[counterintuitive] more context is always better

Apply aggressive context pruning and relevance ranking before injecting text into the prompt window; limit context to only what is strictly necessary for the immediate reasoning step.

Journey Context:
Agents often dump entire codebases or long histories into the context window, assuming more information reduces ambiguity. However, LLMs suffer from the 'lost in the middle' phenomenon where they ignore relevant information buried in long contexts. Irrelevant context actively degrades reasoning by increasing the search space for attention heads, leading to distraction and lower accuracy. Precision beats recall for prompt contexts.
