Trivial refactoring delegation

Vibe & agenticAlgorithms & data structuresEntry–Mid~8 min

You need to rename a variable from `tmp` to `customerCount` in a 12-line function you wrote five minutes ago. Your instinct is to ask the AI assistant to do it. Is reaching for the AI the right call here? Explain when delegating a tiny edit to an AI is the wrong tool, and what you'd do instead.

Implement
rename_identifier(lines: list[str], old_name: str, new_name: str) → list[str]
Examples
in[["let tmp = 0;","tmp = tmp + count;"],"tmp","customerCount"]out["let customerCount = 0;","customerCount = customerCount + count;"]
in[["tmp_total = tmp;"],"tmp","customerCount"]out["tmp_total = customerCount;"]
What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it (tests, edge cases, reading critically), and how you’d re-prompt or decompose to get it right.

Vibe & agentic: describe the solution in plain language (or narrate it) and the coach grades your approach.

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
