## What it is
Capslock is a capability analysis CLI for Go packages that classifies which privileged operations a package can access via transitive calls to the standard library. It helps surface the permissions of third-party dependencies to support supply chain security reviews.

## Use cases
- audit which privileged operations my Go dependencies can access
- detect unexpected capability changes in third-party packages
- direct security reviews toward the most privileged code paths
- apply least-privilege analysis to Go packages before trusting them
- identify the purpose of an unknown Go package from its capabilities

## When to choose
- you maintain Go code and want to vet third-party dependencies for excessive privileges
- you run supply chain security reviews and need capability signals beyond CVE scanning
- you want to alert on capability changes in dependencies over time

## When to avoid
- your project is not written in Go
- you need dynamic runtime analysis or vulnerability/CVE scanning rather than static capability classification
- you need analysis of non-standard-library privileged operations outside Capslock's supported set
