Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrow project-documentation helper that only creates or updates a disclosed PROJECT.md file, with no evidence of hidden execution or data exfiltration.

Before installing, confirm you want the agent to create or edit PROJECT.md in your project root. The skill appears low risk, but the package metadata hash/version mismatch is worth verifying with the publisher or registry if provenance integrity matters for your environment.

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

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.

## Anti-patterns

- Generating a generic template without asking what matters.
- Letting PROJECT.md go stale (no changelog, no notes log).
- Duplicating what the code already documents.
- Creating PROJECT.md in the wrong place (must be at project root).
