That day's lede
Anthropic narrowed Fable 5's biology-safety classifier on Aug 7 so it stops blocking benign questions — interpreting lab results, explaining symptoms, general biology homework — while continuing to fall back to Opus 5 on dual-use requests around virology, toxicology, and molecular design. In testing, biology-related fallbacks dropped by about 85%, with total fallback reductions of roughly 67% on Claude.ai, 55% on Cowork, 17% on Claude Code, and 7% on the Claude Platform. Anthropic says it consulted a range of internal and external experts before moving the classifier boundary.

Claude Code · v2.1.223 · Aug 6
The Aug 6 release lets admins allow or block whole GitHub orgs in marketplace settings via owner/* wildcards, adds a /teleport hint for continuing cloud sessions locally, folds /review into /code-review, and fixes a bug where tab- or invisible-Unicode-padded commands could hide part of themselves from permission prompts.
Claude Developer Platform · Aug 5
Announced Aug 5, Enterprise customers can route prompts and tool responses through their own security server for an allow/deny check before Claude ever sees them — spanning Claude chat, Claude Code, and Cowork, with shadow mode, gradual rollout, and compatibility with tools like Netskope and Zscaler.
