Poly Market Forecast

Unofficial helper for reading Polymarket market data and running lightweight analytical models. Designed for researchers and casual users who want a quick CLI-style probability check without leaving the chat.

Features

• Fetch current market odds and volume
• Pull historical price series for trend analysis
• Evaluate custom scoring expressions (e.g., avg(o1, o2) * 0.5)
• Output results as clean Markdown tables

Usage

Ask the assistant to:

• "Get me the current odds for [market slug]"
• "Plot a trend for [slug] over the last 7 days"
• "Run my custom model on [slug] with [expression]"

All commands use the built-in poly_eval helper, which safely evaluates arithmetic over fetched data.

Configuration

No API key required. Data is fetched from public endpoints. Network access only occurs when explicitly querying a market slug.

Security Notes

• Inputs are treated as untrusted data; only arithmetic is evaluated.
• No network requests are made unless a market query is issued.
• The evaluator is sandboxed to numeric operations only.

Examples

> poly_eval("avg(0.55, 0.61) * 100")
  58.0

Implementation

The skill uses a bundled Python script (poly_tool.py) that wraps a small evaluation engine. It keeps state between calls to improve forecast consistency (e.g., caching recent series). State is stored in a local JSON file in the skill directory.
