Meanwhile Agent Skills moved to a neutral foundation and OpenAI added a 12-hour cache and a second cloud. I'd spend this week pinning SDKs, auditing the gateway and dependency path, and keeping a provider abstraction so the next channel or version change stays out of business code. 1. Claude API ships 2026-10-21, its first new version since 2023-06-01: temperature, top_p and top_k now return errors, and new major SDKs move to Apache 2.0 2. LiteLLM 1.107.0 was a poisoned release: malicious code ran through Python startup hooks and stole credentials without LiteLLM ever being imported 3. Anthropic donates the Agent Skills standard to the Linux Foundation's AAIF: more than 70 agent platforms, about 1 million skills published and nearly 280 million installs 4. OpenAI adds 12-hour prompt caching to the API, with writes at 2.5x the input price 5. GitHub package firewall enters public preview, screening npm traffic between coding agents, CI and the registry 6. OpenAI's frontier models and Codex workflows are coming to Google Cloud through Model Garden and Google Cloud Marketplace
