pi doctor Check Pi preconditions without changing the installation.
pi test Run the temporary Pi/core smoke checks.
pi check Alias for pi test.
pi configure Apply non-secret provider/model/thinking defaults to core (credentials stay in PI_AUTH_FILE).
pi update Rebuild or pull a pinned Pi image (--source build|pull and --yes required).
pi configure [--provider P --model M --thinking low|medium|high]
Select closed backend defaults interactively on a TTY; all flags are required otherwise.
pi update --version V --source build --yes [--drain]
Rebuild a pinned Pi version and recreate only core.
pi update --version V --source pull --image IMAGE@sha256:DIGEST --yes [--drain]
Pull an immutable candidate and recreate only core.
pi rollback --yes Restore the image recorded by the latest Pi update.
pi logs Show the latest sanitized core logs.
pi maintenance status
Show the durable core admission-gate state.
pi maintenance recover --yes
Verify a terminal installation, remove stale lifecycle files, and clear maintenance.
