You can generate agent rules from a PRD and RFC by running a tool that reads PRD.md and RFC.md to determine project scope and automatically creates root and per-directory agent rule files based on the extracted conventions.

Creating per-directory agent rules involves parsing the RFC.md sections to populate specific conventions, then generating individual agent files alongside a root agent file to define behavioral rules for different project components automatically.

Yes, the agent rule generation process detects the specific AI tool being used and generates the appropriate configuration files, automatically creating either CLAUDE.md or AGENTS.md files depending on the detected environment.

Yes, you must have existing PRD.md and RFC.md files in your implementation directory, as the agent rule generation process strictly requires these documents to exist to read project scope and populate behavioral conventions.

A limitation of automating agent rule files from RFC documents is that the generation strictly depends on the structure of your RFC.md sections to populate rules, meaning incomplete or unstructured RFC data will result in inadequate agent conventions.
