Tolerance Stackup

Security checks for vulnerabilities and agentic risk

Overview

This is a focused tolerance stack-up calculation skill with no bundled executable code, network access, persistence, credential use, or hidden high-impact behavior.

Installers should treat this as a calculation aid, not final engineering approval. Confirm all tolerance assumptions and avoid executing any local scripts/build_report.py unless it is a trusted script you intentionally provide, since that helper is referenced but not bundled.

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
