ragcheck-cli 0.2.8

Lighthouse for RAG systems - diagnose and fix your retrieval pipeline

ragcheck - Lighthouse for RAG Systems

One command to diagnose your RAG pipeline and get actionable fixes.

pip install ragcheck-cli
ragcheck init
ragcheck run --docs ./data --query "What is Article 370?"

What is ragcheck?

ragcheck is a lightweight, one-command diagnostic CLI that generates a beautiful, shareable HTML report analyzing why your RAG system fails and how to fix it.

Think of it as Lighthouse for RAG systems — just like Lighthouse audits web pages, ragcheck audits your retrieval pipeline.

Features

• Auto-Generated Test Suite - 50 synthetic questions from your documents
• Chunk Visualizer - See exactly where your chunking breaks
• Retrieval Heatmap - Identify dead chunks and dominant chunks
• Failure Classification - Know WHY your RAG fails, not just THAT it fails
• Actionable Recommendations - Specific fixes with predicted impact
• CI/CD Integration - Fail builds when RAG quality regresses

Quick Start

Installation

pip install ragcheck-cli

Or with uv:

uv tool install ragcheck-cli

Initialize

ragcheck init

Creates a ragcheck.yaml config file in your project.

Run Analysis

ragcheck run --docs ./data --query "Your test query"

Generates ragcheck_report.html with:

• Scorecards (retrieval accuracy, faithfulness)
• Chunk boundary visualization
• Retrieval heatmap
• Failure mode classification
• Before/after score predictions

CI Mode

ragcheck run --docs ./data --ci --min-score 0.80

Returns exit code 0/1. Use in GitHub Actions to fail builds on quality regression.
