This is a controlled reproduction. Call orchestrator_capabilities once, then call delegate_task exactly once with target providerInstanceId "pi", model "anthropic/claude-haiku-5-5", task "Reply with exactly hello. Do not call any tools.", and synchronous completion (not background). Do not use any other tools. Quote the raw delegate_task result, including any error, in a JSON code block. Do not retry or change providers or models. Do not print workspace paths or credentials.
