Overview

Active Agent InlinePreviewInterceptor

Implements a agent preview interceptor that converts image tag src attributes that use inline cid: style URLs to data: style URLs so that they are visible when previewing an HTML prompt in a web browser.

This interceptor is enabled by default. To disable it, delete it from the ActiveAgent::Base.preview_interceptors array:

ActiveAgent::Base.preview_interceptors.delete(ActiveAgent::InlinePreviewInterceptor)
