The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
audit_tokens ~111
Audit a live URL's design-system token usage. Returns a 0-100 token-health score plus findings (inconsistent font sizes, text colors, spacing, font families, border radii) with severity and evidence.
