ai-explain

@arcasilesgroup

Use when a developer asks 'how does this work?', 'why does it do X?', 'trace through this', 'explain this pattern', or needs engineer-grade technical explanations anchored in real codebase examples. 3-tier depth (brief/standard/deep) with ASCII diagrams and execution traces. Not for documentation (/ai-write) or fixing code (/ai-dispatch).
