its not though if you're working in a massive codebase or on a distributed system that has many interconnected parts. skills that teach the agent how to pipe data, build requests, trace them through a system and datasources, then update code based on those results are a step function improvement in development. ai has fundamentally changed how productive i am working on a 10m line codebase, and i'd guess less than 5%…
But... plain Claude does that. At least for my codebase, which is nowhere close to your 10m line. But we do processing on lots of data (~100TB) and Claude definitely builds one-off tools and scripts to analyze it, which works pretty great in my experience. What sort of skills are you referring to?
Skills are crazy useful to tell Claude how to debug your particular project, especially when you have a library of useful scripts for doing so.
