hey everyone! the @roost.tools Osprey working group is meeting today at 10:30am PT / 1:30pm PT / 7:30pm CET / 12am IST @cassidyjames.com is working on other ways to make our calendar more accessible! agenda is light, add to it here: github.com/roostorg/osp... discord.gg/UzKGh66Gb?ev...

Next week on Friday I'm doing my first ever office hours! If you have questions for this is your chance! atmo.rsvp/p/thisismiss...

If you see this, I implore you to post a picture from whatever device you're using with no explanation.

I’m working to standardize how we do community working groups/office hours at @roost.tools, including the nitty gritty like: • scheduling/reminders • agenda sharing • notetaking • noting/following up on action items Community peeps, what are YOUR tips? What tools are clutch? What should we avoid?

The @roost.tools Model Community office hours start in about 10 mins! It’s a community of people using ML models, LLMs, classifiers, or other AI-adjacent tech sharing best practices and trying to open up the ecosystem a bit more. If you’re involved in T&S, come join us, even if just to lurk!

I'd love to see some of the wonderful atproto peeps I met at AtmosphereConf! @roost.tools is open source, and you know what that means: we can just do things. Come learn, share thoughts, and meet others who are shaping how models can be (and are being!) used for good in trust and safety contexts.

Patrick Farry wrote about our Osprey project for @infoq.com! www.infoq.com/news/2026/03... "The combination of the Rust coordinator for traffic shaping and the scalable Python workers provides a resilient system for continuous event evaluation."

@roost.tools is hosting our Model Community office hours tomorrow at 1230pm ET! Feel free to add to the agenda. Learn how T&S peers are using AI for safety workflows, ask for support in implementing open safety models, and how you can contribute to ongoing projects github.com/roostorg/mod...

The talk by @roost.tools team was really informative and high energy; they're doing such good work over there and I now really want to play with Coop a bunch

a successful last dinner with @graham.systems @gov.glados.computer @meri.garden @ngerakines.me @laurenshof.online @raedisch.net @essentialrandom.bsky.social @vicwalker.dev.br @riccardo.bsky.social @trezy.codes thanks @quillmatiq.com for organizing!

thanks for a great week @bmann.ca @knowtheory.net @ngerakines.me @lucca.northsky.team and the rest of the conference producers and volunteers! it was so great meeting everyone in person and talking about how @roost.tools can help everyone building on AT protocol ❤️

As promised, here are some links from our #ATmosphereConf talk by @cassidyjames.com and @julietshen.bsky.social! First, here are the slides; we ran over time and so didn't get to share the last couple of slides with you all, but they're important. :) docs.google.com/presentation...

Coop features:

What is Coop?

Roost is open source!

Four Functional Quadrants for Trust & Safety Tools: Detection, Investigation, Review & Enforcement (DIRE). Paper link: papers.ssrn.com/sol3/papers....

@julietshen.bsky.social and @cassidyjames.com talking about @roost.tools ! #ATmosphereConf

It’s @roost.tools! Love hearing @julietshen.bsky.social and @cassidyjames.com talk about this space. #AtmosphereConf

Thanks for the shoutout @sebastian.eurosky.social @eurosky.social ! ROOST's projects are self-hostable, making it so any project that wants a flexible review tool (coop) or sophisticated rules engine (osprey) can run it on their own infrastructure. Private data that stays in your systems.

say hello to the ROOST team if you're at #atmosphereconf @julietshen.bsky.social @cassidyjames.com

Atmosphere conference officially starts tomorrow! it's been great talking to people about @roost.tools and even overhearing magical hallway conversions about ROOST and the tools that we're building. @cassidyjames.com and I will be around all weekend, so come find us to talk safety and moderation 🐓

If you're an open source lover and infrastructure person (aka were roaming the halls of #KubeCon or will find all the storage and data pipeline talks at #ATmosphereConf), @roost.tools is looking for you! We've got fully remote, Infrastructure Engineering roles now open: roost.tools/infrastructu...

I've arrived in Vancouver for #ATmosphereConf! Looking forward to meeting a bunch of folks tomorrow to learn a ton and talk about the cool stuff we’re doing at @roost.tools 😁 And shout out to @vvill.dev who helped me figure out how to get into my room when we ran into each other at the same rental!

roost is an important company. working here means working on actual online safety.

