivated?**
→ If yes, should their data (courses, progress) be preserved?
→ If no, should we delete their data after X days?
3. **Should deactivated users count toward the billing seat limit?**
→ This affects how we query active users for Stripe
4. **Who should be notified?**
→ Should the deactivated user receive an email?
→ Should other admins be notified?
### Improvements We Will Add (No Discussion Needed)
1. **Confirmation dialog before deactivation**
→ Destructive action — must have "Are you sure?" with user's name shown
2. **Prevent self-deactivation**
→ Admin should not be able to deactivate their own account
3. **Prevent deactivating the last admin**
→ At least one active admin must remain
4. **Audit log entry**
→ Record who deactivated whom and when
5. **Visual indicator on user list**
→ Show deactivated users with a grey badge, not mixed with active
6. **Filter on user list**
→ Add "Status: Active / Deactivated / All" filter
### Risks & Watch-Outs
- **Data integrity**: Deactivated users may own courses, be assigned
to paths, or have pending submissions. Each relationship needs
a defined behavior.
- **API tokens**: If the user has API keys, those should be revoked
on deactivation.
- **Search**: Deactivated users should be excluded from search
results by default (user assignment dialogs, etc.).
### Suggested Approach
Use a `status` field on the users table (active/deactivated) rather
than deleting records. Add middleware to reject API calls from
deactivated users. Filter them out of all user-facing queries by
default, with an admin toggle to include them.

│ BONUS VALUE — THINGS TO ALWAYS INCLUDE │
│ │
│ These are things clients expect but rarely write in the │
│ requirement. Including them shows professionalism. │
│ │
│ UX POLISH │
│ → Empty states with helpful text ("No users yet. Invite │
│ your first team member to get started.") │
│ → Loading skeletons instead of blank screens │
│ → Disabled buttons with tooltips explaining why │
│ → Breadcrumbs for navigation context │
│ → Keyboard shortcuts for power users │
│ │
│ DATA PROTECTION │
│ → Soft delete (never hard delete user data) │
│ → Audit trail for admin actions │
│ → Prevent deleting the last admin/owner │
│ → Prevent self-destructive actions │
│ │
│ COMMUNICATION │
│ → Success toasts after every action │
│ → Error messages that tell the user what to do next │
│ → Email notifications for important events │
│ → In-app notifications as a secondary channel │
│ │
│ PERFORMANCE │
│ → Pagination on every list (never load all records) │
│ → Debounced search inputs │
│ → Optimistic UI updates for fast feedback │
│ → Cached queries for data that doesn't change often │
│ │
│ SECURITY │
│ → Rate limiting on sensitive endpoints │
│ → Input sanitization against XSS │
