Re-expresses one finished piece of content as the native-equivalent post on each target channel, holding the core idea constant while flexing length, structure, register, and conventions per platform. Use when you have a single written post, article, script, or message and need the same idea posted natively on LinkedIn, X, Instagram, TikTok, YouTube Shorts, or a newsletter. Do NOT use when fanning one long-form asset out into different asset types (clip, quote card, blog) - use content-repurposing instead; do NOT use when writing one fresh caption from a topic - use social-caption-writer instead.This is the skill's description: the text your AI reads to decide when the skill applies.

# Cross-Platform Reformatter
Take one existing piece and ship the same idea as a native post on each requested channel - not the same text with hashtags swapped.
## Workflow
1. Extract the core: pull the single transferable idea plus its proof (the stat, story, or takeaway). This stays constant across every version; everything else is rebuilt around it.
2. Confirm the target channels. Reformat only the channels the user named; do not invent a full distribution stack. If they named none, ask which channels.
3. Rebuild - do not truncate - for each target, in its native grammar:
- LinkedIn: text-first, ~1300-2000 chars, short lines with white space, professional-but-human, one clear insight.
- X: a tight single post under 280, or a thread where each post stands alone; punchy, no corporate tone.
- Instagram: caption ~125-150 chars or a short narrative; the image/Reel carries the weight.
- TikTok: a spoken script with a verbal hook in the first two seconds; conversational, written to be said aloud.
- YouTube Shorts / Reels: the same script logic with on-screen text beats.
- Newsletter: longest form; keep the nuance the social cuts drop.
4. Apply native conventions per channel: hashtags 3-5 on Instagram, 1-2 on LinkedIn/X, a couple of discovery tags at most on TikTok; use features as intended (carousels/Reels on IG, document posts and polls on LinkedIn, threads and quote-posts on X); tune emoji density to the channel.
5. Hold voice, shift register: keep signature phrasing so the brand stays recognizable; go more formal on LinkedIn, looser on TikTok and X; drop jargon that does not travel to a casual feed.
6. If output feeds a calendar, note sequencing: long-form first (the anchor), then the atomized versions pointing back to it, staggered over days rather than dumped at once.
7. Label each version with its target channel and format on delivery.
