## Why auth_oauth_save is rated Medium

This tool writes sensitive OAuth credentials to a local environment file. While not destructive (reversible) or financial, it is a Write operation that modifies configuration state. The severity is high because misconfigured or compromised OAuth credentials can lead to account takeover, unauthorized API access, and exposure of sensitive application secrets.

From the tool's own definition: "Saves OAuth credentials to .env.local - creates or modifies environment configuration files with sensitive authentication data."

Risk signals: Handles credentials or secrets (credentials)

## Use case

AI agents use auth_oauth_save to create or update resources in Yaver, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Yaver environment.
