Make capture hooks async to eliminate 6s+ blocking per turn#45
Conversation
DB INSERT takes ~3s per call (server-side). UserPromptSubmit and Stop were blocking, adding ~6s latency per turn. Now async — capture runs in background while Claude responds immediately. Before: ~9s overhead per turn (UserPromptSubmit 5.5s + Stop 3.3s) After: ~0.1s overhead (only PreToolUse is blocking at 94ms) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
Root cause
DB INSERT takes ~3s server-side (
execution_time_ms: 2820). Each capture hook does one INSERT.With 2 blocking capture hooks per turn, user waited ~6-9s of pure overhead.
