Built-in skill — code explanation.
Injects a system-prompt section that structures an explanation as high-level purpose → key concepts → step-by-step walkthrough → surrounding context → trade-offs, and tells the model to pitch the depth at the audience: language features for beginners, domain logic for experienced developers, edge cases for domain experts.
Activates on prompts containing "explain", "what does this", "how does this",
"walk me through" or "understand this". Group :coding;
tags :explain, :understand, :learn.
