Work safely with AI agents like Claude Code, Cursor, Kiro
Agent Definition
# AgentGuard [](https://github.com/krishkumar/agentguard/actions) [](https://www.npmjs.com/package/ai-agentguard) [](https://www.npmjs.com/package/ai-agentguard) [](https://opensource.org/licenses/MIT) [](https://nodejs.org/) **Work safely with agents like Claude Code, Cursor, Kiro CLI.** AI coding agents are powerful, but with great power comes `rm -rf /`. I've been recommending tools like Claude Code and Cursor to junior devs and non-technical folks lately. These agents can execute shell commands autonomously, which is useful. But it also means a single hallucination could wipe their SSH keys, nuke a folder, or brick a meticulously created dev environment. Frontier models do come with guardrails, but I wanted control over project-specific no-nos too - like pushing to master or running that one script that drops the staging database. An LLM deciding whether a command is "safe" is probabilistic. I wanted something classical: a system where I define exactly what's allowed and what's blocked, with no ambiguity. Inspired by `.gitignore`: simple pattern matching, one rule per line, easy for anyone to read and modify. > Built with [Kiro](https://kiro.dev) for the Kiroween Hackathon 2025 ## Highlights - Deterministic rules, not probabilistic LLM guardrails - `.gitignore`-style syntax anyone can read - Recursive command unwrapping (catches `sudo bash -c "rm -rf /"`) - Catastrophic path detection (blocks `rm -rf /`, `rm -rf ~`, etc.) - Zero latency - all validation is local ### Supported Agents | Agent | Status | Install Command | |-------|--------|-----------------| | Claude Code | ✅ Supported | `agentguard install cursor` | | Cursor | ✅
