[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 more straightforward — they act on a single user’s behalf, and then the challenge is ensuring the single-player agent cannot exfiltrate private data into a shared space unless the user specifically permits it.

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.

If you wrote it on your company's slack space, it is not really private to the company. Everytime I have a "private" conversation in Slack I have the understanding that the information could be shared. Even now there is a share button not for the whole conversation but yes for individual messages

My understanding of what they were saying Buzz is is that agents are "1st class" users in their own right, rather than being an app integration.

If you have a user called Claude, then you just apply ACL as normal & you don't care if they're human or bot, right?

jaggederest 45 minutes ago||
The issue is when users interact with claude, what can they see? If the AI can see super-secret-payroll-details.md - is it allowed to discuss that with any user? is there some sort of internal ACL within claude that asks pretty please don't tell everyone they're underpaid?

That's why multiuser agents can be an issue.

The other way to do this, is to have claude installed for everyone, and any user's chat with claude uses their personal permissions via something like oauth delegation or AWS IAM role kinda things. But that, again, is complicated ACL logic living through the delegation of roles and access

_pdp_ 1 hour ago|||
I agree with what you are saying but this is not how we solved the issue with who can access what.

In our cloud harness we have the notion of shared and private secrets. When something is authenticated with a shared secret it is basically something that can be used in a public setting. If something is private then it can be only accessed via trusted channel. It works for slack, telegram, etc.

In fact, our slack agents are very strong this department and it is guaranteed there is zero leak of private information.

And if someone gets access to a channel that they shouldn't?

The best norms around slack channels is to have most channels be public, but have norms where not everyone is in every channel.

hibikir 1 hour ago|||
I have lived in organizations where under 1% of messages were made on public channels. The experience of finding information in slack, or even knowing if there's a private channel where all of this is discussed, but where nobody invited you to, is not one I wish on anyone.
_pdp_ 1 hour ago|||
No channel will disclose private information. The only way to get that to work is to DM the agent directly or to use slash commands which are ephemeral / private.
datadrivenangel 1 hour ago||
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!

_pdp_ 1 hour ago||
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 - reading the agents shared inbox in a public setting - probably ok depending on the threat model

Why wouldn't you simply use the group chat ID (+more) to key the conversations on?

Because there’s an unlimited number of groups with different combinations of memberships. If I am in group A but not group B and an agent is in both, what is it allowed to share with me?
ahf8Aithaex7Nai 1 hour ago||
I'd like to see this problem solved in such a way that your group memberships are transitively applied to your access to agents. In other words: you shouldn’t be allowed to talk to an agent at all if, at a given point in time, that agent is or was in a group that you are not or were not in at that time. Does that make sense? I don’t know how practical this restriction is, but letting the AI manage such permissions on its own seems reckless to me.

These kinds of rules never survive real world tests. For example if I create a private group just for myself and auto invite every agent in the company into it, does that mean no one can now use any of them?

Maybe this is naive or startup-brained of me: I understand not wanting HR-related things to be potentially exposed by a misaligned agent, but when it comes purely to the building of software I personally do not care at all who can read the code/discussions & engage with the process.

all ingested data and all derivations of that data can link to source channel and associated ACL that syncs with the source. then search/reads/etc just join on and respect the ACL. not that complicated to manage for things like slack, meetings, etc.

The product seems to use the same 'scoping' mechanism that humans would use, so you can give agents access to whatever 'channels' you want.

The issue seems to be that they 'invented' an auth and permission protocol instead of delegating to something existing, it would be as if they thought their idea of permissions were novel.

It’s kinda interesting seeing what, IIRC, was originally a subreddit name which spawned from an AskReddit thread, is now a common marketing phrase in the tech world.

Similar to the sub itself, it’s now just shorthand for “describe using the first principles the expected audience should understand.”

I imagine a lot of people in the industry also fondly remember the 2010s reddit experience.

Not sure how long the subreddit has existed but I always assumed it was inspired by the episode of The Office where Michael asks Oscar to explain what a surplus is like he's 5. The broader usage on social media and the ELI5 shorthand are definitely the result of the subreddit though.

Disclaimer that I used to work at Slack

I love that we're challenging the status quo in chat. It feels like we've settled into an eternal September of sorts. I am somewhat bearish that Slack and Teams will survive, or rise to, the agent era.

That said, I'm curious whether NOSTR is really the protocol for this. For some really large corporations you're looking at a lot of clients (and their shadows like cellphones, local agents etc) as well as a lot of (likely) team-based agents.

The identity architecture makes sense for centrally hosted agents. Users also probably have their own personal agents as well. Do those just reuse user credentials or are they differentiated in some way? I couldn't tell.

I also am curious whether git really needs to be a dependency here. Like, maybe for Block it does, but it introduces a lot of complexity that I feel could be exported to merging VCS Host events to the Buzz event log.

I'm also curious what challenges will arise as new capabilities emerge. For instance, both Sol and Claude can now render native components in my chat window which is a massive leg up in terms of firming up a design change.

Rust is also a choice. I'm curious what alternatives the team considered and how they landed on Rust.

I think a happy medium like signal would be much better, slack is an immovable part of much of the (white-collar) business relationship world now but it'd be nice if there were assurances of secrecy and security in communication as 24/7 cyberattacks rather than a company whose security is based solely on promises rather than zero-knowledge systems. Signal has had far and away the best cross-platform messaging experience of any client I've used in friend groups but moving to a slack-like system alongside what exists now would be much appreciated to the noisy channel approach.

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 with it existing in 2 years (some - but not as much as engineers want to believe).

Bots in team chat is not a bad idea. I've been experimenting with that for a few months.

