Open a journal entry and use this exact prompt:
Read journal/YYYY-MM-DD.md. For every person, project, and book mentioned, check whether a note exists in people/, projects/, or resources/books/. Add [[wikilinks]] for each match. For anything missing, create a stub note in the correct folder with just a title line and a one-line description.
This is the number one reason people adopt this workflow. What used to take to minutes of manual linking now finishes in seconds. I see connections surface that I would have missed entirely. Try it on one journal entry and you'll understand why backlinking automation is the first thing every new user reaches for.
One thing to watch: entity disambiguation. When Claude sees "Amazon" it picks one meaning. If you mean both the company and the river across different entries, add a line to your prompt specifying which folder disambiguates. For example, "Amazon the company goes in companies/, the river goes in places/".
