Draft a single tweet or short auto-thread for X (Twitter) using a 2026 X hook formula (one-liner contrarian, data-point, build-in-public, mini-list, relatable cold-open), picked by goal (replies, reposts, likes, bookmarks). Respects the 280-char limit (25,000 on Premium), runs the humanizer pass, and publishes via Publora on approval. Use to write a tweet from notes. Not for long threads (use x-thread-builder) or auditing a draft (use x-humanizer --mode audit).
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
# X Post Writer Ship a single tweet, or a tight 2-3 tweet micro-thread, using hook shapes that actually travel on X in 2026. Single-tweet formulas land a complete punch in the first line, because X has no "see more" fold. ## When to use - User says "write me a tweet about X" - User has a topic or a rough one-liner and wants a sharper hook - User wants to pick a proven single-tweet shape and fill in their voice - User wants a quick draft that auto-publishes on approval ## Formulas this skill uses (single-tweet shapes) | Code | Formula | Primary goal | Best for | |---|---|---|---| | X1 | One-Liner Contrarian | reposts | a sharp, defensible against-the-grain take | | X2 | Data-Point Hook | bookmarks | one odd-precision number that reframes a thing | | X3 | Build-in-Public Confession | replies | a real metric from your own work, ugly ones included | | X4 | Quote-Tweet Dunk-with-Value | reposts | adding a layer to someone else's take (quote tweet) | | X5 | Mini-List Tweet | bookmarks | a scannable list that fits in one tweet | | X6 | Relatable Cold-Open | likes | a specific shared moment, no setup | …

How to install
mdr add sergebulaev/x-skills/x-post-writer@sha256:0be6f448eebe345eThe line at the top of this page pins the label git:20261003.c4ac9ba, 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.
