Security audit

Phase 1 Esa Drafter

Security checks for vulnerabilities and agentic risk

Overview

This skill is a draft-report workflow for environmental site assessments and does not show hidden execution, persistence, or data-exfiltration behavior.

Use this as a drafting aid only. The skill asks for confidential property and transaction information, so provide only information appropriate for the ESA and keep final reliance, AAI compliance, conclusions, and signature with a qualified Environmental Professional.

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

Autonomous Decision Making

Medium
Category
Excessive Agency
Content
Document:
- Any deviation from E1527-21 (and why)
- Access limitations (areas not viewed, locked rooms)
- Reliance on user-provided data without verification
- Non-scope items the user excluded
- The EP's qualifications statement (placeholder for the signing EP's credentials)
Confidence
75% confidence
Finding
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
