Try useful browser work where the result is easy to see and nothing important is at risk. These pages cover reading, forms, pointer work, browser signals, and local artifacts. Nothing here submits elsewhere, calls out elsewhere, or remembers anything.
Runs a guided capability tour end to end against these pages, with room to see each step land. Or drive any single scenario yourself from your own MCP client.
Read a calm dark workspace, fill a compact form, choose two useful constraints, and finish on a clear local success state.
ghostlight demo-brief / read_page / form_fill / computer Guided story - Card FoundryInspect a holographic TCG card, reject a print defect, review its revision, assemble evidence, and stop at the governed production boundary.
gif_creator / screenshot / zoom / drag / form_fill / governance 01 · DeskA button, a field, a drag lane, a scroll region, and a dialog. The agent clicks, types, drags, scrolls, and answers the page while the sky-blue cursor and ripples trace every move.
computer · find · read_page 02 · FormA plain contact form. The agent completes every field and submits - and the page confirms receipt without sending a single byte anywhere.
form_fill · form_input 03 · SignalsButtons that log to the console, fetch a small JSON file, and finish a slow task. The agent reads the console, the network, and waits for the result.
read_console_messages · read_network_requests · wait_for 04 · Reading roomA page of real prose and structure. The agent extracts the text, maps the accessibility tree, and finds a specific passage on request.
get_page_text · read_page · find 05 · Capture StudioA local workbench for handing a screenshot back to the page, opening a harmless file, and replaying the tour as an animated capture.
upload_image · file_upload · gif_creator 06 · Embedded formA partner-application form that lives in an embedded frame, like every hosted form vendors rent out. The agent inspects it, fills it, and submits it as if it were one document.
read_page · find · form_fill · wait_for 07 · Shadow componentsA web-component form whose fields live inside a shadow tree, read and filled like ordinary markup - beside a sealed closed-root widget that stays honestly invisible.
