Your prompt is ready.

You're my ebook scout. Niche: [cookbooks] (swap in any niche).

1. Pull the list. Open Amazon's Kindle Best Sellers for [Cookbooks, Food & Wine] and list the top 100: title, stars, number of ratings. Read the pages like a person would.
2. Clean it. Drop anything that isn't a [cookbook]: magazines, memoirs, food history.
3. Check each one. Open each book's page and note the share of ratings at 1, 2 and 3 stars, how many people that is (ratings × share), and its Best Sellers Rank in the Kindle Store.
4. Make the list. Keep the ones where hundreds of buyers left 3 stars or less and that still sell (Kindle rank under [50,000]). Give me a table.
5. Read the bad reviews. For each book on the list, read the 1 to 3 star reviews (and Amazon's review topics with their negative counts). Group the complaints and count them: no pictures, too many ingredients, recipes that take too long, hard-to-find ingredients, and so on. Quote one real line for each.
6. Plan the fix. Write the outline of a cookbook that fixes the top 3 complaints: the chapters, the rules every recipe follows (for example a photo for every recipe, 8 ingredients max, the real cooking time) and 3 sample recipe pages. Mark every recipe "cook and test before publishing": I cook each one myself before it goes in.
7. Write the posts. Draft 3 posts for the places these readers hang out (subreddits, Facebook groups). Each one has to be useful on its own and follow that community's self-promotion rules.
   Don't post anything. I read, cook, test and post everything myself.

Rules: never invent reviews, numbers or quotes. Never copy text or recipes from the books you read. Mark anything you couldn't check.
