| description | Use when creating, reviewing, or improving X posts with guidance grounded in the public X For You algorithm release, or when working with the X For You feed stack including Home Mixer, Phoenix retrieval/ranking, Thunder, Grox content understanding, ads, filters, hydrators, scorers, and recommendation-system inference artifacts. |
X Algorithm
How To Use This Skill
This skill is self-contained. Use the bundled references when the original X algorithm repository is not installed.
For post creation or review, load references/post-strategy.md first. Treat it as evidence-grounded guidance, not a promise of reach. Default to direct, specific, ready-to-post writing that matches the user's requested voice. Do not claim exact production weights, private ranking rules, or guaranteed distribution.
For engineering work, use the architecture references to understand, explain, or modify the X For You recommendation stack: Home Mixer orchestration, Phoenix retrieval/ranking, Thunder in-network serving, Grox content-understanding tasks, candidate pipelines, ads, filters, hydrators, scorers, selectors, or side effects.

Working Rules For Posts
- Optimize for predicted user value: likely replies, reposts, clicks, dwell, shares, follows, and low negative feedback.
- Preserve eligibility: avoid spam patterns, bait, misleading framing, unsafe content, muted-keyword triggers, duplicate posts, and low-quality replies.
- Build posts around a clear audience and topic so retrieval, embeddings, and user-history matching have strong signals.
- Prefer specific, self-contained posts over vague engagement prompts.
- When reviewing a draft, return concrete edits and a short rationale tied to the bundled algorithm references.
- For drafting, return the ready-to-post copy first, then optional notes only when useful.
If The Repo Is Present
If the workspace also contains the repo, use rg first and then inspect the narrowest file set for the requested task.
