# `mix emily.doctor`
[🔗](https://github.com/ausimian/emily/blob/1.0.0/lib/mix/tasks/emily.doctor.ex#L1)

Diagnose the local Emily runtime installation.

The task checks the host platform, active MLX variant, required
`priv/` artifacts, NIF loadability, and a tiny Emily backend smoke
test. Checks short-circuit: when a prerequisite fails, dependent
checks are reported as `[skip]` instead of running and producing
cascading noise.

## Flags

    --help        Print this help text and exit.
    --variant     Override the active variant (`aot` or `jit`) for
                  this run, e.g. `--variant jit`. Does not mutate
                  config — used to ask "would this host satisfy
                  :jit?".

# `check`
