## three ways in.

all three are equally welcome. pick the one that fits and the form starts there.

### a role

engineering or architecture work where agents do real work: harnesses, context and memory, workflows that need to be deterministic. AI labs included.

### a consulting project

you have agents and real systems. i help design the context, the tools and the boundaries around them, and get your team ready to work with agents.

### 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.

### 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.
