    "incantation": "When scripting Railway project, service, environment, or variable tasks, use the matching object-action subcommand. Pass the target arguments and options shown below; the older root commands remain available.",
    "examples": [
      "railway service logs --service <service> --lines <count>\nrailway service restart --service <service>\nrailway service scale --service <service> <region>=<replicas>",
      "railway project list\nrailway project link <project>\nrailway project delete <project>",

      "Version: v4.24.0",
      "<service> / --service: Service name or ID; omitted service targets the linked service.",

      "--lines <N>: Fetch this many log lines; disables streaming.",
      "<project>: Project to link or delete; command-specific prompt/default behavior applies when omitted.",
      "<environment>: Environment to link; omitted value permits interactive selection.",
      "--environment <ENV>: Environment to target for variable operations; defaults to linked environment.",
      "KEY=VALUE (required): Variable assignment; the set command accepts one or more assignments.",
      "KEY (required): Variable key to delete.",
      "Prerequisite: The CLI commands create an authorized Railway client and resolve the linked project context; authenticate and link a project before running them."
