This. MCP/tool usage in agentic mode is insanely powerful. Let the agent ingest a Gitlab issue, tell it how it can run commands, tests etc. in the local environment and half of the time it can just iterate towards a solution all by itself (but watching and intervening when it starts going the wrong way is still advisable).

Recently I converted all the (Google Docs) documentation of a project to markdown files and added those to the workspace. It now indexes it with RAG and can easily find relevant bits of documentation, especially in agent mode.

It really stresses the importance of getting your documentation and processes in order as well as making sure the tasks at hand are well-specified. It soon might be the main thing that requires human input or action.
