✅ Step-by-Step Solution

🔁 1. Switch to a Stable Model

The GPT-4.1 model has known issues in Agent Mode. Switch to GPT-4 or GPT-4o instead.

How to switch:

1. Open VS Code

2. Press Ctrl+Shift+P (or Cmd+Shift+P on Mac)

3. Type: Copilot: Change Chat Model

4. Select: gpt-4 (or gpt-4o if available)

---

🔧 2. Disable Agent Mode (Temporarily)

If Agent Mode is unstable, disable it and use regular Copilot Chat:

1. Open Command Palette: Ctrl+Shift+P

2. Type: Copilot: Disable Agent Mode

You can still use Copilot Chat for smart code suggestions without Agent Mode bugs.

---

🔄 3. Update Everything

Ensure you have the latest versions:

• VS Code: Update from Help > Check for Updates

• GitHub Copilot Extension:
  In Extensions (Ctrl+Shift+X) → Search "GitHub Copilot" → Click ⚙️ → "Check for Updates"

---

🚀 4. Clear Copilot Cache

Sometimes corrupted config causes misbehavior:

1. Open terminal in VS Code

2. Run:

   rm -rf ~/.vscode/extensions/github.copilot-*
   

3. Reinstall the Copilot extension from the Marketplace.

---

🌐 5. Check GitHub System Status

See if GitHub Copilot is having outages:
https://www.githubstatus.com

---

🛠 Optional: Re-authenticate Copilot

1. Press Ctrl+Shift+P

2. Type Copilot: Sign Out

3. Then sign in again.

---

✅ Summary

Problem	Fix
GPT-4.1 Agent Mode bugs	Switch to gpt-4 or gpt-4o
Agent not applying changes	Disable Agent Mode temporarily
Extension not working properly	Update & clear cache
Copilot hangs on push	Check DNS or GitHub status

---

Let me know if you'd like a script to automate the model switch or clean reinstall process.

I'm encountering issues with the GitHub Copilot Agent in Visual Studio Code while using the GPT-4.1 model. Despite having an active Copilot Premium subscription, the agent is no longer functioning as expected — it fails to apply meaningful edits or code changes based on prompts that previously worked reliably.

I would appreciate clarification on whether this behavior could be related to usage limits, recent updates, or potential service instability.

For context, I rely on this tool extensively in my development workflow at AgileTech.

Thank you in advance for your support and any recommendations you can provide to resolve this.
