Where it applies
Jobs this tool actually does, and the surface each one is exercised on.
Run feature flags with no vendor and no account, from a file in the repository.

Notable for agent work because it runs entirely offline — flags become testable configuration rather than a hosted dependency.
Gate a risky change behind a flag so it can be turned off without a redeploy.
