Repokid is an AWS IAM permission management tool that automatically removes unused service permissions from IAM role inline policies. The tool integrates with Access Advisor through Aardvark to analyze service usage patterns and identify permissions that grant access to services that are not being utilized. It operates by scanning IAM roles within an AWS account and removing permissions for services that have not been accessed. Repokid requires a DynamoDB table for storing role information and uses specific table structures with primary keys and global secondary indexes for efficient data organization. The tool supports both cloud-based and local development environments, with Docker Compose available for local DynamoDB instances. The system requires appropriate IAM permissions to function across AWS accounts and can be configured through a JSON configuration file. It provides a systematic approach to implementing the principle of least privilege by automatically pruning unnecessary permissions from IAM roles.
