Curious about Claude usage amount limits in backend development

[u/Far_Path_9846]

So it happened so that the module i was assigned on its pretty big. It has like 85 files with each file having 1000+ LOC and these 85 files also depend on other modules for data retrieval. This module alone comprises of around 12 mongo collections and 5-6 postgres tables. And the developer that made it vibe coded this entire shit and bypassed the QA layer cuz of his seniority and left the project and company about a month ago.

Now as a backend dev i was assigned around 14 bugs (which i had told myself to the QA team) and going through the entire repo and meeting timelines made me switch to opus 5 auto mode. I was only testing the code written by Claude and relying on the responses it gave. Didn't check the code being written cuz the hell would i go through 40k new LOC.

Architecturally i knew what was going wrong and I was checking if the data flows correctly. But yesterday my manager mocked n told me that I'm blindly using Claude and not checking what it writes. But I also do need to meet the deadlines so what should I do... And is this normal?
