not much happened today

**Harnesses, agent infrastructure, and the MCP protocol** are central themes, with emphasis on how **harnesses, sandboxes, filesystem access, skills, memory, and observability** shape agent UI/UX and runtime environments. Despite jokes about MCP's demise, it remains vital in production, notably used internally by **Uber** and supported by **Anthropic**. The **coding-agent stack** is evolving with **CursorBench** combining offline and online metrics to evaluate models on **intelligence and efficiency**, where **GPT-5.4** leads in correctness and token efficiency. Agent-assisted development is splitting between automation-heavy workflows and "stay-in-the-loop" tooling, with **OpenAI** advancing **Codex Automations** featuring worktree vs. branch choices and UI customization. The open agent platform **Hermes Agent v0.2.0** introduces full MCP client support, ACP server for editors, and expanded provider integrations including **OpenAI OAuth**.
