DeepSeek published dsh-superagent, a research prototype of a proactive coding agent for one GitHub repository, packaged for DeepSeek Harness. When an allowed person asks for work in GitHub or, optionally, Feishu, it opens a work item, works in its own session and directory, and answers in the same conversation, for example with a pull request. A web panel shows what needs a person. DeepSeek says it is not production-ready.
agent-desktop, from Vercel Labs, is a command-line tool and C library for macOS, Windows and Linux. A snapshot returns JSON with a ref for every element an agent can act on; the agent acts on a ref, then snapshots again to check the result, with no pixel matching. When the UI changes, an action returns a stale-ref error instead of hitting the wrong element. By default, actions don't move the pointer or take focus.
Stageshow is a skill that agents such as Claude Code, Codex and Gemini read before making mock product interfaces and demo animations. The agent starts from the closest example, builds the demo, films it, then fixes what it finds, and the result is an ordinary React component. A playground shows the same demo done badly and done well side by side. Its author says most demos still take a few rounds of feedback.
