Security audit

Biomass

Security checks for vulnerabilities and agentic risk

Overview

This skill is a biomass-energy reference tool that only displays local educational text and does not show unsafe behavior.

This appears safe to install as a static reference skill. It runs a local shell script to print biomass-energy information, so users should treat the technical values as reference material rather than authoritative engineering advice for regulated designs.

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
