## What it does

This skill connects your coding agent to live Polymarket data via public Gamma and CLOB APIs. All requests run read-only and require zero authentication. The skill will never execute trades for you, so every position must be placed manually.

Execution relies on four Python scripts. The `scripts/find_edges.py` tool scans active markets where YES and NO contract sums diverge from parity after deducting taker fees. To inspect market depth for a specific token, `scripts/analyze_orderbook.py` takes a `--token-id` flag to evaluate bid-ask spreads, imbalance ratios, and liquidity thickness.

For market movement, `scripts/momentum_scanner.py` spots markets where 24-hour volume exceeds the 7-day average. The bundle also provides `scripts/correlation_tracker.py`, which grades portfolio risk on a 0 to 100 diversification scale. Keep in mind that 5-minute and 15-minute crypto markets incur dynamic taker fees, which the scripts account for in breakeven calculations.

## When to use it
- detect underpriced and overpriced contract pairs across active markets
- calculate order book spread and bid-ask depth for a target token
- screen prediction markets for 24-hour volume surges
- score portfolio diversification from 0 to 100 to catch clustered exposure

## Example prompts
- Scan Polymarket for pricing discrepancies using scripts/find_edges.py
- Check the order book imbalance for --token-id <TOKEN_ID> with depth 10
- Run momentum_scanner.py to find recent volume surges above 10000
