# Introduction

**Blame** is an autonomous AI code review agent designed to act as a senior staff engineer on every pull request.

Unlike conventional linters or superficial diff checkers that evaluate files in isolation, Blame uses **Tree-Sitter AST parsing and semantic repo mapping** to understand your entire system architecture—identifying how a 2-line change in one file impacts distant endpoints, database queries, and state management.

## How It Works

    A[1. Connect Repo] --> B[2. Index Architecture]
    B --> C[3. Auto-Review PRs]
    C --> D[4. Suggest Fixes]
    D --> E[5. Team Memory & Learning]
```

Install the [Blame GitHub App](/integrations/github) and enable your repositories. Blame immediately parses your AST, maps symbol dependencies, and constructs a semantic index of your codebase using a GraphRAG architecture.

On every opened PR or new commit, Blame runs deep reasoning over the diff against full repository context. Actionable findings, security warnings, and inline code suggestions are posted directly as PR review comments in under 60 seconds.

Ask questions directly in your PR comments or open the [AI Chat](/features/ai-chat) inside the Blame dashboard to debug regressions or write tests.

Define custom repo rules, style guides, and review guidelines. Blame’s continuous memory engine adapts to your team’s feedback and PR resolutions—permanently suppressing noise and honing review precision.
