Agent Browser skill

The bundled agent-browser skill provides instructions for browser automation through the external agent-browser CLI.

Bundled with Selesai

Loaded automatically with Selesai; no per-extension npm install is required.

Manifest entry

./agent-browser.ts

Runtime surface

Skill-backed

Setup and prerequisites

• The skill is bundled with Selesai but the external CLI must be installed separately.
• Install it with npm i -g agent-browser && agent-browser install.
• The setup extension asks before running a global npm install when the CLI is missing.

What it sets up

• The agent-browser CLI and its browser runtime when the user accepts setup.
• A discovery skill that tells the agent to load workflows from agent-browser skills get core.

What you can configure

Agent-browser setup is prompt-driven: Selesai offers to install the external CLI when it is missing. The install flow can be skipped or re-run; there are no persistent settings.

No user configuration

This capability does not expose user-editable settings. Its behavior is controlled by the commands and runtime rules documented below.

Commands, tools, and shortcuts

Command	Description
npm i -g agent-browser	Install the external CLI globally.
agent-browser install	Provision the browser runtime.
/setup-agent-browser	Re-run Selesai’s setup flow.

Limits and safety

• Browser automation runs with the user’s local permissions and network access.
• Global npm installation can require user-specific permissions; Selesai asks for confirmation and reports failures without blocking the agent.
• The skill’s usage guide is served by the installed CLI, so workflow details follow the installed version.
