Quantitative Intelligence

Overview

A calculation bridge that connects all measurement sources to the project intelligence data store, with a complete cross-sheet reference index enabling multi-page calculations and spatial correlations.

What This Skill Does

1. Builds a Sheet Cross-Reference Index — Maps every detail callout, section cut, schedule reference, and spec reference across the entire plan set so Claude knows how sheets connect
2. Creates Assembly Chains — Links related elements across multiple sheets (e.g., footing plan view → section detail → structural notes → concrete spec) into calculation chains
3. Calculates Derived Quantities — Computes volumes, areas, lengths, and counts by pulling dimensions from multiple sheets through assembly chains
4. Merges Multiple Data Sources — Combines DXF geometry (exact), visual analysis (approximate), takeoff measurements (calibrated), and text extraction (parsed) with clear priority rules
5. Flags Discrepancies — When sources disagree by >10%, flags for superintendent review
6. Stores in Project Intelligence — All quantities go into plans-spatial.json with source attribution for downstream use by reports, dashboards, and briefs

Data Source Priority

When the same measurement exists from multiple sources, use the highest-priority source and note others as validation:
