Alex Lopez-Cruz appeals the sentence imposed following his guilty-plea conviction for conspiracy to possess with intent to distribute cocaine. As part of his plea agreement, Lopez-Cruz waived the right to appeal his sentence except for “a good faith allegation that it was the result of ineffective assistance of counsel or prose-cutorial misconduct.” On appeal, he argues that his counsel was ineffective at sentencing for failing to object to the firearm adjustment applied to his sentence and for failing to bring information about responsibility for the firearm to the attention of the probation officer.

Because Lopez-Cruz did not raise this issue in district court, the record is not sufficiently developed for us to review the claim. See United States v. Cantwell, 470 F.3d 1087, 1091 (5th Cir. 2006). Accordingly, the judgment is AFFIRMED.
