Ran actual browser-harness sessions against each site and rewrote
the skill files from live test findings. Key corrections:
GitHub: wait(2) after wait_for_load() for React hydration; search API
separate 10 req/min limit; search/code needs auth (401 unauthed)
HackerNews: athing also matches comment rows (use 'athing submission');
job posts break naive score-zip; html.unescape() required for titles
Amazon: .zg-item-immersion gone from Best Sellers; #priceblock_ourprice
returns null (legacy); review count selector collides with cross-sell
widget — use [aria-label*='ratings'] instead
News: The Verge is Atom not RSS (namespace dict required); Reuters
hard-blocks http_get with 403 even with User-Agent; BBC shows no
consent banner from US IP; parallel fetch is 4.3x faster (0.16s vs 0.70s)
ProductHunt: goto() ERR_ABORTED — always use new_tab(); /posts/ URLs
don't exist (it's /products/); homepage has 30 fixed items no lazy load;
[data-test^='post-item-'] is the correct card selector
