The LLM doesn't need to read the whole file in example 2). Why would it?

Where would it inject the code?

Presumably, the same MCP tool allowing it to read specific definitions would also allow it to write out specific definitions (rather than, again, having to write out the whole file just to make one change). Otherwise it defeats the purpose.

This is the same way humans work on code. You never read an entire file top to bottom just to find out one thing, and you never type out the entire file just to make one change. This would, understandably, be very taxing on your working memory, and you'd probably make more mistakes.
