Write viral X posts using deep knowledge of the actual recommendation algorithm

Package Exports

    This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (x-algorithm-skill) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

    X Algorithm Skill

    Write viral X posts using deep knowledge of the actual recommendation algorithm.

    This skill gives Claude Code (and other AI tools) detailed knowledge of how X's "For You" feed algorithm works, enabling it to help you write posts optimized for maximum reach.

    Installation

    npx x-algorithm-skill init

    Or install globally:

    npm install -g x-algorithm-skill
x-algorithm-skill init

    Usage

    After installation, use the skill in Claude Code:

    What's Inside

    The skill teaches Claude about:

    • Scoring Signals: The 19 engagement signals the algorithm predicts (replies, shares, dwell time, etc.) and their relative weights
    • Retrieval & Discovery: How the two-tower neural network finds relevant posts for users
    • Content Structure: Optimal formatting for dwell time and engagement
    • Viral Patterns: 8 proven templates that trigger high-value signals
    • Anti-Patterns: What gets penalized (engagement bait, rage bait, over-posting)
    • Iteration Framework: A systematic checklist for improving drafts

    How It Works

    X's "For You" feed is powered by:

    1. Phoenix Retrieval: Two-tower neural network that matches post embeddings to user interest embeddings
    2. Phoenix Ranking: Grok transformer that predicts 19 engagement probabilities
    3. Weighted Scoring: Probabilities × weights = final score
    4. Penalties: Out-of-network penalty, author diversity decay, age filtering

    This skill encodes all of this into actionable guidance.

    The Key Insight

    The algorithm doesn't care about "engagement" generically. It cares about specific actions:

    • High-value: Replies, DM shares, copy-link shares, dwell time, follows
    • Medium-value: Likes, retweets, profile clicks
    • Negative: Not interested, mute, block, report

    A post with 50 likes and 20 replies scores better than one with 100 likes and 0 replies.
