Ive been working with Python and Go backends for like five years now, so I definitely know my way around a codebase, but lately Ive been messing around with Claude Code for my personal projects and its honestly kind of a trip. I have this side project, basically a microservice architecture for a local inventory tracker I need to wrap up in the next three weeks before my cousin opens his store, and I keep getting stuck on the boilerplate stuff.
I feel like Im underutilizing the tool though. Like, it writes decent tests and can refactor simple stuff, but I bet there are way better workflows for actual complex backend logic. Are there specific prompting patterns or configurations you guys use to get it to handle database migrations or complex ORM relationships without hallucinating weird foreign keys? I dont have a huge budget for api credits so I really need to get the workflow tight. Should I be feeding it specific architectural docs first, or is there a trick to keeping the context window focused on just the service layer changes? What are the actual power user skills I should be grinding on to make this thing move faster...
Honestly, stop feeding it the whole repo. Claude Code eats tokens like crazy, and if you dont watch your usage, that budget is gonna vanish. I suggest you keep your context window lean by only pointing it at specific files or generated documentation summaries.
For migrations, stop letting it guess keys. I usually feed it the raw SQL schema and a summary of my JetBrains DataGrip 2024.3 IDE export. It keeps the foreign key relationships accurate without hallucinating. If you want to keep costs down, just define your interfaces clearly first. Honestly, it handles boilerplate way better when I use Postman Professional API Development Suite to pre-generate the request payloads. Saves me a ton of tokens during testing.
Subbing for updates
Late to the party but lsymyndhfg is totally right about the context window. Honestly, I've had issues with the tool hallucinating fields way too often when I let it roam free. It is definitely not as good as expected for complex migrations, unfortunately.
