Error Guard — Control‑Plane Safety

Error Guard — Control‑Plane Safety extends your AI assistant with the ability to system safety and control-plane skill that prevents agent deadlocks and freezes. Provides non-LLM control commands to inspect task state, flush message queues, cancel long-running work, and recover safely without restarting the container. Use when implementing or operating long-running tasks, sub-agents, benchmarks, background monitors (e.g., Moltbook, PNR checks), or when the system becomes unresponsive and needs immediate recovery controls. Rather than leaving your conversation to handle this manually, you can ask your Claude agent directly — and it will take care of the task end-to-end, using Error Guard — Control‑Plane Safety as its underlying capability.

Error Guard — Control‑Plane Safety works across Claude, Cursor, OpenClaw through the Model Context Protocol (MCP) — an open standard that lets AI clients share tools and skills without lock-in. Because MCP is platform-agnostic by design, you install Error Guard — Control‑Plane Safety once and it becomes available across all your AI clients. Whether you're working in Claude for focused sessions or Cursor for integrated workflows, the skill behaves consistently.

Error Guard — Control‑Plane Safety installs like any other MCP skill: drop the folder into `~/.claude/skills/error-guard/` for global access, or `.claude/skills/error-guard/` to keep it scoped to one project. After a quick restart of Claude, you can trigger it explicitly with `/error-guard`, or let the AI decide when it's the right tool for your request.

Error Guard — Control‑Plane Safety has been installed 3,033 times, making it one of the more actively used skills in the Developer & DevOps category. The install rate suggests it solves a real, recurring need rather than a niche edge case. The source code is open on GitHub — you can inspect it, contribute fixes, or fork it to adapt the skill for your specific setup. Like all skills on DiscoverAISkills, it is free to install and use. The broader AI skills ecosystem continues to expand as developers contribute new capabilities across categories like developer tools, data analysis, writing, automation, and more.
