- **Cache diagnostics is out of beta on the Claude API** (Founder news, [Anthropic](https://cookiesforai.app/ai-news/anthropic), 23 SEP 2026): Cache diagnostics is out of beta on the Claude API and no longer needs a beta header. Requests opt in by including the diagnostics object. Why it matters: Teams on the Claude API can see why a prompt missed the cache without depending on a beta feature.

- **Gemini CLI closes an indirect prompt injection path** (Founder news, [Google](https://cookiesforai.app/ai-news/google), 23 SEP 2026): [Gemini CLI](https://cookiesforai.app/tools/gemini-cli) v0.61.0 prevents indirect prompt injection via build file modifications and untrusted flags.
