Your AI-written LinkedIn posts sound like AI because Claude doesn't know how you write. Generic skills make generic outputs. Fix: feed Claude 5 of your own best-performing posts as a custom skill. Five minutes to set up. After two passes you'll ship 8 out of 10 posts without edits.
Grab 5 of your best LinkedIn posts
Paste them into this skill file
Download here: Write-like-me
Open the file, paste your 5 posts where marked, save it to your Claude/Skills
Try it. In Claude, attach the skill, ask "Write a LinkedIn post about [topic] in my voice."
Total: 5 minutes
The next posts may surface edge cases. Tweak the skill once or twice to get to 90% of post automation.
