Worked on the plone/cookieplone-templates repository to improve the stability and maintainability of the continuous integration workflow. Focused on backend acceptance test automation, the developer removed the -dev flag from acceptance commands and updated the related Makefile target, addressing inconsistencies in command naming and streamlining the CI build process. Using Makefile and DevOps practices, these changes were integrated through a series of commits that also included a news entry and fixes for CI configuration. The result was a more reliable and faster acceptance test process, with improved onboarding and maintainability due to standardized command usage and clearer build automation.
