Security audit

Critical Thinking

Security checks for vulnerabilities and agentic risk

Overview

This is a reasoning framework skill that teaches structured critical thinking and does not request system access, persistence, or automatic actions.

Installers should treat this as a thinking aid, not a source of truth. It can help structure high-stakes analysis, but users should still verify facts and sources before making consequential decisions.

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
Vulnerability Patterns
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Autonomous Decision Making

Medium
Category
Excessive Agency
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.

## Red Flags

- Only one hypothesis is being considered
- "Supporting evidence" accumulated without checking against alternatives
- Conclusion reached before the analysis (motivated reasoning)
- No matrix or equivalent structured comparison exists
- No statement of linchpin assumptions / what would change the conclusion
