PR Code Suggestions

💡 Suggestion:

Consider handling potential exceptions when retrieving repository labels.

File: pr_agent/git_providers/gitlab_provider.py (414-415)

Example code:

---

Existing code:

def get_repo_labels(self):
    return self.gl.projects.get(self.id_project).labels.list()

Improved code:

def get_repo_labels(self):
    try:
        return self.gl.projects.get(self.id_project).labels.list()
    except Exception as e:
        print(f"Error retrieving repository labels: {e}")
        return None

💡 Suggestion:

Consider caching the result of the get call to avoid multiple network requests.

File: pr_agent/git_providers/gitlab_provider.py (414-415)

Example code:

---

Existing code:

def get_repo_labels(self):
    return self.gl.projects.get(self.id_project).labels.list()

Improved code:

def get_repo_labels(self):
    if not hasattr(self, '_repo_labels'):
        self._repo_labels = self.gl.projects.get(self.id_project).labels.list()
    return self._repo_labels

💡 Suggestion:

Consider returning an empty list instead of None when there are no labels.
