Description
Find odds divergence between sportsbook consensus and Polymarket sports markets, then trade the gap.
Usage Guidance
This skill is functionally coherent but exercise caution before installing and giving it live credentials. Prior to enabling LIVE=true or adding your SIMMER_API_KEY to a production agent: 1) Review the Simmer account/API key permissions — ensure the key scope is limited and use a dedicated account if possible. 2) Start with dry-run (LIVE unset or false) and observe several cycles to confirm matching and trade logic. 3) Inspect the included Python files (there are duplicate copies and some truncated/buggy-looking code fragments/typos) — run static tests and unit tests locally to ensure behavior matches expectations. 4) Confirm which clawhub.json/cron will be used (there are conflicting cron entries) so you know when the skill will run automatically. 5) Consider rate limits for The Odds API (free tier) and monitor for unexpected HTTP errors. If you are not comfortable reviewing code or limiting API key privileges, do not provide the SIMMER_API_KEY to this skill or enable LIVE mode.
Capability Analysis
Type: OpenClaw Skill
Name: polymarket-sports-edge
Version: 1.2.0
The skill is a sports betting arbitrage tool designed to trade odds divergence between Polymarket and traditional sportsbooks. The logic in 'sports_edge.py' uses The Odds API and the Simmer SDK to identify mispriced markets and execute trades based on user-defined thresholds. The code is well-documented, lacks obfuscation, and contains no evidence of data exfiltration, unauthorized access, or malicious intent.
Capability Assessment
Purpose & Capability
The skill claims to compare The Odds API prices to Polymarket via the Simmer SDK and to trade when a divergence threshold is met. The declared dependencies (simmer-sdk, requests) and required env vars (SIMMER_API_KEY, THE_ODDS_API_KEY) are exactly what you would expect for that behavior. No unrelated services or credentials are requested.
Instruction Scope
SKILL.md instructs only to fetch sportsbook odds and Simmer/Polymarket markets and run trades (dry-run by default). It does not instruct reading unrelated files or exfiltrating data. However the instructions assume the Simmer API key can be used to place orders: that is sensitive (financial) functionality and should be confirmed with the user before enabling LIVE mode.
Install Mechanism
No external binary downloads or archive extraction are used. Runtime requires pip packages (simmer-sdk, requests) declared in clawhub.json — a low-to-moderate risk install path consistent with the skill's purpose.
Credentials
Only SIMMER_API_KEY and THE_ODDS_API_KEY are required; optional env vars control thresholds and dry-run vs live behavior. These credentials are proportional to the purpose, but SIMMER_API_KEY grants the ability to transact on the user's account (potentially with real funds), so its privileges should be explicitly checked before enabling live trading.
Persistence & Privilege
The packaging includes automaton/managed entrypoint configuration and a cron schedule (so the skill can run periodically). There are two clawhub.json files with different cron schedules (root: "0 * * * *" vs nested: "55 * * * *") and mismatched metadata versions (1.1.0 vs 1.2.0). These inconsistencies suggest sloppy packaging and make it unclear how/when automated runs will occur — important because automated runs can place trades.
