Security audit

Semantic Walk

Security checks for vulnerabilities and agentic risk

Overview

This skill does not run code or access data, but it can switch the assistant into an under-scoped alternate mode without clear opt-in or safety boundaries.

Review this skill before installing if you want predictable, direct assistant behavior. It appears suitable only for deliberate creative exploration; users should invoke it explicitly, stop it when they need factual or task-focused help, and avoid using it for sensitive, safety-critical, legal, medical, financial, or security decisions unless normal safeguards and direct-answer behavior are clearly preserved.

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 document promotes a gradual, stepwise process for making currently inaccessible content become visible, which is a classic setup for incremental elicitation. Even without explicit malicious payloads, this structure can be repurposed to slowly guide the model toward disallowed content, reduced skepticism, or disclosure that might not be produced through direct prompting.

Finding

The 'walker mode' framing explicitly tells the model to shift from normal assistant behavior into an alternative operating posture where it is meant to inhabit a conceptual role and reach otherwise inaccessible perspectives. Role-based state shifts are risky because they can be used to bypass default caution, justify unusual outputs, or reframe prohibited assistance as part of the mode.

Finding

The invocation guidance is loose enough that many ordinary user statements about exploration, insight, or 'walking somewhere' could be treated as activation cues for the skill. That ambiguity increases the chance of unintentional mode switching into a less bounded interaction style, which can weaken consistent application of normal safety and task framing.

Finding

Allowing walker mode to activate implicitly removes a clear boundary between ordinary assistance and the alternative role-like mode. That makes prompt interpretation less predictable and creates an opening for adversarial or accidental prompting to steer the model into behavior framed as 'navigating' rather than safely answering within standard constraints.
