Personal Knowledge Architect — Build Connected, Reusable Knowledge

Security checks for vulnerabilities and agentic risk

Overview

This skill is a Markdown-only personal knowledge organization workflow that writes user-directed YAML outputs and does not request hidden access, persistence, network execution, or elevated privileges.

Before installing, be aware that the skill is meant to read personal source texts and create or update YAML/progress files in a directory you choose. Use it only with texts and output folders you are comfortable having organized by the agent.

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

Whitespace Padding

Medium
Category
Prompt Injection
Confidence
70% confidence
Finding

Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.

definition has a source and stays within 50 words; there are no isolated concepts; and every concept
has two to six relations.

dependency.
