Deepagents Code Review

Security checks for vulnerabilities and agentic risk

Overview

This skill is a markdown-only Deep Agents code review checklist with no executable behavior or hidden authority requests.

Installers should treat this as a focused code-review aid. It may cause the agent to quote relevant snippets from code under review, so use it only where sharing those snippets in the conversation is acceptable.

Vulnerability Patterns

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
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
