X Writing Skill

Overview

Transform your notes, work updates, and observations into engaging X (Twitter) content. This skill analyzes your notes to identify the most shareable insights, then crafts authentic posts that match your voice and drive engagement.

Supports two idea sources — a markdown file (X_SOURCE_FILE) and/or macOS Notes (X_NOTES_APP_SOURCE). If both are configured, asks which to use.

Process

Phase 1: Preparation and Analysis

1.1 Load Writing Guides (REQUIRED - Load First)

Before any other work, load the following:

1. Growth Principles (references/x-strategy.md) - Content selection criteria, what makes posts shareable, engagement patterns, and what to prioritize from notes. This guides WHAT to share.

2. Writing Style Guide (from WRITING_STYLE_GUIDE_PATH env var) - Voice, tone, structure, banned phrases, and signature patterns. This guides HOW to share it. Skip if the env var is not set.
