About sctl

Drive the user's own running browser and ScriptCat from the terminal with the `sctl` CLI: list and organize tabs, windows, bookmarks, history, cookies, downloads and extensions; read and operate pages (accessibility snapshot, click, fill, screenshot, run JavaScript); inspect console errors and network requests; send raw CDP commands or hand a CDP endpoint to Playwright/Puppeteer; and view, search, install, edit, enable, run or delete ScriptCat userscripts and read their logs. Use this skill whenever the user wants something done or looked at in their real browser — "what tabs do I have open", "open this page and click…", "why is this page throwing errors", "which request is failing", "run my Playwright script against my logged-in browser" — or mentions sctl, sctl Browser or ScriptCat, even if they never name the tool. Not for ordinary front-end coding that does not touch the user's browser, and not for developing the sctl repository itself.
