[counterintuitive] Large context windows mean AI can understand the whole codebase if you just paste it in

Use RAG or targeted context injection; do not rely on massive context dumps for reasoning tasks, as LLMs exhibit 'lost in the middle' degradation and fail to synthesize information from the center of long contexts.

Journey Context:
Humans intuitively think 'more context = better understanding.' For LLMs, massive context leads to attention dilution. They retrieve facts from the beginning/end well, but fail to reason about constraints spread across the middle. A senior engineer synthesizes 10 conflicting constraints; an LLM with 100k tokens will often ignore the 5th constraint if it conflicts with the 95th, leading to confidently incorrect code that violates a subtle requirement buried in the prompt.
