Radian is a coding agent shipped as one Rust binary. It starts with no runtime to boot and spends context on the lines a task needs, and its headless command prints every step as a JSON line and exits with a code that says how it ended.

The headless command prints every step as a JSON line and exits with a code that says how it ended, so a task can be driven from a script or a CI job.
Radian is one Rust binary with no runtime to boot, installed with brew install hisea/tap/radian.
The terminal session shows the agent thinking, running shell commands, reading files and patching code, with timings and exit codes for each step.
