Slug generation with uniqueness

Vibe & agenticAlgorithms & data structuresEntry–Mid~12 min

You need a `slugify(title)` function in Python that turns a blog post title into a URL-safe slug, and a companion that guarantees uniqueness against existing slugs in the database. You'll ask an AI agent to write both. Draft the prompt/spec — constraints, edge cases, acceptance criteria — for a first-try-correct result. What does a lazy prompt ("make a slug from the title") get wrong, especially with real-world titles?

Implement
unique_slugs(titles: list[str], existing_slugs: list[str], max_len: int) → list[str]
Examples
in[["Hello, World!"],[],80]out["hello-world"]
in[["My Post","My Post"],["my-post"],80]out["my-post-2","my-post-3"]
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.

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