Is codemaps useful?

[SI-IC]

Should I use codemaps command? If yes, what is the benefit?
Thanks

Yes, but mainly once the repo stops being trivial.

Codemaps help in four cases:

1. onboarding into a medium or large repo
2. handing work between sessions, agents, or models
3. refactors where you need a token-lean architecture snapshot
4. keeping context focused instead of pasting raw tree listings

My rule of thumb is:

• small repo: optional
• multi-surface repo or product: worth it
• before a big refactor or review: definitely worth it

If the repo is tiny or changing hourly, the maintenance cost can outweigh the value. In that case I would regenerate only after meaningful architecture changes.
