Agentinel

Agentinel acts as a crucial security layer for autonomous coding agents, protecting against compromised npm packages. Key features include: * Interception of malicious npm packages * Integration at the hook level for pre-execution checks * Verification against a 60,000+ threat database * Local operation with zero cloud calls * Ultra-low latency scanning (under 2ms) This package guardrail prevents "slopsquatting" and other supply chain attacks where agents might hallucinate non-existent or dangerous packages. Agentinel scrutinizes every install request, scanning the full dependency tree, not just the primary package. By sitting directly between the coding agent and the terminal, it ensures no harmful bytes reach the disk. Agentinel provides an important defense mechanism by feeding structured JSON feedback directly back into the coding agent's context. This enables the agent to self-correct and avoid repeated errors without requiring human intervention. Additionally, its heuristic checks, which analyze factors like package age, download count, and publisher drift, help identify zero-day threats not yet listed in existing databases. This tool is ideal for developers and engineering teams utilizing autonomous coding assistants (such as Claude Code or Cursor) who need robust, real-time protection against package vulnerabilities and hallucinations, ensuring code integrity and system security.
