How to use the X/Twitter Growth Mentor agent skill (x-mastery-mentor)

What the skill makes the agent do

The agent first asks what kind of post or account goal you have, then follows a set workflow. It can suggest hooks and post structures, check drafts against a quality checklist, plan growth steps for your follower stage, and, if you allow it, review your account's recent posts and write a diagnostic report.

The skill says it cannot write for you, guarantee growth speed, or predict future algorithm changes. Its advice draws on bundled references about creator methods and platform mechanics, and it states that its algorithm data is dated to April 2026.

• Tweet and thread writing: hook options, 1/3/1 rhythm, four-part thread structure
• Topic ideas when you feel stuck
• Reviewing a draft you already wrote, with a diagnostic score
• Growth plans by follower stage (0-1K, 1K-10K, 10K-100K)
• Account diagnosis from your own posts, saved in a local user-data folder

Install the skill (ZIP download or Claude apps)

Download the ZIP from this page and unzip it. For a personal install, place the folder in ~/.claude/skills/. For a single project, place it in that project's .claude/skills/ folder.

You can also upload the skill in the Claude apps under Settings → Capabilities → Skills.

• Personal: ~/.claude/skills/
• Per project: .claude/skills/ inside your project
• Claude apps: Settings → Capabilities → Skills, then upload

Trigger the skill with natural requests

You do not need a special command. The skill's description lists trigger phrases, so ordinary requests activate it. Examples from its description include asking how to write a tweet, asking for help thinking of X content, asking about growing on X, and asking to write a tweet or grow on X in English.

Be specific about the post type and audience. The skill's defaults, when you don't say, are a short tweet, Chinese, aimed at AI and tech practitioners.

• 这条推文怎么写 (how should I write this tweet)
• 帮我想个X内容 (help me think of X content)
• 怎么涨粉 (how do I grow followers)
• Write a tweet about my product launch
• Grow on X: I have about 800 followers

Examples of what to ask

For writing, paste a draft and ask for a review. The skill runs its checks and returns a score with the main problems. For strategy, state your follower count and whether you have Premium, because the skill asks for these before giving growth advice.

For account review, provide your handle. The skill tries browser tools first, then a Chrome extension route, then asks you to supply exported data.

• Review: paste a draft and ask whether the hook works
• Plan: ask for this week's posting and growth actions for your stage
• Diagnose: give your @username and ask for a report from your last posts

What you need

The skill runs on Claude or another SKILL.md-compatible agent. The account diagnosis flow needs either browser tools (computer-use or a Chrome extension) or manually exported post data in CSV, JSON or pasted text. A local user-data folder is optional; if present, the skill saves your profile, post exports, reports and strategy notes there.

• For diagnosis: browser tools or exported post data (CSV, JSON or pasted text)
• Optional: a local user-data folder

Safety notes: scripts and network

The skill does not run scripts. It does use the network: the diagnosis flow can open your X profile page through browser automation. That collection may conflict with platform terms, so use it with judgement. Only analyse accounts you have a right to review, and prefer your own exported data.

The skill also notes that it focuses on X and will say so if you ask about other platforms such as Douyin or Xiaohongshu.

• No scripts are run by this skill
• Network use: yes, mainly for account diagnosis
• Browser scraping of others' accounts may breach platform terms
• Treat its performance claims as unverified until you test them
