Agent Survival Kit

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small budgeting tracker that discloses its local file storage and does not ship executable code or hidden automation.

Install only if you are comfortable with an agent creating and updating local plaintext files that contain financial tracking data. Review the generated memory files if the workspace is shared or synced.

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
The skill explicitly states that it will create templates on first run and store financial data in workspace files, but the finding indicates the description lacks a clear warning about those file creations and modifications. This is a real transparency and consent issue: users or agents may invoke the skill without realizing it persists and alters local state, which can lead to unintended data retention or workspace changes.
