ChatGPT Linter
AI-powered code linter for VS Code, powered by ChatGPT and your own rules.
This extension allows you to define a custom rules (in plain text or Markdown), and have ChatGPT analyze your code for violations. Results are written to a JSON file and displayed as inline squiggles—just like ESLint.
✨ Features
✅ Analyze the active file using ChatGPT
✅ Custom rules support
✅ Inline squiggle diagnostics (warnings & errors)
✅ Uses OpenAI models (configurable)
✅ Fully customizable through VS Code settings
🚀 Getting Started
1. Install the Extension
Search for ChatGPT Linter in the VS Code Extensions Marketplace or install it manually from .vsix.
2. Set Your OpenAI API Key
In VS Code settings (Ctrl + ,):
ChatGPT Lint › Api Key For Open Ai
Set your OpenAI API key (get one here).
3. Create Your Style Guide
Create a file like chatgpt-linter-prompt.md in your workspace:
## Style Guide
- Use camelCase for variable names
- No `any` type
- Prefer `const` over `let` when not reassigned
You can use Markdown, plain text, or bullet lists.
How to Lint Your File
Run the command (Using VSC Cmd+Shift+P)
ChatGPT Lint: Generate Lint File
This will:
- Send the open file + rules to ChatGPT
- Generate a .chatgpt-lint.json file
- Show squiggles for any issues found
⚙️ Configuration Options
In settings.json or the VS Code settings UI:
| Setting |
Description |
Default |
chatgptLinter.apiKeyForOpenAi |
Your OpenAI API key |
"" |
chatgptLinter.model |
Model to use (gpt-4, etc.) |
"3o-mini" |
chatgptLinter.stylePath |
Path to your rules file |
"./chatgpt-linter-prompt.md" |
chatgptLinter.lintFileName |
Output file for lint results |
".chatgpt-lint.json" |
🧠 How It Works
- The extension sends both your code and your custom rules to ChatGPT via OpenAI’s API
- ChatGPT reviews your code. The results are saved to
.chatgpt-lint.json
- Squiggles appear automatically using VS Code’s Diagnostics API, like eslint does.
🔐 API Usage & Rate Limits
This extension uses your own OpenAI API key. Make sure your key is valid and you’re aware of your rate limits and token quotas.
💡 Tips
- You can use different models for faster/cheaper responses
- You can use other tools to generate
.chatgpt-lint.json to make squiggles
show up. The built-in command is just one option.
