Ludevina Ayala Cervantes appeals the district court’s denial of her petition for habeas corpus under 28 U.S.C. § 2255. Cervantes pled guilty to distribution of cocaine and entered into a plea agreement. The agreement included a waiver of the right to appeal her sentence. Despite the waiver, Cervantes attempted to appeal her sentence on direct appeal, but we dismissed the appeal based on the waiver. Cervantes then filed a petition for habeas relief with the district court. She *1108 alleged that the judge had incorrectly calculated her sentence. She further alleged that defense counsel had rendered ineffective assistance by inducing her to plead guilty based on misrepresentations as to what her sentence would be. The district court denied habeas relief. It held that sentencing issues are not cognizable under section 2255 and that the record of the sentencing hearing conclusively refuted any claim of inducement. On this appeal, Cervantes renews her claims of ineffective assistance of counsel and further contends that her waiver of the right to appeal her sentence was invalid. For the reasons that follow, we affirm.
I
On October 6, 1992, Cervantes was indicted by a Grand Jury and charged with conspiracy to distribute cocaine and two substantive counts of distribution of cocaine. At rearraignment on September 7, 1993, Cervantes, represented by counsel, entered a guilty plea to one count of distribution of cocaine under 21 U.S.C. § 841. The plea agreement included a waiver of her right to appeal any sentence ultimately imposed. At the sentencing hearing four months later, Cervantes received a sentence of 97 months in prison, five years of supervised release, and a fifty dollar special assessment.
Despite the appeal waiver provision in her plea agreement, Cervantes filed a motion for leave to appeal IFP, which the district court granted, appointing Cervantes’s previous counsel to represent her on appeal. On January 11, 1994, Cervantes filed a notice of appeal to this court. In March, the government responded with an unopposed motion to dismiss the appeal based on the appeal waiver. We dismissed the appeal on April 1, 1994.
On May 23, 1995, Cervantes filed a section 2255 petition for habeas relief. She contended that the court incorrectly calculated her sentence and that her counsel had rendered constitutionally ineffective assistance. Specifically, Cervantes alleged that the court erred by basing its sentence on the total amount of cocaine involved in the alleged conspiracy rather than the smaller amount she sold to an undercover agent. She further alleged that defense counsel was ineffective because he induced her to plead guilty with misrepresentations as to the sentence she would receive, he failed to challenge the amount of cocaine used to calculate her sentence, and he failed to prosecute the appeal of her sentence. The government filed an answer, asserting that Cervantes’s challenge of her sentence was not cognizable under section 2255 and, in any event, the appeal had been waived in the plea agreement. The government also responded that Cervantes’s inducement claim was refuted by her sworn testimony at the plea hearing.
Cervantes then filed an “amendment to section 2255 motion,” in which she requested that the district court accept two affidavits in support of her ineffective assistance of counsel claim. One affidavit, given by her sister Becky Ayala, stated that when she was at Cervantes’s counsel’s office, she heard him tell Cervantes that if she pleaded guilty and signed the plea agreement, Cervantes would receive only three to five years in prison based on an agreement with the government. The affidavit also asserted that on the day Cervantes was sentenced, her counsel told Cervantes he would file an appeal, but that later, he told her not to call him again. The other affidavit, given by Cervantes’s other sister, Delphie Whiteman, and her husband, stated that Cervantes’s counsel had assured them Cervantes would receive no more than five years in. prison based on an agreement with the government.
On May 17, 1996, the district court denied Cervantes’s section 2255 motion without an evidentiary hearing “for the reasons stated in the Government’s answer.” The court held that Cervantes’s “amendment” to the motion would not be considered because it was received after the government’s answer was filed, and Cervantes had not sought leave of court to file it. The court further concluded that, even if the affidavits were properly admitted, the facts asserted therein were effectively refuted by the terms of the plea agreement' and by Cervantes’s own statements under oath at the sentencing hearing.
Cervantes filed the present appeal. Although she had not requested a certificate *1109 of appealability (“COA”) from the district court, we treated her notice of appeal as an application for such and granted Cervantes a COA on whether the appeal waiver provision in her plea agreement was valid-which now appears to have been raised for the first time in this appeal-and whether her guilty plea was improperly induced. 1 In addition to these issues, Cervantes renews her claims that the district court erred in calculating her sentence and that her counsel was ineffective for not properly objecting to the amount of drugs used to calculate her sentence. Also, for the first time on appeal, Cervantes contends (1) that counsel was ineffective for not having requested a downward departure under the Sentencing Guidelines based on her family circumstances; (2) that the district court failed to comply with Rule 11; and (3) that the government breached the plea agreement by failing to make a specific sentencing recommendation.
II
As a threshold matter, we consider our standard of review and the extent to which Cervantes’s claims are cognizable un-dér section 2255. Following a conviction and exhaustion or waiver of the right to direct appeal, we presume a defendant stands fairly and finally convicted.
United States v. Shaid,
As the district court properly concluded, Cervantes’s claim that the trial judge erred -in -calculating her .sentence is not grounds for section 2255 relief. Technical application of the Sentencing Guidelines does not give rise to constitutional issues.
United States v. Vaughn,
Similarly, we need not address the merits of Cervantes’s claims regarding the validity of her appeal waiver, the district court’s compliance with Rule 11, the government’s alleged breach of the plea agreement, or ineffective assistance of counsel concerning failure to request a downward departure under the Guidelines. We do not consider issues raised for the first time on the appeal of a section 2255 motion.
See, e.g., United States v. Madkins,
Cervantes’s remaining claim-the only constitutional claim she properly raises-is that defense counsel rendered ineffec- tive assistance by wrongfully inducing her to provision of the plea
*1110
plead guilty.

