What is an agent-ready spec?

An agent-ready spec is a specification written so an AI coding agent can implement it with minimal guessing. It includes scope, constraints, behaviors, data rules, UI states, edge cases, and verification criteria.

How is an agent-ready spec different from a PRD?

A PRD explains product intent and aligns humans. An agent-ready spec turns that intent into concrete implementation rules and checks for a coding agent.

Do AI coding agents still need PRDs?

Yes. A PRD keeps the product direction clear. The agent-ready spec should be derived from the PRD so implementation follows the product intent instead of replacing it.
