actions/ai-inference

How actions/ai-inference works

This GitHub Action turns inline or file-based prompts into Copilot CLI requests, then exposes the model response as both an action output and a persistent temporary file. The main workflow is orchestrated by src/main.ts; prompt parsing and CLI execution are distinct stages, with src/helpers.ts providing legacy prompt loading, message assembly, and process-exit support. The README also documents YAML templates, file-backed variables, system prompts, and optional tool permissions. Edges reflect the shown calls and README workflow; unsampled action wiring is not inferred.
