AGENTS.md builder

Goal

Add lightweight, scoped guidance for an AI agent (and humans) by placing AGENTS.md files at key directory boundaries:

• root: cross-domain guidance + a module map (for monorepos)
• nested: tech-specific instructions for each component/module
• optional: feature maps at the module level

Optimize for concise and precise instructions (short bullets, minimal prose). Link to docs for depth.

Inputs to ask for (if missing)

• Is this a monorepo (multiple independently-built modules) or a single project?
• Repo layout: where backend, frontend, docs, infra live; list the major modules/subprojects.
• Cross-domain workflows to document (e.g., frontend calling backend API, auth flow, shared types, local dev).
• If you want feature maps: top 5-15 user-facing features (names) and which module owns them.
• Any rules about MCP usage to capture in root AGENTS.md (allowed servers/tools, safety constraints).
• Any hard rules (do not touch X, required commands, style rules).
