Customising GitLab Duo Chat with Rules, Prompts, and Workflows

Enhancing Productivity with Custom GitLab Duo Chat Rules, Prompts, and Workflows

GitLab’s commitment to AI-fuelled developer experience continues to evolve with its flexible Duo Chat tool. The latest improvements allow you to customise Chat’s behaviour, adapt prompts to your team’s workflow, and refine the responses that suit your organisation’s unique needs. Whether you’re an individual contributor or part of an enterprise team, these enhancements are designed to boost software delivery efficiency and collaboration.

By allowing direct prompt editing for specific use cases like summarisation or code explanations, GitLab Duo Chat encourages tailored interactions instead of generic replies. You can now build, test, and iterate custom prompts within your GitLab project repository using an extensible YAML format—all version-controlled, collaborative, and transparent.

Key benefits include prompt versioning, collaborative editing through merge requests, and tight integration within your DevSecOps workflow. Teams can design stricter or more conversational AI responses depending on context—bring standardisation or creativity into your development pipelines as needed.

If you’re working across teams with different domains or workflows—from testers to security reviewers—Duo Chat can cater to each context individually. For example, test engineers might integrate prompts to assist with test suite generation, while platform engineers might request Kubernetes configuration advice.

GitLab’s open prompts repository also enables inspiration and standardised examples. Users can contribute back to the community and leverage evolving best practices around prompt engineering within the GitLab ecosystem.
