Different AI coding agents follow different workflows when creating pull requests:

• All PRs: Every pull request created by an agent, including DRAFT PRs
• Ready PRs: Non-draft pull requests that are ready for review and merging
• Merged PRs: Pull requests that were successfully merged into the codebase

Key workflow differences: Some agents like Codex iterate privately and create ready PRs directly, resulting in very few drafts but high merge rates. Others like Copilot and Codegen create draft PRs first, encouraging public iteration before marking them ready for review.

The statistics below focus on Ready PRs only to fairly compare agents across different workflows, measuring each agent's ability to produce mergeable code regardless of whether they iterate publicly (with drafts) or privately.
