About twitch_extension_tools
twitch_extension_tools is a desktop test tool described as an alternative to the Twitch Developer Rig. It works as a REST client for Extension APIs and handles JWT creation and App Access Token generation and maintenance.

twitch_extension_tools FAQ
Why does extension validation keep failing with authentication failed?
The tool creates JWTs with a 4-second expiration, so if the system clock is significantly out of date it can generate an already expired token. Check that the system clock is accurate.
