commit 64d6800e66d1b2dc33ec95ab88b7a1b55d48396c equwal <13551856+equwal@users.noreply.github.com> 2026-09-22 22:39:40 -0700 Add the browser-driver agent and its browser The browser-driver agent does the browser steps of a handoff and stops at the first human step. It ends with one JSON object: done, ready, or not_done with the error. SKILL.md tells the calling agent what to do with each status. The agent works in its own browser. "handoff.py browser" starts Brave or Chrome with a separate profile and the remote debugging port 9333. The plugin starts Playwright MCP 0.0.82 with npx. Playwright MCP controls the browser through that port. Thus the agent works behind other windows and fills in file dialogs without the mouse. The agent uses Windows-MCP only for windows of the operating system. The agent gets only tools that look at the page and act on it. Tests check the tool list, the names of the MCP tools, the list of human steps, and the launcher.
