Moisten the rim of a short glass with a lime wedge, then dip in kosher salt; fill with ice. Combine 2 ounces tequila, 1 ounce orange liqueur (such as Cointreau), 1 1/2 ounces fresh lime juice and 1/4 ounce each fresh orange juice and agave nectar in a shaker with ice. Strain into the prepared glass. Garnish with a lime wedge.
