The finding that self-generated skills provide negative benefit (-1.3pp) while curated skills give +16.2pp is the most interesting result here imo. Big discrepancy, but makes sense. Aligns with the thought that LLMs are better consumers of procedural knowledge than producers of it. +4.5pp for software engineering is suspiciously low compared to +51.9pp for healthcare. I suspect this reflects that frontier models alre…

And that's why my whole schtick when it comes to agent design is that agents need to learn online, continuously, and in adapter space via some PEFT mechanism (I like soft prompts and prefix tuning), because it's really hard to ascend gradients in discrete domains like tokens.

> The model knows damn well when it's written ugly code. You can just ask it. That's not been my experience at all, what model and prompt would you use for that? Every single one I've tried is oblivious to if a design makes sense or not unless explicitly prompted for it with constraints, future ideas and so on.

The problem is that the model doesn't know what you mean by "bad code" a priori. If you list specific issues you care about (e.g. separation of concerns, don't repeat yourself, single responsibility, prefer pure functions, etc) it's pretty good at picking them out. Humans have this problem as well, we're just more opinionated.

We had a measurable shift when we started doing ai-coding loops driven by evals. By definition, the additions make the numbers go up-and-to-the-right. It's the epitomy of "you get what you measure" :)

Chaos Congress talk on this from a couple months ago, jump to the coding loops part: https://media.ccc.de/v/39c3-breaking-bots-cheating-at-blue-t... . The talk focuses mostly on MCPs, but we now use the same flow for Skills.

This kind of experience makes me more hesitant to take on plugin and skill repos lacking evals or equivalent proving measurable quality over what the LLM knows and harness can handle. Generally a small number of things end up mattering majorly, but they end up being pivotal to get right, and the rest is a death by a thousand cuts.

The biggest gap in this paper is the condition they didn't test: Skills built through human-AI collaboration. They found fully self-generated Skills are useless (-1.3pp) and human-curated ones help a lot (+16.2pp), but that's a false dichotomy. In practice, especially in tools like OpenClaw, skills will emerge iteratively: the AI drafts procedural knowledge while solving a real problem, the human refines it with domain expertise. Neither produces the same artifact alone. The +16.2pp from curated Skills is likely the floor for this approach, not the ceiling. Would love to see a fourth condition.

I think self-generation of skills might be useful if it's based on model doing websearches, experiments in a sandboxed environment and putting into skill what it found out.

Also generating skills using top of the line model to keep using them later in cheap open weights model seems like a good use of resources.

Online sharing of skills generated in such manner also seems like a wonderful idea.

Sincerely, perhaps you should publish on arxiv before a researcher reads it to run it and write a study. It's fairly common we notice these types of threads where one thing is being postulated and then there's comments upon comments of doer's showing what they have done.

somehow sad that some random dude on hn seems to have more brain than most scientists publishing on something about agents or prompting.

we should give a little more credit to the readership of HN. I'm not sure it's that much lower than the average academic publishing on arxiv.

In general terms, we get these kinds of results that seem to indicate that LLMs can’t really “create” new information using inference. LLM generated skills don’t help. Training on content that was generated by LLMs causes models to collapse or something. It seems like it is accepted as really intuitive.

But it seems pretty surprising to me. The training corpus contains so much information and the models operate at the level of… a bright novice. It seems like there obviously ought to be more insights to derive from looking harder at aspects of the corpus.

Why isn’t this considered astonishing?

The training corpus is only learned very approximately and poorly during pretraining. You can use inference-time compute to try and cope, but this can at best make you somewhat more self-consistent; it cannot recreate info that you didn't learn effectively to begin with!
