aihot 2026-07-13 08:10 + buzzing.cc HN-translation feed: xAI's official Grok CLI v0.2.93 silently uploads working directory + ~/.claude.json + global AGENTS rules + 30+ Skill files + an API key on every turn via a side channel to a xAI Google Cloud bucket; xAI subsequently added a server-side toggle to disable codebase upload.
