WHY IT NEEDS A POLICY

Why set-zerodha-tokens needs a policy

This tool writes authentication tokens (request token and access token) to a configuration file. It modifies stored credentials persistently, which is a Write operation. The severity is high because misuse could allow an attacker to hijack the Zerodha session by setting malicious tokens, potentially enabling unauthorized access to trading operations including financial transactions.
