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

# AGENTS.md

Instructions for AI coding agents working with this codebase.

## Package Manager

This project uses **pnpm**. Always use `pnpm` instead of `npm` or `yarn` for installing dependencies, running scripts, etc. (e.g., `pnpm install`, `pnpm run build`).

## Code Style

- Do not use emojis in code, output, or documentation. Unicode symbols (✓, ✗, →, ⚠) are acceptable.
- In documentation and markdown, never use double hyphens (`--`) as a dash. Use an emdash (—) sparingly when needed. Prefer rewriting the sentence to avoid dashes entirely.
- CLI colored output uses `cli/src/color.rs`. This module respects the `NO_COLOR` environment variable. Never use hardcoded ANSI color codes.
- CLI flags must always use kebab-case (e.g., `--auto-connect`, `--allow-file-access`). Never use camelCase for flags (e.g., `--autoConnect` is wrong).

## Documentation

Do not hard-wrap prose in documentation files such as Markdown, MDX, and READMEs; let the editor or renderer wrap text naturally.

When adding or changing user-facing features (new flags, commands, behaviors, environment variables, etc.), update **all** of the following:
…

How to install

The exact contents, by fingerprint
mdr add vercel-labs/agent-browser/AGENTS.md@sha256:8da81b2b0c755d67

The line at the top of this page pins the label git:20261006.6d3e22c, 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.
