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 →

Never read, quote, or pass the secret to this tool. Reuse the same requestId and metadata for retries. Requires clipboard saving and agent creation enabled in the dashboard.
