| description | Writes platform-native social content — LinkedIn posts, Twitter/X threads, carousels, Instagram/TikTok/Reels/Shorts video scripts, content calendars — and repurposes one long-form piece into many. Use when the user asks for a "LinkedIn post," "Twitter thread," "carousel," "social calendar," "what should I post," "repurpose this," "video hook," "reel," "short-form video," or to grow/strategize a social presence. |
Social Content
Turn product context into scroll-stopping, platform-native content — and turn one piece of content into many. This skill writes the words and the scripts; it hands visual production to kortix-image.
Before writing
Read the shared context first, then write — don't interrogate.
- Product context — read
/product-marketing.md. Reuse audience, personas, customer language, proof points, and goals from it. If it's missing, you can still work, but suggest setting it up via the product-marketing skill so every post stays on-product.
- Voice & messaging — read
../comms/SKILL.md for tone, positioning, and canonical terminology before writing any copy. It governs what you say.
- Visuals — for carousels, quote graphics, thumbnails, or video covers, don't describe pixels here — hand the brief to
../kortix-image/SKILL.md (which honors brand-guidelines).
Only ask for what the context doesn't cover: the goal (awareness / leads / traffic / community), platform(s), the action you want readers to take, and whether it's personal or company brand. Default sensibly from the context rather than asking.
Routing
| User intent | Mode |
|---|
| "write me a post / thread / carousel" | Create |
| "turn this blog/podcast/webinar into social" | Repurpose |
| "script a reel / TikTok / Short / video hook" | Video |
| "plan my week / build a calendar" | Plan |
| "what should I post? / I'm out of ideas" | Ideate |
Platform quick reference
| Platform | Best for | Cadence | Native format |
|---|
| LinkedIn | B2B, thought leadership | 3–5×/week | Text story, carousel, poll |
| Twitter/X | Tech, real-time, community | 3–10×/day | Thread, hot take, reply |
| Instagram | Visual, lifestyle | 1–2 + Stories daily | Reel, carousel |
| TikTok | Reach, younger audience | 1–4×/day | Short-form video |
Two distribution rules that apply almost everywhere: first-hour engagement decides reach, and external links in the post body suppress reach — put links in the first comment or a reply. Character/hashtag limits live in references/platform-limits.md.
Create
Every post is one hook + one idea + one action. The first line earns the second.
- Hook first. Pick a hook type to the goal — curiosity, story, value, or contrarian. Library in
references/post-templates.md. If reach is flat, the hook is almost always the cause; test new hooks before anything else.
- One idea per post. Don't pack a thread's worth of value into a single post — split it.
- Standalone. The reader has no prior context. A repurposed clip's caption must work even if they never saw the source.
- One clear action. A question, a save, a "link in comments" — never two.
- Match length and tone to the platform (limits file). LinkedIn rewards line breaks and 1,200–1,500 chars; X rewards brevity; carousels need a hook slide that promises a payoff.
Repurpose
The strongest social content isn't written from scratch — it's extracted from long-form and adapted per platform. This is the highest-leverage mode.
-
Mine content atoms — pull 5–10 self-contained moments from the source: a quotable claim, a complete mini-story, a tactical tip, a contrarian take, a data callout, a behind-the-scenes moment.
-
Adapt each atom to a format — same idea, native shape:
| Atom | Goes to |
|---|
| Quotable claim / hot take | X post, LinkedIn, quote graphic |
| Complete mini-story (setup→resolution) | Reel, TikTok, Short |
| Tactical tip / framework | LinkedIn carousel, Short |
| Data / stat | LinkedIn carousel, X |
| List of takeaways | X thread |
-
Write standalone captions for each.
-
Spread across 1–2 weeks — never dump them all at once.
-
Reshare evergreen atoms every 3–6 months.
Rough yield from one podcast/webinar/video: 3–5 short clips, 1–2 LinkedIn posts, 1 X thread, 1 carousel.
Video
Short-form video is the highest-reach format on every platform. Frameworks and the full hook library are in references/short-form-video.md. The essentials:
- 3-second rule — visual hook + verbal hook + text overlay, all landing in the first second. Show the payoff or the problem immediately; never build up to it.
- Pick a structure — Problem→Agitate→Solution→CTA, List (one item every 5–8s), or Tutorial (show the result first). Keep it 9:16, 15–60s.
- Caption everything — most short-form is watched on mute; subtitles lift watch time 25–40%. Max 2 lines, 3–5 words each, key word highlighted.
- Output a script with timestamped beats (hook / body / CTA) plus production notes (sound, b-roll, overlays). Hand any cover frame or thumbnail to
kortix-image.
Plan
Build around 3–5 content pillars the audience cares about and you can sustain — e.g. for a SaaS/dev-tool brand: industry insight (~30%), behind-the-scenes/build-in-public (~25%), educational how-tos (~25%), personal/opinion (~15%), promotional (~5%). Keep promo light.
Then produce a weekly grid (day × platform × pillar × format) and a batching plan: write the week's posts in one 2–3 hour block, schedule the evergreen ones, and leave gaps for real-time replies and trend-jacking. Maintain a 1–2 week queue, never more.
Ideate
When stuck, generate from the pillars, not from a blank page: repurpose a past high-performer, react to industry news, answer a real audience question, share a lesson or failure, or document what you're building this week. For each idea, name the pillar, the platform, and the hook before drafting.
