You don’t need to learn these — your AI discovers them automatically when it connects, and calls fetch_instructions to teach itself the full Visk format before building anything. This page is a reference for what’s under the hood.

How a session works

Everything happens inside an editing session. The AI starts one with create_pptx_session and gets back a session id; the deck then lives on Visk’s side, so each edit is a small, targeted call rather than re-sending the whole document, and the AI can come back to the same id later to pick up where it left off.

A typical flow

create_pptx_session  →  upload your template
add_slides           →  build on the master layouts
screenshot           →  check the result, fix what's off
export               →  download the finished .pptx
