Trades monotonicity violations in NHL hockey O/U market ladders and spread-vs-total consistency on Polymarket. Each game spawns multiple O/U lines that must...
Usage Guidance
This skill appears internally consistent for Polymarket ladder arbitrage: before using it with real funds, (1) keep it in paper mode (default) and test thoroughly, (2) review the simmer-sdk package source and verify it is trustworthy, (3) treat SIMMER_API_KEY as sensitive — only provide a key with the minimum necessary permissions and consider using a segregated account/limited-balance API key for live testing, (4) inspect the remainder of trader.py (the file was truncated in the bundle listing) to confirm there are no hidden network endpoints or data-exfiltration paths, and (5) only run with --live once you understand the sizing and risk parameters configured in the tunables.
Capability Analysis
Type: OpenClaw Skill
Name: polymarket-ladder-nhl-hockey-trader
Version: 0.0.3
The skill bundle implements a legitimate NHL hockey arbitrage strategy for Polymarket, focusing on monotonicity violations in Over/Under ladders. The code in trader.py uses the simmer-sdk for market interaction, includes clear safety mechanisms (defaulting to paper trading), and lacks any indicators of data exfiltration, malicious execution, or prompt injection.

Capability Assessment
Purpose & Capability
Name/description claim to find monotonicity and spread-vs-total violations on Polymarket and trader.py implements market discovery, parsing, ladder grouping, checks, ranking, and trading via a SimmerClient. The required credential (SIMMER_API_KEY) and use of a Polymarket/sim venue are coherent with the trading purpose.
Instruction Scope
SKILL.md and the code limit actions to market discovery, parsing, consistency checks, ranking, and executing trades via the Simmer SDK. The instructions and code read only expected environment variables/tunables and do not instruct reading unrelated system files, scanning user data, or calling unexpected external endpoints in the provided code excerpt.
Install Mechanism
There is no custom download/install script in the bundle, but clawhub.json declares a pip dependency: simmer-sdk. Pip packages are common for this purpose, but they run code during install and their provenance should be verified (check the package source/repository and trustworthiness) before installing in a sensitive environment.
Credentials
The skill requires a single credential: SIMMER_API_KEY, which is appropriate for a trading client that executes orders. The script also reads tunables via environment variables (SIMMER_*), which are declared in clawhub.json. The credential is high-value (trading authority) but proportionate to the stated functionality.
Persistence & Privilege
The skill is not always-enabled, autostart is false, and cron is null. The automaton entrypoint is the script but default behavior is paper trading and nothing runs automatically until explicitly started; the skill does not appear to modify other skills or system-wide settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install polymarket-ladder-nhl-hockey-trader - After installation, invoke the skill by name or use
/polymarket-ladder-nhl-hockey-trader - Provide required inputs per the skill's parameter spec and get structured output

SDK resilience: try/except runt apply_skill_config
v0.0.2
fix: add _client.live=True so --live actually routes to polymarket-venue for real USDC trades
v1.0.1
Fix apply_skill_config AttributeError for new Simmer SDK compatibility
v1.0.0
- Initial release: trades monotonicity violations in NHL hockey O/U ladders and spread-vs-total inconsistencies on Polymarket.
- Automatically discovers, parses, and groups O/U and spread markets for each NHL game.
- Detects broken probability curves—buys/sells where O/U ladder or spread-vs-total is mathematically inconsistent.
- Tunable risk and market filters included; supports live or paper trading via Simmer UI.
- Designed as a template for further strategy extensions, e.g., other leagues or live data feeds.
