Twitter X Posts

Generates publish-ready X (Twitter) post copy with proper character counts, thread structure, and platform formatting baked in. Handles standard 280-character posts and Premium's 25,000-character limit, accounts for URL shortening (23 chars via t.co), and formats emoji correctly. Built for copy agents to output text you can paste directly into the composer, but also gives image and video agents the specs they need for visual posts. The character limit enforcement is the real value here since going over kills engagement and wastes the draft. Part of kostja94's marketing-skills collection alongside LinkedIn, TikTok, and Meta tooling.
