  "how": {
    "incantation": "When a service-scoped command targets a project without a linked working directory, include `--project <PROJECT_ID>` and `--environment <ENVIRONMENT>`; without `--project`, Railway uses linked project, environment, and service fallbacks. For `domain`, use `--project` without `-p`, which selects the port.",
    "examples": [
      "railway logs --project <PROJECT_ID> --environment <ENVIRONMENT>",
      "railway variable set <KEY>=<VALUE> --project <PROJECT_ID> --environment <ENVIRONMENT>",
      "railway domain --project <PROJECT_ID> --environment <ENVIRONMENT>"
    ],
    "gotchas": [
      "Version: v4.57.4",
      "--project <PROJECT_ID>: Project to use; defaults to the linked project when omitted. Pair with `--environment` when specifying a project.",
      "--environment <ENVIRONMENT> (required): Environment to use with `--project`; the CLI docs say this flag is required when targeting a specific project.",
      "-s, --service <SERVICE>: Service to target; defaults to the linked service. Service name or ID is accepted.",
      "-p, --port <PORT>: Port to connect to a domain when creating one; `domain` uses `--project` without a short flag.",
      "<KEY>=<VALUE> (required): Variable assignment for `railway variable set`; repeat assignments to set multiple variables.",
      "Commands that accept `--project` require `--environment` to avoid ambiguous cross-project environment resolution.",
      "`domain` uses `--project` without a short flag because `-p` is already used for `--port`.",
      "Single-service fallback behavior is preserved for commands that can infer the target service."
    ]
  },
  "why_it_matters": "Run a service-scoped Railway CLI command against a project without linking the working directory first.",
  "before": "Use the linked project, environment, and service context; commands requiring project targeting could also be run after linking the working directory.",
