chrome-devtools-axi-browser-automation

What problem does it solve?

This Skill eliminates slow, brittle browser automation by giving agents a compact, consistent view of the page through accessibility tree snapshots and reliable element targeting.

Core Features & Use Cases

• Token-efficient accessibility snapshots that let agents reference elements using uid refs (uid=g<N>:<id>) for precise actions.
• Combined operations that reduce round-trips, such as navigating while capturing snapshot state and offering contextual next-step hints.
• Robust workflow support including staleness detection (STALE_REF prevention), screenshots, JS evaluation, and end-to-end flows for testing.
• Use Case: An agent can log into a web app, navigate to a feature page, submit a form, take a verification screenshot, and run Lighthouse to collect performance audit results—all while re-snapshotting safely when the DOM changes.

Quick Start

Tell your agent to run npx -y chrome-devtools-axi to get accessibility-tree-based Chrome automation tools it can use to navigate, snapshot, and interact with page elements by uid references.
