 # Instructions for AI Agents
 
 - After your changes, instead of running specific tests or linting specific files, run "pnpm format && pnpm lint && pnpm test". It means that you first format the code, then lint it, then test it, so that no part is broken after your changes.
-- Don't leave comments that don't add value
-- Do not duplicate code unless you have a very good reason to do so. It is important that the same logic is not duplicated multiple times

 - Before finishing the task and showing summary, always run "pnpm format && pnpm lint && pnpm test" at the root of the project to ensure that you don't finish with broken application.
