AI isn’t magic. It’s a supercharger for engineers who learn to drive it.
I’m Zach Koncir. I build open source tools that keep engineers at the centre of AI, and I help people and teams get past the hard part: learning to use it well.
Open source
pi packages
Extensions for pi, the terminal coding agent I work in every day.
pi-halo
v0.3.0
A workbench for pi. Build and Plan modes, a sidebar and home screen, a git diff view, and git commands that draft commit messages and pull requests.
pi-domain
v0.2.0
Persistent memory for pi. The agent saves decisions, preferences and gotchas as it works, and the next session starts with a short index of them. Everything stays in one SQLite file on your machine.
pi-containment
In design
A guard layer for pi tool calls. One place to decide which calls the agent may make, which need your approval, and which are never allowed.
Other projects
Kiln
In design
An agent-driven CI/CD system built on pi-durable. Deterministic pipelines decide pass or fail; agents read failures, propose fixes, judge release risk and watch rollouts around them.
