Historical Trades Skill
Fetch and analyze historical trade data from Polymarket via the DOME API.
Security
This skill implements defense-in-depth measures against indirect prompt injection (Snyk W011):
- Input Sanitization: All user-generated content (trade titles, token labels, 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 trade data from the Polymarket protocol.
