Run persistent CDP sessions from JavaScript via the browser-harness-js CLI to automate, inspect, and script Chrome with a long-lived typed Session and preserved
The browser-harness-js skill provides a tiny server-backed CDP runtime and a CLI that evaluates JavaScript snippets against a persistent, fully-typed DevTools Protocol Session. The tool keeps a reusable session (and globals) across invocations so agents can drive navigation, DOM queries, screenshots, network interception, and multi-tab flows without re-establishing connections. Output is returned as raw values or compact JSON, and errors surface to stderr for easy automation.
Use this skill when you need reliable programmatic control of Chrome from an agent or script: cross-tab automation, DOM inspection, runtime evaluation, screenshot capture, or attaching to a running browser. It is ideal when maintaining state across calls matters (preserved session, event listeners, globals).
sdk/ (server, session, generated bindings)Works well with agents that can call CLIs and run short JS snippets (Claude Code, Cursor, Node-based agents) and with developer tooling that benefits from a persistent CDP connection.