As the case is presented to us today, however, the question is not the ultimate merits of this claim; instead, the precise question is whether the district court erred in denying the claim without granting an evidentiary hearing. We review the district court’s decision only for an abuse of discretion.
See United States v. Bartholomew,
Ill
A
Cervantes argues that her trial counsel rendered ineffective assistance by inducing her to plead guilty with misrepresentations regarding the sentence she would receive. Specifically, Cervantes contends that her counsel stated that she would receive a sentence of no more than 37 months in prison. She further alleges that counsel advised her that the plea hearing would be confusing, that she should agree to everything the judge said, and that he would handle the situation. The government responds that the statements made by Cervantes at the guilty plea and sentencing hearings, while under oath, refute her allegations. While Cervantes concedes her statements at these hearings, she argues that the record is bare with respect to the conversations she had with her attorney and, therefore, that the district court should have held an evidentiary hearing to resolve the issue. We, therefore, address whether the record before us requires a hearing on her claim of ineffective counsel.

To be constitutionally valid, a guilty plea must be knowing and voluntary.
Harmason v. Smith,
Nevertheless, a defendant may seek habeas relief on the basis of alleged promises, though inconsistent with representations she made in open court when entering her guilty plea, by proving (1) the exact terms of the alleged promise, (2) exactly when, where, and by whom the promise was made, and (3) the precise identity of an eyewitness to the promise.
See Harmason,
(2)
Cervantes submitted affidavits from her sisters regarding the alleged promises of her trial counsel, of which at least one satisfied the requirement of specificity necessary to warrant an evidentiary hearing.

Becky Ayala’s affidavit adequately described counsel’s alleged promises, who was present, as well as when and where the alleged promises were made. Cervantes, however, did not file the affidavits with her section 2255 motion, but instead, as an “Amendment to Section 2255 Motion.” The government had already filed a responsive pleading asserting that an
*1111
evidentiary hearing would be unnecessary because Cervantes’s claims of inducement were refuted by her testimony at the plea hearing. The district court, citing our decisions in
United States v. Armstrong,
Rule 15(a) permits parties to amend their pleadings after a responsive pleading has been served “only by leave of court or,by written consent of the adverse party.” In
Barksdale,
we held that because the defendant’s motion to dismiss was not a responsive pleading under Rule 15(a), the
pro se
plaintiff could amend his complaint once as a matter of course before the defendant filed a responsive pleading.

Cervantes is entitled to an evidentiary hearing only if the existing record proves the likely merit of her specific allegations of a promise.
See Davis v. Butler,
At rearraignment, the district court judge reiterated much of what was set forth in the plea agreement as well as the rights Cervantes would forfeit by pleading guilty, assuring Cervantes understood each of these matters. He specifically admonished Cervantes that she could not rely on anyone, even if connected to law enforcement or the government, for promises as to what her sentence would be. Cervantes represented to the court that she read and understood the entire plea agreement, agreed with its provisions, had consulted with her attorney, and had not been induced to sign the agreement by any promises, representations, or coercion. Finally, before confirming her guilty plea, Cervantes affirmed her understanding that she would not be permitted to withdraw the guilty plea even though the sentence she received might be harsher than she expected.
This testimony and the plain terms of the plea agreement clearly refute Cervantes’s allegations that her attorney had promised her a lower sentence based on an agreement with the government. The plea agreement is short, clear, and unambiguous. Cervantes’s colloquy with the court expressly contradicts the existence of any promises or agreements not contained in the plea agreement. Thus, the district court did not err in dismissing Cervantes’ habeas claim without conducting an evidentiary hearing on the issue of ineffective counsel.
See Smith,
IV
For the foregoing reasons, the district court’s denial of habeas relief is
AFFIRMED.
Notes
. We have recently held that a COA is unnecessary in section 2255 actions filed prior to the effective date of the AEDPA, April 24, 1996.
See Carter v. Johnson,
. In view of the fact that Cervantes has not properly raised the validity of the appeal waiver agreement, it is assumed valid.
See Shaid,
. Cervantes's claim that counsel was ineffective because he failed to renew overruled objections to the amount of cocaine used to calculate her sentence has no merit.
. We shall assume the affidavits of Cervantes’s sisters qualify as affidavits of "reliable” third parties.
