API integration scaffolding

Vibe & agenticAI agents & automationMid–Senior~14 min

Your team integrates with a lot of third-party APIs, and someone wants an agent that scaffolds each new integration — client code, retries, error handling. The catch: language models happily invent endpoints that don't exist. Design the agent so hallucinated APIs can't reach the codebase: what grounds its generation, what it's forbidden to fabricate, and what a human still owns. How would you verify its output systematically, and why is this worth building versus copying the last integration?

Implement
find_ungrounded_calls(spec_endpoints: list[str], generated_calls: list[str]) → list[str]
Examples
in[["GET /v1/users","POST /v1/users","GET /v1/orders/{id}"],["GET /v1/users","GET /v1/invoices"]]out["GET /v1/invoices"]
in[["get /v1/users"],["GET /v1/users/"]]out[]
in[[],["GET /health"]]out["GET /health"]
What a strong answer looks like

Turn the fuzzy goal into a bounded agent task. Say what the agent reads, what it may do on its own versus draft for a human, and what it must never touch. Then earn the trust: how you’d verify it before rollout, and the pitch (the problem, what you built, why it matters).

Agent build: design the agent in plain language (or narrate it). The coach grades the decomposition, the guardrails, the verification plan, and the pitch.

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