Polyclaw

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Polymarket trading skill, but it asks users to put a raw wallet private key in the environment and perform persistent on-chain approvals without enough scoping detail.

Install only with a dedicated low-balance wallet and after inspecting the actual scripts and dependencies that will run under uv. Understand exactly what each approval permits, avoid storing valuable wallet keys in shell history or long-lived environment files, and plan how to revoke approvals after use.

Vulnerability Patterns
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

Finding

Output size or generation rate is not bounded. Unbounded output enables denial-of-service through resource exhaustion, log flooding, or context-window stuffing.
