Does it review the entire file or just the changes?

While it focuses on the diff, the skill reads the full file context to understand how the changes interact with the surrounding codebase and cross-cutting concerns.

Can it detect security vulnerabilities?

Yes, it specifically checks for high-severity issues like path traversal, injection, and authorization bypasses as part of its deep review checklist.

How does the skill access my GitLab instance?

The skill utilizes the GitLab MCP (Model Context Protocol) to interact with the GitLab API for fetching merge request details and posting inline comments.

What triggers the review process?

The review can be triggered by providing a GitLab MR URL or by using natural language commands like 'review MR' or '/review-mr {url}' in Claude Code.

Does it automatically merge the MR?

No, this skill is designed to provide feedback and facilitate the review process; the final merge decision remains with the human maintainer.

Collaboration Tools

Automates the GitLab code review process by analyzing Merge Requests and posting contextual inline feedback directly to the platform.

This skill streamlines the development workflow by handling the end-to-end process of GitLab Merge Request reviews. It extracts MR details from a URL, synchronizes local branches, and performs a deep analysis of code changes using context-aware inspection. By leveraging the GitLab MCP, the skill automatically publishes structured inline comments categorized by severity—from critical security vulnerabilities to stylistic improvements. This ensures high code quality and consistency while significantly reducing the manual effort required from human reviewers during the PR process.
