Your agent does not crash. A tool hands back 214KB of logs, the window overflows, and the answers quietly get worse with no error. Another agent calls the same tool 14 times because the response never said it was done. A third waits 17 seconds on a slow API and gets a 424. Three fixes, with before and after numbers from the demos: keep large output out of the window and return a pointer, give the agent a clear done signal, and hand back a job id instead of blocking.

Outline:
• Three Silent Failures
• Fix 1: Memory Pointer Pattern
• Fix 2: Async HandleId for MCP
• Fix 3: DebounceHook + Clear States
• Decision Matrix + Resources
