Security Best Practices

Security checks for vulnerabilities and agentic risk

Overview

This skill is a transparent security-review helper that stores optional local review context only after user consent.

Install this if you want a reusable security-review workflow. Before enabling memory, decide whether you are comfortable storing review preferences, findings, and accepted-risk notes in ~/security-best-practices/; decline persistence if project security context should remain session-only.

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 invocation text says to activate when the user requests 'security guidance, hardening, risk triage, or remediation planning,' which is a broad natural-language condition rather than a specific trigger set. It does not provide exclusion conditions or negative examples, so ordinary requests for general guidance may overlap and cause unintended activation.
