There's a comfortable thing people say when they see an AI agent query a code map.
"Nice crutch. For now."
The logic underneath it is reasonable. Coding agents are young. Context windows are small and getting bigger. Models are dumb today and will be smart tomorrow. So a structural index, the thing that hands the agent a dependency graph it would otherwise have to reconstruct, looks like a patch over a temporary weakness. Wait two releases. The model will just hold the whole repo in its head and the map becomes a quaint workaround, like a spellchecker for someone who learned to spell.
I build one of those maps Sense. I went looking for the data that would kill it.
I didn't find it. I found the opposite.
