ive beeen experimenting with this for a while, (im sure in a way, most of us did). Would be good to numerate some examples. When it comes to coding, here's a few:

- compile scripts that can grep / compile list of your relevant files as files of interest

- make temp symlinks in relevant repos to each other for documentation generation, pass each documentation collected from respective repos to to enable cross-repo ops to be performed atomically

- build scripts to copy schemas, db ddls, dtos, example records, api specs, contracts (still works better than MCP in most cases)

I found these steps not only help better output but also reduces cost greatly avoiding some "reasoning" hops. I'm sure practice can extend beyond coding.
