    "incantation": "If the repository has a Railway IaC file and is linked to the target project and environment, run `railway config plan` to preview changes, `railway config apply` to apply them after confirmation, or `railway config current` to inspect current configuration. The official documentation describes `plan` and `apply`, but I could not verify `config current` there.",

    "gotchas": [
      "Version: v5.42.0",
      "Prerequisite: Install the Railway CLI, authenticate with `railway login`, and link the directory to the target project and environment with `railway link`.",
      "Prerequisite: For `plan` and `apply`, the CLI searches the current directory and parent directories for `.railway/railway.ts`, `.railway/railway.py`, or `.railway/railway.go`.",
      "The preserved runner behavior applies when `--runner`, `RAILWAY_IAC_TS_BIN`, or `RAILWAY_IAC_ENGINE=ts` is set.",
      "The release reports TypeScript and Python file evaluation coverage; it does not state Go evaluation coverage."
