I know everybody seems to want the agent to remember every conversation they've ever had with it, but I just don't see the value in that. In fact, it seems to hurt productivity to have the agent second guessing me based on something I said yesterday. Every time I've used any memory system, the agent gets distracted from the current tasks based on previous conversations and branches of development...often comingling unrelated projects (I work on code for work, open source projects, a bunch of unrelated side projects, etc.) and trying to satisfy requirements that don't make sense.
I've stopped trying to achieve general "memory". I just ask the agent to thoroughly, but concisely, document each project. If it writes developer documentation and a development plan/roadmap, as though a person was going to have to get up to speed and start working on the project, it provides all the information the agent needs tomorrow or next week to pick up where we left off.
The agent is not my friend. I don't need it to remember my birthday or the nasty thing I said about React last week. I need it to document what anyone, agent or human, would need to know to get productive in a particular repo, with no previous knowledge of the project.
Good, concise, developer and user documentation and a plan with checklists solves every problem people seem to think "memory" will solve: It tells the agent what tech stack to use (we hashed it out in planning), it tells it what commands it needs to run and test the app, it covers the static analysis tools in use (which formalizes code style, etc. in a way a vague comment I made a month ago cannot), and it is cheap. Markdown files are the native tongue of agents. No MCP, no skills, no API needed. Just read the file. It works for any agent, any model, and any human just getting started with the project.
Basically, I think memory makes agents dumber and less useful. I want it to focus on the task at hand.
I appreciate your comment, and can relate. I tested a couple of "memory" systems, doing some heavy lifting or seemingly implementation of theories (layering, hot memory, etc), I can't really tell if they improve performance, quality or reliability on a task. But they do increase the overhead, for the LLM and for me, that's for sure.
One problem I have is that now CLAUDE.md or skills tend to get version controlled within projects, I suspect they could get in the way sometimes.
There is already so much fatigue induced by these systems, adding another one willingly does sound crazy.
You still have to worry about handing off state into the next session, but you don’t want it loading (“just naive-read the files”) your stack of documents at every turn . It goes against the idea of progressive disclosure. Progressive disclosure scales.
Yeah it's that lack of perfect recall, imo, that gives rise to intelligence and progress.
If we humans just did exactly what we did yesterday, what progress?
It's baked into the immutable constants of the universe for us; entropy, signal attenuation over distances... information breaks down over time.
Because of this all human social statistics trend towards zero with intentional conservatism. Progress is or collapse is all the universe affords. It doesn't seem interested in conservatism at all.
I can't see any value in having a global memory either, but can see the value for a local memory of a specific line of work. I.e. when implementing several features in a row that are related, you want the agent to remember what it did in the last chat.
I prefer ticketing systems for AI. I dont care that it forgets what I did last week, I just need it to be able to compact its own memory and grab the next task once done.
I'm ambivalent about that. I've seen people use beads, and they're just making busy work for the agents, splitting stuff up into tiny tasks that could have been one-shotted as part of the larger plan. They seem to just enjoy making thinky machine go brrr, even when it makes the work take longer and burn a lot more tokens.
I tend to think developing with agents should look at lot like managing a human (like, I use feature-branch development with PRs and review them, even on my own projects that have no other devs and don't need a paper trail for security audit purposes), so I theoretically can get down with an issue based process, but thus far I haven't seen it done in a way that isn't just making busy work for agents.
Key things: I added a concept called "gates" which are tied to all tasks, it forces the agent to do arbitrary requirements such as: ensure it still runs / compiles, run all tests, ensure they pass, review existing tests critically and point out if they're not comprehensive enough, and finally, get human confirmation on the task. Until the human confirms, just work on another task and so on.
I didn't like that Beads was built on top of Git, I don't always work on git friendly projects, and beads kept getting messed up if I switched branches. So I made mine SQLite based. I also made it so you can sync to github issues, and sync pre-existing (and new) github issues as guardrails tasks to be worked on, the agent will even leave a comment for you on github when it grabs an issue in order to let others know the work will be done potentially.
