Grok Build 101: Grok Build, Role Division, and DoD

When using Grok Build, I feel that it is not merely a “tool that makes AI write code,” but a powerful team that lets one person run Scrum.

I interpret the relationship this way:

• Myself = Scrum Product Owner
• Grok Build = Scrum Master and Development Team

Role breakdown

My (Product Owner) responsibilities

• Decide the product vision and priorities
• Judge what to build and what not to build
• Give final approval for the merge to Production

Grok Build’s responsibilities

• Support planning and facilitate the process (Scrum Master)
• Implement, refactor, and write test code (Development Team)
• Deploy to the Staging environment once the Definition of Done is met

Whether this division of roles works well hinges on clearly defining the Definition of Done (DoD) at the Planning stage.

The core of the Definition of Done is “Playwright e2e”

The center of the DoD I currently operate is End-to-End testing with Playwright.

• Implementation of a feature alone does not mean “Done”
• It becomes “Done” only when all related Playwright e2e tests pass
• The moment it becomes Done, Grok is allowed to autonomously deploy to the GitHub Staging branch

In other words, the rule is: never push to Staging while the e2e tests are failing.

Because of this rule, I can give Grok considerable autonomy without quality collapsing.

Overall workflow

1. Planning – Define the feature requirements and the Playwright scenarios that will verify the feature together
2. Development – Grok proceeds with implementation, adjusting the plan as needed
3. Definition of Done – All Playwright e2e tests pass
4. Staging Deploy – Grok deploys to the Staging environment (automation is allowed up to this point)
5. Production – A human reviews Staging and, if there are no issues, manually merges to Production

Leaving the final “human Production decision” is important.

Grok is extremely capable, but I still believe the final business and risk judgment belongs in the human domain.

Why this model works

• Speed – Implementation through Staging can be turned around quickly
• Quality assurance – Because the DoD is fixed to Playwright, regression tests are forced with every feature addition
• Separation of responsibility – “Building” is Grok’s job; “finally releasing” is the human’s job. The boundary is clear
• Learning effect – The habit of writing e2e scenarios first in Planning naturally raises the precision of requirements definition

Conclusion

Once you master Grok Build, even a single person can operate a “Scrum team.” However, to make it work you must invest solid time in the planning stage to clearly define the DoD.
