## Worth attention

- **Gemini Deep Research**
  https://ai.google.dev/gemini-api/docs/deep-research?hl=ko
  Google added a preview Gemini Deep Research agent in the Interactions API with background execution, collaborative planning, visualizations, and MCP support.
- **I Slop Forked Neon. You Should Too.**
  https://neon.com/blog/slop-fork-neon
  Neon shows an agent-built clone of its console running on the public API and SDK, arguing that APIs, CLIs, and MCP matter more than dashboards for agents.
- **What we learned mapping a year's worth of AI-enabled cyber threats**
  https://www.anthropic.com/news
  Anthropic posted a new policy note on AI-enabled cyber threats, but the article detail page was unreadable in the approved browser toolchain, so this stays watch-only.
