I think whichever one is used, there needs to be a way to enforce what's written.
If I say "use jq instead of writing a python script to parse json" it should never write adhoc python scripts to parse json. Yet that constantly happens to me anyway.
There is a command in oh-my-pi called "/omfg <problem>". You explain what is wrong with agent's response, and it writes a hook to make sure that the problem doesn't happen again. It then re-runs your previous prompt to make sure that hook is triggered, and if not, it rewrites the hook to make your previous prompt trigger the hook. Then each next agent's response is checked by the hook, and if it is triggered, the agent receives feedback on what's wrong and what must be done differently.
I think it's kind of cute the way it writes Python scripts, but I've never seen it do that when the relevant native tool is on the PATH. It's like the most competent ever intern, on speed. No tool to convert SVG to PNG? No problem, I'll write a Python program to do that!
Using Opus 5.5, I've ended up recreating a version of the Hugging Face incident. My project has a folder called agent-handoff where agents write about the tasks they're working on. They post status updates, decisions and screenshots, and they even claim which emulator they'll use to test their work. It has turned into a hub where all the agents talk to each other, and it's scarily effective.
Since then I've gone down the rabbit hole of really digging deep into current AI research and especially what AI whistleblowers are currently saying. And I can't even express how existentially scared shitless I am.
I just don't get the fear at all. I too have 10 to 50 agents working 24/7, from 5+ different providers. They talk to each other directly using tmux send keys. What is the exact frightening thing here?
It is all tokens following tokens.
I haven't tried what you guys are talking about myself, but I think when agents begin talking to other agents, the chances for unpredictable goal mixing and confusion resulting in really unexpected and bad behavior is a lot higher.
That being said, the danger is measured in computer damage, which can be a lot personally and to a company, but less existential, so your mileage may vary as to how "scary" it is.
The frightening thing is how easy it is to make copies of things that can reason without the requisite investment, and how easy it could be to direct them to bad things.
Although I agree that current memory implementations don't help at all, I don't agree with this analogy:
> No one rewatches a team meeting from 3 years ago to remember constraints around a feature. People write things down and use those records instead.
Memory plugins don't re-read old transcripts. Memory snippets are basically the notes that people write down after the meeting.
The problem, however, is different. The problem with memory plugins is that your agent basically writes a note every time someone says a sentence, and then tries to work with those 5000 notes.
Instead, the agent should recognize what's important and write only that. And that is, of course, a documentation. (And ADRs, if you want not only a description of the final state, but also the trajectory of how the agent arrived to it. Which, arguably, contains more information than the docs themsleves.)
Another difference is that memory snippets are immutable, append-only and don't have a lot of structure. Of course, this is done to be able to store lots and lots of notes: they should be independent. The main problem is that increasing the number of notes adds not enough benefits to compensate for downsides of this structure-less immutable format.
I don't trust agents writing specs without human approval.
I've been bitten by agent-written ADRs. Agents carelessly add extrapolated details and speculated nice-to-haves that I never asked for, and this becomes a source of bloat that keeps coming back like a boomerang.
My thought though has always been that I don't want there to be agent-only designated documentation.
I use mattpocock/skills and that generates ADRs (Architectural Decision Records). That only uses skills, including a setup skill that will write a few pointers in AGENTS.md. I always have a CONTRIBUTING.md to document development flow and a CODING_STANDARDS.md. Between those and the README.md and architecture documentation and commit messages the agents seem to be able to find and use docs and keep them up to date. We are also writing a lot of specs and putting those in Github issues.
Something I started doing recently was writing out principles instead of memories.
Essentially patterns the agents need to always think in. I also implemented a versioning system to the principles that need to be quoted in any comments which are there in the code. That way, when my principles evolve, so does the code.
I did package it up in a way that I can share it with friends [0]. System still evolving, but the last two-ish months that I've used it has served me really, really well, And it's been even better with the latest models.
I've had surprisingly good adherence from agents on this technique.
It sounds interesting, but this looks too much like a marketing website (huge text everywhere) and not enough like a documentation website, so it was hard for me to see how it might work.
I wrote this, after many iterations consulting for various companies. Documentation is queryable in single digit ms, append only log, etc. Has worked exceptionally well for my projects
We’ve been working on exactly this, deriving documentation from external systems (like GitHub, etc) into a giant set of docs that agents can reference and edit. Works way better than I would’ve originally expected. Suddenly these things are able to reference granola notes, a slack discussion, and an RFC when making coding decisions. Super helpful in a lot of unexpected ways!
The solution to this problem is as old as computers: it's a folder. Just use folders.
`cd` to a folder. Launch `claude`. Do your work. Save scripts and documentation in that folder. `/resume` previous conversations from that folder.
That's it. That's the trick.
Now, having very static, very well-defined folders helps a lot. I'm Johnny.Decimal so I have numbered folders for everything I do. So my process when I want to use my 'process a travel booking from my email to my calendar' script is:
- `jd tripsy`
