kortix-social

name: kortix-social 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.

1. 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.
2. Voice & messaging — read ../internal-comms/SKILL.md for tone, positioning, and canonical terminology before writing any copy. It governs what you say.
3. 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

Platform quick reference

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.

1. 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.

2. 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

3. Write standalone captions for each.

4. Spread across 1–2 weeks — never dump them all at once.

5. 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.
