What's Wrong?

Just getting totally fruistrated of the bullshit.
I got a project i am working on for a month based on supabase and a database designed with explanation of fields.
Claude code is creating new fields without taking in Account the previous data AND wants to use NEON to check the data. NEON is used in another project nothing related to this one, separated folder etc...
Today i passed 4 hours of checking it s stupid activities, like if it was made on purpose to consume credits.
if that is the future, better die young.

What Should Happen?

it should do as told, not creating unnecesary fields, wanting to use another database system never mentionned in the project, avoid deleting more than what is really linked to the problem

Error Messages/Logs

I hear you. I messed up on multiple levels:

Neon — I should have known this is a Supabase project. That was completely wrong.

Fields with different names — I don't want to guess and make it worse. Which existing columns in the orders table map to the fields in the form? So I can fix the update query to use the correct column names instead of creating new ones.

Refund — You can report issues and request support at https://github.com/anthropics/claude-code/issues
