TL;DR this PR

TL;DR this PR is a lightweight Chrome extension that helps you quickly understand what a GitHub pull request actually does before you spend time reviewing it. It adds a simple button to PR pages that generates a concise summary, highlights potential risks, and surfaces the parts of the code that matter most. **What it does** *Instant summaries* Get a clear 3–4 bullet overview of what the PR changes *Size and risk classification* Labels PRs as trivial, medium, large, or high-risk based on scope and impact *File-level insights* Groups changed files by purpose (auth, database, tests, etc.) so you know where to focus *Quality signals* Flags patterns like vague commits, overly complex naming, or suspicious changes across critical areas *Explainable output* Every summary and warning includes reasoning, not just conclusions *Works natively on GitHub* Integrates directly into PR pages with no extra setup or workflow changes **How it works** The extension reads the pull request content (title, description, commits, and diff) and sends it to a language model via OpenRouter to generate structured analysis. **Setup** Requires a free OpenRouter API key No account or backend required All analysis is triggered manually on PR pages **Privacy** This extension sends pull request content (including diffs and descriptions) to a third-party API (OpenRouter) for analysis. No data is stored or tracked by the extension. **Why this exists** Reviewing pull requests is often slow and noisy. This tool is built to answer a simple question: “Is this PR worth my time right now?”
