## What it is
Parliament is a Python library and CLI tool that lints AWS IAM policies, detecting malformed JSON, invalid actions and resources, type mismatches, and bad policy patterns. It can be used programmatically as a library or from the command line against files, directories, or AWS authorization details exports.

## Use cases
- lint aws iam policies for errors
- find incorrect resources or conditions in iam policy actions
- audit aws managed policies for bad patterns
- validate iam policy json before deployment
- integrate iam policy linting into ci pipeline
- analyze get-account-authorization-details output for policy issues

## When to choose
- you need programmatic IAM policy analysis as a Python library
- you want CLI linting of IAM policy files or directories
- you need configurable finding severities via override config files

## When to avoid
- you need full cloud security posture management beyond IAM policies
- you work with non-AWS cloud IAM systems
- you need runtime enforcement rather than static linting

## Facets
- artifact type: library
- maturity: active
- function: linter, security, cli, developer-tools
- domain: security, cloud-computing, developer-tools
- platform: python, cli, cross-platform
