## Tools (as reported by the server, not verified)

- `hallux\_check\_command`: Call this BEFORE running any command that installs a dependency: npm, yarn, pnpm, bun, pip, uv, poetry, pipx, cargo, go get, dotnet add package, nuget. Language models invent plausible package names that have never existed, and attackers register those names because they can predict them. Installing
- `hallux\_check`: Does this identifier actually exist? Call before acting on any name you recalled rather than read: a package to install, a module to import, a DOI to cite. Returns one of: exists, deprecated, absent, phantom, squat, unknown. exists - proceed deprecated - proceed, but use \`successor\` absent - not in
- `hallux\_check\_manifest`: Call this after writing or editing a dependency file, and before committing it. Supported: package.json, requirements.txt, pyproject.toml, Cargo.toml, go.mod. Checks every dependency in one pass, including dev and optional groups, which is where an invented name usually arrives.
- `hallux\_watch`: Register identifiers for notification when their verdict changes. The transition that matters is phantom to squat: a name models invent that somebody then registers. Use this for a dependency that came back \`absent\` or \`phantom\` and that the user intends to use anyway, or for a set of dependencies w
