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 →

Omitted options take the web app's defaults. instructions is optional for audio, video, slide_deck and quiz, required for report, mind_map, flashcards and data_table, and refused by infographic and interactive_report (each as captured). video.generate_later asks for deferred generation (cinematic format only). report needs report.title and report.description plus instructions as the prompt (suggest surface report returns ready-made triples). Checks the account quota first and returns a QUOTA error when it is used up. Artifacts are built from the notebook's sources only, not notes (the web app can add notes; that is not supported).
