Turn product context into platform-native content, and turn one piece of content into many. This skill writes the posts and the scripts. It hands visual production to kortix-image.
Load kortix-brand first. It owns voice, positioning, claims and the words not to say. This file owns platform mechanics only.
Before writing
Read the kit, then write. Do not interrogate.
- Voice and vocabulary.
voice-and-tone.md, section 5.9 (Social), and the don't-say list. - Positioning and audience.
positioning.md: the approved lines and the pitch for the audience. - Claims.
claims.md. A post makes only a sanctioned claim. Never name a customer. - Visuals. For carousels, quote graphics, thumbnails or video covers, hand the brief to
kortix-image. Do not describe pixels here.
Ask only for what the kit does not cover: the goal (awareness, leads, traffic, community), the platform, the action you want from readers, and whether the voice is personal or company. Default from the kit.
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 |
|---|---|---|---|
| B2B, thought leadership | 3–5×/week | Text story, carousel, poll | |
| Twitter/X | Tech, real-time, community | 3–10×/day | Thread, hot take, reply |
| 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. A hook states a mechanism or a fact. It does not use a banned hype word, and "contrarian" never means an attack on a named product. 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.
