 # AI Code Audit CLI
 
-A CLI tool that validates AI-generated code for common issues, anti-patterns, and security vulnerabilities. It analyzes code produced by AI assistants (like GitHub Copilot, Claude Code, etc.) and generates quality reports with improvement suggestions and confidence scores.
+A CLI tool for scanning code and auditing for issues using AI.
-
-![CI Status](https://7000pct.gitea.bloupla.net/api/badges/7000pctAUTO/ai-code-audit-cli/status.svg)
-![Python Version](https://img.shields.io/badge/python-3.9%2B-blue)
-![License](https://img.shields.io/badge/License-MIT-green)
 
 ## Features
 
-- **Security Vulnerability Detection**: Detect hardcoded secrets, SQL injection risks, command injection, and other security issues
+- Scan Python, JavaScript, and TypeScript files
-- **Code Smell Detection**: Identify code smells like unused imports, mutable defaults, complex functions, and poor error handling
+- Multiple output formats (terminal, JSON, markdown)
-- **Multi-language Support**: Analyze Python, JavaScript, and TypeScript code
+- Severity-based filtering
-- **Confidence Scoring**: Get a 0-100 score reflecting code quality and security posture
+- Confidence scoring for results
-- **Multiple Output Formats**: Terminal output with Rich formatting, JSON, and Markdown export options
-- **Severity-based Filtering**: Filter issues by severity level (critical, high, medium, low, info)
 
 ## Installation
 
-### From Source
-
-```bash
-git clone https://7000pct.gitea.bloupla.net/7000pctAUTO/ai-code-audit-cli.git
-cd ai-code-audit-cli
-pip install -e .
-```
-
-### Using pip
-
 ```bash
 pip install ai-code-audit-cli
 ```
 
-## Quick Start
-
-```bash
-# Audit a single file
-audit scan path/to/file.py
-
-# Audit a directory recursively
-audit scan path/to/project/
-
-# Audit with JSON output
-audit scan path/to/code/ --format json
-
-# Audit with verbose output
-audit scan path/to/code/ --verbose
-
-# Filter by language
-audit scan path/to/code/ --language python
-
-# Filter by severity
-audit scan path/to/code/ --severity high
-```
-
 ## Usage
 
-### Basic Scanning
-
 ```bash
-# Scan a Python file
+audit scan <path> [--format terminal|json|markdown] [--severity low|medium|high|critical]
-audit scan my_script.py
-
-# Scan a JavaScript file
-audit scan index.js
-
-# Scan a TypeScript file
-audit scan app.ts
-
-# Scan a directory
-audit scan src/
-```
-
-### Output Options
-
-```bash
-# Rich terminal output (default)
-audit scan path/to/code/
-
-# JSON output for CI/CD
-audit scan path/to/code/ --format json
-
-# Markdown report
-audit scan path/to/code/ --format markdown
-
-# Quiet mode (minimal output)
-audit scan path/to/code/ --quiet
-```
-
-### Filtering Options
-
-```bash
-# Only scan Python files
-audit scan path/to/code/ --language python
-
-# Only show critical and high severity issues
-audit scan path/to/code/ --severity critical high
-
-# Skip color output
-audit scan path/to/code/ --no-color
-
-# Verbose output with more details
-audit scan path/to/code/ --verbose
 ```
 
 ## Configuration
 
-### Audit Configuration File
+Create a `.env` file with:
-
-Create an `audit.toml` file in your project root:
-
-```toml
-[severity]
-critical = true
-high = true
-medium = true
-low = true
-info = false
-
-[languages]
-python = true
-javascript = true
-typescript = true
-
-[scanners]
-bandit = true
-ruff = true
-tree_sitter = true
-
-[confidence]
-min_score = 70
 ```
-
+OPENAI_API_KEY=your_api_key
-### PyProject.toml Integration
-
-The tool automatically reads Ruff configuration from your `pyproject.toml`:
-
-```toml
-[tool.ruff]
-line-length = 88
-select = ["E", "F", "W", "C90", "I", "N", "UP", "B", "SIM"]
-ignore = ["E501"]
-
-[tool.ruff.per-file-ignores]
-"__init__.py" = ["F401"]
-```
-
-## Output Formats
-
-### Terminal Output
-
-The default terminal output uses Rich formatting to display:
-
-```

-## Summary
-
-| Metric | Value |
-|--------|-------|
-| Files Scanned | 15 |
-| Issues Found | 23 |
-| Confidence Score | 78 |
-
-## Issues
-
-### Critical
-
-| File | Line | Issue |
-|------|------|-------|
-| src/auth.py | 42 | Possible hardcoded password |
-```
-
-## Confidence Score
-
-The confidence score (0-100) reflects the overall quality and security posture of the analyzed code:
-
-- **90-100**: Excellent - Code is well-structured and secure
-- **70-89**: Good - Minor issues found, generally safe to use
-- **50-69**: Moderate - Several issues, review recommended
-- **30-49**: Poor - Significant issues, refactoring advised
-- **0-29**: Critical - Major problems, do not deploy
-
-### Score Calculation
-
-The score is calculated based on:
-
-1. **Security Issues (40% weight)**: Critical issues have highest impact
-2. **Code Smells (30% weight)**: Anti-patterns and poor practices
-3. **Complexity (20% weight)**: Function complexity and file size
-4. **Error Handling (10% weight)**: Missing exception handling
-
-## Supported Languages
-
-| Language | Security Scanning | Linting | Pattern Detection |
-|----------|------------------|---------|-------------------|
-| Python | ✅ Bandit | ✅ Ruff | ✅ Tree-sitter |
-| JavaScript | ⚠️ Basic | ✅ Ruff | ✅ Tree-sitter |
-| TypeScript | ⚠️ Basic | ✅ Ruff | ✅ Tree-sitter |

-scanner.print_report(results)
-```
-

-
-```python
-from src.core.config import AuditConfig
-
-config = AuditConfig(
-    severity_filter={"critical", "high", "medium"},
