Want your agent to post to X for you? That is Liftli's Business plan: [see pricing](https://liftli.ai/pricing), or [start free](https://app.liftli.ai/console/login?intent=signup) (no card) to try the strategist first. Useful? [Star it on GitHub](https://github.com/liftli-ai/x-agent-skills) so others find it. Maintained by [Oded Tsamir](https://www.linkedin.com/in/odedtsamir/), founder of Liftli · last reviewed October 2026 ## What these are A skill is an installable instruction package: a `SKILL.md` your agent reads and runs with its own model. Each of these teaches your agent one X job done well: a post that makes sense cold on a phone, a thread where post 1 works alone, a reply worth answering, a bio a stranger understands in one read. New here? Ask your agent *"help me with my X"*. The `x-agent` skill picks the right skill, and `x-voice` builds a voice file from your own posts and replies so drafts sound like you. It is the same file the [LinkedIn agent skills](https://liftli.ai/skills/) read, so you build it once. The skills write and check; they never post. `x-publish` hands you a copy-ready post, or publishes through Liftli after you approve. Install everything with the command above, or a single skill with `--skill `. Every card below carries its exact command. **Skills are the craft. The Liftli MCP is the engine.** Voice learned from your real posts, material mined from your week, strategy memory, and publishing to X and LinkedIn behind your one-tap approval, inside the same agent. Free to start, no card.

Each point is tagged as backed by X's open-sourced ranking code (replies, quotes, shares, follows; mutes, blocks, reports) or as craft. Lists the popular algorithm claims that have no source. `npx skills add liftli-ai/x-agent-skills --skill x-algorithm-check` [Source (SKILL.md)](https://github.com/liftli-ai/x-agent-skills/tree/main/skills/x-algorithm-check) ## Profile Bio, name, pinned post Profile ### `x-bio-generator` X Bio Generator Five bios within X's 160-character limit that tell a stranger who the user helps and why to follow, plus a name, a pinned-post idea and header text. `npx skills add liftli-ai/x-agent-skills --skill x-bio-generator` [Source (SKILL.md)](https://github.com/liftli-ai/x-agent-skills/tree/main/skills/x-bio-generator) ## Why the X skills start with replies X ranks the For You feed by predicting what each reader will do with a post and adding up weighted predictions. The skills follow what X has published, not folklore: - **Conversation outweighs approval.** In the ranking code X released in 2026, a predicted reply or quote is weighted 5.0, a like 0.6 ([xai-org/x-algorithm](https://github.com/xai-org/x-algorithm/blob/main/home-mixer/params/param.rs)). The 2023 release weighted a reply 13.5 and a reply the author engages with 75 ([the-algorithm-ml](https://github.com/twitter/the-algorithm-ml/blob/main/projects/home/recap/README.md)). - **Bad posts cost.** Mute author is weighted -58.8, not interested -47.52, block -31.2 and report -234. Bait and rage hooks risk exactly those. - **Read the weights honestly.** X notes that they scale predicted probabilities, not raw counts. They show direction, never a "one reply equals N likes" sum. - **A human posts every reply.** X's [automation rules](https://help.x.com/en/rules-and-policies/x-automation) forbid automated replies based on keyword searches, and AI reply bots need X's prior written approval. So the skills draft and you post. `x-algorithm-check` carries the full weight table, the date it was checked, and the popular claims (such as "links cut reach 50%") that the published code does not support. ## Skills vs. the full pipeline Skills are stateless: your agent brings the model, the skill brings the craft. What they can't know is *you*: your voice, your strategy, what you shipped this week, what worked last month. That is the [Liftli strategist for X](https://liftli.ai/x). It connects to the same agent as an [X MCP server](https://liftli.ai/x-mcp), learns your voice from your real posts, keeps your strategy between chats, and publishes or schedules posts and threads through X's official API after you approve each one. X publishing is on the Business plan, with a fair-use cap of 100 posts a month. Connector details for agents: [liftli.ai/llms.txt](https://liftli.ai/llms.txt). ## X agent skills on GitHub, compared A few public X skill collections exist on GitHub, and they do different jobs.

The agent's own model runs it, so there is no X API key and nothing to connect. This page lists 11 of them, free and MIT-licensed. **How do I use Claude for X (Twitter)?** Install these skills into Claude Code with npx skills add liftli-ai/x-agent-skills, or as a plugin with /plugin marketplace add liftli-ai/x-agent-skills and then /plugin install x-agent-skills@liftli-x. Then ask your agent for help with your X. The x-agent skill routes the request, and x-voice builds a voice file so drafts sound like you. To let Claude publish to X, connect Liftli, which posts through X's official API after you approve. **Can Claude Code post to X?** Not with skills alone, and it should not script the X website: X's automation rules forbid non-API automation and say it can lead to permanent suspension. Posting needs an app connected to your account through X's official API. The x-publish skill gives you a copy-ready post or thread, or connects Liftli, which publishes and schedules through the official API after you approve each post. X publishing is on Liftli's Business plan. **Why do these skills focus on replies?** Because X's own ranking code does. In the For You algorithm X published in 2026, a predicted reply or quote is weighted 5.0 against 0.6 for a like, and mutes, blocks, reports and not-interested clicks carry large negative weights. X notes that the weights scale predicted probabilities, not raw counts, so they show direction, not arithmetic. The x-reply-generator skill drafts short, specific replies that you post yourself. **Do I need an X API key or a developer account?** No. The skills are markdown files that your agent's model reads, and they never call X. You post the result yourself, or connect Liftli, which handles X's official API for you. **Do these work with the LinkedIn agent skills?** Yes. Both sets read the same voice file, .liftli/voice.md, so you build it once; the X set adds a section for how you sound on X. linkedin-to-x and x-to-linkedin move a post between the two networks. The 31 LinkedIn skills are at liftli.ai/skills. **Which AI agents support these skills?** Any client that reads the open SKILL.md format, such as Claude Code, Codex and Cursor. Install with npx skills add liftli-ai/x-agent-skills. The skills are plain markdown, so an agent without a skills manager can read them straight from the GitHub repository. **Are the skills really free?** Yes. They are MIT-licensed and run on your agent's own model, so Liftli sees nothing and meters nothing. They are the single-job versions of what Liftli does as a full pipeline: voice learned from your real posts, strategy memory, and publishing to X and LinkedIn behind your approval.
