contract-red-flag-scanner

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent offline contract text scanner with no hidden network, persistence, or destructive behavior found.

Before installing, understand that this tool processes contract text locally and may help spot common red flags, but it is pattern-based triage and not legal advice; for high-value contracts or serious findings, consult a licensed attorney.

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

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.

Disputes in their state. For consumer contracts this usually makes enforcement
impractical both ways — but it's their waiver, not yours.

### ASSIGNMENT WITHOUT CONSENT (LOW)
They can transfer your contract to anyone (collections firm, new property
manager); you usually can't. Fair version: consent not to be unreasonably
withheld, both directions.
