Security audit

grepwrapper

Security checks for vulnerabilities and agentic risk

Overview

The skill's code-search purpose is clear, but it installs an unpinned third-party GitHub package globally, which creates a mutable supply-chain and persistent executable risk.

Review the upstream grepwrapper repository before installing. Prefer a pinned commit or verified package release, avoid global installation where possible, and consider installing in an isolated or least-privileged environment because npm install and the resulting binary can execute local code.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
