Quickstart

Install the Codex Plugin

In Codex, open Plugins, choose Add plugin marketplace, and enter either agentrhq/webcmd or https://github.com/agentrhq/webcmd. Install Webcmd from that marketplace, then start a new task. On first use, the integration installs the npm CLI automatically if webcmd is missing. It includes exactly one bundled skill, webcmd-browser. Do not also add that skill with webcmd skills add in Codex.

Install the Claude Code Plugin

claude plugin marketplace add agentrhq/webcmd
claude plugin install webcmd@webcmd

This installs exactly one bundled skill, webcmd-browser. Do not also add that skill with webcmd skills add in Claude Code.

Other Agents or Plugin-Free Setup

Webcmd requires Node.js 20.6+ and an agent harness that can run shell commands.

npm install -g @agentrhq/webcmd
webcmd skills add

When prompted, choose Claude, Codex, another supported harness, or a custom skills path.

Ask Your Agent

Use Webcmd to find five companies currently hiring Forward Deployed Engineers.
Return company, role, location, a one-sentence description, and the source URL.
Research only: do not apply, contact anyone, or change my account.

What Happens Next

The agent creates a browser Session, inspects the live website, and returns the requested results. Webcmd retains useful, verified knowledge of the site’s structure so another agent can start faster next time. If the live page no longer matches that memory, the agent inspects the page again and updates its understanding.

Try Another Prompt

Use my logged-in `work` profile to collect open invoices from the Acme dashboard.
Return invoice_id, customer, due_date, amount, status, and detail_url. Pause if I
need to sign in, never ask me to paste credentials into chat, and do not change
any records.
