Gitlab Mr Review

Automatically fetches and reviews GitLab merge requests using a template to identify issues and post detailed, actionable review comments.

This skill performs code reviews on GitLab merge requests using a standardized template.

Trigger

When user says something like:

• "帮我review这个mr: ${url}"
• "review this mr: ${url}"
• "帮我审查这个mr: ${url}"

Workflow

Step 1: Extract MR URL and Project Info

Parse the MR URL to extract:

• GitLab host (e.g., gitlab.snowballtech.com)
• Project path (e.g., bp/iot-admin-arco)
• MR IID (e.g., 1321)

Step 2: Configure glab for the GitLab instance

glab config set host https://<hostname>

Step 3: Fetch MR Information

glab api projects/<project>/merge_requests/<iid>

Step 4: Fetch MR Changes (Diff)

glab api projects/<project>/merge_requests/<iid>/changes

Step 5: Analyze the Diff

Read the review template at code-review-template.md and analyze the diff for:

• TODO/FIXME comments
• Unfinished code
• Hardcoded values
• Potential bugs
• Security issues
• Code style issues
• Missing error handling

Step 6: Generate Review Comment

Fill in the template with your analysis:

• 概述: Brief summary of what the MR does
• 优点: What went well
• 建议: Specific suggestions with file paths and line numbers
• 问题: Issues that need fixing
• 结论: Action items (checkboxes)

Step 7: Post Comment to MR

glab api projects/<project>/merge_requests/<iid>/notes --method POST \
  --raw-field body="$(cat review-comment.md)"

Or use inline with --raw-field body="<content>"

Tips

• Use emoji to highlight severity (🔴 for critical, 🟡 for warnings, ✅ for good)
• Be specific: include file paths and line numbers
• Provide actionable feedback
• Balance praise with constructive criticism
