Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Platforms: X (Twitter)

Guides X post copy creation and optimization. Use for generating publish-ready posts, threads, and content that performs on X. Suitable for copy agents, design agents (image specs), and video agents (video post specs).

**When invoking**: On **first use**, if helpful, open with 1-2 sentences on what this skill covers and why it matters, then provide the main output. On **subsequent use** or when the user asks to skip, go directly to the main output.

## Output: Publish-Ready Copy

This skill enables agents to generate X post copy that can be published directly. Output includes character-counted text, thread structure, and platform-compliant formatting.

## Character Limits

| Type | Limit | Notes |
|------|-------|-------|
| **Standard post** | 280 characters | Most users |
| **Premium** | 25,000 characters | X Premium subscribers |
| **URL** | Counts as 23 chars | t.co shortens all links |
| **Emoji** | ~2 chars each | Varies by emoji |

## Optimal Lengths (Engagement)

| Use Case | Characters | Purpose |
|----------|------------|---------|
| **General** | 71-100 | Sweet spot for engagement |
| **Promotional** | 120-130 | Product/offer posts |

How to install

The exact contents, by fingerprint

mdr add kostja94/marketing-skills/twitter-x-posts@sha256:31b432ec3dc687d8

The line at the top of this page pins the label v1.1.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
