Beta — Sentinel is in early access. We'd love your feedback!
Skill-driven AI code review directly in VS Code. Sentinel uses specialized review skills (security, performance, best practices) tailored to your tech stack — not generic AI prompts.
Features
Inline Diagnostics — Review issues appear as squiggly underlines in your editor, just like ESLint or TypeScript errors
Skill-Based Review — Automatically selects the right review skill based on your file type and framework (React, Node.js, Python, etc.)
Status Bar — One-click review from the status bar, with live issue count
GitHub Sign-In — Authenticate with GitHub for usage tracking and plan management
Multiple AI Providers — Groq (free), OpenAI, and Anthropic support
Quick Start

Open any code file
Run Sentinel: Review Current File from the Command Palette (Cmd+Shift+P / Ctrl+Shift+P)

How It Works
Sentinel reviews your code using skills — curated review rulesets for specific domains:
Backend / API — Security, input validation, error handling
Each skill knows what to look for in its domain, producing focused, actionable feedback instead of generic suggestions.
GitHub App
Sentinel also works as a GitHub App for automatic PR reviews. Install it on your repositories to get skill-driven review comments on every pull request.
