btw, if you want to speed up the build times you should look to use RE API or Goma. it can make a build finish in about 15 to 30 minutes and caches changes to speed things up further once a full build is completed.

It seems like gemini 2.5 is pre-trained on chromium given it has a lot of context into the current state of the codebase. That may help a bit.

Also, I've not tried this yet, but maybe using an MCP server over a clangd language server is a solution to the context problem?