I've had to remove any of the "knowledge" about me from any agent I use. "As a security engineer, blah blah blah" or "as a rust developer blah blah blah" even though my questions has nothing to do with those topics and they're a huge distraction.
Yeah, I've disabled memory in everything I use. It's super distracting to have it infer connections between conversations where there is none. It's also kind of sleazy feeling. Like, manipulative in the sense that it thinks it knows what I'm into so it's going to weave that into the conversation.
If we didn't have evidence that these things cause something like psychosis in some people, it'd seem innocent. But, since the sycophancy combines with the long-term relationships some people think they're having with matrix math to trigger serious mental health problems, it feels more sinister.
Anyway, having a long-term memory makes them dumber and more easily confused. I don't have any use for a dumb agent.
I planned and supervised the build of an ambient recall system, where a 4b model looks at the last 3k or so of context and picks through the RAG database for high ranking memories to inject, as well as mineable things to mark. Injections happens about 1/5 turns on most technical topics, data picked from prior design docs and data sheets mostly. At session wrapup the inference model goes back and rates all the memory injections in a frontmatter section, then looks at all the memory suggestions to commit those it finds memorable to the RAG database. Manual memorisation and RAG search are also available inline in the chat to both the user and the model. It also allows the main model to spawn little models as minions to work on repetitive simple tasks.
It strikes me as funny how we want to get super AI inteligence but keep trying to anthropomorphizing all AI aspects to make it more "human". IMHO, if we keep doing it we will create Human AI with all errors and deficiencies humans have.
Do you think humans don't have perfect memory because it's hard to achieve and millions of years of evolution haven't been able to? Or because it's convenient to forget in order to prioritize the more important recent information?
It's obviously the latter, a system that 'remembers everything perfectly' is probably not optimal in most senses. Mortality is a property of both life and artificial systems, forcing the same retention policy on new information and old information probably does so at the expense of lifespan or stability.
Well it was believed that (hu)man was made in the image of God, so perhaps reaching god involves maintaining and even furthering our human-like traits.
I think design-by-nature is consistent with seeking perfection, of course it won't ever be achieved, but organic inspirations can and often help maximize a lot of parameters.
I am also building a similar memory structure and decay mechanism for my local agent project, where I also use Ebbinghaus.
One of the challenge I face is how to decide effectively what to save in the memory: Is it the model to decide what is important, summarize and save it to the memory? How to avoid redundancy and categorize the memory correctly so you could get the right hit and decide what to forget.
I would love to learn more about your approach and what your thoughts on those points
I only use a decay function to see how "hot" a chunk is - not for forgetting old ones. What concerns me more are memory chunks with errors in them - they need to be corrected/removed by some other mechanism, not by decay (since they might get retrieved often).
on the other "biological memory" post in so many weeks, I pointed out that the decay rate shouldn't be based on a real clock but a lifetime of it's use within the coding session. Elsewise your memory fades even when there's no process change (eg, coder goes on vacation). I'm not going to check whether thats true here, but it seems like a naive first assumption thats failed conceptualization.
The other comment is that spatial memory is probably a better trigger for memory, so if you're not tracking where the coding session starts, the folders it's visits, etc, then you're not really providing a good associative footpath for the assistant to retrieve whats important for any given project.
And a neural network is really just a composed, non-linear parameterized function that maps input vectors to output vectors. Sometimes metaphors or analogies do contribute something valuable.

Seems to maybe be useful but I’m not sure yet.
It's obviously the latter, a system that 'remembers everything perfectly' is probably not optimal in most senses.

I think design-by-nature is consistent with seeking perfection, of course it won't ever be achieved, but organic inspirations can and often help maximize a lot of parameters.
What I do now is preserve all my claude code conversations and set the context from there.
This allows me to curate memory and it’s been the best way so far.
The other comment is that spatial memory is probably a better trigger for memory, so if you're not tracking where the coding session starts, the folders it's visits, etc, then you're not really providing a good associative footpath for the assistant to retrieve whats important for any given project.
You said it cuts token usage by 84% but isn't that typical for any typical chunked RAG system?
And why did you specifically chose to test against the LoMoCo dataset when there's a lot of issues with it and it being very easy to cheat?
