    "incantation": "When inspecting flags for a linked project, run `vercel flags datafile` to summarize variants, rule and target counts, and environment reuse. Choose an environment with `--environment`, use `--sdk-key` for SDK key authentication, or add `--json` for JSON output.",
    "examples": [
      "vercel flags datafile --environment <development|preview|production> --json",
      "vercel flags datafile --sdk-key"
    ],
    "gotchas": [
      "Version: 65.1.0",
      "--environment: Selects development, preview, or production.",
      "--sdk-key: Uses an SDK key for authentication; the key is read from stdin or a masked prompt.",
      "--json: Outputs a JSON document.",
      "Prerequisite: Requires a linked project. Feature is listed in Vercel CLI 65.1.0 release notes.",
      "The summary covers the variants each flag can serve, its rule and target counts, and the environment it reuses.",
      "Preview and production use the CLI user token.",
      "Development requests a project OIDC token and uses the user token if no OIDC token is available.",
      "SDK key authentication reads from stdin or a masked prompt so the key never appears in argv."
