The bus factor is gonna be pretty high if your enterprise relies on an internal tool that some guy at your company vibe coded at some point.

Bus factor would be 0 because even he wont be able to debug it.

This was true pre-AI, but now, the bus factor is actually way lower in any software than it was before:

- Hey Claude, what is the project in XXXXX/ about and how does it work ? What should be improved there ?

Or even better:

$opencode

/init

Wait 20 second, then describe the bug.

AGENTS.md seems to exist not just to save tokens, but also so the Bus has to do overtime Isekaing people before a company goes down.
