A desktop tool that lets you point at what you mean. Draw on your screen, and any CLI coding agent gets the annotated image as context.
Coding agents in the terminal are blind to the thing you are looking at. Describing a layout bug in prose is slow and lossy. You end up writing three paragraphs to say what an arrow would have said. Screenshots help, but wiring them into an agent's context is fiddly and different for every tool.
Annotate anywhere on screen, then hand the result to whichever agent you are already using. The tool is deliberately agnostic rather than bundled into one.
One-time purchase rather than a subscription. A utility you use daily should not be a recurring decision.
Ships as a real signed desktop app with its own update channel, not a script you have to babysit.
