Author and operate Selenium Grid 4 - self-hosted distributed WebDriver. Covers the six-component architecture (Router / Distributor / Session Map / Event Bus / New Session Queue / Node), standalone vs hub-and-node modes, the Docker-image stack (selenium/standalone-chrome, selenium/hub, selenium/node-chrome), node registration, session-queue tuning, and observability. Use for self-hosted cross-browser testing when data residency or cost-control require an on-prem grid. This is the self-hosted execution RUNNER - for the zero-infra alternative use browser-matrix-runner (Playwright bundled engines); for managed cloud grids use browserstack-automate, saucelabs-automate, or lambdatest-automate; to decide WHICH browsers and tiers to run use browser-matrix-strategy-reference.

1 low severity finding. Worth noting, but not necessarily harmful.
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
The required runtime workflow is Selenium Grid 4’s HTTP/WebDriver execution path (Router at `/wd/hub`, plus `/graphql` and `/status`) which necessarily ingests outsider-authored free text from WebDriver clients (e.g., requested capabilities/session parameters) and returns responses.
