Security audit

Superpowers Requesting Code Review

Security checks for vulnerabilities and agentic risk

Overview

This skill is a code-review workflow helper that asks an agent to inspect git diffs and report issues; I found no hidden install, persistence, credential, network, or destructive behavior.

Install this if you want an agent to request structured code reviews of repository changes. Expect it to read git diffs and possibly use a reviewer subagent, but the inspected artifacts do not show hidden execution, data exfiltration, persistence, or credential use.

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
Vulnerability Patterns
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Confidence
85% confidence
Finding

The description says to use the skill when 'completing tasks, implementing major features, or before merging,' which are broad, common workflow states rather than specific trigger phrases or constrained activation conditions. Without clearer boundaries or exclusion conditions, the skill could be invoked more often than intended across routine development work.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
75% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

- Give clear verdict

**DON'T:**
- Say "looks good" without checking
- Mark nitpicks as Critical
- Give feedback on code you didn't review
- Be vague ("improve error handling")
