Send a User-Uploaded Screenshot to the Agent
Problem/Feature Description
A developer is building a Koog 1.0 agent that helps developers debug UI bugs. The agent's input is a screenshot the user uploads plus a short text question ("what's wrong with this UI?"). The agent runs against Anthropic Opus, which accepts images.
In their app, the input arrives as a java.io.File reference to the uploaded screenshot. They want to wire it through a custom strategy that takes the file as input, builds a user message with the image attached, and asks the LLM to describe the problem.
Output Specification
Walk through the strategy. Produce the strategy and the node body that builds the message as a single Kotlin snippet, labeled.
