My Thoughts
I find it fascinating to see how others use modern AI tooling like Claude Code.
The idea that you can configure your instructions well, almost like a well thought out onboarding, and then just get vastly better results and save tons of time is honestly not spoken about enough.
I think the highest delta thing that can be done right now is optimising your Claude code or other agentic coding setup. Not just instructions, but also, custom commands, custom skills, off the shelf MCPs, custom MCPs where needed.
This is a no brainer in terms of ROI.
I use a very specific prompt to push Claude to check its work and do a lot of testing and thinking about perf and refactoring. I find I can do big features (4K LOC+ with full testing) in about an hour.
