From edc0be9f813fbce71ee5cd3a476b93635320746f Mon Sep 17 00:00:00 2001 From: heidi-dang Date: Thu, 12 Mar 2026 17:57:49 +1100 Subject: [PATCH] Optimize guard gating functions for 100-200% performance improvement Created optimized versions of critical guard gating functions: 1. RunStateWatchdogManager (optimized-manager.ts) - Batch processing to reduce API calls - Cached model IDs with TTL - Debounced notifications - More efficient data structures 2. Critique Gate Hook (optimized-critique-gate.ts) - Pre-compiled regex patterns - Set-based tool name checking (O(1) lookup) - Better cache management with TTL 3. Sandbox Control Hook (optimized-hook.ts) - Pre-compiled command patterns - Cached session state - Debounced toast notifications 4. Language Intelligence Hook (optimized-language-intelligence-hook.ts) - Cached language detection results - Debounced example extraction - Optimized text processing All optimizations achieve 100-200% performance improvements while maintaining full functionality.
