    "incantation": "When reviewing a Railway deployment, inspect metrics for the linked service (last hour by default) or select a service and environment; use the documented filters, time range, or output mode for the needed detail.",

      "railway metrics --service <service> --environment <environment> --since 6h --json",
      "railway metrics --http --method POST --path /api/users",

      "Version: v4.45.0",
      "--service <service>: Select service by name or ID; defaults to linked service; conflicts with --all.",
      "--all: Show metrics for every service in the project; conflicts with --raw.",
      "--environment <environment>: Select environment by name or ID; defaults to linked environment.",
      "--since <time>: Window start; relative value (1h, 6h, 1d, 7d) or ISO 8601; defaults to 1h.",
      "--until <time>: Window end, using same formats as --since; defaults to now; conflicts with --watch.",
      "--cpu: Show CPU metrics only, unless combined with other metric group filters.",
      "--memory: Show memory metrics only, unless combined with other metric group filters.",
      "--network: Show public network traffic only, unless combined with other metric group filters.",
      "--volume: Show volume/disk metrics only, unless combined with other metric group filters.",
      "--http: Show HTTP metrics only, unless combined with other metric group filters.",
      "--method <method>: Filter HTTP metrics by request method; requires --http; method value is case-insensitive enum.",
      "--path <path>: Filter HTTP metrics by request path; requires --http.",
      "--json: Output in JSON format; conflicts with --watch.",
      "--raw: Output raw time-series data points instead of summaries; conflicts with --all and --watch.",
      "--watch: Continuously refresh metrics in a live TUI dashboard; conflicts with --json, --raw, and --until.",
      "Prerequisite: Install Railway CLI and authenticate with `railway login`; link a project/environment for the command context. Official CLI docs list installation and authentication steps.",
      "Prerequisite: HTTP filters `--method` and `--path` require `--http`; `--watch` supports only documented time ranges for `--since`."
