CodeCritic (VS Code / Cursor)

CodeCritic is a second opinion for AI-written code. Install this extension from the official editor marketplaces, then review selection, file, or folder without leaving VS Code or Cursor.

The CodeCritic activity bar opens a sidebar (API key, review actions, recent reviews). Results open in a panel: score, issues, suggestions, Trust focus, Mark as done / Dismiss, line jump, and Fix in Chat.

Extension ID: CodeCritic.codecritic-vscode

Install

Visual Studio Code

1. Open Extensions (Ctrl+Shift+X / Cmd+Shift+X).
2. Search for CodeCritic (publisher CodeCritic).
3. Click Install.

Or open the Visual Studio Marketplace listing, or from a terminal:

code --install-extension CodeCritic.codecritic-vscode

Cursor

Cursor uses an Open VSX-compatible marketplace (not the Microsoft Marketplace).

1. Open Extensions (Ctrl+Shift+X / Cmd+Shift+X).
2. Search for CodeCritic (publisher CodeCritic).
3. Click Install.

Or open the Open VSX listing, or from a terminal:

cursor --install-extension CodeCritic.codecritic-vscode

If search does not show the extension yet, install the same ID from Open VSX or use Extensions: Install from VSIX… with a release build from the GitHub repository.

Requirements

• VS Code 1.80+ or Cursor
• A CodeCritic account and API key from Dashboard → Settings → API key

Setup

1. Open the CodeCritic sidebar (activity bar) or run CodeCritic: Set API key and paste your key (Secret Storage).
2. Optional: CodeCritic: Open Dashboard (API key) to copy or rotate the key in the browser.
3. Optional setting codecritic.apiBaseUrl (default https://api.code-critic.com). For local Rack, use http://localhost:9292/api.

Commands

Context menu: review selection / active file when an editor is open. The sidebar exposes the same actions and recent history.

Auth

The extension sends Authorization: Bearer <API key> to /v1/code_reviews on the API host (default https://api.code-critic.com). Billing matches the web app.

Troubleshooting

HTTP 404 / “Not Found”: codecritic.apiBaseUrl must be the API host (e.g. https://api.code-critic.com), not the marketing site.

ByteString / character greater than 255: Re-run CodeCritic: Set API key and paste the key only from the dashboard, then reload the window.

Review timed out / Connect Timeout: The extension retries connect failures. If the panel never opens, use CodeCritic: Open last review result - create may have succeeded on the server. On WSL/VPN, a second try often works.

Limits

Combined payload size is capped (default 20,000 characters on the server). Folder mode skips very large files and common dependency directories.

Trust focus, pay-per-use, and other preferences are configured in the web app only.

Development

npm install
npm run watch   # extension + webview
npm test        # unit tests (Vitest)
npx vsce package --no-dependencies   # local .vsix for sideload testing

Press F5 with this folder open (launch config: Run Extension) to start the Extension Development Host.
