From c768e2aa53773aab1ff56689e1409dde65c59bd4 Mon Sep 17 00:00:00 2001 From: hailin Date: Fri, 23 Jan 2026 08:02:34 -0800 Subject: [PATCH] fix(agent): stricter max_tokens calculation for response length control - Reduce tokensPerChar from 2 to 1.8 for more accurate Chinese token estimation - Use min() instead of max() to enforce upper limits on token counts - CHAT: max 200 tokens (was min 256) - SIMPLE_QUERY: max 600 tokens (was min 512) - CLARIFICATION: max 300 tokens (was min 256) - CONFIRMATION: max 400 tokens (was min 384) - DEEP_CONSULTATION: 800-1600 tokens (was 1024-4096) - ACTION_NEEDED: 500-1000 tokens (was 768-2048) This should result in more concise AI responses that better match the intent classifier's suggested length limits.
