X Thread Poster

Overview

Use Chrome DevTools MCP to compose and publish X threads from the user's active browser profile. Treat posting as a live external action: publish only when the user explicitly asks to post; otherwise stop after drafting or previewing.

Workflow

1. Load Chrome DevTools MCP tools if they are not already available.
2. Prepare the complete thread text before touching the composer.
3. Open https://x.com/compose/post or https://x.com/home.
4. Use wait_for and take_snapshot to confirm the logged-in composer is visible.
5. Enter each post with real browser input events, not DOM-only filling.
6. Add another post for each thread item.
7. Click the final publish button only after all posts are present and under limits.
8. Confirm publication from the timeline or returned status links.
