Security audit
Premortem
Security checks for vulnerabilities and agentic risk
Overview
This skill is a disclosed reasoning checklist that does not install code, access data, call networks, or persist beyond normal always-loaded skill behavior.
Before installing, understand that this skill will broadly influence the agent's reasoning style by adding a silent pre-action risk check. That is consistent with its stated purpose, but users who want minimal always-on behavioral changes may prefer to disable automatic activation if their environment supports it.
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
- 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
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
