From 915d45ec488254083f5a3da14ff87dd1e87b7cff Mon Sep 17 00:00:00 2001 From: "nap.liu" Date: Wed, 8 Apr 2026 23:20:48 +0800 Subject: [PATCH] fix: use agent context_window_size across all channels instead of hardcoded limits Remove redundant history[-ctx_size:] slicing in _call_agent_llm since all callers already truncate history via SQL .limit(ctx_size). The remaining channel handlers (websocket, dingtalk, discord, slack, wecom, teams, discord_gateway, wecom_stream) already use agent.context_window_size with DEFAULT_CONTEXT_WINDOW_SIZE=100 fallback.
