GitHub 观点：AI 改变开发者工作后该练的三种技能——指挥 AI、不轻信第一答案、把权衡讲清楚

Learn to direct AI agents, critically review their output, and keep technical judgment at the center of your workflow.

AI is changing how developers work and apply their skills. Writing code is still essential, but developers increasingly need to know how to direct AI, evaluate its output, communicate tradeoffs, and make sound technical decisions.

The good news? You can start preparing today. Here’s where to focus:

Tip #1: Learn to direct AI, not just use it.

AI is changing what execution looks like. Increasingly, great execution means defining the problem clearly, providing the right context, evaluating AI-generated code, and deciding what’s ready to ship. As AI agents take on more of the implementation, these skills become even more valuable.

For example, imagine you’re asked to add a new authentication flow.

A traditional workflow might look like this:

Task: Add authentication  

→ Create branch  
→ Write code  
→ Run tests  
→ Open pull request

As AI tools become more capable and more deeply integrated into day-to-day workflows, those same skills can help you coordinate multiple AI agents. Your workflow might look more like this:

Workspace: Add authentication  

Agent 1 ✓ Authentication ready for review 
Agent 2 ✓ Documentation draft ready  
Agent 3 ✓ Test suite ready

Notice what changed. You’re still responsible for the outcome, but you’re spending less time implementing every piece yourself. Instead, you’re defining the work, reviewing outputs, and making the technical decisions that bring everything together.

Takeaway: Learn to direct AI agents.

Tip #2: Don’t trust AI’s first answer

AI can generate impressive solutions in seconds, but the first answer isn’t always the best. Your experience writing clean, maintainable code can help you evaluate AI’s output.

Ask a second AI model to critique the first model’s work, then use your own judgment to evaluate both responses.

Here’s a prompt that shows what that might look like in practice:

"Write a SQL query that returns each customer's most recent order." 
↓ 
AI Model #1 
✓ Generates the query 
↓ 
AI Model #2 (Critique) 
⚠ Doesn't handle duplicate timestamps 
⚠ Missing index recommendation 
⚠ May perform poorly on large tables

Different AI models have different strengths and blind spots. That’s why GitHub Copilot’s built-in Rubber Duck agent uses a second model to critique plans, code, and tests before you move forward. A second perspective often catches issues the first model misses.

Takeaway: Trust AI enough to use it but not enough to skip review.

Tip #3: Use AI to solve bigger problems

When AI saves implementation time, developers can use that time to tackle broader problems: understanding customer needs, evaluating tradeoffs, designing better systems, and making technical decisions that AI can’t make for them.

Issue #4821 
Title: Add dark mode 

AI 

✓ Build implementation 
✓ Generate tests 
✓ Update documentation 

Developer checklist 

☐ Validate customer problem 
☐ Review architectural tradeoffs 
☐ Check accessibility 
☐ Define success metrics 
☐ Approve solution 

As AI takes on more implementation work, the skills that distinguish great engineers become even more important: exercising sound judgment, balancing tradeoffs, and solving the right problems.

Takeaway: Let AI handle more of the implementation so you can spend more time building the judgment that helps teams make better decisions.

The bottom line

As developer workflows evolve, learning to work effectively with AI—and strengthening your own technical judgment—can help you adapt.

Developers aren’t becoming more careless; they’re being outpaced. The tools that let developers create more software should also take on more of the work of protecting it.
