Vendor protocol extension parsing

Vibe & agenticAlgorithms & data structuresMid–Senior~18 min

You're using an AI agent to generate a parser for a proprietary telecom signaling protocol (a vendor extension of Diameter) that exists only in a 200-page PDF spec and a handful of internal example captures. Generic prompts produce parsers that match the *standard* Diameter layout and silently mis-handle your vendor's extension AVPs. How do you supply context so the agent builds the right parser, and what's the core risk?

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.
