check_package
Check a single package name against the real npm or PyPI registry
scan_directory
Auto-detect and check both npm and pip manifests (package.json, requirements.txt, pyproject.toml) in a directory against their real registries
scan_npm
Check every dependency declared in a package.json (dependencies, devDependencies, peerDependencies, optionalDependencies) against the real npm registry -- flags any package name that doesn't exist at all (a likely LLM-hallucinated dependency an attacker may have pre-registered, i.e. 'slopsquatting'), and separately notes any that exist but were only first published very recently.
scan_pip
Check every dependency declared in requirements.txt or pyproject.toml against the real PyPI registry -- flags any package name that doesn't exist at all (a likely LLM-hallucinated dependency an attacker may have pre-registered), and separately notes any that exist but were only first published very recently.
