Gull runtime usage guide for browser automation sandboxes. Covers the agent-browser CLI passthrough model, snapshot-based element referencing, single vs batch execution strategies, artifact handling, and browser state persistence. Use this when working inside a Gull container to understand command syntax, critical rules for reliable automation, and common patterns for navigation, form filling, data extraction, and screenshot capture.
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
# Gull Runtime: Browser Automation Gull is a containerized browser automation runtime that wraps the `agent-browser` CLI with automatic session isolation and browser state persistence. It exposes a thin HTTP API (`/exec`, `/exec_batch`) for executing browser commands. ## Container Base Image - **Base**: `python:3.11-slim-bookworm` with uv package manager - **Browser Engine**: Chromium (via Playwright) - **CLI**: `agent-browser` (globally installed via npm) - **Node.js**: v20 LTS - **Workspace**: `/workspace` (shared Cargo Volume with Ship container) ## Architecture ``` ┌──────────────────────────────────────┐ │ Gull Container │ │ │ │ ┌──────────────────────────────┐ │ │ │ FastAPI Wrapper │ │ │ │ POST /exec │ │ │ │ POST /exec_batch │ │ │ └──────────┬───────────────────┘ │ │ │ subprocess │ │ ┌──────────┴───────────────────┐ │ │ │ agent-browser CLI │ │ │ │ + Playwright Chromium │ │ │ └──────────┬───────────────────┘ │ │ │ │ …

How to install
mdr add astrbotdevs/shipyard-neo/browser-automation@sha256:71d259b485a007c1The line at the top of this page pins the label git:20260211.5c1684d, 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.
