Start with this prompt

Written for this task. Fill in the bracketed parts.

Explain this code to me.

I want to understand: [what you're trying to change or fix]
My familiarity: [new to the language / know it well but not this codebase]

Start with what it does and why it exists, then walk the main path through it.
Point out anything surprising, any implicit assumption, and anything that looks
like it was worked around rather than solved.
