Describe the codebase shape
Module count and dependency count set the raw size and surface area to map.

How it works
Check the two safety signals
A documented entry point and existing tests both make a codebase far easier to explore safely.
Get a map-ability score
The four inputs combine into a 0-100 score with the biggest friction point called out first.

Frequently asked questions
Is this a substitute for actually reading the code?
No — it's a quick gut-check on how much friction a new contributor or coding agent should expect before diving in.
Why does entry point clarity matter so much?
Without a documented entry point, every new reader has to reverse-engineer where execution starts, which is the single biggest source of onboarding time.
What if I have many modules but they're well organized?
The score is a heuristic based on raw counts — use the next-steps guidance to judge whether your organization already compensates for a high module count.
Does test coverage really affect map-ability?
Yes — tests document expected behavior in a way comments can't, and they let you verify an AI-generated change safely once you've mapped the code.
