// ConvertGeminiRequestToAntigravity parses and transforms a Gemini CLI API request into Gemini API format.
|
|
// It extracts the model name, system instruction, message contents, and tool declarations
|

// from the raw JSON request and returns them in the format expected by the Gemini API.
|
|
// The function performs the following transformations:
|
|
// 1. Extracts the model information from the request
|
|
// 2. Restructures the JSON to match Gemini API format
|
|
// 3. Converts system instructions to the expected format
|

// 4. Fixes CLI tool response format and grouping
|

//
|
|
// Parameters:
|
|
// - modelName: The name of the model to use for the request (unused in current implementation)
|
|
// - rawJSON: The raw JSON request data from the Gemini CLI API
|
|
// - stream: A boolean indicating if the request is for a streaming response (unused in current implementation)
|
|
//
|
|
// Returns:
|
|
// - []byte: The transformed request data in Gemini API format
