Grainger

Claude Code plugin: Grainger.com (US industrial MRO) product research — typeahead and category discovery from a script, price and spec verification from the signed-in browser. Encodes the mapped /ta/v3, /tap/v2 and __PRELOADED_STATE__ surfaces, the facet grammar that filters a category, per-branch stock counts across ~325 branches, and the three distinct ways Grainger refuses a request while returning HTTP 200.
