Based on SOC occupation classification
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.

Enforce correct dimensions, aspect ratios, and safe zones for every visual asset on every platform. Wrong dimensions mean cropped images, blurry posts, and a brand that looks amateur. This skill is the single source of truth for visual specs.
Every platform displays images differently. The same image that looks perfect on X gets cropped badly on LinkedIn. This skill eliminates guesswork by providing exact specs per platform, content type, and asset format — so every visual lands correctly.
| Platform | Aspect Ratio | Resolution | Best For |
|---|---|---|---|
| X (feed) | 16:9 | 1200x675 or 1600x900 | General posts, quote cards |
| X (link preview) | 1.91:1 | 1200x628 | Link preview cards |
| IG Feed (portrait) | 4:5 | 1080x1350 | Carousels, primary posts |
| IG Feed (square) | 1:1 | 1080x1080 | General feed posts |
| IG Stories / Reels | 9:16 | 1080x1920 | Stories, Reels |
| LinkedIn Feed | 4:5 or 1.91:1 | 1200x1500 (4:5) | Carousels, single images |
| LinkedIn Banner | ~3.33:1 | 1584x396 | Profile header |
| TikTok | 9:16 | 1080x1920 | All videos |
| Platform | Aspect Ratio | Max Duration | Max Size | Codec |
|---|---|---|---|---|
| X video | 16:9 or 1:1 | 2:20 (premium longer) | 512MB | H.264 |
| IG Reels | 9:16 | 90 sec | 4GB | H.264 |
| LinkedIn video | 16:9 or 1:1 | 10 min | 5GB | H.264 |
| TikTok | 9:16 | 10 min | Varies | H.264 |
Identify the platform and content type. Feed post? Story? Banner? Carousel? Video? Thumbnail?
Select dimensions from the Quick Reference table.
Check safe zones:
Specify export settings:
If source asset is wrong aspect ratio:
Provide the format checklist for the exact asset type.
# Asset Format: [Asset Name]
## Platform: [X / LinkedIn / IG / TikTok]
## Content Type: [Feed / Story / Banner / Carousel / Video]
### Specifications
- **Aspect ratio:** [e.g., 4:5]
- **Resolution:** [e.g., 1080x1350 px]
- **File format:** [PNG / JPG / MP4]
- **File size limit:** [Platform max]
### Safe Zones
- **Top:** [N]px margin
- **Bottom:** [N]px margin (UI overlay risk)
- **Left:** [N]px margin
- **Right:** [N]px margin
- **Center safe area:** [Effective usable area]
### Source Asset Adjustment
[Cropping/extension notes if source is different ratio]
### Export Settings
- **Format:** [PNG/JPG/MP4 settings]
- **Color space:** sRGB
- **Compression:** [Level or bitrate]
The skill is complete when:
Preview at platform display size (30-50% of screen width to simulate feed view). Is text readable? Are key elements in the safe zone? Export a test post in draft mode and review on mobile.
Input: LinkedIn carousel. 6 slides. Source text: "3 signs your pricing is wrong."
