Datasheets Skill

Purpose

Extract structured, machine-readable specifications from component datasheet PDFs and make them available to analyzer skills. Works on whatever PDFs are downloaded under <project>/datasheets/ (downloads are owned by distributor skills like digikey, mouser, lcsc, element14).

Scope

This skill owns:

• Extraction schema — the canonical JSON structure for per-MPN specs. Versioned via EXTRACTION_VERSION in scripts/datasheet_extract_cache.py.
• PDF page selection — heuristics to pick pages most likely to contain pinouts, e-chars, applications, SPICE models.
• Quality scoring — weighted rubric (pin coverage, voltage ratings, application info, electrical chars, SPICE specs).
• Consumer API — helpers in scripts/datasheet_features.py for other skills to query specific fields (e.g., get_regulator_features(mpn), get_mcu_features(mpn)).
• Verification — consistency checks between extracted data and schematic/PCB usage.

Non-goals

• No PDF downloading. That is owned by distributor skills (digikey, mouser, lcsc, element14).
• No global library. Each project's extractions live in <project>/datasheets/extracted/. There is no shared cross-project cache.
