Pfmea Process Fmea Drafter

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only PFMEA drafting skill whose safety-related instructions are disclosed and aligned with its quality-engineering purpose.

Before installing, users should understand that this skill can help draft a PFMEA but does not replace the responsible engineer, cross-functional team, customer requirements, or regulatory review; avoid sharing proprietary process data unless that is appropriate for the environment where the skill runs.

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

  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Finding

Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.

| Score | Severity (effect at end customer) | Occurrence (cause, given current prevention) | Detection (current detection control) |
| --- | --- | --- | --- |
| 10 | Safety / regulatory non-compliance without warning; impossible to escape | Very high — predicted in operation, no controls or controls ineffective | No detection method — cause / FM not detectable until use |
| 9 | Safety / regulatory non-compliance with warning | High — predicted often | Detection very unlikely, low-confidence sampling |
| 8 | Loss of primary function; major customer dissatisfaction | Predicted occasionally | Indirect detection of the FM, not the cause |
| 7 | Degradation of primary function | Predicted infrequently | Visual / manual inspection of cause |
