pi-browser-harness

Direct browser control via CDP. Use when the user wants to automate, scrape, test, or interact with web pages. Connects to the user's already-running Chrome. Default to browser_snapshot for understanding pages and browser_execute_js for surgical reads — browser_screenshot is for visual verification only.

Use when the user asks you to research a topic on the web, do deep research, investigate something across multiple sources, or produce a cited report / literature review from the live web. Decomposes the question, fans out isolated web-search-researcher subagents (one per sub-question) that scrape the real browser, then synthesizes a source-cited Markdown report. Trigger phrases include "research", "deep research", "look this up and cite sources", "investigate", "compare X and Y with sources".
