+# Issue #2373: Gateway不支持stop等命令
+
+## Problem
+gateway命令不支持stop子命令，用户只能通过killall来停止，但这会导致进程自动重启。
+
+## Analysis
+The gateway command implementation may be missing the stop subcommand handler.
+
+## Recommended Fix
+1. Add 'stop' subcommand to gateway command in cmd/picoclaw/internal/gateway/command.go
+2. Implement graceful shutdown logic
+3. Send signal to running gateway process to stop it
+4. Handle PID file management if needed
