FDE Engagement Charter

• Outcome: Pass
• Latest audit: Sep 16, 2026 · 10:46 AM UTC
• Version: 1.0.0

Overview

This skill is a scoped POC charter-writing aid with a local structural validator and no evidence of hidden execution, persistence, exfiltration, or destructive behavior.

Install only if you want an agent to help draft and check POC charter documents. The main practical consideration is that charters may mention customer data, system access, owners, and risks, so review outputs before sharing and do not treat the validator as proof of actual business, technical, legal, or security approval.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Vulnerability Patterns

• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code

After drafting, run `node scripts/validate-charter.js <poc-charter.md>` to check objective, success criteria, scope, ownership, data, timeline, risk, and decisi

Autonomous Decision Making

Medium

• Category: Excessive Agency
• Confidence: 80% 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.

## Background

Problem discovery and confirmation: retrieving data and drafting billing-ticket responses take too long, and the reference to old policies results in rework. Customers are not allowed to automatically send or close tickets.

## POC decision problem

Scope Creep

Low

• Category: Excessive Agency
• Confidence: 70% confidence

Finding

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
