[counterintuitive] More context always improves AI coding accuracy

Aggressively curate context to only directly relevant dependencies and signatures, rather than stuffing entire files or repositories into the prompt.

Journey Context:
Humans intuitively think more information reduces hallucinations. However, LLMs suffer from the 'lost in the middle' phenomenon. When context is overloaded with irrelevant code, the attention mechanism is diluted, and the model actually increases hallucinations or ignores the crucial instruction. A human can skim a 1000-line file for the one relevant function; an LLM gets distracted by unrelated patterns in the other 999 lines, degrading its performance.
