What issue are you seeing?
Computer Use tool calls to @oai/sky run, and nodeRepl.write / nodeRepl.emitImage appear to execute successfully. However, the tool output visible to the assistant only shows metadata or no payload at all — the actual image content is missing. As a result, Computer Use cannot inspect screenshots b

ecause the content[] array returned by node_repl over MCP is not being surfaced to the model.
What steps can reproduce the bug?
Start a Computer Use session using @oai/sky. Call nodeRepl.write or nodeRepl.emitImage to emit a screenshot/image. Observe that the call executes without error. Inspect the tool output available to the model — only metadata (or nothing) appears instead of the image payload.
What is the expected behavior?
The content[] array returned by node_repl over MCP (including image/screenshot payloads from emitImage) should be surfaced to the model, so Computer Use can actually inspect the screenshot rather than just metadata.

This is related to #36765 in that successful MCP results are not surfaced to the model/UI, but this report is specifically about node_repl result content[] being discarded when structuredContent is present, without nested MCP Apps or widget rendering involved
