I feel like this might be solving a real problem (agents having identity, access controls, etc that are provisioned like you would a regular user) — with this Nostr layer that doesn’t really provide any specific value that I can see. So actions are signed, great — this is like telling me I’m going to be using blockchain to store my files because I need crypto on top of my crypto. We see where that ended up. Is Nostr…

I like that using keypairs and signed messages inverts the centralised server and SaaS model and makes things more local/client first. I wish more products would move that way.

Nostr seems like a reasonably convenient way to achieve that without building everything from scratch, but maybe there a better ways?

Can’t anyone already do that with a screenshot or a log dump? I’m always assuming company provided comms platforms are fully readable by the admins

That's a good operating assumption, and I usually think this way too. It turns out Slack actually requires legal process or consent of parties to provide private messages to admins: https://slack.com/help/articles/204897248-Guide-to-Slack-imp... But of course yes, another party could simply take a screenshot

They certainly can on Business and Enterprise plans. There’s some lip service to following employee policy and applicable laws, but if the policy allows (most do), and you’re in the US, the admins can do it.

I think I'd rather retire than use that.

Private groups are the worst thing in a truly collaborative environment. Would be nice in Slack to have a Publish this whole freaking thread to a public channel button.

But who is allowed to press it? If anyone, then anyone can expose career ruining messages from someone else, even inadvertently.

Who would put a career ruining message on slack or any other company platform/service?

nostr solves for who owns the shared service. nobody. run your own, use an open relay, or pay for one from folks you trust.

What problem is that a solution to? Is there a problem with someone owning it, in that case: what?

> Is there a problem with someone owning it

Yes

> what?

They can decide you can't use it anymore

They can decide to charge more for it

They can arbitrarily take features out from under you or change how it works

They can read and/or sell/give away/accidentally get exploited and lose your data

They can prevent your extracting your data to move away from them

They can prevent you building or integrating other tools

They control how you can modify or configure the software

[I work for Slack, opinions very much my own] Having agents see everything you and your colleagues see is cool. The challenge comes when you want to make certain things private to certain people. In that world you don’t want multiplayer agents leaking data, so you end up having to write and maintain complex rulesets about what specific resources agents have access to. Single-player agents, on the other hand, are much…

I'm confused are against the idea of private groups at all or just that you can't change the visibility settings later on?

Now when I see new software projects I just think of how much of them are made with agents and the unreliability/easy abandonment that comes with it. Ten years ago this product would have been of a known quality. Not saying anything about buzz specifically.

I find this thought process somewhat faulty given that the vast majority of software ends up in that spot regardless. Hard to take this as that big a deal when Google literally launched a product along similar social themes named "Google Buzz" which lasted all of like 16 months in 2010, well before agents and llms. Either the project will find a fit, or it won't - and code quality doesn't have all that much to do wit…

Argument similar to: people still get hurt riding a skate without a helmet, why do I need it anyway?

No one is going to churn Slack for this just because it is "Agent First". Slack is more than good enough to tag Agents and will fill in the missing pieces slowly

I would pay money to not have to use slack

Disclaimer: I'm not working for them, just FYI.

Seems to be an raft.build competitor but open source.

BTW, from my very own opinion, IM is a great place for agents to chat, but not a good place for get work done. Something more comprehensive like Linear should be work better. Communication is a key stone but not all for the agents.

so your agents can't access any private information in public channels? Not very useful. Still probably better than Claude's new bot which requires a service account per channel!

Hang on a second. You think accessing private information in a public channel is a good idea? If a tool is authenticated as personal then it can be only accessed under personal context - i.e. privately. Now if the author of the agent wants to add tools authenticated with shared secrets that is something should be considered in the threat model. In other words: - reading my personal emails in a public setting - not ok…

> not ok - reading the agents shared inbox in a public setting - probably ok depending on the threat model

This is never secure. Some SAAS apps have automatic enrollment into company/teams based on email domain. So you can sign up with the email address of the agent and then ask for any 2fa code or other emails.
