It's not too late to jump on the Cocaine-Driven Development Orchestrated by LLMs train.
Either way, OP is holding it wrong and vague hypebro comments like yours don't help either. Be specific.
Here's an example: I told Claude 4.5 Opus to go through our DB migration files and the ORM model definitions and point out any DB indexes we might be missing based on how the data is being accessed. It did so, ingested all the controllers as well and a short while later presented me with a list of missing indexes, ordered by importance and listing why each index would speed up reads and how to test the gains.
Now, I have no way of knowing how exhaustive the analysis was, but the suggestions it gave were helpful, Claude did not recommend over-indexing, and considered read vs write performance.
The equivalent work would have taken me a day, Claude gave me something helpful in a matter of minutes.
Now, I for one could not handle the information stream of 20 such analyses coming in. I can't even handle 2 large feature PRs in parallel. This is where I ask for more specifics.
