## What it is
PSScriptAnalyzer is a static code checker (linter and formatter) for PowerShell scripts and modules, maintained by the PowerShell team. It applies built-in and custom rules based on PowerShell best practices and reports diagnostics with suggested fixes.

## Use cases
- lint powershell scripts for best practice violations
- format powershell code automatically
- check powershell modules for uninitialized variables
- detect unsafe use of Invoke-Expression in scripts
- enforce powershell code style in CI pipelines
- write custom static analysis rules for powershell

## When to choose
- you write or maintain PowerShell scripts or modules and want automated quality checks
- you need consistent PowerShell formatting across a team or codebase
- you want to catch common PowerShell defects before shipping

## When to avoid
- you need linting for languages other than PowerShell
- you need dynamic runtime analysis or profiling rather than static checks

## Facets
- artifact type: library
- maturity: active
- function: linter, formatter, developer-tools
- domain: developer-tools
- platform: windows, cross-platform, cli
- tags: powershell, static-analysis, code-quality, best-practices, powershell-gallery, command-line, automation, linux, macos