We started with Slack. This kind of works but dialing in the gazillion of permissions needed to end up with something that works is a bit painful. And you have to do this over and over again for each new bot.

So, we started experimenting with self hosted alternatives. First we tried Matrix. It's nice but a bit too strict on end to end encryption which gets in the way if you actually want to share information with bots. So, a few weeks ago we switched to Zulip. That's pretty straightforward to setup as well. It's very easy to create bot users with both and create some automations. We did some with Openclaw and I ended up replacing those with something coded around the haystack framework, which is a bit less of a messy basket case than Openclaw.

And as I discovered after I installed it, the Zulip leadership actually just got hired by Anthropic. It seems Jack Dorsey beat them to market making some announcements but I imagine that Anthropic might have very similar plans.

IMHO team level use cases for agents actually make a lot of sense. Companies are run by groups of people and the larger those groups the more team overhead you get. Perfect for optimizing with AI. And if you have people doing a lot of stuff with AI, that only adds to the need for them to communicate what they are doing and coordinating with others. Doing that out in the open in some shared channel makes a lot of sense. And having some shared team guard rails also makes sense. And if you think about more complex processes with handoffs between people (and possibly some agents), a team chat is a good place to do those as well.

Slack exists largely because IRC was insufficient. It didn't natively support channel history, search, etc.

For AI agents to flourish, Slack has to either truly open its network with a protocol or eventually be replaced.

I'd like to see Slack embrace an AT protocol-based chat system, which then apps like Buzz could implement. Then users could log in with domain handles like @yourname.com, and agents could use handles like @agent1.yourname.com, all under their complete control.

Why is it Slack's responsibility to help agents flourish?

I ask about Slack here because it's pertinent, but I've both seen and experienced firsthand this inversion across the industry where we must adapt our workflows for AI.

> Why is it Slack's responsibility to help agents flourish?

Technically, because if the world moves to AI-driven tools and Slack is not cooperating, it will no longer serve the world and will be left behind.

> Isn't a tool supposed to work for you

If you want AI integration in your chat and Slack is not helping make it happen, then Slack is not working for you.

On the other hand, constantly chasing the latest fad can be a useless drain of resources and (worse yet) attention. In this context, AI is by now most likely not a fad, but the ways to interoperate with it can be: mcp, cli, agent, tag, ... And the same goes for users, reinventing their processes and practices 5 times per year.

_verandaguy 2 hours ago||
I think this is missing my implied point. Is this desire for AI integration actually coming from most people? Or is it a handful of decision makers who aren't thinking about the technology critically for one reason or another (either due to lack of information/understanding, or a financial stake)?

AI is still seen very negatively in opinion polls across multiple countries, and anecdotally, tools which were often obnoxious to use before AI are now much more so, at least to my flesh-and-blood self. It really seems like we're making things worse for ourselves just to help support this would-be self-fulfilling prophecy.

Just my two-cents as a very much boots-on-the-ground infrastructure engineer. We use LLMs heavily on my team -- to write code and review PRs. Our harnesses and guardrails are very very good so we get extremely high-quality output out of most models.

But getting the humans and agents to talk together is really fragmented right now. It's annoying that the agent with the context in my locally-installed Cursor can't really participate in a Slack conversation about a PR that 'it' principally authored (and which I've signed off on).

This is a real communication problem that we face every day, and eventually someone will solve it well and I will ask our leadership to give them a lot of money.

> Is this desire for AI integration actually coming from most people?

Ahhh I see. That's going to change a lot across companies, teams and individuals. My particular bubble is full of actual workers looking for ways to apply it and trying things to see what sticks, so that interpretation did not land in my head. If anything, decision makers around me are being encouraging, but cautious and throttling experiments and requests for access/connection/etc, and damn well they should because they are actually accountable for mishaps.

calebkaiser 1 hour ago||||
I'm sympathetic to this POV. I think specifically in the case of Slack, it's not their responsibility in a cosmic sense, but it is in line with the direction and general promise they've been making to customers since forever.

A major part of Slack's go-to-market strategy for as long as I can remember has been pushing Slack as more than a interface for talking with teammates, but as a unified interface for generally piloting your business. Slack has heavily pushed ideas like "SlackOps", they've had Slackbot in the product forever, and they've always prioritized and sold integrations designed to let you build your business workflows in Slack. They even updated Slackbot to go from "that chatbot you DM to set reminders" to "Your AI teammate in Slack": https://slack.com/features/slackbot

So adapting to agents is in keeping with what Slack promises its users. I know that a lot of people don't want more AI features in apps that don't need them (i fall into this camp despite working in ML myself and using LLMs all day). I just think that in the case of Slack, their most passionate power-users are also the sort of people who do really want AI features.

Notion is probably a good companion here. It is similarly a really primitive utility--text editing--that has marketed itself as a sort of central interface for running your company. I know plenty of people, especially outside of engineering, for whom Notion is essentially their browser for work. And it's probably not a coincidence that the Notion + Slack are the two normal office software companies I can think of who've most heavily adopted and marketed AI features.

There's many new and existing companies right now that are growing fast based on the promise of doing "x but with AI". This starts from customer support tools, coding agents, code review platforms and they are definitely "capturing a bag" there.

I'm not blind to the issues with AI, but Slack ignoring it (Apart from their enterprise AI search they are pushing) and having the bots interact on the platform right now (Basically spewing a lot of messages in threads with all their "thinking" and not a more native integration) is not going to help them.

There basically haven't been any new features on their bot / app platform for a long time now.

Nostr gives you and your agents a durable, portable identity across communities/relays/workspaces.

You can also independently verify that the messages you're reading came from the person/agent who sent them, even if the server/relay operator is broken or trying to trick you.

This can be important in environments that live outside of enterprise auth walled gardens.
