For these scenarios, high-resolution screenshots provide limited additional value.\n\n## Proposal\n\nIntroduce an optional way to downscale screenshots before they are sent to the LLM.\n\nThis would:\n\t•\tReduce multimodal token usage and cost\n\t•\tSpeed up longer automation runs\n\t•\tBetter support flow-validation-focused workflows\n\nThe feature could be opt-in and configurable, preserving current behavior by default.\n\n## Why This Matters\n\nThis would make XcodeBuildMCP more efficient for common UI automation use cases where correctness matters more than visual detail, without impacting users who rely on full-resolution screenshots.\n\n\n### Use Cases\n\t•\tAutomated UI tests that validate navigation flows across multiple screens\n\t•\tRegression testing where the presence or absence of UI elements matters more than layout precision\n\t•\tLong-running or repeated automation runs where screenshot token cost accumulates quickly\n\t•\tCI-based UI automation focused on correctness rather than visual QA\n\n### Example Interactions\n\t•\tAn agent navigates through an onboarding flow and uses downscaled screenshots to confirm each step was reached successfully\n\t•\tAn automated test verifies that tapping a button transitions to the expected screen without requiring high-fidelity visual input\n\t•\tA flow validation run captures many screenshots while keeping LLM input costs low","author":{"url":"https://github.com/noskovvkirill","@type":"Person","name":"noskovvkirill"},"datePublished":"2025-12-27T17:37:54.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/154/XcodeBuildMCP/issues/154"}
