Is this your server? Own a server? ToolFit hosted watch re-checks it every 24 h ($0.25 per 30 days) or 6 h ($0.60) and sends you an HMAC-signed webhook when its tools or grade change: POST https://api.youraitools.co/toolfit/v1/watch. To opt out, see About & opt-out.

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 one runs attacker code. You cannot tell the difference by looking at the name, which is why this c params: command* |
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 the registry. Do not proceed
phantom - does not exist AND models repeatedly inve params: identifiers* |
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. params: content*, filename* |
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 worth monitoring. Delivered by signed webhook to a URL you supply. params: callbackUrl*, identifiers* |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
