+  # The Gemini CLI Extension format.
+  # See https://github.com/google-gemini/gemini-cli/blob/main/docs/extension-releasing.md#platform-specific-archives.
+  # We'll use platform and architecture specific archive names, which must look like:
+  #
+  # {platform}.{arch}.{name}.{extension}
+  #
+  # Where the fields are:
+  #
+  # - {name}: The name of your extension.
+  # - {platform}: The operating system. Supported values are:
+  # -     darwin (macOS)
+  # -     linux
+  # -     win32 (Windows)
+  # - {arch}: The architecture. Supported values are:
+  # -     x64
+  # -     arm64
+  # - {extension}: The file extension of the archive (e.g., .tar.gz or .zip).
+  #
+  # Examples:
+  # - darwin.arm64.{project}.tar.gz (specific to Apple Silicon Macs)
+  # - linux.x64.{project}.tar.gz
