Code Reviewer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward code-review helper whose git and PR review behavior matches its stated purpose, with no hidden execution, persistence, or exfiltration behavior found.

Install only if you are comfortable having the active agent inspect the code, diffs, or PRs you provide. Avoid using it on proprietary or secret-containing changes unless your workspace and model/session policies allow that data to be reviewed.

A.I.G

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

Finding

The skill explicitly supports reviewing GitHub PR URLs and local git diffs, which can cause the agent to access and analyze repository contents that may be sensitive or externally sourced without any privacy, consent, or trust-boundary warning. This creates a data exposure risk: users may unintentionally disclose proprietary code, secrets in diffs, or fetch untrusted content for analysis under the assumption the skill is purely local and safe.
