Overview

Handles ERB template rendering for prompt actions via ActionView.

Templates are resolved from the view paths configured on the prompt class (defaults to app/views/ in a Rails app). The lookup path convention is:

app/views/action_prompts/<prompt_class_name>/<action_name>.text.erb

Examples

ArticleSummarizerPrompt  ->  action_prompts/article_summarizer_prompt/summarize.text.erb
Admin::ReportPrompt      ->  action_prompts/admin/report_prompt/generate.text.erb
