These factors are now getting baked into the tools. Primarily via prompt engineering, and what might be called "agentic design," which is how much complexity you put into a single pass vs some hierarchical layering of agents and tools with distinct jobs.

I've been deobfuscating claude code to watch their prompts evolve as I use it and you an see the difference around how and when it chooses to re-analyze a codebase or how it will explicitly breakup work into steps. A lot of the implicit knowledge of software engineering is being added, _outside_ of the LLM training.