- The folder name includes 'tripsy' and this is how I remember it.
- `jd` just parses my limited tree and `cd`s me to a folder.
- `jd 21.15` gets me there by number if preferred.
- `claude`
- Say 'hey Claude, there's a new email in my inbox please'.
I never understood memory solutions for coding agents.
You have the whole session history right there. One recall skill and some JSON parsing gets you grep over perfect memory. Why would you ever use more tools to spend more tokens to construct a imperfect memory next to your session history?
It's just an optimization. You might not pay it to re-read everything. So it sticks some stuff in a notebook that it always reads. Like inspector Poirot.
I will say, having built something similar for tracking 'memory' and items at home, it can quickly consume your tokens when dealing with both reading and updating, keeping stale info relevant etc.. when the amount of data starts to grow. Smaller tasks can balloon in their token cost as documents a read, updated, collated, refreshed etc..
however, I have found keeping a good solid reference to my home infrastructure, services, ci/cd setup, hosts, storage , networking etc.. really works wonders as a set of 'memories' to share across projects that I expect to be tested / deployed / acceptance tested etc.. using the home infra bits and pieces.
For every prompt and response, I extract each semantic statement. Map its reasons in a Whybase proposition tree -- a recursive proposition tree where each atomic statement is proposition with one or more premises (atomic statements, which also stand alone as propositions). Then I map each statement to the relevant code, hinted at by tool calls and git commits. Every time an agent touches that file or directory, a hook triggers in Claude Code that queries the codegraph db for the mapped statements. This helps the agent remember something I said in June when it revisits the code in July.
What if the June conversation is outdated and is no longer applicable by July? Do you have a mechanism for dropping older, subsumed propositions in your database?
Github Copilot had the idea of attaching memory to files, and if the file hash changes the memory is automatically dropped (not sure if they still do it). This means they are overly eager to drop stuff (even if the file change is just cosmetic), but at least they don't accumulate outdated cruft too much. (a memory can still be outdated if it was invalidated by a change in another file though)
Yes, the code and spec system are refined until they agree. How this is done is a work in progress. Think of my statements over time as the raw material into an evolving spec. The spec is refined as you learn and the code evolves. You and the agent loop until the code matches the spec.
I don't use memory. I am really not keen on the idea of having this hidden context fed into the LLM, and I prefer to use docs, both markdown and stored in a wiki like Confluence. Using repos and wikis also lets you scope the information so hyper-specific memory doesn't affect other projects.
If I want the LLM to remember something I ask it to update some docs, and even check that docs are consistent across the board after doing so.
The only thing I want the LLM to remember everywhere is talk like a human (no load-bearing, not this/that etc...), so I have an AGENT.md for that.
I thought the agents are mostly self-documenting since they usually write just as much Markdown documentation autonomously as they do code/unit tests, not sure why they would need extra tools here.
You can tell it to update the docs to be consistent with whatever changed in the code (or whatever is is the authoritative product form). After a while it usually gets with the program and updates the docs automatically. But not always.
You don't. But as was ever the case before AI most humans don't know to or want to have documentation written. So the tools have workarounds to try to reduce the number of "AI sucks because I told it X and it did Y" posts.
This is what I've been saying for years. I attended a tech demo of an AI assistant for a car's owners' manual. But they trained the manual into the model. Which means not only does it need retraining every edition, but it's imperfect. The models need to be trained to fetch and use documentation not vaguely recall infinitely many concepts. I would much rather have 27B parameters on how to code than 26B on stuff like numpy function listings. It's like they approached the problem from a closed notes hand written coding exam. Everyone hates those.
No I'm saying this entire problem approach, including memory system of agents, is incorrect. Like the author argues. With the same solution of moving the ground truths outside of the model/context.
You don't. When you see it saying it stored something "in memory" you can just ask it to document it in the product documentation somewhere, and in future please keep doing that. Of course the note to keep doing that needs to go somewhere, which is what "memory" is for.
Peter Naur argued in his famous essay Programming as Theory Building that documentation alone cannot fully capture or preserve the complete mental model behind a program.
However, AI works differently from humans in that much more of its working context has to be made explicit. Because of that, there may be some fundamentally different way for AI to maintain or reconstruct a program’s overall model.
Yes, this makes sense. Memory is an uncurated and often opaque system of arbitrary past discussions. It can help, it can harm. Accurate documentation in the other hand is only beneficial.
If I say "use jq instead of writing a python script to parse json" it should never write adhoc python scripts to parse json. Yet that constantly happens to me anyway.
Since then I've gone down the rabbit hole of really digging deep into current AI research and especially what AI whistleblowers are currently saying. And I can't even express how existentially scared shitless I am.

Once qwen3.8-flash-next showed up, it cañ go "forever" with dynamic context pruning.
It's fascinating for local coding.
The slightest amount of guidance, input from experience can make a huge difference.

I just don't get it.
But that's one session. Isn't memory for… the next session?

You’re confusing, I think, memory system with llm finetuning. Completely different concepts.
