# `mix cairnloop.doctor`
[🔗](https://github.com/szTheory/cairnloop/blob/main/lib/mix/tasks/cairnloop.doctor.ex#L1)

Diagnoses your host application's Cairnloop wiring and prints calm, reason-forward findings.

It inspects your router and `:cairnloop` config to catch the "compiles but isn't wired"
problems that are easy to miss: a dashboard or `/health` route that was never mounted, a
`/metrics` endpoint that will 501 because the optional Prometheus dependency is absent, or an
audit log that will render empty because no auditor is configured.

## Usage

    # Infer your router (<App>Web.Router):
    mix cairnloop.doctor

    # Name the router explicitly (umbrellas / non-standard names):
    mix cairnloop.doctor MyAppWeb.Router

    # Treat warnings as failures (CI):
    mix cairnloop.doctor --strict

## Exit codes

- `0` — no blocking issues (warnings allowed unless `--strict`).
- `1` — at least one blocking issue (or any warning under `--strict`).
