Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
browser-harness is a thin layer that connects agents to browsers via an editable CDP harness. # Code priorities - Clarity - Precision - Low verbosity - Versatility # Overview Core code lives in `src/browser_harness/`: - `admin.py` — daemon lifecycle, diagnostics, updates, profile management - `daemon.py` — the long-lived middleman process between the browser and the agent - `helpers.py` — CDP wrapper and core browser primitives auto-imported into the scripts the CLI reads from stdin - `run.py` — the `browser-harness` CLI `SKILL.md` tells agents how to use the harness and CLI. `install.md` tells agents how to install it, attach a browser, and troubleshoot. An agent operating the harness only edits inside `agent-workspace/`: - `agent_helpers.py` — task-specific browser helpers the agent adds - `domain-skills/` — skills the agent writes and reads Package/CLI name = `browser-harness`. Skill identity (`name` + trigger) = `browser-use` (do not rename). # Commands From a **git checkout** (no global install required for local testing): ```bash # doctor — install/daemon/browser state ./browser-harness --doctor …

How to install
mdr add browser-use/browser-harness/AGENTS.md@sha256:86dc889e7f18613cThe line at the top of this page pins the label git:20260831.a9c3192, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
