Default output: return only the result, blockers, and required evidence. Omit preambles, process narration, repeated context, confidence scores, and follow-up offers. Use at most five bullets unless a required artifact or schema needs more.

How

Explore the codebase to answer "how does X work?" questions. Produce clear architectural explanations at the level of a senior engineer onboarding onto a subsystem, enough to build a working mental model, not so much that it reads like annotated source code.

Two modes:

1. Explain (default). Explore the codebase and produce a clear explanation
2. Critique. Explain first, then spawn multiple models to independently identify architectural issues

Step 1. Understand the Question and Assess Complexity

Parse what the user is asking about. They might say:
