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.
3x in 3 months: Cursor @ $28b, Cognition + Windsurf @ $10b

Cursor is reportedly fundraising at a $28 billion valuation with $1 billion ARR, while the combined Cognition+Windsurf entity is fundraising at a $10 billion valuation after acquiring Windsurf remainco for $300 million. The competition between AI coding agents intensifies as Cursor focuses on Async SWE Agents and Cognition+Windsurf acquires an agentic IDE. Alibaba's Qwen3-Coder gains widespread adoption for coding tasks and integration into tools like Claude Code and LM Studio. OpenAI rolls out ChatGPT Agent to all Plus, Pro, and Team users, sparking discussions about an "agentic economy" emphasizing AI literacy. Anthropic's Claude Code is praised as a premier development tool with active community feedback. Perplexity's Comet browser assistant receives positive reviews and new feature showcases. The debate continues on whether AI coding tools will replace developers, with critiques highlighting the ongoing human effort required. A new minimalistic software engineering agent, mini, achieves 65% on SWE-bench with just 100 lines of code.
