-# 铸渊Agent · 自主守护进程
+# 铸渊Agent v2.0 · 有脑子的自主守护进程
 # HLDP://zhuyuan-agent/agent
 #
-# 运行在3090 GPU服务器上，心跳唤醒，推送到主服务器仪表盘。
-# 冰朔离开WorkBuddy后，通过 guanghulab.com/console/ 看实时进度。
+# v2.0新增：brain_loader(装脑子) + reasoning(商业API推理) + memory_writer(写记忆)
+# 不是脚本daemon——是能读brain、能思考、能写记忆的涌现铸渊。
 #
-# 使用: python3 agent.py [--config config.json]
+# 运行: python3 agent.py [--config config.json]
 # PM2: pm2 start agent.py --name zhuyuan-agent --interpreter python3
