Hi Everyone !
Let’s be honest most of us didn’t start using GitHub Copilot by reading documentation cover to cover.
We just installed it and hoped it would magically make our lives easier 😄
The good news? It actually can but not in the way you might think.
The trick isn’t learning every feature.
👉 It’s learning when to use Copilot and what to delegate to it.
Don’t Start with Features: Start with Your Task
Instead of asking:
“Which Copilot feature should I try?”
Ask yourself:
“What part of this task is boring, repetitive, or time-consuming?”
That’s where Copilot shines.
Think of it like a teammate:
- You keep the important decisions ✅
- Copilot handles the heavy lifting 💪
Copilot Chat = Your Coding Buddy
Copilot Chat is where things get interesting. It’s not just about writing code it helps you think.
Understanding messy code (we’ve all been there…)
You open a file and… 😵💫
- 5 dependencies
- random business logic
- unclear purpose
Instead of suffering, just ask Copilot to:
- explain what’s going on
- point out key dependencies
- suggest a safe refactor
Boom. Instant clarity.
Writing tests without losing your sanity
Writing unit tests = necessary, but not always fun.
Here’s a better approach:
- Write one simple test yourself
- Let Copilot generate the rest
It can help you:
- cover edge cases
- catch tricky scenarios
- think of things you might miss
Honestly, this alone can save hours.
Planning refactors like a pro
Before refactoring, don’t jump in blindly.
Ask Copilot to:
- suggest a cleaner design
- keep existing behavior intact
- show which parts will change
It’s like doing a mini design review without scheduling a meeting 😄
Working across code, config, and docs
Real work isn’t just writing C#.
You’re often dealing with:
- APIs
- configs
- OpenAPI specs
- docs
Copilot can connect the dots and say:
👉 “Hey, if you change this… you might also want to update that.”
That’s when it starts feeling less like autocomplete and more like a real assistant.
Debugging like a human (finally)
Build failed? Tests broken? 🫠
Instead of Googling random errors:
- paste it into Copilot
- ask what it means
- ask what to try next
You’ll get:
- plain English explanations
- targeted next steps
Way faster than jumping between Stack Overflow tabs.
Pro Tip: How to Write Better Prompts
Not all prompts are equal.
Bad:
“Fix this”
Better:
“Refactor this service to improve testability. Keep behavior the same and suggest test cases.”
See the difference?
Good prompts = better results.
When to Let Copilot Take Over (Agent Mode)
Sometimes, you don’t just want help you want the work done.
That’s where agent-style workflows come in.
Use them for things like:
- adding missing tests
- cleaning repetitive code
- fixing build issues
- updating multiple files
Basically, tasks where you can clearly say:
“Here’s what done looks like.”
Chat vs Agent (Simple Rule)
- Use Chat → when you need ideas, explanations, or plans
- Use Agents → when you want execution and results
Example:
- “Explain this service” → Chat
- “Refactor it and update tests” → Agent
Small Habits That Make a Big Difference
Want better results? Do this:
- Be clear about what you want
- Say what should NOT change
- Give context (code, errors, etc.)
- Always review the output (don’t blindly trust it 😄)
Treat Copilot like a junior dev very fast, very smart, but still needs guidance.
Final Thought
GitHub Copilot isn’t just about writing code faster.
It’s about:
- thinking better
- reducing boring work
- staying in flow
Use it where it makes sense:
- in your IDE
- in your terminal
- across your repo
And most importantly…
👉 Start with a real task from your backlog and let Copilot help.
That’s when it goes from cool tool → daily productivity boost 🚀
I hope that is helpful
May the knowledge be with you
