🐰 I hopped through lines of owners and names,
I nudged their order — no code to tame.
New guardians noted, some swapped in place,
A tidy CODEOWNERS, with rabbitly grace. 🥕

Pre-merge checks and finishing touches

❌ Failed checks (2 warnings)
Check name Status Explanation Resolution
Description Check ⚠️ Warning The PR description provides useful information about what the PR does and how to review it, but it does not follow the required template structure. The provided template specifies required sections including "📌 Description", "🔍 Related Issues", and "🚀 Pull Request Checklist" with specific checkboxes for pre-commit checks and tests. The author instead used custom section headings ("Summary", "Changes", "How to Review", "Notes") without including the template's structured format and checkboxes. While the content is relevant and informative, the failure to adhere to the specified template structure is a significant issue for consistency and process compliance. The PR description should be restructured to match the provided template format. Specifically, include the template's section headings, add the "Related Issues" section (even if no issues are linked), and include the "Pull Request Checklist" with all checkboxes for pre-commit checks and tests. While some sections may not be fully applicable to this automated maintenance PR, following the template structure ensures consistency and allows reviewers to quickly verify that standard checks have been considered.
Docstring Coverage ⚠️ Warning Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. You can run @coderabbitai generate docstrings to improve docstring coverage.

Title Check ✅ Passed The pull request title "chore: Update CODEOWNERS" directly and clearly describes the main change in the changeset. It uses the conventional commit format with the "chore:" prefix, which is appropriate for maintenance tasks like updating configuration files. The title is concise, specific enough to understand the primary change, and accurately reflects that the PR updates the CODEOWNERS file based on commit history analysis.

Code Review

This automated PR updates the .github/CODEOWNERS file. The change correctly reorders owners for the scripts/ path based on the analysis script. While reviewing the context, I noticed that the generation script has a flaw that can lead to duplicate owners, as seen on line 41 of the file. I have added a comment with details on the issue and a recommendation for fixing the script to improve future updates. The change in this PR itself is acceptable.

While this line has been updated correctly by the automation, the script that generates the CODEOWNERS file (scripts/codeowner_analyzer.py) appears to have a bug that can lead to duplicate entries. For instance, line 41 in this file lists @aleozlx twice.

This likely occurs because the generation script does not deduplicate the list of owners, which can happen if a single person contributes with multiple emails that resolve to the same GitHub username.

To prevent this in the future, the script should be updated to ensure the list of owners for any given path is unique. Using a set to collect the usernames before joining them into a string would be an effective solution.

⚠️ Potential issue | 🔴 Critical

🧩 Analysis chain

CODEOWNERS update for scripts/ path looks good.

The reordering of owners on line 43 reflects the commit activity analysis (frequency, coverage, and recency) from the 180-day git history window, which is the expected behavior from the automated workflow. All five owners remain assigned; only their sequence has changed based on contribution metrics.

If you'd like, you can verify that the new owner order aligns with actual commit contributions by inspecting the git history:


🏁 Script executed:

#!/bin/bash
# Description: Verify commit frequency for each owner in the scripts/ directory over the last 180 days

DAYS=180
DATE_SINCE=$(date -d "$DAYS days ago" +%Y-%m-%d)

echo "Commit frequency by author in scripts/ over the last $DAYS days (since $DATE_SINCE):"
git log --since="$DATE_SINCE" --pretty=format:"%an" -- scripts/ | sort | uniq -c | sort -rn

Length of output: 301


CODEOWNERS ordering for scripts/ does not match commit frequency—@yongwww and @dierksen are swapped.

The git log shows @yongwww with 5 commits and @dierksen with 2 commits over the past 180 days. The current line has @dierksen (position 3) ranked higher than @yongwww (position 4), which contradicts the stated contribution metrics.

Expected order: scripts/ @yzh119 @nvmbreughe @yongwww @dierksen @bkryu
Actual order: scripts/ @yzh119 @nvmbreughe @dierksen @yongwww @bkryu

Swap positions 3 and 4 to align with commit frequency.

🤖 Prompt for AI Agents
.github/CODEOWNERS around line 43: the owners list for scripts/ is ordered
incorrectly per commit frequency; swap the two handles so the line reads with
@yongwww before @dierksen. Edit the file to replace "scripts/ @yzh119
@nvmbreughe @dierksen @yongwww @bkryu" with "scripts/ @yzh119 @nvmbreughe
@yongwww @dierksen @bkryu" and commit the change.
