Pull Request has become a central part of our workflows. They empower us with the ability to discuss and review code changes, bug fixes, features, and others, before merging into the codebase.
From crafting to reviewing pull requests, these are really mentally draining tasks for developers. Most of us at various workplaces feel stuck, awaiting our PRs to be merged or rejected, which always seems to be “in review”. This is no surprise as maintainers are required to understand the scope and changes made to the codebase which is time-consuming and really hard.
Taking advantage of AI, more products have started to emerge to help us with this workflow. Empowering us with features that help us craft better Pull Requests and most importantly, help maintainers understand our Pull Requests better. GitHub's Copilot for Pull Requests is a great example of this, but there is an even better option, Codium.ai PR-Agent.

/improve with extra instructions - Pro feature
/Improve is a command that allows Codium’s PR-Agent to improve the quality of your pull request, which is already a great feature, but It gets even better with the custom Instructions. Having the ability to customize what and how the AI should Improve on your code in some particular areas or based a theme.

This broad compatibility places Codium’s PR-Agent in a superior position compared to Copilot for PR, catering to diverse developer environments and ensuring broader accessibility and utility.
