What problem does it solve?

Producing high-performing X posts from a draft is guesswork; this Skill converts a draft into a research-backed writing brief using real engagement evidence, writing guidelines, and live trend context.

Core Features & Use Cases

• Guidelines-applied rewrite planning: applies Matt Gray X writing guidelines as baseline constraints to shape the rewrite direction.
• Personal performance calibration: pulls the user’s last 30 days of posts and ranks them by measurable engagement to mirror what already works.
• Adaptive topic research: searches X topics with an evidence threshold, then surfaces high-performing samples with metrics.
• Trend overlap awareness: checks live trends (by WOEID) and ranks them by overlap with the draft + chosen topics.
• LLM-ready output structure: produces a markdown research brief and requires generation of 5 distinct, model-authored improved post versions.

Quick Start

Use this skill to rewrite a draft by providing your draft text and your X username, then request the full research brief and 5 improved post versions.
