Use when interacting with web pages, running manual E2E browser tests, testing UI flows, or inspecting live web surfaces via Playwright MCP. Employs text-first accessibility snapshots and element refs, network inspection, form filling, and custom Playwright script execution.
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-usage
Universal browser automation and verification skill using Playwright MCP (`@playwright/mcp`).
Operates on structured accessibility tree snapshots and element reference tokens (`[ref=eN]`),
enabling reliable interaction, inspection, and end-to-end verification without vision models.
## When NOT to Use
- Plain HTTP REST API calls or JSON fetching — use HTTP tools (`curl`, `web_extract`, `apiFetch`) instead of spinning up a full browser engine.
- Headless unit test runs in CI — use your framework's native test runner (`bun test`, `dotnet test`, `vitest`).
- Static documentation or source code queries — inspect local project files directly.
## Core Architecture: Text-First Accessibility Snapshots
Playwright MCP operates primarily on the browser's accessibility tree rather than raw pixel
coordinates or fragile CSS selectors:
1. **Snapshot**: `browser_snapshot` returns a hierarchical text tree of interactive and semantic elements:
```text
- heading "Dashboard" [level=1]
- textbox "Job Title or Keywords" [ref=e12]
- button "Search" [ref=e15]
- list:
- listitem:
- link "Senior .NET Engineer" [ref=e22]

How to install
mdr add arasz/ai-badger/browser-usage@sha256:4eac59436b817e24The line at the top of this page pins the label v1.0.0, 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.
