Some ideas for extension

[hossain-khan]

Here are some ideas for additional reports that could enhance the existing PR statistics reporting in the hossain-khan/github-stats repository:

1. PR Size and Complexity Report

   • Analyze and visualize the average and distribution of PR sizes (lines added, lines deleted, number of files changed).
   • Correlate PR size with review/merge time to show whether larger PRs take longer to review and merge.

2. Inactive/Abandoned PRs Report

   • Identify PRs that remained open for an extended period without activity or were closed without merging.
   • Track reasons (e.g., lack of review, requested changes not addressed) and provide actionable insights to avoid future stagnation.

3. Reviewer Responsiveness Report

   • Measure and visualize the average response time of each reviewer from the moment a review is requested to the first comment or review.
   • Spot reviewers who are most/least responsive and identify bottlenecks in the review process.

4. Cross-Team/External Contributions Report

   • Analyze PRs created or reviewed by contributors outside the core team or organization.
   • Highlight community engagement, first-time contributors, and their impact on the project.

5. Code Review Comment Quality/Depth Report

   • Go beyond counting comments: categorize code review comments by type (suggestion, question, required change, approval) using simple text classification.
   • Provide metrics on the nature and helpfulness of review comments.

6. Velocity and Throughput Trends

   • Track the number of PRs merged, average time to merge, and review counts over time (weekly/monthly trends).
   • Identify periods of high/low productivity or backlog build-up.

7. Churn and Rework Report

   • Measure how often code in merged PRs is changed or reverted soon after merging.
   • Spot files or areas of the codebase prone to frequent rework, indicating possible technical debt or unclear requirements.

Here are three feature ideas that build on the current functionality of the hossain-khan/github-stats repository, leveraging GitHub API data:

1. Contributor Activity Heatmap
   Visualize each contributor’s activity (commits, pull requests, reviews, comments) as a calendar heatmap, similar to the GitHub contribution graph. This will enable quick identification of peak activity periods and help teams recognize key contributors and trends over time.

2. Automated Team Performance Reports
   Generate periodic (weekly/monthly) automated reports that summarize team performance, including PR review turnaround times, number of PRs opened and merged, issues resolved, and average time to close. These reports could be delivered via email, Slack, or as downloadable PDFs, and would help teams track progress and identify areas for improvement.

3. PR Review Bottleneck Detection
   Analyze open pull requests and reviewer assignment data to automatically detect bottlenecks — for example, PRs waiting too long for review, or reviewers who are overloaded. The system could suggest optimal reviewer distribution based on current workload and provide actionable alerts to maintain healthy code review flow.