We are still hiring, with a more scoped job description now. We are a global, remote organization so let us know if you're interested and have relevant experience! roost.tools/infrastructu...

it's been amazing for us too, @matrix.org ❤️ Congratulations on all the impact! matrix.org/blog/2026/03...

I am in the nest #atmosphereconf

join @julietshen.bsky.social in room 2311 for an Unconference session on trust and safety at 3:30! #ATmosphereconf

thunderbirds probably roost, right?

RSVP to our talk! atmo.rsvp/p/julietshen...

thank you everyone for coming out to dinner! something that started as "let's make a reservation for 3, I'm sure someone else will show up" turned into more than 20 ATproto explorers hanging out. An awesome start to @atmosphereconf.org !

@aaron.bsky.team shouting out how great using Osprey is for investigating! Go @roost.tools @julietshen.bsky.social #opensource #tssummit #trustandsafety

Who’s going to #ATmosphereConf? 👀 I’ll be there to talk to people about open source trust and safety! If you’re building something cool (or just want to chat), let’s meet up.

if you haven't gotten your ticket yet, you can use our link for $50 off! 🪿

Are you headed to @atmosphereconf.org? Our Head of Product @julietshen.bsky.social and our Community Manager @cassidyjames.com will be goosing off this week and into the weekend! Catch ROOST's talk on Coop, our OSS review tool, on Sunday: atmosphereconf.org/event/0Qq9NlZ #ATmosphereConf

We've released v0.1 of Coop which mostly focuses on security, stability, and infra improvements. There are a few new things like a signal integration with Zentropi, improvements to reports sent to NCMEC, and scaffolding for config-based integrations! github.com/roostorg/coo...

We’re proud to be a media sponsor of ATmosphereConf 2026! The global @atprotocol.dev conference is coming to Vancouver, BC — March 26–29 at UBC campus. Two days of workshops, two days of talks & community, plus a full remote track.

We released Coop v0 a month ago, and we have heard a lot of feedback about what would make it easier to use, explore, adopt, contribute to, etc. Check out our Coop simplification plan; we welcome any and all ideas and suggestions! github.com/roostorg/coo...

Online safety shouldn't be a competitive advantage. It should be a shared foundation. That's why ROOST exists. 🧵

We hear a lot of, "I really just need..." when we ask developers about their platform safety challenges. While some are platform-specific (so won't be shared w/o permission), so many are universal requests. We started a "safety tools wishlist" for more ideas and upvotes: github.com/orgs/roostor...

A lot of good conversations at #GDC2026 about what game developers are struggling with in making safe play experiences and protecting their users ❤️

We're on the ground at GDC Festival of Gaming this year! Let us know if you're there, too, and come say hi to our COO @annebdh.bsky.social. And if you get a hold of one of our special, limited postcards, take a photo and share it with us!

Content moderation tooling presents an entirely different collection of user interface and user experience challenges unlike any other software. Design isn't for flair or optimising engagement but is instead about protecting. I wrote about some considerations: vale.rocks/posts/modera... #UI #UX

I only understand half of what osprey is, and it's one of the most impressive things I've seen recently. I truly think this is a game changer for moderating content on the atmosphere and is such an amazing thing to have open sourced

@discord.com open sourced their internal T&S rules engine with @roost.tools! Osprey handles ~400 million actions per day in production at Discord. If you run a Discord-sized (or smaller!) platform, you can just… use their rules engine because it’s open source. #OpenSource #TrustAndSafety #Discord

Open sourcing Osprey was an adventure! @discord.com is now powered by the open source community version of Osprey. Read about how Osprey works and what makes a rules engine for fighting abuse powerful: discord.com/blog/osprey-...

@dwillner.bsky.social and @samidh.bsky.social have released open models for online safety, pushed transparency with their model cards, and made it easier for teams to kickstart their safety work with their policy labeler library. We're excited that they're now integrated with our review tool, Coop!

@dwillner.bsky.social and I have spent years watching T&S teams rebuild the same infrastructure from scratch. This is what it looks like when open tools actually work together instead. Really proud of this one and appreciative of @roost.tools's leadership! Details: blog.zentropi.ai/zentropi-now...

Zentropi is now integrated into Coop, @roost.tools's open source moderation platform. You can write a content policy in plain English on Zentropi, plug it into Coop as a signal, and have a moderation pipeline running in minutes.

Every trust & safety team faces the same impossible choices: Do you optimize for flexibility or performance? Accessibility or expressiveness? Speed or confidence?
