Stats of GitHub PRs opened/merged by LLM agents

aavetis/PRarena. Albert Avetisian runs this repository on GitHub which uses the Github Search API to track the number of PRs that can be credited to a collection of different coding agents. The repo runs this collect_data.py script every three hours using GitHub Actions to collect the data, then updates the PR Arena site with a visual leaderboard.
