How is this different from what's built into Claude?

Cool idea. Why is this beneficial over just using markdown files and allowing agents to grep for whatever they need? I've tried various MCP things in the past and I've found they tend to slow down the agent and waste tokens more than they end up helping, but a better memory system is 100% needed for agents.

for one, the mcp-server architecture makes it usable from claude.ai and other surfaces where you have mcp but no filesystem. there are claude-specific workarounds (workspaces) but you lose portability across systems.

How is this any different from all the other Memory stuff we have? mem0 etc etc that do the same thing?

Nice to see more OKF-based approaches. My entry in this field is https://rcarmo.github.io/projects/memento/, which I’ve been running for a few months now.

Please excuse my noob-ish, naïve question, but to what extent is the business of getting the LLM to actually consult memory a model-dependent thing? Do you have to introduce the tool and guide models with different language for different model families?

Looking at your tool descriptions (as wit the ones on the original post) I wonder if this something perhaps only current frontier models will do, but the systems themselves seem like they'd be even more useful for open weights models with shorter working contexts.

Since you built something on OKF, how would you contrast it with knowledge graph implementations? How do you manage the ontology of what to keep knowledge about? Any cases where traversal would have helped?

I have seen the value of recording past sessions but I am more skeptical of the value in recording facts, which may soon become stale, about a constantly changing code base. Got benchmarks?

Well, do you see the value of writing notes for yourself occasionally, even though they might soon become stale in your constantly changing environment? Yes, right?

Same principle. It's a good idea to have a schedule to clean them up periodically - an idea you can also put into a note.

Looks very interesting. Can you explain for noobs why using Google's OKF format and not plain MD files?

pcbmaker20 an hour ago | parent [-]

OKF is basically md files with front-matter for meta data

did you test if that actually outperforms local claude code memory by any metric?

rgbrgb 13 minutes ago | parent [-]

that's a good idea. how might you test this? could also include a codex memory test.

I'm guessing having a portable memory that's comparable with first party memory is the goal.

Using SQLite FTS5 for fast agent memory is such a pragmatic architectural choice. Great Show HN project.

Another week, another agent memory system that is about the same as grep in a memory/ directory.
