Get a live SEO checklist while you write posts
A marketer had Claude Code write two add-ons that tick off search-ranking checks and preview Google results as he writes blog posts.
Done with Claude Code
What they did
The author asked Claude Code to build small add-ons that run automatically when it does something. One checks whether the keyword is in the title, a heading and the first 100 words, and flags short posts. The other shows how the title and description will look in Google results.
How it went
He says both work in plain English with no code, and the checklist resets when he switches keywords.
Worth knowing
These add-ons have the same access to your computer as Claude Code. Test one in a single session first, and don't pile up ones you never use.
Try it yourself with Claude Code
Build an add-on that runs automatically whenever you edit a blog post in [folder]. Check my target keyword [keyword]: is it in the title, a heading, and the first 100 words? Flag the post if it is under [word count] words. Also show how the title and description would look in Google results and warn if the title is cut off. Explain what the add-on can access before installing it, and wait for my approval.
Swap the highlighted [parts] for your own details.
