SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill standardizes the practice of cross-checking macroeconomic data by enforcing cross-source validation from at least three independent sources to prevent hallucination.

Core Features & Use Cases

  • Three-source cross-verification: ensures data from multiple independent sources agree within ±1%.
  • Official and secondary sources: requires at least one primary source and cross-checks with trusted aggregators.
  • Use Case: when collecting index values, rates, or FX quotes, run three parallel searches and validate results before use.

Quick Start

Read this document and directly call the mcp_websearch_web_search_exa tool to perform three-source cross-checks and extract validated data.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I cross-verify macroeconomic data from multiple web sources?▼

Three-source cross-validation enforces ±1% consistency across independent sources to prevent hallucination. It applies to indices, interest rates, and FX quotes by running parallel web searches, requiring at least one primary source and returning structured output with source metadata.

What is the best way to prevent data hallucination when collecting FX quotes and interest rates?▼

Prevent data hallucination by enforcing cross-source validation from at least three independent sources before use. This ensures data from multiple sources agree within a ±1% tolerance, requiring original-text quotes and date-consistent search results for indices, rates, and FX quotes.

Can I validate index values using web search without writing custom cross-check scripts?▼

Yes, you can validate index values by directly calling the web search tool to perform three-source cross-checks. The skill standardizes cross-checking by enforcing ±1% cross-source consistency and returning structured output including source metadata.

Does macroeconomic data verification require a primary source or are aggregators sufficient?▼

Macroeconomic data verification requires at least one official primary source, cross-checked against trusted secondary aggregators. This three-source approach ensures indices, interest rates, and FX quotes are validated within ±1% consistency before extraction.

What are the limitations of three-source cross-validation for web search data?▼

Three-source cross-validation is limited by its ±1% consistency tolerance and dependency on date-consistent search results. It is specifically scoped to indices, interest rates, and FX quotes, requiring original-text quotes rather than derived or calculated figures.
