  Episode #30

  Restricted Mode, a Larger Context Ceiling, and the Pentagon Ruling

  Aug 31, 20267 min

  Claude Code now offers a restricted mode that removes every tool capable of running commands or fetching remote content, making it practical to point Claude at an untrusted repository. Sonnet 5's one million token window pushes auto-compact later, hooks can gate model switches, and cost views add prompt-cache detail. Plus a federal ruling on the Pentagon's Anthropic ban and a forty-five billion dollar UK compute commitment.

  Sessions That Resume Themselves

  Aug 24, 20266 min

  Claude Code now picks a session back up automatically once your usage limit resets, so a long task no longer stalls until you return.
