Security audit

Polymarket Longshot Bias Trader

Security checks across malware telemetry and agentic risk

Overview

This is a disclosed prediction-market trading skill that defaults to paper trading and only makes live trades when explicitly run with the live flag.

Install only if you are comfortable giving this skill a Simmer trading API key. Start in paper mode, keep position limits low, review the broad market scope, and enable --live only if you accept the risk of real financial loss.

Missing User Warnings

Medium
Confidence
89% confidence
Finding
The manifest declares a required API credential (SIMMER_API_KEY) but provides no user-facing disclosure about what the credential is used for, what operations the skill will perform with it, or whether it can place trades or access account data. In a trading-related skill, silent credential use increases the risk of users granting high-value account access without informed consent, which can lead to unauthorized trading activity or exposure of sensitive account information if the entrypoint behaves unexpectedly.
