●SECURITY — Claude Security, which scans a connected GitHub repository and returns CWE-tagged findings with a suggested patch, now runs on the latest Mythos generation. It is in public beta for Enterprise plans●DESIGN — The reasoning behind it is worth noting: a capable model is riskiest with direct access, and constraining output to a fixed shape such as a patch or an alert lowers that risk considerably●COMMERCE — Anthropic published blueprints for commerce agents. Shopper-facing agents suggest and add to cart; merchant-facing agents advise on inventory and pricing. Neither completes the purchase●CLI — Claude Code v2.1.256 fixes launch failures on macOS 12 Monterey, along with errors in remote and scheduled sessions●AUTO — v2.1.257 adds a Containment Escape rule to auto mode, guarding against unauthorized cloud credential use and cross-tenant operations. If you live in auto mode, it is worth checking what now stops●LIMITS — The 50% weekly limit boost runs through September 13. From September 14 the permanent level is 25% above the pre-promo baseline, and this applies only to Claude Code weekly limits●SECURITY — Claude Security, which scans a connected GitHub repository and returns CWE-tagged findings with a suggested patch, now runs on the latest Mythos generation.
