For the evals I've run (albeit, not super scientific), these memory systems did worse than the raw harness given ripgrep.
It seems like a really interesting tool and maybe future models will know how to use these tools more effectively, but yeah I remain skeptical.
The more I think about it, I suspect that either the training data or the finetuning process (or both) will have to incorporate these tools to really get benefit from them.
so your experience matches my own limited experience of starting to run evals of my own harness, which is that these specialized tools can help weak models but on the frontier they just make it slower and more expensive
I've always found memory systems icky, because it's difficult to tell whether a memory is still valid. Also, discoverability is always a concern (when is a memory relevant). This being both a code-graph and a memory system (seemingly unrelated things), actually addresses this in a novel way.
We compared a pre-release build of Graphicle's memory with 7 other memory tools (Mem0, Hindsight and others) on three public question sets. We wrote down the test rules before scoring anything, and used one open model to read and judge the answers for every tool, so it's the same setup for all of them. Details and caveats are in docs/benchmarks.md
What we haven't done yet is the thing you're really asking: does a coding agent actually finish more tasks with these tools? We could use the same agent and model on the same tasks, with and without the tool, and compare how many tasks pass, tokens used, tool calls and time.
Curious what you're using today, and what result would convince you?
I have only just begun playing around with evals for a harness I'm working on and so far I have just been doing runs of converting https://github.com/realworld-apps/realworld from one language to another
not super pleased with it
the unsatisfying answer I think is that crafting good eval environments for long runs takes a lot of time, and there are many things you'd want to verify that you cannot simply lint or test for
Letting another LLM decide quality probably isn't the only meterstick you want, either.
