Self-Evolving Harness

Security checks for vulnerabilities and agentic risk

Overview

This skill is only a short Markdown description and does not contain executable code, install logic, data access, or persistence behavior.

Installing this appears low risk from the submitted artifacts, but users should treat it as a very minimal, underspecified skill description rather than a complete harness until clearer runtime behavior and language support are documented.

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

Findings (1)

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The description includes substantive Chinese-language instructions/content in a mixed-language skill description, which creates a language/locale constraint without indicating that the user can choose another language. The policy requires flagging language-policy issues when a skill forces a specific language without user opt-in.
Content: No source excerpt is available for this finding.
