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 →
bulk_delete_assets ~54
Permanently delete 1–100 explicit asset IDs. Inspect each result: a successful HTTP request can contain failed items. Scoped keys require delete permission. No query-based deletion or undo.

| asset_ids | array | yes | – |
No output schema declared.
No examples provided.
delete_asset ~62
Permanently delete one explicit asset ID. Irreversible; no restore or cancellation. Scoped keys need explicit delete permission. Acceptance starts background cleanup; cached/offline copies may remain.
