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

# CLAUDE.md

Browser automation for AI agents and humans.

## Key Docs

- ROADMAP.md — Future features (not yet prioritized)
- docs/reference/WebDriver-Bidi-Spec.md — BiDirectional WebDriver Protocol spec

## Current Goal

V1 shipped. Focus on fixing critical bugs and issues reported by users.

See open issues: https://github.com/VibiumDev/vibium/issues

## Tech Stack

- Go (vibium binary)
- TypeScript (JS client)
- Python (Python client)
- WebDriver BiDi protocol
- MCP server (stdio)

## Design Philosophy

Optimize for first-time user/developer joy. Defaults should create an "aha!" moment:
- Browser visible by default (see what the AI is doing)
- Screenshots save to a sensible location automatically
- Zero config needed to get started

Power users can override defaults (headless mode, custom paths, etc.) when needed.

## Rules

- Client library launch code must not shell out to vibium subcommands other than `pipe` — `pipe` ensures the browser is installed itself (#312). User-facing CLI install passthroughs are the one exception.
- Prioritize bug fixes over new features
- Run tests before committing: `make test`

How to install

The exact contents, by fingerprint
mdr add vibiumdev/vibium/CLAUDE.md@sha256:423e42933f1a6626

The line at the top of this page pins the label git:20260910.e557d33, 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.
