Automates and verifies multi-step browser tasks through a clean Chrome CDP session; use when repeatable autonomous browser control is needed, not an already-open authenticated profile.
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 - self-healing LLM browser automation > **Keyword**: `browser-harness` · `self-healing browser` · `llm browser automation` · `cdp agent` > > Direct WebSocket connection between an LLM agent and Chrome via Chrome DevTools Protocol. The agent can inspect the page, write helper code, reuse domain skills, and verify the task without an extra browser abstraction layer. Browser Harness is the canonical replacement for the removed `agent-browser` skill in this catalog. Use it for clean browser verification, autonomous browser tasks, and platform-portable CDP control across Claude Code, Codex, Antigravity, Gemini CLI, and OpenCode. ## When to use this skill - The user needs an LLM agent to complete a multi-step browser workflow: login, navigation, form fill, data extraction, download, or verification. - The workflow needs a clean browser profile or repeatable CDP verification instead of the user's already-open browser state. - The user is running from Codex CLI or Antigravity and needs a local browser harness the agent can operate with shell/Python commands. - Claude reports image/screenshot/tool errors when browser screenshots are written, resized, or re-opened. …

How to install
mdr add akillness/jeo-skills/browser-harness@sha256:d2a7508827af18dfThe line at the top of this page pins the label v1.1.0, 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.
