Simmer Market Maker

This skill is plausibly a market-maker and the code aligns with its stated purpose, but exercise caution before running it with a real API key: 1) The package metadata in the registry is inconsistent (missing required env, version mismatch) — ask the publisher or check an authoritative source. 2) Review the simmer-sdk package (source, publisher, permissions) before pip installing; consider installing into an isolated venv. 3) Test extensively in paper mode (TRADING_VENUE=sim or --dry-run) and don't run --live until satisfied. 4) Consider creating a scoped API key (if supported) with limited permissions and rotate it afterwards. 5) Inspect where the skill stores its config (simmer_sdk.skill.get_config_path) to ensure it doesn't expose secrets on disk. 6) If you lack confidence in the author, have a developer review the simmer-sdk and market_maker.py code paths that place/cancel orders (they use a private ._request method in places). These inconsistencies make the package suspicious but not demonstrably malicious; proceed only after the checks above.

Type: OpenClaw Skill Name: simmer-market-maker Version: 1.3.0 The skill is a legitimate market-making bot for Polymarket that uses the simmer-sdk to place and manage limit orders. It fetches market data from the Simmer API and live order book midpoints from the official Polymarket CLOB endpoint (clob.polymarket.com). The code in market_maker.py follows the strategy described in SKILL.md, includes appropriate safeguards against resolved markets or high slippage, and contains no evidence of data exfiltration, malicious execution, or prompt injection.
