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 →
ask_humans Ask verified humans ~595
Send a decision to ID verified people before you act on it. Several people answer independently, each confirmed with Face ID, and you get back the consensus answer and how strongly they agreed. Use it for judgment calls where being wrong is costly: evals of AI output, tone and intent, whether two things match, moderation edge cases. Send refunds, payments and other money calls with route team. Write the question so a stranger can answer it from the context alone, and never include secrets or more personal data than the decision needs. Live keys use prepaid credit at $0.20 per answer (clips cost more by length), or $0.05 per internal vote with route team; test keys are free and simulated.
