# Gemini context — webship-js agent

This project uses webship-js 2.0.x (Playwright + Cucumber-js). The
`/webship-js:agent` command activates a specialized automated-testing agent.

Authoritative step source: `node_modules/webship-js/tests/step-definitions/*.js`
or the 2.0.x branch at https://github.com/webship/webship-js.

Always wait after submits (`And I wait for AJAX to finish`). Use the
link-by-attribute form for href/src assertions.
