CodeRifts — OpenAI Function Calling Example

Demonstrates how to add CodeRifts enforcement to OpenAI function calling, blocking unsafe API calls before execution.

Quick Start

pip install requests
python main.py

How It Works

The handle_tool_call function wraps every tool execution with a CodeRifts preflight check:

def handle_tool_call(tool_call):
    args = json.loads(tool_call["arguments"])
    decision = coderifts_preflight(args["spec_url"])

    if decision["decision"] == "BLOCK":
        return json.dumps({"error": "blocked_by_coderifts"})

    # Safe to proceed
    return execute_api_call(args)

The model receives the block result as a tool response and can explain to the user why the call was blocked.

Example Output

[OPENAI] Model wants to call API at https://petstore3.swagger.io/api/v3/openapi.json
[CODERIFTS] decision=ALLOW risk=12
[OPENAI] Executing /orders/123 on https://petstore3.swagger.io/api/v3/openapi.json
[OPENAI] Tool call succeeded: {"status": "success", "data": {"order_id": "12345"}}
