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
# Chromium Browser Operate the configured Chrome DevTools MCP against the existing shared browser without disrupting unrelated tabs or authenticated state. This skill owns rendered browser UI interaction, inspection, automation, and verification through shared Chromium. When they fit, use search, fetch, APIs, CLIs, or connectors for retrieval. Use host native-app tools for non-browser UI. Do not use native-app tools as a fallback around this skill's shared-browser attachment, page-ownership, or privacy rules. If the user selects another available browser integration, follow its tool contract without mixing controllers. ## Environment Contract - Treat the bundled `scripts/chrome-devtools-mcp.sh` wrapper and the tools exposed in the current session as authoritative. The wrapper runs the globally installed `chrome-devtools-mcp` executable and sets flags, logging, and browser attachment. Do not run the MCP package directly. - The MCP attaches to an existing remote-debugging browser. Never launch a fallback browser or create another profile when attachment fails. …

How to install
mdr add paulrberg/agent-skills/chromium-browser@sha256:38d82ab5062cdec0The line at the top of this page pins the label git:20261019.e444ac2, 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.
