X / Twitter Automation

X uses Draft.js (the original Facebook rich-text editor) for the compose text area, which was the original canary for all the rich-text editor quirks the browser-automation skill now documents. Most of the site is otherwise stable, data-testid attributes have held up for years, the SPA is reasonably honest about what it renders, and shadow DOM is minimal. The hard parts are the composer, rate limiting, and the occasional anti-bot challenge.

Always activate browser-automation first. This skill assumes you already know about CSS-px coordinates, click-first typing, and Input.insertText. The guidance below is X-specific.

Timing expectations

• browser_navigate(wait_until="load") returns in 1.3, 1.6 s on a warm cache.
• After navigation, sleep(2, 3) for SPA hydration before querying selectors.
• Compose modal slide-in: ~1.5 s after clicking reply / compose.
• First 1, 2 characters typed into the compose editor may be dropped, see "Draft.js quirks" below.
