Doctor

Doctor turns delivery-system drift into a read-only health table with an owner and a routed next action.

What it adds

The skill checks harness parity, plugin and skill state, marketplaces, routing policy, credential presence, fleet readiness, store state, and runtime health.

How it works

Each row names the observed condition, evidence source, and owning fix surface. A follow-up fix routes through the skill that owns the affected surface, then the row is checked again.

Scope

Doctor diagnoses and reports. Mutation belongs to the approved owning workflow.

Source

Ships in the railyard plugin. Source: plugins/railyard/skills/doctor/SKILL.md.

Proof point

The doctor source defines read-only diagnostics, explicit credential presence checks, and re-checks after a routed fix.

Next: read setup or inspect fleet readiness.
