Module language_detector 

Language and Stack Detection Module

Detects the primary technology stack of a repository by analyzing file extensions, configuration files, and common patterns. This enables language-specific review guidance without requiring an LLM.

The detection is fast (< 100ms typically) and uses heuristics based on:

• File extension counts
• Signature files (Cargo.toml, package.json, etc.)
• Framework indicators in config files

Module Structure

• [extensions] - Extension to language mapping
• [signatures] - Signature file detection for frameworks and package managers
• [scanner] - File system scanning utilities
