Python Vibe Coding in VS Code with Copilot, ChatGPT, and Claude

Fast, fluent, feedback‑driven Python development for experienced developers.

---

What is “Vibe Coding”?

Vibe coding is a workflow where you stay in flow:

• You write intent, not boilerplate
• The editor completes, refactors, and explains
• You iterate rapidly with short prompts and tight feedback loops

VS Code is currently the best all‑round editor for this style, mainly due to deep AI integrations.

Prerequisites

• VS Code (latest stable)
• Python 3.10+
• GitHub account (for Copilot)
• OpenAI account (ChatGPT)
• Anthropic account (Claude, optional)

---

Step 1: Install Core VS Code Extensions

Install these in this order:

1. Python (Microsoft)
   • Language server, linting, debugging
2. Pylance
   • Fast IntelliSense and type inference
3. GitHub Copilot
   • Inline code generation and refactoring
4. GitHub Copilot Chat
   • Conversational coding inside VS Code

Reload VS Code after installation.

---

Step 2: Python Environment Setup (Critical)

Vibe coding breaks down if environments are messy.

Recommended:

python -m venv .venv
source .venv/bin/activate
pip install --upgrade pip

Then in VS Code:

• Ctrl+Shift+P → Python: Select Interpreter
• Choose .venv/bin/python

Enable auto‑activation in terminal:

"python.terminal.activateEnvironment": true

Step 3: Configure Copilot for Maximum Signal

How to open Settings (JSON) in VS Code

This step is not obvious if you are new to VS Code.

1. Press:

Ctrl + Shift + P

2. Type:

Preferences: Open Settings (JSON)

3. Press Enter

VS Code opens your global settings.json file.

---

Add the Copilot settings

Paste the following inside the { } braces. Make sure commas are correct:

Open Settings (JSON) and add:

{
  "github.copilot.enable": {
    "*": true,
    "plaintext": false,
    "markdown": true
  },
  "editor.inlineSuggest.enabled": true,
  "editor.suggest.preview": true,
  "editor.acceptSuggestionOnEnter": "on"
}

Why this matters:

• Copilot becomes predictive, not noisy
• Enter = commit intent, not newline hesitation

---

Step 4: Prompting Copilot Effectively (The Vibe)

Copilot reads comments, function names, and surrounding code.

Bad:

# do stuff

Good:

# Load OHLCV data from CSV, validate schema, return pandas DataFrame

Excellent:

"""
Load OHLCV data from CSV.
- Required columns: timestamp, open, high, low, close, volume
- Timestamp → pandas datetime (UTC)
- Raise ValueError on schema mismatch
"""

Then pause. Let Copilot write the function.

---

Step 5: Copilot Chat = Fast Refactor Engine

Use Copilot Chat for:

• “Refactor this into a reusable class”
• “Vectorize this loop”
• “Add type hints and docstrings”
• “Explain why this is slow”

Key rule:

Never accept blindly — skim, then accept.

---

Step 6: Add ChatGPT (OpenAI) to VS Code

Install one of:

• ChatGPT – Genie
• Continue
• Cursor‑style assistants

Configure with your OpenAI API key.

Best uses for ChatGPT:

• System‑level design discussions
• Architecture explanations
• Reviewing whole files or modules
• Generating test cases

ChatGPT is strongest when the question is bigger than the current file.

---

Step 7: Add Claude as a Second Brain (Optional but Powerful)

Claude excels at:

• Large context windows
• Reading long files
• Careful reasoning and refactors

Recommended workflow:

• Copilot → write code
• ChatGPT → design & exploration
• Claude → deep review & rewrite

Think of Claude as your senior reviewer.

---

Step 8: Keyboard‑First Flow (Important)

Memorize these:

• Tab → accept suggestion
• Esc → reject
• Ctrl+I → inline chat (extension‑dependent)
• Ctrl+Shift+P → everything

Mouse usage breaks the vibe.

---

Step 9: Tests, Linting, and Guard Rails

Add quickly:

pip install pytest ruff mypy

Configure minimal friction:

• Ruff for formatting + lint
• Pytest for confidence
• Mypy only on public APIs

AI + tests = speed and safety.

---

Common Anti‑Patterns

Avoid:

• Letting Copilot design architecture alone
• Giant prompts instead of incremental intent
• No tests (“AI will get it right”)
• Mixing environments

Vibe coding still requires taste and judgment.

---

Final Thoughts

Used correctly, VS Code with Copilot and modern LLMs feels less like coding and more like:

Directing a very fast, very literal junior developer

You stay in flow. The editor does the typing.

That’s vibe coding.
