Developed and delivered an automated pull request size validation workflow for the SolaceLabs/solace-agent-mesh repository, focusing on improving code review discipline and merge readiness. The solution leveraged GitHub Actions and YAML to compute the total lines changed in each pull request, enforcing a strict 1500-line limit. By integrating this workflow into the repository’s continuous integration pipeline, the process automatically triggers on PR events such as opening, synchronizing, or reopening. This governance-oriented automation supports optional branch protection, ensuring that oversized pull requests are flagged before merging. The work demonstrates practical application of DevOps principles and continuous integration best practices.
