TypeScript

Security checks for vulnerabilities and agentic risk

Overview

This is a TypeScript guidance skill with a small, disclosed preference-memory folder and no executable payloads or unrelated data access.

Before installing, know that the skill may keep TypeScript-related preferences and prior context in ~/Clawic/data/typescript/. This is useful for consistent advice, but review or delete those files if you do not want persistent personalization.

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 instructs the agent to read from and write to user-local preference files under ~/Clawic/data/typescript without any user-facing notice or consent step. Even though the stated purpose is personalization, silent access and modification of local data creates a privacy and integrity risk because the agent may persist user information or alter future behavior unexpectedly.
