The Github Jira Integration Extension is a free Chrome add-on developed by gustarus. This extension allows users to seamlessly link ticket numbers in pull requests with Jira tasks, providing a smooth integration between the two platforms. With this extension, users can easily replace ticket numbers with clickable links to Jira tasks, making it convenient to navigate between the two systems.

Additionally, the extension offers the option to add a link to a Jira task for every comment made in pull requests. This feature enhances collaboration and facilitates communication by providing direct access to relevant Jira tasks when discussing pull requests.

Another useful feature of this extension is the ability to block the merge of pull requests if the title contains "wip" or "[wip]". This helps enforce best practices and prevents merging of work-in-progress pull requests, ensuring that only completed and reviewed code is merged.

Overall, the Github Jira Integration Extension is a valuable tool for developers and teams using Github and Jira, providing seamless integration and enhancing collaboration between the two platforms.
