Systematic debugging with Linear integration and structured troubleshooting workflow.

wss.on('connection', (ws) => { ws.on('message', handleMessage); ws.on('close', () => { console.log('Connection closed'); // ❌ Not removing listeners! }); });

wss.on('connection', (ws) => { const messageHandler = handleMessage.bind(null, ws); ws.on('message', messageHandler); ws.on('close', () => { ws.removeListener('message', messageHandler); ws.removeAllListeners(); console.log('Connection closed and cleaned up'); }); });

Systematic debugging with defense-in-depth approach (symptoms → immediate cause → root cause → systemic issues → prevention). Auto-activates when user mentions "error", "failing", "broken", "debug", "bug", "issue" or when /ccpm:verify runs. Uses Observe → Hypothesize → Test → Confirm → Fix → Verify → Document workflow. Updates Linear with findings and automatically logs blockers that require external fixes. Traces root causes instead of patching symptoms. Integrates with ccpm-code-review to verify fixes pass all gates before marking complete. Suggests binary search for intermittent issues and five-whys analysis for complex problems.
