Developer Onboarding Doc

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-template skill for developer onboarding and does not contain hidden execution, persistence, or data-exfiltration behavior.

Installers should treat this as a template-writing aid. Review generated onboarding docs before sharing because they can include internal operational links, contacts, on-call details, and local secret-handling instructions that may be sensitive in the wrong audience.

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

Confidence
60% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Finding

The manifest description says to use the skill when asked to write a "developer guide," "onboarding doc," "codebase orientation," or "getting-started guide," which are broad natural-language requests without clear scope limits or exclusion conditions. Because this is a manifest-style section, the lack of narrower activation constraints could cause the skill to match common documentation requests beyond the intended onboarding context.
