TDQS

A4/5.0

Scored across 20 tools

Disambiguation5/5

Each tool targets a distinct resource or action: account creation vs verification, upload steps vs metadata editing, asset search vs pack search, and list vs get operations are clearly separated. No two tools appear to overlap in purpose.

Naming Consistency5/5

All tools follow a consistent verb_noun pattern (create_, get_, list_, search_, submit_, update_, verify_, finalize_, my_) with snake_case throughout. The 'my_' prefix is a minor stylistic deviation but predictable and used consistently for user-specific resources.

Tool Count4/5

At 20 tools, the set is slightly heavy but each tool serves a distinct need across accounts, uploads, assets, packs, demos, and metadata. The breadth of functionality justifies the count, though it exceeds the typical 3-15 range.

Completeness5/5

The surface covers the full lifecycle: account creation and verification, two upload paths (direct and URL), asset retrieval/search/update, pack submission/retrieval/search, demo browsing, and auxiliary metadata lists. Missing delete operations appear intentional to prevent destructive actions, and all read paths provide direct CDN URLs.

Available Tools

create_accountCreate accountAInspect

Create a contributor account for the user. Needs only a username and email. There is no password anywhere in this product, so never ask the user for one. A 6-digit code is emailed to them; ask the user to read it to you, then call verify_account to receive their API key. Only do this with the user’s explicit consent.

descriptionNoMarkdown: scale, pivot, what is included
submit_packPropose a packAInspect

Group 2–50 of the user’s own uploads (any that are processing, pending or published) into a pack proposal. Upload the models first with finalize_upload or submit_asset_from_url, then pass their slugs here. Each model is still reviewed on its own; a person approves the pack as a whole, which publishes any members still pending and creates the pack page. Nothing goes live until then. The user is emailed the outcome.

NameRequiredDescriptionDefault
titleYes
assetsYes
summaryYes
descriptionNo
update_assetUpdate assetAInspect

Edit the metadata of one of the user’s own assets. The uploaded GLB can never be changed. Editing an asset that is already published does not change it: the proposal goes to the review queue and the live version keeps serving until a person approves it.
