Trust outside your domain

Vibe & agenticAlgorithms & data structuresSenior–Staff~20 min

You're a strong application engineer with no networking background, and you ask an AI agent to write a C program that parses incoming packets from a raw socket for a telemetry collector. The code looks clean and runs against your test pcap. Given that this is a domain you genuinely don't understand, how much should you trust the result, and what's the honest move when you can't personally judge correctness?

Implement
parse_telemetry_packet(packet_bytes: list[int]) → list[str]
Examples
in[[1,2,3,10,20,30]]out["version=1","type=2","length=3","checksum=60"]
in[[1,2,5,10,20,30]]out["error=length_mismatch"]
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.
