Question

You're having an AI agent build a Rust CLI that bulk-renames files by a user-supplied pattern (think a small `rename` tool). Write the spec that makes it safe and pleasant to use. What behavioral contracts, flags, and failure modes must you specify — and what does a casual 'write a file-rename CLI' prompt get wrong?

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.
