An AI coding agent guardrail — a CLI hook that blocks destructive git and filesystem commands and secret file access before they execute. Supports Amp Code, Antigravity CLI, Claude Code, Codex, Copilot CLI, Cursor, Gemini CLI, Hermes Agent, Kimi Code, OpenClaw, OpenCode, and Pi.

The vendor-neutral protocol for AI agent safety & security — and the neutral benchmark that ranks the vendors.

Don't let AI destroy your hard work! HardStop is a rock-solid protection for AI-generated commands. Pre-execution safety validation for Claude Code, Claude Cowork. Catches dangerous commands before they run: whether from AI mistakes, hallucinations, prompt injection, or misunderstood instructions. Seatbelts for the agentic AI era.

Stop AI agents from doing things you didn't ask for.

CLI tool to block --no-verify flag in git commands. Prevents AI agents from bypassing git hooks.

Runtime guardrails for Claude Code. Auto-approve what's safe, gate what's risky, block what's dangerous. Dual enforcement, full audit trail. MIT.

🪝 Claude Code hooks + an installable plugin marketplace: safety, cost, observability, productivity.

Deterministic runtime safety for AI agents: scan PII, gate tool actions, verify LLM output.
