  "how": {
    "incantation": "When managing Railway service or custom domains from the CLI, use `railway domain` subcommands to list, inspect, update, retry certificates, or delete. Create a generated service domain or custom domain with `railway domain [DOMAIN]`, adding `--port` when needed; for custom-domain creation with CLI OAuth, use the documented create flow without a separate availability preflight.",
    "examples": [
      "railway domain list --service <service> --json",
      "railway domain status <domain-or-id> --service <service> --json\nrailway domain update <domain-or-id> --port <port> --service <service>\nrailway domain certificate retry <domain-or-id> --service <service>\nrailway domain delete <domain-or-id> --service <service> --yes",

    "gotchas": [
      "Version: v5.14.0",
      "DOMAIN / DOMAIN_OR_ID: Creation accepts an optional custom domain; status, update, certificate retry, and delete require a domain name, URL, or domain ID.",
      "--port: Port to connect to on creation; target port for domain update. Validated as a port value.",
      "--service: Service whose domains to manage; if omitted, uses the resolved linked service context.",
      "--environment: Environment to use; defaults to the linked environment.",
      "--project: Project ID to use; defaults to the linked project.",
      "--domain <DOMAIN>: On update, rename a Railway-provided service domain using a full service domain or host label; custom domains cannot be renamed.",
      "--yes / -y: Skip the delete confirmation dialog.",
      "--json: Output in JSON format.",
      "Service-domain target ports can be updated and service domains can be renamed.",
      "Custom-domain target ports can be updated.",
      "Legacy `railway domain --json` output shapes are preserved.",
      "The change adds local MCP parity for create, list, status, update, certificate retry, and delete domain workflows."
