At WWDC 26, Apple introduced Core AI, the official successor to Core ML, a framework for running LLMs and generative models entirely on-device against Apple Silicon. And on the terms-of-service front, InfoQ reports that using Claude Fable 5 (or Mythos 5) on Amazon Bedrock now requires opting into provider data-sharing — prompts and outputs flow to Anthropic for 30-day retention with human review, a break from how earlier Bedrock models kept inference data isolated.","The rest of the day was Show HN agent-tooling: a wave of small, single-purpose utilities aimed at the same workflow most of us already live in. Persona.js open-sourced a framework-free, WebMCP-native agent UI library; Logslim compacts test/build output before an agent reads it; taste-ai packs per-session \"taste\" context; and a name.com CLI gives Claude Code and Codex a skill to manage DNS. The connective tissue is clear: the tooling layer is consolidating around agents as the primary user.","If there's a thread worth tracking, it's agent security and isolation — Cordium (a self-hosted, identity-based sandbox built on Kubernetes) and an industrial middleware that fronts PLC data behind REST/gRPC both lean into keeping infra secrets away from both developers and the AI agents acting on their behalf."],"highlights":["Apple unveils Core AI at WWDC 26 — the successor to Core ML, for on-device LLMs and generative AI on Apple Silicon.","Claude Fable 5 / Mythos 5 on Amazon Bedrock now
