Weather temperature prediction market trading on Polymarket via Simmer SDK. Uses NOAA (US) and Open-Meteo ensemble (international) forecasts as signal, EV/Ke...
Usage Guidance
This package appears to be a genuine weather-market trading bot, but several inconsistencies should make you cautious: - Do not run with --live or provide API keys until you verify the code. The skill will make authenticated network calls to Simmer (and may interact with Polymarket) and can execute real trades. - The registry metadata incorrectly states there are no required environment variables; the repository (clawhub.json and scripts/status.py) expects SIMMER_API_KEY and SKILL.md expects TRADING_VENUE in a .env. Confirm which credentials are required and where they will be used before supplying secrets. - There is no explicit install spec even though clawhub.json lists a pip dependency (simmer-sdk). Expect to install external Python packages if you run the code; review the package(s) (simmer-sdk) separately for trustworthiness. - Inspect weather_trader.py (the long entrypoint) and any modules that call external APIs to confirm there are no unexpected endpoints or credential exfiltration. Check how Polymarket live mode is implemented and whether it requires additional tokens or wallet signing. - Run the code first in dry-run mode and with network blocked (or against a sandboxed / test account) to observe behavior and file writes (trades.jsonl, performance_snapshot.json) before connecting real funds. If you want, I can: (a) list all places in the code that read environment variables or make network calls, (b) search weather_trader.py for lines that perform live trades or call external endpoints, or (c) highlight exactly which files/lines reference SIMMER_API_KEY and TRADING_VENUE.
Capability Analysis
Type: OpenClaw Skill Name: yh-polymarket-weather-trader Version: 1.16.0 The skill bundle is designed for weather-based trading on Polymarket but contains logic that violates skill isolation and performs non-standard file operations. Specifically, 'trade_performance.py' and 'weather_trader.py' attempt to access files and modules in parent and sibling directories ('Path(__file__).parent.parent'), which allows the skill to read data (such as 'trades.jsonl') from other installed skills. Additionally, 'weather_trader.py' writes detailed trade logs to a hidden directory in the user's home folder ('~/.hermes/'), which is an unusual and potentially stealthy location for data persistence. While these features are presented as 'Smart Money' signal integration and cross-skill reporting, the intentional directory traversal and out-of-sandbox file writing constitute significant security risks in an agentic environment.

Capability Assessment
Purpose & Capability
The name, SKILL.md, and included Python modules (ev_calculator.py, bayesian_update.py, maker_taker_arbiter.py, weather_trader.py, etc.) are coherent with a Polymarket/Simmer weather-trading bot. Requiring a Simmer API key (present in clawhub.json and referenced by scripts/status.py) is appropriate for the stated purpose. The main mismatch: the registry-level 'Requirements' block above lists no required environment variables, while clawhub.json and the code expect SIMMER_API_KEY and a pip dependency 'simmer-sdk'.
Instruction Scope
SKILL.md instructs running the local Python entrypoint (dry-run or --live) and fetching forecasts and market data. That scope is consistent with trading. The instructions explicitly enable real trades when run with --live and reference .env variables (TRADING_VENUE). The SKILL.md and code will make authenticated network calls to Simmer (https://api.simmer.markets) and may interact with Polymarket when configured — this is expected but high-impact, so users must not run with --live until credentials and behavior are inspected.
Install Mechanism
There is no formal install spec in the registry (instruction-only), which is lower risk, but clawhub.json declares a pip dependency ('simmer-sdk') and environment tunables. That means installing the skill in practice will require fetching an external Python package even though the registry provides no install step. This mismatch is an incoherence to clarify (no arbitrary download URLs were found in the files).
Credentials
The code and clawhub.json reference SIMMER_API_KEY and SKILL.md references TRADING_VENUE/.env settings — these are proportional to a trading bot. However the top-level registry metadata claims 'Required env vars: none' and 'Primary credential: none', which is incorrect. Also SKILL.md mentions Polymarket live trading but the manifest does not declare any Polymarket credential variables; if Polymarket live trading requires additional credentials or wallet access those are not declared. The missing/incorrect declaration of required secrets is a red flag that should be resolved before use.
Persistence & Privilege
The skill is not force-included (always:false) and does not request system-wide persistent privileges. clawhub.json's automaton.managed: true and entrypoint are expected for a runnable skill. The skill writes/reads local files (trades.jsonl, performance_snapshot.json) which is consistent with a trading skill and declared behavior.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install yh-polymarket-weather-trader
  3. After installation, invoke the skill by name or use /yh-polymarket-weather-trader
  4. Provide required inputs per the skill's parameter spec and get structured output
