This man is on fire.

[Matt Van Horn @mvanhorn]

Introducing the Printing Press, a CLI-factory and a CLI-library. Built with @trevin. 🏭🖨📚

Most APIs suck for agents. Most MCPs suck for agents. Most official CLIs suck for agents. They waste tokens and time. @steipete started making his own because of this.

📚 A Library of agent-native CLIs you install today (Linear, ESPN, Flight GOAT (Google Flights + Kayak nonstop), Contact Goat (LinkedIn + Happenstance + Deepline more) +30+ more)
🏭 A factory that prints new ones for any service - just type /printing-press <product name>

CLIs are fast, local, SQLite-backed. Work in Claude Code, Codex, OpenClaw, Hermes.

Soon we’ll combine (a) the speed of execution seen in Taalas with (b) the duration of execution seen via METR.

And get days of work done in seconds.

[Fauna Robotics @faunarobotics]

Meet Sprout.

Today, we’re releasing a new kind of robotics platform. One designed to move out of the lab and into the real world, closer to the people who will shape what robots become next. [1/4]
