Most of the cli tools just wrap an LLM, but don't give it access to the data it needs to be useful. Aider is an exception of course - it gives great results because it feeds the LLM your source files.

We built http://github.com/robusta-dev/holmesgpt/ to investigate Prometheus/Jira/PagerDuty issues. We're able to get pretty good results (we benchmark extensively) because we use function-calling to give the LLM read acess to relevant data. I think we're the only open source AIOps tool, and the only AIOps tool period that does something more complex than RAG + summarization.
