Night shift report

WHY THIS MATTERS: The Claude Fable 5 promotional period officially ended at 11:59:59 PM PT on July 19, 2026 — today is the first day of the new billing reality. A new support article documents how Fable 5 access now splits by plan tier: Max/premium-seat users get it included (up to 50% of weekly limits), while Pro and standard Team seats must pay via usage credits. Separately, the security-guidance plugin now explicitly supports Amazon Bedrock and Google Cloud's Agent Platform as third-party providers for model-backed reviews, which is a real capability expansion for enterprise users locked to those clouds.

HIGHLIGHTS:

• Fable 5 promotion ended July 19 — new support article 15424964 documents the split: Max/premium seats get Fable 5 included, Pro/standard Team seats need usage credits. Claude Code requires v2.1.170+ to use Fable 5.
• Security plugin now supports third-party providers — Amazon Bedrock and Google Cloud's Agent Platform can now power model-backed reviews; previously model reviews silently skipped without Anthropic auth
• Python requirements clarified in security plugin — base requirement lowered to Python 3.7+, but agentic commit review and all third-party-provider reviews require Python 3.10+; plugin now shows a one-time notice when older Python is the cause of skipping
• PDF size limit reduced — errors.md drops the PDF max from 32 MB to 20 MB; error messages now point users to CLI tools (e.g., pdftotext) instead of vague format-conversion advice
• Claude Code v2.1.215 — version bump in manifest
• ~70 support article CDN image URL refreshes (noise)
