agent-browser is agent-read markdown (skill) from rudycity/superagent: Browser automation CLI for AI agents. Use when the user needs to interact with websites, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or automating any browser task. Triggers include requests to "open a website", "fill out a form", "click a button", "take a screenshot", "scrape data from a page", "test this web app", "login to a site", "automate browser actions", or any task requiring programmatic web interaction.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# agent-browser
Fast browser automation CLI for AI agents. Chrome/Chromium via CDP with
accessibility-tree snapshots and compact `@eN` element refs.
Install: `npm i -g agent-browser && agent-browser install`
## Start here
This file is a discovery stub, not the usage guide. Before running any
`agent-browser` command, load the actual workflow content from the CLI:
```bash
agent-browser skills get core # start here — workflows, common patterns, troubleshooting
agent-browser skills get core --full # include full command reference and templates
```
The CLI serves skill content that always matches the installed version,
so instructions never go stale. The content in this stub cannot change
between releases, which is why it just points at `skills get core`.
## Specialized skills
Load a specialized skill when the task falls outside browser web pages:
```bash
agent-browser skills get electron # Electron desktop apps (VS Code, Slack, Discord, Figma, ...)
agent-browser skills get slack # Slack workspace automation
agent-browser skills get dogfood # Exploratory testing / QA / bug hunts
…
Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
