Overview

This is a disclosed weather-market trading skill that defaults to dry-run mode but can place real Polymarket trades when explicitly run live.

Install only if you intend to give this skill access to Simmer account data and possible trading authority. Start with dry-run, keep small max-position and max-trades settings, protect or rotate the SIMMER_API_KEY, and enable --live, --quiet, cron, or --no-safeguards only after you understand the financial risk.

Missing User Warnings

Medium

• Confidence: 95% confidence
• Finding: The documentation says 'Execute real trades' for the --live flag, but it does not prominently warn that this submits actual market orders using real funds and can cause financial loss. In an automated trading skill, insufficient warning materially increases the chance of accidental execution by users who may treat command examples as safe to paste.
