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

## gsd-browser

Native Rust browser automation CLI for AI agents. Controls Chrome/Chromium via CDP with a persistent background daemon. Supports navigation, element interaction (click, type, fill), snapshots with versioned refs, assertions, form analysis, structured data extraction, visual regression testing, network mocking, device emulation, auth vault, and prompt injection scanning.

### Quick Start

```bash
gsd-browser navigate https://example.com
gsd-browser snapshot
gsd-browser click-ref @v1:e1
```

### Installation

```bash
curl -fsSL https://install.gsd.build/browser | bash

# or from a repo checkout
cargo install --path cli
```

Requires Chrome or Chromium. The installer reuses a system browser when present and downloads Chromium automatically where Chrome for Testing is available.

### Full Reference

See [SKILL.md](./SKILL.md) for complete command reference (63 commands), workflow patterns, configuration, and examples.

How to install

The exact contents, by fingerprint
mdr add skillmds/skillmd/plugins/agents-mcp/skills/gsd-browser/AGENTS.md@sha256:70508b1d29243485

The line at the top of this page pins the label git:20260919.fecc0d5, 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.
