hanzo experiment listEvery command takes --json for the raw response and --help for its own flags. Sign in once with hanzo auth login; the commands below use that session, and the org they act in is the one it carries.
| Command | What it does |
|---|---|
hanzo experiment analyze <id> | Per-variant conversion, lift and statistical significance against the control arm. |
hanzo experiment assign <id> --subject <subject> | The variant one subject is bucketed into, and the payload that variant carries. |
hanzo experiment create --id <id> --metric-event <metricEvent> --variants '[{"control":false,"key":"<key>","payload":"<payload>","weight":0}]' | Registers a controlled experiment AND puts its assignment flag live, in that order, so the arms start bucketing subjects the moment this returns 201 — the flag is created active at 100% rollout, with each variant weighted as declared. |
hanzo experiment decide <id> --winner <winner> | Promotes one variant to the whole rollout and records who decided. |
hanzo experiment get <id> | One experiment's definition and lifecycle: variants, weights, control arm, status and winner. |
hanzo experiment health | Whether the experiments subsystem is mounted and serving in this process. |
hanzo experiment list | Every experiment in the caller's org, with its variants, status and decision, ordered by project then id. |
