Credibility Action Gate

Security checks for vulnerabilities and agentic risk

Overview

This skill is an analysis-only credibility gate that reads local JSON evidence and produces a local disposition without taking external action.

Installers should understand that this skill can influence whether an agent proceeds with costly or reputation-sensitive actions, but the artifacts keep that decision bounded to local analysis and require the operator's own policy for authority limits.

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
