Something very useful that will be harder for you most likely is code search. Having a proper index over hundreds of code repos so the agent can find where code is called from or work out what the user means when they use an acronym or slightly incorrect name.
It's quite nice to use and I'm sure someone will make a strong commercial offering. Good luck
That said, there are workarounds, like cloning all repos and enabling LSP (coding CLIs added that feature) or using a dedicated solution for codebase indexing and add a skill/mcp.
Super fast models spamming grep commands are also fun to watch!
Curious to know how you implemented it in house.
Run a copy of this in the same VPC. Monorepos would definitely help, but that's not the structure we have. I didn't want to rely on API limits (or stability) at GitHub for such a core feature.
Using this we've had agents find dead APIs across multiple repos that can be cleaned up and the like. Very useful.
One learning we had is that most of the time CLI > MCP
