Skills
Snapshot And Refs
Captures the page accessibility tree with element refs, then clicks, fills, and reads elements by ref or by locators such as role and label.
Agent-Friendly Reading
Reads a URL as markdown without launching Chrome, or the active tab's rendered DOM, with outline, filter, llms.txt, and JSON output options.
Snapshot And Visual Diff
Compares accessibility snapshots or screenshots against a saved baseline, or two URLs against each other, to show what changed on a page.
MCP Tool Profiles
Starts a stdio MCP server whose tool profiles, such as core, network, and react, keep the tool list small or expose full CLI parity.
Login State Persistence
Reuses Chrome profiles, saved state files, restored sessions, or an encrypted local credential vault so agents skip logging in on every run.
