Onboarding Code Explainer
Explains a pasted code block the way you'd brief a competent new hire who has zero context on this codebase: what it does, why it exists, and any non-obvious decisions or gotchas baked into it. The output is formatted as a comment block ready to paste directly above the function, making it useful as living documentation and not just a one-off explanation.
Explain this code to a new team member joining the project today. They're a competent developer but have zero context on this codebase. Cover: what this code does, why it exists (what problem it solves), any non-obvious decisions or gotchas, and what they'd need to know to safely modify it. Write it as a comment block they could paste above the function.
