name: skill-blocker
description: 危险技能拦截器 | Dangerous operation blocker and security gatekeeper. Blocks risky commands, unsafe file operations, and suspicious network requests before they execute. Use when you need to prevent harmful actions like destructive file deletions, credential exfiltration, or unauthorized system changes. Automatically detects and blocks patterns: rm -rf /, curl | sh, eval(), SSH to unknown hosts, modifications to sensitive config files, data exfiltration attempts. 检测并阻止危Why was this flagged?
A script or Makefile pipes content from a remote URL directly into a shell (curl | sh or wget | bash). This is inherently dangerous because the remote content can change at any time, and the command runs with the current user's permissions. Rated HIGH because it requires manual execution (unlike install hooks) but still executes arbitrary remote code.
