Electronics Industry Sites Skillpack
Public Made by Adomby adom
One skill per popular electronics-industry website (ST, TI, Mouser, DigiKey, SnapEDA, Ultra Librarian, Arrow, Analog, Microchip, Nordic, CSE, Octopart, JLCPCB, datasheets.com): which access lane works (fetch, curl, pup, nb, API), the bot defense each one runs, the exact failure signatures, and the task recipes. Verified live, dated, and built to grow.

See the chip-fetcher page: https://wiki.adom.inc/john/chip-fetcher--## Per-website sub-skills — grow coverage for the whole industry--Each popular electronics site gets **one sub-skill** under `skills/<site>/SKILL.md` (NOT a separate-wiki page). A site sub-skill captures: the search/parametric URL patterns, how to extract results-from its DOM, login/cookie notes, whether pup is blocked, and the category-drill for parametric-families.
