🧼 Code Smeller

Code Smeller is a fun, lightweight VS Code extension that helps developers write cleaner, more maintainable code using both LLM-powered reviews and your editor's built-in linting system.

It reviews your code for:

  • Poor or vague variable naming
  • Refactoring opportunities (DRY, SRP, etc.)
  • Violations of language/framework best practices

All feedback is shown in a friendly markdown-powered side panel — complete with a "smell score" and quote from your favorite anime crew to set the tone. Think of it as your AI-powered code reviewer... with personality.


✨ Features

  • ✅ Live smell detection using VS Code's own diagnostic engine. No extra linters required
  • ✅ One-click code reviews powered by Gemini (optional)
  • ✅ Smell Score (1–5) with themed quotes and custom Luffy images
  • ✅ Real-time syntax smell score updates as you type
  • ✅ Dynamic caching — reviews are cached per file, refreshed every 3 days or on VS Code close
  • ✅ User-defined supported languages with Code Smeller: Add Language
  • ✅ Supports any language with active VS Code diagnostics (JS, TS, Python, etc.)
  • ✅ Secure API key management via VS Code SecretStorage
  • ✅ Lightweight and non-intrusive design

Code Smeller in Action

💡 Tips

  • You don’t need to manually run anything! Code Smeller updates in the side panel as you write, giving you instant insight without breaking your flow.
  • Linting quality depends on the language extension and settings you have installed. Ensure tools like ESLint or the Python extension are properly set up in your workspace.
  • For deeper insights, you can trigger a Gemini-powered review anytime via the Command Palette.

⚙️ Extension Settings

This extension contributes the following VS Code settings:

Setting Description
codeSmeller.apiKey (Optional) Store your Gemini API key. Prefer using SecretStorage.

📦 Commands

Command Description

Code Smeller: Set Gemini API Key Securely store your API key using VS Code SecretStorage
Code Smeller: Add Language To Supported Languages Adds the current file’s languageId to the supported list

🖼️ Smell Score System

Code Smeller assigns a smell score from 1 (clean) to 5 (disaster), using custom illustrations to match each level of code hygiene. The images appear in the side panel alongside Luffy-style quotes to keep things fun and helpful.

Score Meaning Visual Expression Quote
1 ✨ Squeaky clean “Shishishi~! This code’s tighter than anchor rope!”
2 🧐 Slightly off “Oi... it’s decent, but somethin’s off in the wind.”
3 😐 Needs cleanup “It’s not the worst, but it needs serious polish.”
4 🤢 Smelly “Too much goin’ on — clean it up or we’ll sink!”
5 ☠️ Code is lethal “THIS CODE’S A DISASTER! PATCH THE HOLES!!”

Each review starts with the appropriate image and quote, followed by a markdown-rendered breakdown of real, actionable feedback.


🐞 Known Issues

  • Markdown rendering may fail if CDN access to marked.js is blocked
  • Very large files may be truncated due to token limits in the LLM
  • Live Syntax code smell only supports JavaScript, TypeScript, and Python for now

🔐 Security Note

Your Gemini API key is stored securely using VS Code SecretStorage. You can update or remove it anytime via the Command Palette.
