+# Gemini API Replay Script
+# -----------------------------------------------------------------------------
+# Purpose:
+#   This script is used to replay a Gemini API request using a raw JSON payload.
+#   It is particularly useful for debugging the exact requests made by the
+#   Gemini CLI.
+#
+# Prerequisites:
+#   1. Export your Gemini API key:
+#      export GEMINI_API_KEY="your_api_key_here"
+#
+#   2. Generate a request payload from the Gemini CLI:
+#      Inside the CLI, run the `/chat debug` command. This will save the most
+#      recent API request to a file named `gcli-request-<timestamp>.json`.
+#
+# Usage:
+#   ./scripts/send_gemini_request.sh --payload <path_to_json> --model <model_id> [--stream]
+#
+# Options:
+#   --payload <file>  Path to the JSON request payload.
+#   --model <id>      The Gemini model ID (e.g., gemini-3-flash-preview).
+#   --stream          (Optional) Use the streaming API endpoint. Defaults to non-streaming.
+#
+# Example:
+#   ./scripts/send_gemini_request.sh --payload gcli-request.json --model gemini-3-flash-preview
