Monorepo documentation that stays useful during AI-assisted work
Monorepo docs should help both humans and AI agents understand boundaries, ownership, and architecture before changes begin.
Monorepos reduce repo sprawl, but they do not remove the need for clear architectural boundaries.
As AI-assisted workflows become more common, monorepo documentation needs to do more than describe the codebase at a high level. It needs to guide navigation and safe editing.
What good monorepo docs include
Useful monorepo docs explain boundaries, dependencies, and ownership in a way that helps someone move from feature intent to the correct slice of the tree.
- Which packages own which behaviors
- Where shared infrastructure lives
- How changes should flow across the graph
Why this matters for AI
AI agents are better when the repo gives them a map. Without that map they tend to make local edits that miss system-level consequences.
