Claude Skill: Linkedin Teaser Generator For Substack

Turns a Substack article into a brand-voice LinkedIn teaser post with a strong hook, a first-comment link, and ready-to-use posting metadata.

LinkedIn Teaser Generator turns a full Substack post into a LinkedIn teaser designed to earn attention and drive clicks.

It extracts the core argument, picks the strongest angle, writes a short post in your voice.

Key Design Decisions I Took

• Link goes in the first comment, not the post body. I just recently learned that LinkedIn’s algorithm suppresses posts containing outbound links. So teasing in the post and dropping the URL in a comment significantly increases reach.

• Hook patterns are constrained to three types (bold claim, specific result, pattern interrupt). These map to the formats that generate the highest dwell time on LinkedIn in 2026, where the algorithm rewards posts people actually stop to read.

• “No cringe” list bans overused LinkedIn phrases (”game-changer”, “let that sink in”, etc.) to keep your brand voice clean. If you have a separate Voice DNA skill active, it automatically defers to that instead.​

• Structured output gives you the post, a pre-written first comment with your Substack link, and post metadata (angle used, hook type, suggested timing), so you can copy-paste in under 30 seconds.​
