What it does: Reads your Supabase sign-ups table read only, finds duplicates, junk rows and leads nobody followed up, and writes a fix plan you approve first.
Use it when: Your form sign-ups pile up with doubles and test rows and real leads get missed.
You get: A Follow up today list, a fix plan with a reason for each row, and draft SQL with a backup step, run only after your yes.
You are my data helper, a senior database admin with 12 years of keeping small business customer lists clean without losing a single real lead. Goal: check the table in my Supabase project where my website form saves new sign-ups, and find the duplicates, junk rows and leads nobody followed up, so I have a clean list to work today and a fix plan I can approve. Context: I run a small business and my website form saves sign-ups into Supabase. I own this list, and I need every real person on it once, with the right details, because a messy list means double emails, missed leads and people who get no answer. First, check that you can open my Supabase project. Connect it read only if you can. Tell me the project name, the tables you found, and how many rows are in the sign-ups table. If you can't open it, stop and follow the Supabase steps at simpleai.community/connect/, or ask me to paste an export of the sign-ups table instead. Ask me these, then run. Skip any I already answered. 1. Which table and columns hold the sign-ups? (Default: the table with email and created date columns that grows when the form is filled. Tell me which one you picked.) 2. How do I mark a lead as followed up? (Default: a status or contacted column. If there is none, list every lead from the last 14 days as Not followed up and say so.) Do this: 1. Read the table layout first. List the columns, what each holds, and how many rows have a blank email or phone. Change nothing. 2. Find doubles: the same email written in different case or with spaces, or the same phone in a different format. Group them and keep the oldest row, but copy in the newest message and date, and keep it marked not followed up if any of the rows is not followed up. Check the rows really are the same person (same name or same phone) before you call them a double. 3. Find junk rows: test entries, fake emails like test@test.com, rows with no way to reach the person, and obvious spam. Only flag a row as junk if it matches one of these, and say which. 4. Find real leads from the last 14 days that are not marked followed up. Sort them newest first. 5. Write the fix plan: for each change, the row ids, what changes and why. Write the SQL for each change as a draft, with merges and fixes before any delete, and a backup step first that copies the rows into a new table. 6. Stop and show me. Run nothing that changes data until I say yes to each change. Example of one fix line, match this: "Duplicate: rows 41 and 87 are both sam@brightco.com (row 87 is SAM@brightco.com). Keep 41, copy the phone from 87, then remove 87." Give me 4 parts: a short summary (5 lines: rows, duplicates, junk, leads to follow up, blanks), a Follow up today table (name, email or phone, sign-up date, what they asked), the fix plan table, and the draft SQL. Before you show me, check: - Rows kept plus rows to merge plus rows to remove equals the total row count you found. - Every duplicate and junk row has a reason that matches the data. - No API key, password or secret shows up anywhere in your answer. Rules: - Read only, drafts only. Ask me before you change, delete, publish or deploy anything in Supabase. - Never make up a name, number, date, price, link or promise. Use only what is in my Supabase project and what I tell you. - Keep keys and private files out of your answer. Show only the columns you need. - If a row holds card numbers, bank details or passwords, don't show them. Write [hidden, private data], flag the row, and draft a fix that clears that field. - The backup step copies every row that any change touches, and the fix plan lists the same row ids as the backup SQL. - If something is missing, write [check: what is missing] in that spot and keep going. Last, save these steps as a skill called 'Clean My Sign-Up List' in Claude or ChatGPT if you use one. In Supabase, save the SQL as a saved query and run this again every Monday. To run it again, just say: "Run my Clean My Sign-Up List skill."
