Ultra-fast, zero-dependency safety guardrails for AI agent tool calls to prevent unauthorized execution.
Vigil addresses a critical vulnerability in modern AI agents: the risk of 'prompt injection' or 'jailbreaking' leading to unauthorized tool execution. As agents gain the ability to interact with external APIs, databases, and file systems, securing these endpoints becomes paramount. Vigil provides a robust validation layer that sits between the LLM and the tool execution environment. Built with TypeScript, it is engineered for extreme performance, boasting a sub-2ms processing time that ensures real-time responsiveness.
The framework is designed with a zero-dependency philosophy, making it highly portable and easy to integrate into diverse environments, from serverless functions to edge computing. It supports complex policy enforcement, allowing developers to define strict schemas and allowlists for tool arguments. By validating inputs before they reach the execution layer, Vigil effectively mitigates risks like remote code execution, unauthorized data exfiltration, and unintended system modifications, making it an essential component for enterprise-grade AI agent deployments.
