I earned the GitHub Certified: Agentic AI Developer (GH-600) certification after taking the exam during its beta period, when there were no official practice exams, very limited community guidance, and a months-long wait while Microsoft and GitHub validated the exam before general availability.
The exam covered the engineering around coding agents: GitHub Copilot, agent workflows, MCP, GitHub Actions, orchestration, governance, and human review across the software-development lifecycle.
