常见问题

What are the prerequisites?

Python 3.8+ and Google Chrome browser are required.

How do I capture a response?

Run `python main.py monitor --prompt "your prompt"`. The script connects to Chrome, navigates to v0.dev, submits the prompt, and saves captured network data to the `captures` directory.

What file types does the tool create?

It saves four file types: `sse_stream_*.jsonl` (raw SSE data), `sse_decoded_*.jsonl` (decoded JSON events), `assembled_content_*.txt` (assembled text), and `full_response_*.txt` (cleaned final response).

How can I extract a captured response later?

Use `python main.py extract captures/full_response_1234567890.txt` to parse the file and display the clean text in the terminal.

What if responses aren’t captured properly?

Close all Chrome instances and let the script launch a new one. Increase the monitoring time in `tools.py` if needed.
