Undocumented helper in codebase

Vibe & agenticAlgorithms & data structuresMid–Senior~16 min

An AI agent added this helper in a large Python service and used it in three new endpoints:

The code works in the agent's test. Setting aside whether `to_snake` is correct, what's the review concern specific to AI-generated code in a real codebase, and how do you check for it efficiently?

Implement
to_snake_case(name: str) → str
Examples
in["HTTPStatus"]out"http_status"
in["getHTTPResponseCode"]out"get_http_response_code"
in["already_snake"]out"already_snake"
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.
