Automations fill in and drive web pages through a small SDK on trusted input, with targets by label and every value read back. Your LLM agent writes them with the Tranquil Skill, and finer grants limit where and how a script acts.

Markdown Preview replaces the file in the same tab, PDFs render instead of showing as binary, CSV is syntax-highlighted, links in the terminal open as browser tabs, and browser tabs open and close where you expect.

A guide to why tab.evaluate can freeze the page it drives and how to avoid it, a worked example, and a performance pass over the panels that draw on top of the editor.

Deno runs each automation as a subprocess, with permissions declared per script. Adds a debugger: breakpoints, stepping, and variable inspection.

A refinement pass on the Dev Preview — history-ranked URL suggestions, per-site cookie clearing, richer User-Agent presets, and a batch of Studio fixes.
