x-post-writer

description

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).

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

Full skeletons in ../../references/hook-formulas.md. For long-form tweetstorms (X7-X10), use x-thread-builder.

Pick by goal first

Goal	Reach for
Replies	X3, X1
Reposts	X1, X4
Likes	X6
Bookmarks	X2, X5

Steps

1. Gather inputs. Topic, angle, any rough draft, target audience (builders / founders / a niche), and the goal (replies / reposts / likes / bookmarks).
2. Pick the container. If the idea is one claim, one number, or one moment, it is a single tweet. If it is a scannable one-line-per-item list, still a single tweet (X5). If items need teaching or the idea has a build, hand off to x-thread-builder.
3. Pick the formula. Use the goal table to shortlist, then suggest 2-3 that also fit the topic and let the user choose.
4. Draft the tweet. Fill the skeleton in the user's voice. Respect the 2026 X rules:
   • First line carries the whole load (no fold).
   • Under 280 chars on a standard account (emoji count as 2 chars). Confirm the user's tier; only go long if they are on Premium and the length earns it.
   • One idea per tweet. Line breaks as beats.
   • 0-1 hashtag at the end, 0-1 emoji, none on a serious take.
   • No external link in the tweet (offer to put it in a reply).
5. Humanizer pass. Strip em dashes, AI vocab, rule-of-three, generic openers. Add a specific number or named entity where the claim allows it.
6. Optional audit. Invoke x-humanizer --mode audit for a pass-fail check.
7. Approval card. Show: formula used, full draft, char count (note if emoji push it over 280), suggested posting window, primary goal.
8. On approval. Call lib.publish(kind="post", draft_text=<approved>, target_url="https://x.com/compose/tweet", platforms=[<X_PLATFORM_ID>], scheduled_time=<iso_or_None>). The wrapper handles Publora / manual / diy routing. If the content runs long, Publora auto-splits it into a numbered thread.

Hard rules

Global voice rules: see root SKILL.md Voice rules. Additional skill-specific rules:

• The first line must stop the scroll on its own. Rewrite any opener that needs line 2 to make sense.
• Keep a standard-account tweet inside 280 chars. If it does not fit, tighten it or escalate to a thread, never ship a truncated thought.
• One specific number where the claim allows it. 2.4x beats "way better".
• Do not hard-sell the user's product. One natural mention max.

Anti-patterns (skill will refuse)

• ALL CAPS first line for intensity. Carry intensity with word choice.
• Em dashes anywhere.
• "Unpopular opinion:" on a take that is actually popular.
• Padding a one-line idea with filler to look substantial.
• Rule-of-three lists without specifics.
• "leverage", "fundamentally", "game-changer", "deep dive".
• External link in the tweet body.
• Engagement bait ("RT if you agree", "reply YES").
