Analyze A/B tests across hook variations, posting times, content formats, and CTAs — declare statistical winners, document learnings, and build an always-on optimization engine.
Track post-level metrics across all platforms — impressions, engagement rate, profile clicks, follows, link clicks — with weekly aggregation and trend detection for performance analysis.
Generate weekly and monthly performance summary reports — top/bottom posts, content type analysis, pillar performance, follower growth, conversion tracking, and actionable recommendations.
Write Instagram and LinkedIn captions with scroll-stopping hooks, value-dense bodies, platform-appropriate CTAs, and strategic hashtag sets — optimized for each platform's reading behavior and visual context.
Select and write the optimal call-to-action for any social post — follow, reply, DM, save, share, link, or signup — matched to platform, content type, content value, and audience psychology.
Generate 5-10 hook variations for any post, thread, or caption across X, LinkedIn, Instagram, and TikTok — using different styles (question, contrarian, statistic, story, observation, promise) so the best one can be tested or selected.

Write a single platform-native post that earns attention, delivers value, and drives action. Each platform demands different structure, length, and energy. A post written for X does not belong on LinkedIn, and vice versa. This skill produces posts that feel native, not cross-posted.
The single biggest mistake brands make is writing one post and copying it to every platform. That doesn't save time — it wastes reach. This skill writes for the platform first, preserving the core message but expressing it in the format the audience expects to see there.
hook-write)| Platform | Char Limit | Hook Style | Link Rules | Hashtag Rules | Best Format |
|---|---|---|---|---|---|
| X | 280 (premium: 25K) | First 3 words are everything | Avoid in first tweet; use reply or final tweet | 0-1 per post | Short takes, hot takes, observations |
| 3,000 (ideal: 900-1,200) | First 2 lines before "see more" | Anywhere, ideally after hook | 3-5 at end | Stories, lessons, frameworks | |
| 2,200 (ideal: 125-150) | Visual + first line of caption | Bio link only (no clickable links in caption) | 5-10 relevant + 2-3 branded | Visual-led, micro-blogging in captions | |
| TikTok | 4,000 caption (video leads) | First 1.5s of video + text overlay | Bio link only | 3-5 trending | Video-first, captions secondary |
Load inputs. Topic, brand voice guide, platform rules, CTA requirements.
Write the hook. The hook is the single most important sentence. Delegate to hook-write for 5-10 variations, or write one directly:
Write the body:
Write the CTA. Delegate to cta-craft if needed:
Apply platform formatting:
Run brand voice check. Does the post sound like the brand or like a generic AI output? Would the founder actually say this?
## Post: [Platform]
[Full post text, formatted exactly as it should appear on the platform]
---
**Platform:** [X / LinkedIn / IG / TikTok]
**Pillar:** [Education / POV / Proof / BTS / CTA]
**Hook type:** [Question / Contrarian / Statistic / Story / Observation]
**CTA:** [Follow / Reply / Save / Link / DM / Share]
**Best posting time:** [Day + time window]
**Visual suggestion:** [Image/video idea if applicable]
**Voice check:** [Passes brand voice? Y/N + brief note]
The skill is complete when:
Read the post out loud. Does it sound human? Count filler words ("really," "very," "actually," "just") — remove them. Check character count against platform limits. Does the hook make you want to read the next line?
Input: Topic: "Most cold outreach fails because it's not personal enough." Platform: X. Goal: engagement + new followers.
Output:
cold outreach isn't dead.
it's just lazy.
"hey saw you're a founder, check out my tool" = deleted in 0.5s
here's what actually works from 10,000+ cold emails analyzed:
1/ personalize the FIRST sentence
not the last one. first.
if you open with a template line, they never read past it.
start with something only THEY would say.
2/ lead with VALUE, not your product
"i can help you grow" = spam
"your pricing page has a pricing error that costs you 15%" = meeting booked
3/ make the ask TINY
not "hop on a call"
"reply with your top metric — i'll tell you if we can improve it"
follow for more cold outreach frameworks. next post goes deep on subject lines.
Platform: X | Pillar: Education | Hook type: Contrarian | CTA: Follow
