Friday roundup: 30 Oct 2026

Anthropic released Claude Code 2.1.314 on 30 Oct 2026, adding a permissions.blockWritesOutsideWorkingDirectories setting that makes Write, Edit and NotebookEdit refuse any path outside working directories in every permission mode. The same roundup covers Anthropic's beta usage and cost analytics API, released 29 Oct 2026 behind the analytics-usage-cost-2026-08-24 header, and a raise of the Messages and Token Counting API maximum request size from 32 MB to 128 MB on 28 Oct 2026, while OpenAI shipped Codex CLI 0.166.0 on 29 Oct 2026 with GPT-6.1 Terra added to its bundled, Vertex AI and Amazon Bedrock model catalogs. The changes matter most to teams running Claude Code unattended or in CI, which should enable the write setting and handle claude -p now exiting 1 when startup fails, and to teams routing Codex models through Vertex AI or Amazon Bedrock.

GPT-6.1 Terra is added to the bundled, Vertex AI and Amazon Bedrock model catalogs. There is also codex invoke --resume for unloaded threads, clearer explanations when a request is blocked for safety reasons with safer follow-up prompts, and codex doctor --network-only for config, connectivity and WebSocket checks.Fixes keep approval and permission settings and reasoning-token accounting across resume and fork, so threads don't compact early, and TUI reconnection is more robust. Who it affects Teams that route models through Vertex AI or Amazon Bedrock, who can now select GPT-6.1 Terra inside Codex, and anyone resuming or forking long-running threads.
