> simpler alternative to Skills
this concerns me. Skills are already just about the simplest possible thing; they're just prompts, in a directory!

Skills are notably more complex than that. They require metadata (which the model is given and uses to determine whether or not to load the main file), are intended to be loaded via a tool call, contain extra resources (also loaded by tool calls), etc. In contrast, with this system the harness doesn't need a tool to load the stored prompts, the prompts don't need to include metadata to allow for runtime discovery, etc.
Runtime discovery is the entire point of skills. Without it, this is just a templating prompt system that the user has to remember to use… except because this one changes your system prompt, it also busts your cache and costs you extra money when you use a prompt.
Skills are already dead-simple and this prompt system doesn’t at all tackle the same problem.
"{Feature} is the whole point of {more complex technology}" is an objection that can very often be raised. That doesn't mean that giving up features in exchange for simplicity is always the wrong call. And there's also advantages to having the user drive what instructions go into the prompt instead of the harness/model.
This is tangential to the point. It’s often great to have a simpler version of a solution, even if it eschews some features. But this isn’t that. OP claims that the prompt system is an “alternative” to skills, but it isn’t. It isn’t solving the same problem that skills solve at all. It’s like saying that a bicycle is a simpler alternative to a lawnmower because they both have wheels.
Prompts are a feature that are simpler than skills, sure, but they’re a completely different feature entirely.
It's an alternative in the same way e.g. plain markdown is an alternative to HTML, even though plain markdown lacks some of the features of HTML. "X is an alternative to Y" in this sense doesn't mean "X all the same features of Y", it means "you might reasonably choose to use X instead of Y, depending on your exact usecase"
Exactly, this was my thought process when deciding if we should have Skills or not.
In the end, I think that this prompt-only design, with the integrated tools that come with zerostack, is more than enough.
So are these lol
