Deno Debugger Skill

Debug Deno/TypeScript applications using the V8 Inspector Protocol with pre-written TypeScript helper scripts.

When to Use This Skill

• User reports memory leaks in their Deno application
• API endpoints are slow and need profiling
• Async operations complete in the wrong order (race conditions)
• Application crashes or throws unexpected exceptions
• User wants to understand memory usage or CPU hotspots

⚠️ CRITICAL: Use Pre-written Scripts

DO NOT write your own CDP client, heap analyzer, or profiler code.

All infrastructure is already implemented in ./scripts/:

• cdp_client.ts - Complete CDP WebSocket client
• heap_analyzer.ts - Heap snapshot parsing and analysis
