Overview

This is a disclosed trading automation skill with real financial risk, but its sensitive behavior is aligned with its stated purpose and includes user-controlled live mode and risk limits.

Install only if you intend to run automated prediction-market trading. Start in dry-run mode, keep the default small trade limits until tested, use a restricted API key if Simmer supports it, and verify the local config and logs before enabling `--live` or cron scheduling.

Medium

• Category: MCP Least Privilege
• Confidence: 84% confidence
• Finding: The skill declares use of a high-value credential (`SIMMER_API_KEY`) and describes live trading behavior, but the metadata shown does not declare explicit permissions despite requiring environment access. This creates a transparency and governance gap: a user or platform may underestimate the skill's ability to read secrets and place trades, increasing the risk of credential misuse or accidental authorization of financial actions.
