Picks for EN posts/newsletters: prefer official sources, checkable engagement, useful for engineering decisions.

Today's must-reads

  1. Agent Skills foundation donation × Auto Mode default (see items 1–2). Same-day “open standard + default permissions” pair — interoperability vs mis-action surface.

  2. Decisions API GA × mammoth/elephant OSS (see items 3–4). Closed near-real-time decisions vs open probability deciders — unit economics and calibration.

  3. Claude Security continuous scan × formal-verification blog (see items 5–6). Safety agents from “find vulns” toward “prove properties.”
