valknut-rs

High-Performance Code Analysis for Modern Development Teams

Valknut provides comprehensive code analysis through advanced statistical algorithms and graph-based analysis. While other tools count lines and check syntax, Valknut analyzes code complexity, identifies architectural debt, and provides actionable refactoring recommendations with quantified impact. Built in Rust for production speed and integrated with CI/CD for automated quality gates.

Stop guessing what needs refactoring. Get data-driven insights that improve code maintainability.

Quickstart

Installation

Via Homebrew (macOS)

brew tap sibyllinesoft/valknut
brew install valknut

Via Cargo (recommended)

cargo install valknut-rs

Build from Source (requires Rust 1.70+)

git clone https://github.com/sibyllinesoft/valknut
cd valknut
cargo build --release

Get Results in 30 Seconds

# Analyze your codebase and get actionable insights
./target/release/valknut analyze ./src

# Generate team-friendly HTML report
valknut analyze --format html --out reports/ ./src

# Set up CI/CD quality gates (fails build if thresholds exceeded)
valknut analyze --quality-gate --max-complexity 75 --min-health 60 ./src

That's it. Valknut will analyze your code structure, complexity, naming quality, and technical debt, then provide prioritized recommendations for improvement.

What Makes Valknut Different

Statistical Code Analysis

Traditional tools analyze syntax. Valknut analyzes patterns and complexity. It uses advanced statistical algorithms to evaluate code structure, identify complexity hotspots, and detect architectural anti-patterns that impact maintainability.

Production-Ready Performance

Built in Rust with SIMD optimizations, Valknut analyzes large codebases in seconds, not minutes. Designed for enterprise-scale projects with 100k+ files while maintaining sub-linear memory usage.

Quantified Technical Debt

Get concrete metrics on technical debt with prioritized recommendations. Know exactly which refactoring will provide the highest impact and where to focus your team's effort.

Zero-Configuration CI/CD Integration

Drop into any CI/CD pipeline with quality gates that fail builds when code quality degrades. No complex setup required.

Multi-Language Support

Comprehensive structural analysis for Python, TypeScript, JavaScript, Rust, Go, and more. Each language parser understands syntactic patterns and provides language-specific complexity insights.

Core Capabilities

Structure Analysis: Identifies architectural anti-patterns and organizational debt that impacts maintainability

Complexity Intelligence: Goes beyond cyclomatic complexity to measure cognitive load and refactoring priority

Code Quality Analysis: Statistical evaluation of code patterns and structural complexity

Refactoring Recommendations: Actionable insights with quantified impact scoring and effort estimation

Dependency Health: Detects circular dependencies, architectural chokepoints, and coupling hotspots

Technical Debt Quantification: Measurable debt metrics with ROI analysis for refactoring efforts

Configuration

Quick Setup

Quality Gates for CI/CD

Configure automatic build failures when quality thresholds are exceeded:

quality_gates:
  enabled: true
  max_complexity: 75        # Fail if complexity score exceeds 75
  min_health: 60           # Fail if health score drops below 60
  max_debt: 30             # Fail if technical debt exceeds 30%
  max_issues: 50           # Fail if more than 50 total issues
  max_critical: 0          # Fail on any critical issues

Language-Specific Configuration

languages:
  python:
    enabled: true
    complexity_threshold: 10.0
    file_extensions: [".py", ".pyi"]
  typescript:
    enabled: true
    complexity_threshold: 10.0
    file_extensions: [".ts", ".tsx"]

Advanced Options

analysis:
  enabled: true
  complexity_threshold: 10.0
  min_confidence: 0.65     # Analysis confidence threshold
  include_test_files: true # Include test files in analysis
