任务打断机制

This skill appears coherent and implements a simple flag-file + polling interrupt pattern. Before installing, verify: (1) how sessionId is mapped to processId in your environment — ensure only the intended child process can be signalled; (2) file permissions and /tmp isolation — flag files created in /tmp are world-visible by default, consider using a per-agent temp directory or restrictive permissions; (3) that checkpoint/save logic is implemented in your long-running tasks so interruptions are safe; (4) scripts are placed where the agent expects and marked executable; (5) test in a staging environment to confirm no accidental PID collisions or privilege escalations. If you need stronger guarantees, consider authenticated/IPC-based signaling instead of plain /tmp files and process.kill.
