Agent Browser

Use the agent-browser CLI for deterministic browser automation through accessibility snapshots and ref-based interaction.

Refreshed against the pinned donor snapshot in EveryInc/compound-engineering-plugin; see references/source-parity.md for the exact source path and preserved behaviors.

Standards snapshot (March 2026)

• Prefer snapshot-driven refs over brittle selectors.
• Re-snapshot after navigation or meaningful DOM changes.
• Keep browser actions observable: every click, fill, or wait should have a verification point.
• Prefer command chaining or batch only when intermediate output does not need to be read before the next step.
• Use isolated sessions when parallel flows or risky state changes would interfere with each other.
• Turn on stricter safety controls when page content is untrusted or the action surface is risky.

When to use

• Interacting with live web pages or forms through the CLI.
• Capturing screenshots, PDFs, or structured snapshots.
• Scraping or validating page state with deterministic steps.
