  • what does an agentic systems architect do?

    i design the systems around AI agents: what they know when a session starts, which tools they can use, where the walls are, and how anyone can tell the work is done. the models come from the labs; the system around them is my part.

    how i work

  • what is PM CLI?

    open-source, git-native project management for people and coding agents. goals, decisions, tasks and evidence live as plain files next to the code, so a fresh session can pick up the thread. i started it in february 2026 and maintain it; it’s MIT-licensed and on npm as @unbrained/pm-cli.
