Inspects live web pages through the Chrome DevTools Protocol with the `bdg` CLI: targeted DOM queries, computed styles, layout debugging, and raw CDP calls, without loading a full page snapshot. Trigger on: "inspect element", "check computed styles", "query the DOM", "debug layout".

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-debugger-cli (bdg)

## When to use
- Query specific DOM elements or attributes
- Run targeted CDP methods without full page snapshots
- Debug with minimal token overhead
- Prefer it over chrome-devtools-mcp for token efficiency; fall back to the MCP when `bdg` can't do the job

## Prerequisites
- Install: `npm install -g browser-debugger-cli@alpha`
- Chrome available locally, or connect via `--chrome-ws-url`

## Common workflow
1. Start a session:
   - `bdg http://localhost:3000`
2. Query DOM:
   - `bdg dom query "button"`
   - `bdg dom query "[data-testid='x']"`
3. Discover CDP methods:
   - `bdg cdp --list`
   - `bdg cdp --search dom`
4. Evaluate JS:
   - `bdg cdp Runtime.evaluate --params '{"expression":"document.title"}'`
5. Stop the session:
   - `bdg stop`

## Notes
- Use `bdg status` or `bdg peek` to inspect without stopping.
- Use `bdg --no-headless` when you need a visible browser window.

How to install

The exact contents, by fingerprint
mdr add jerseycheese/agent-skills/browser-debugger-cli@sha256:8967806a7601a48e

The line at the top of this page pins the label git:20261016.04e815b, 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.
