Working code, public. The most verifiable thing on this site: all of it is mine or my team's, and the reasoning is in the repo. Each one exists because something was missing and the gap was worth closing in the open. The older ones are unmaintained, marked as such, with live signals straight from GitHub.
# why I built it
CLIs rot when the help text drifts from the flags. Odin makes the documentation a product of the definition, so it can't lie about what the command actually does.

Crystal had the speed of compiled code with the feel of Ruby, but no expressive way to define a CLI. Admiral is the DSL I wanted to exist: declarative commands, flags, and args that read like intent.

We ran it in production at both GigSmart and CommercialTribe to make Kubernetes deploys repeatable and fast: manifests as templated config, not copy-pasted YAML drifting per environment. The deploy path is a product; this was part of building that track.

Async composition without callback soup. Borrowed the mental model engineers already carry from JS so concurrent Crystal code stays readable.

Agent tooling spreads fast and unevenly. Han is the opinionated layer: plugins vetted against how good engineers actually work, so the volume layer inherits judgment instead of replacing it.

The connective tissue that makes the rest move faster. Boring on purpose. The part of the toolchain that earns its keep by getting out of the way.
