# Automated Refactoring Patterns

Common code patterns that can be safely automated and how to implement them with Autohand.

**Tip:** These guides demonstrate a modified version of the Autohand CLI built for Enterprise customers. Feel free to [fork the Autohand CLI](https://github.com/autohand/autohand-cli) to add support for these features in your own environment.

## Understanding technical debt

Technical debt accumulates when teams prioritize speed over code quality. Autohand helps identify and resolve common debt patterns systematically.

-   Code duplication across modules
-   Outdated dependencies with security vulnerabilities
-   Complex functions exceeding maintainability thresholds
-   Missing or outdated documentation

## Detecting technical debt

Run a debt analysis to identify problem areas:

``` bash
# Full codebase analysis
autohand debt analyze --report debt-report.html

# Focus on specific patterns
autohand debt analyze --patterns duplication,complexity

# Integrate with CI
autohand debt check --threshold moderate --fail-on-increase
```

The report categorizes issues by severity and provides estimated remediation effort.

## Eliminating duplication

Autohand identifies and consolidates duplicate code:

``` bash
# Find duplicate patterns
autohand refactor find-duplicates --min-lines 10

# Extract common functions
autohand refactor extract-common \
  --source src/modules/ \
  --target src/shared/

# Preview changes
autohand refactor extract-common --dry-run
```

## Reducing complexity

Break down complex functions into maintainable units:

``` bash
# Find functions exceeding complexity threshold
autohand refactor complexity --threshold 15

# Suggest decomposition
autohand refactor simplify --file src/handlers/payment.ts

# Apply with review
autohand refactor simplify --interactive
```

Autohand suggests logical boundaries for function extraction based on data flow analysis.

## Dependency management

Keep dependencies updated and secure:

``` bash
# Audit dependencies
autohand deps audit

# Update with compatibility checks
autohand deps update --safe

# Fix security vulnerabilities
autohand deps fix --severity high

# Generate upgrade plan
autohand deps plan --target latest
```

## Continuous debt reduction

Integrate debt reduction into your workflow:

``` yaml
# .github/workflows/debt-reduction.yml
name: Technical Debt Check
on: [pull_request]

jobs:
  debt-check:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Run debt analysis
        run: |
          autohand debt check \
            --baseline main \
            --fail-on-increase
```

This prevents new debt from entering the codebase while allowing gradual improvement.

## Prioritization framework

Focus on high-impact improvements:

-   **Security**: Fix vulnerabilities immediately
-   **Stability**: Address code causing production issues
-   **Velocity**: Refactor areas slowing development
-   **Maintainability**: Improve code for long-term health
