Verify installation
Confirm successful installation by checking the skill directory location:
.cursor/skills/axiom-memory-debugging
Restart Cursor to activate axiom-memory-debugging. Access via /axiom-memory-debugging in your agent's command palette.

Security Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.
Users shouldn't notice jetsam. Use @SceneStorage (SwiftUI) or stateRestorationActivity (UIKit) to restore navigation position, drafts, and scroll position.
Monitoring with MetricKit
classJetsamMonitor:NSObject,MXMetricManagerSubscriber{funcdidReceive(_ payloads:[MXMetricPayload]){for payload in payloads {guardlet exitData = payload.applicationExitMetrics else{continue}let bgData = exitData.backgroundExitData
if bgData.cumulativeMemoryPressureExitCount >0{// Send to analytics}}}}
App memory grows while in USE? → Memory leak (fix retention)
App killed in BACKGROUND? → Jetsam (reduce bg memory)
Common Memory Leak Patterns (With Fixes)
Pattern 1: Timer Leaks (Most Common — 50% of leaks)
Why [weak self] alone doesn't fix timer leaks: The RunLoop retains scheduled timers. [weak self] only prevents the closure from retaining self — the Timer object itself continues to exist and fire. You must explicitly invalidate() to break the RunLoop's retention.
❌ Leak — Timer never invalidated
progressTimer =Timer.scheduledTimer(withTimeInterval:1.0, repeats:true){[weakself]_inself?.updateProgress()}// Timer never stopped → RunLoop keeps it alive and firing forever
✅ Best fix: Combine (auto-cleanup)
cancellable =Timer.publish(every:1.0, tolerance:0.1, on:.main,in:.default).autoconnect().sink {[weakself]_inself?.updateProgress()}// No deinit needed — cancellable auto-cleans when released
Alternative: Call timer?.invalidate(); timer = nil in both the appropriate teardown method (viewWillDisappear, stop method, etc.) AND deinit.
For timer crash patterns (EXC_BAD_INSTRUCTION) and RunLoop mode issues, see axiom-timer-patterns.
Pattern 2: Observer/Notification Leaks (25% of leaks)
❌ Leak — No removeObserver
NotificationCenter.default.addObserver(self, selector:#selector(handle), name:AVAudioSession.routeChangeNotification, object:nil)// No matching removeObserver → accumulates listeners
✅ Best fix: Combine publisher
NotificationCenter.default.publisher(for:AVAudioSession.routeChangeNotification).sink {[weakself]_inself?.handleChange()}.store(in:&cancellables)// Auto-cleanup with viewModel
Alternative: NotificationCenter.default.removeObserver(self) in deinit.
Use the delegation pattern with AnyObject protocol (enables weak references) instead of closures that capture view controllers.
Pattern 6: PhotoKit Image Request Leaks
PHImageManager.requestImage() returns a PHImageRequestID that must be cancelled. Without cancellation, pending requests queue up and hold memory when scrolling.
›Access to product documentation and roadmap tools (Jira, Notion, etc.)
›Understanding of product management frameworks (RICE, Jobs-to-be-Done, etc.)
›Stakeholder contact information and communication channels
Time Estimate
30-60 minutes to see productivity improvements
Steps
1Install product management skill
2Start with user story generation for known feature
3Progress to competitive analysis: research 2-3 competitors
4Use for roadmap prioritization: apply RICE/ICE scoring
5Draft stakeholder communications and refine based on feedback
6Build template library for recurring PM tasks
7Share effective prompts with product team
Common Pitfalls
⚠Not validating competitive research—verify facts before sharing
⚠Accepting user stories without involving engineering team
⚠Over-relying on frameworks without qualitative judgment
⚠Not customizing outputs to company culture and communication style
⚠Skipping stakeholder validation of generated requirements
Best Practices
✓ Do
+Validate research and competitive analysis with real data
+Collaborate with engineering when generating technical requirements
+Customize frameworks and templates to your company context
+Use skill for first drafts, refine with stakeholder input
+Document successful prompt patterns for PM tasks
+Combine AI efficiency with human judgment and intuition
✗ Don't
−Don't publish competitive analysis without fact-checking
−Don't finalize user stories without engineering review
−Don't make prioritization decisions solely on AI scoring
−Don't skip customer validation of generated requirements
−Don't ignore company-specific context and culture
💡 Pro Tips
★Provide context: company goals, constraints, customer feedback
★Ask for alternatives: 'Show 3 ways to prioritize this roadmap'
★Request stakeholder-specific formatting: 'Executive summary vs. engineering spec'
★Use skill for 70% generation + 30% customization to company needs
When to Use This
✓ Use when
Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.
✗ Avoid when
Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.
