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.

| Command | Description |
|---|---|
| CodeCritic: Review selection | Selected text in the active editor |
| CodeCritic: Review active file | Whole file |
| CodeCritic: Review files… | Pick one or more files |
| CodeCritic: Review folder… | Text files under a folder (limits apply) |
| CodeCritic: Open last review result | Refetch last UUID for this workspace |
| CodeCritic: Open sidebar | Focus the CodeCritic activity bar view |
Context menu: review selection / active file when an editor is open. The sidebar exposes the same actions and recent history.
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.
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.
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.
