Use when the user wants to find real public KiCad/EDA projects: reference designs, or boards using a given component, tag, license, author, or capability (pcb, schematic, bom, gerbers). Searches BoardRepo's public corpus and returns up to 20 board summaries per page (handle/slug, name, description, tags, license, capabilities, saves, stars, URL), ranked by popularity by default so the most-trusted boards come first; pass page for more, or sort:recent for newest. Query is free text plus optional qualifiers: component:esp32 tag:keyboard license:mit has:pcb author:handle. Free-text words are ANDed, so a specific multi-word query narrows fast: if it returns nothing, do not shave one word off and retry — cut straight to the SINGLE most distinctive term (the brand, chip family, or part number) before concluding no board exists. Weigh each result by its saves/stars and completeness rather than trusting it blindly. Do not use for general electronics theory, generic datasheet facts, or the user's own local or private design. Pass a result's handle/slug or URL to get_board; do not guess a handle/slug.
