Platforms: LinkedIn
Guides LinkedIn post copy creation and optimization. Use for generating publish-ready professional content. Suitable for copy agents and design agents (image specs).
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

This skill enables agents to generate LinkedIn post copy optimized for engagement. Output includes character-counted text and structure for the "See more" threshold.
Character Limits

|---|---|---|
| Post | 3,000 characters | Optimal: 1,300→,600 |
| First line (critical) | 210–235 chars | Visible before "See more"; 60–80% decide here |
| Short posts | 100→00 chars | Polls, announcements, quotes |
Optimal Length by Content Type
| Type | Characters | Use |
|---|---|---|
| Short | 100→00 | Polls, announcements, quotes |
| Medium | 300→,200 | Case studies, tips, BTS |
| Long | 1,200→,000 | Thought leadership, analysis |
| Sweet spot | 1,300→,600 | Highest engagement |
| Avoid | >2,000 | ~35% engagement drop |

| Square | 1200×1200 | Single image |
| Carousel | Up to 20 images | Multi-image post |
| File | →MB; JPG/PNG | Native uploads perform better |
| Vertical | Preferred | 88% browse on mobile |
