ThinkWiki

Security checks for vulnerabilities and agentic risk

Overview

ThinkWiki is a disclosed local knowledge-base skill with optional remote AI features, and the main user concern is choosing whether to send wiki content to configured AI providers.

Before installing, confirm you are comfortable with a local wiki tool reading and writing the wiki directory you choose. Do not set THINKWIKI_LLM_* or THINKWIKI_EMBED_* variables unless you are comfortable sending relevant content to that provider; override the default embedding URL if your data policy requires a different provider.

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
