This article presents a simple workflow for maximizing productivity with GitHub Copilot by focusing on the harness (the core agent workflow) rather than complex prompts or tools. It outlines eight steps: selecting a tool close to the harness, enabling YOLO mode for autonomy, starting with prototypes to explore options, methodical planning, automated implementation via Autopilot, human review and iteration, cross-model Rubber Duck review, and finalizing. The key takeaway is that simplicity and deep understanding of the harness yield better results than chasing gimmicks.

• Focus on the harness instead of gimmicks.
• Enable YOLO mode for agent autonomy.
• Start with prototypes to uncover requirements.
• Plan methodically and implement with Autopilot.
• Use Rubber Duck review for cross-model validation.
• Human review and iteration are essential.
• Simplicity yields better results.

The GitHub Copilot app is designed for real software development workflows, offering project-connected agent sessions, multi-thread conversations via Quick Chat, interactive canvas for UI previews, and Agent Merge to automate pull request tasks. It allows developers to manage multiple tasks without losing momentum, from exploring codebases to shipping changes.

• Project-connected sessions provide full repository context for each task.
• Multiple agent sessions can run simultaneously without interruption.
• Quick Chat allows quick questions while other sessions continue.
• Interactive canvas enables live preview and direct UI manipulation.
• Agent Merge automates pull request feedback, CI fixes, and merges.
• Workflow integrated: from coding to review to merging in one place.
