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).\n---\n\n# X Post Writer\n\nShip a single tweet, or a tight 2-3 tweet micro-thread, using hook shapes that\nactually travel on X in 2026. Single-tweet formulas land a complete punch in\nthe first line, because X has no \"see more\" fold.\n\n## When to use\n\n- User says \"write me a tweet about X\"\n- User has a topic or a rough one-liner and wants a sharper hook\n- User wants to pick a proven single-tweet shape and fill in their voice\n- User wants a quick draft that auto-publishes on approval\n\n## Formulas this skill uses (single-tweet shapes)\n\n| Code | Formula | Primary goal | Best for |\n|---|---|---|---|\n| X1 | One-Liner Contrarian | reposts | a sharp, defensible against-the-grain take |\n| X2 | Data-Point Hook | bookmarks | one odd-precision number that reframes a thing |\n| X3 | Build-in-Public Confession | replies | a real metric from your own work, ugly ones included |\n| X4 | Quote-Tweet Dunk-with-Value | reposts | adding a layer to someone else's take (quote tweet) |\n| X5 | Mini-List Tweet | bookmarks | a scannable list that fits in one tweet |\n| X6 | Relatable Cold-Open | likes | a specific shared moment, no setup |\n| X11 | Third-Person Case-Study Flex | reposts | someone else's absurd, specific result as anyone-could-copy bait |\n\nFull skeletons in `../../references/hook-formulas.md`. For long-form tweetstorms\n(X7-X10), use `x-thread-builder`. X11 was validated as the top-recurring winning\nshape in a ~450-tweet corpus (July 2026); prefer it over a first-person \"How I\"\nwhen the result you are citing is someone else's.\n\n### Pick by goal first\n\n| Goal | Reach for |\n|---|---|\n| Replies | X3, X1 |\n| Reposts | X1, X4, X11 |\n| Likes | X6 |\n| Bookmarks | X2, X5, X11 |\n\n## Steps\n\n**Voice profile first (all drafts).** If `../../references/voice-profile.md` has `filled: yes`, load it and match the user's voice fingerprint, hard rules, and CTA/link style throughout. If it is not filled, mention once that `x-humanizer --mode profile` can learn their voice from a few posts, then proceed with the generic voice rules.\n\n1. **Gather inputs.** Topic, angle, any rough draft, target audience (builders /\n   founders / a niche), and the goal (replies / reposts / likes / bookmarks).\n2. **Pick the container.** If the idea is one claim, one number, or one moment,\n   it is a single tweet. If it is a scannable one-line-per-item list, still a\n   single tweet (X5). If items need teaching or the idea has a build, hand off\n   to `x-thread-builder`.\n3. **Pick the formula.** Use the goal table to shortlist, then suggest 2-3 that\n   also fit the topic and let the user choose.\n4. **Draft the tweet.** Fill the skeleton in the user's voice. Respect the 2026\n   X rules:\n   - First line carries the whole load (no fold).\n   - Under 280 chars on a standard account (emoji count as 2 chars). Confirm the\n     user's tier; only go long if they are on Premium and the length earns it.\n   - One idea per tweet. Line breaks as beats.\n   - 0-1 hashtag at the end, 0-1 emoji, none on a serious take.\n   - No external link in the tweet (offer to put it in a reply).\n5. **Humanizer pass.** Scrub 2026 AI vocab by density, cap em dashes (at\n   most one per tweet, never swap one for a period), break stacked triads,\n   generic openers and reveal bridges. Leave a single tweet's rhythm alone\n   (uniform rhythm wins on short posts; never insert a fragment for punch).\n   Add an odd-precision number with a named referent or a named entity where\n   the claim allows it. Canonical rules: `x-humanizer` V3.\n6. **Optional audit.** Invoke `x-humanizer --mode audit` for a pass-fail check.\n7. **Approval card.** Show: formula used, full draft, char count (note if emoji\n   push it over 280), suggested posting window, primary goal.\n8. **On approval.** Call `lib.publish(kind=\"post\", draft_text=<approved>,\n   target_url=\"https://x.com/compose/tweet\", platforms=[<X_PLATFORM_ID>],\n   scheduled_time=<iso_or_None>)`. The wrapper handles Publora / manual / diy\n   routing. If the content runs long, Publora auto-splits it into a numbered\n   thread.\n\n## Hard rules\n\nGlobal voice rules: see root `SKILL.md` Voice rules. Additional skill-specific\nrules:\n\n- The first line must stop the scroll on its own. Rewrite any opener that needs\n  line 2 to make sense.\n- Keep a standard-account tweet inside 280 chars. If it does not fit, tighten it\n  or escalate to a thread, never ship a truncated thought.\n- One specific number where the claim allows it. 2.4x beats \"way better\".\n- Do not hard-sell the user's product. One natural mention max.\n\n## Anti-patterns (skill will refuse)\n\n- ALL CAPS first line for intensity. Carry intensity with word choice.\n- Em dashes above the cap (more than one in a tweet), or an em dash swapped for a period.\n- \"Here's what / here's how\" or \"Stop X, start Y\" as the opener; \"The result?\" as a reveal.\n- Announced candor (\"Let me be honest\", \"not gonna lie\") with no dated fact behind it.\n- \"Unpopular opinion:\" on a take that is actually popular.\n- Padding a one-line idea with filler to look substantial.\n- Rule-of-three lists without specifics.\n- \"leverage\", \"fundamentally\", \"game-changer\", \"deep dive\".\n- External link in the tweet body.\n- Engagement bait (\"RT if you agree\", \"reply YES\").\n\n## Resources\n\n- `../../references/hook-formulas.md` - all 11 X formula skeletons (X1-X6 and X11 are single-tweet)\n- `../../references/algorithm-heuristics.md` - 2026 X ranking rules (signals, timing, limits)\n- `references/single-tweet-checklist.md` - the per-tweet scrub and fit list\n\n## Optional illustration\n\nOffer a generated image when a visual would lift reach. Draft a prompt and call\n`lib.illustrate(prompt, kind=\"wide\")`, pulling brand handle/color from Voice &\nBrand Profile section 6 for a pixel-exact overlay. Show the returned `url` + `cost`,\nthen attach on publish via `media_urls=[url]`. Full workflow (incl. quote-cards):\n`../x-humanizer/sub-skills/illustration.md`. No Pixfaro key -> it drafts the prompt for you to generate manually.\n## Related skills\n\n- `x-thread-builder` - when the idea needs more than a tweet\n- `x-humanizer` - aggressive AI-tell scrubber, plus `--mode audit` for review\n- `x-hook-extractor` - reverse-engineer a hook from a tweet you admire\n","tagline":"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).
