Activity Monitor

Overview

Monitor and analyze trading activity on Polymarket including token merges, splits, and redemptions. Useful for tracking whale movements, detecting coordinated activity, and identifying market closing signals.

Security

This skill implements defense-in-depth measures against indirect prompt injection (Snyk W011):

  • Input Sanitization: All user-generated content (activity titles, market slugs) is sanitized using security.ts
  • Pattern Filtering: Known prompt injection patterns are removed (e.g., "ignore previous instructions", "system:")
  • Content Validation: Suspicious content with excessive special characters is flagged
  • Fail-Safe: Processing errors return original data rather than corrupting it

The skill fetches data from the trusted DOME API (api.domeapi.io) which provides structured activity data from the Polymarket protocol.
