marketplace_info

Shows which 3D model marketplaces are connected and their available capabilities, such as search and download support.

Instructions

Show which 3D model marketplaces are connected and available.

Returns the list of connected marketplace sources and their
capabilities (search, download support, etc.).  Configure
marketplaces via environment variables.

**See also:** ``marketplace_status`` for per-credential diagnostics,
or ``marketplace_diagnostics`` for live connectivity probes.

**Safety note:** Community-uploaded models are unverified.  Always
review model dimensions and preview prints before starting.
Proven, popular models with high download counts are safer choices
than untested uploads.

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It discloses that the operation is a read (Show/Returns), mentions configuration via environment variables, and adds a safety note about unverified community-uploaded models. This provides good context beyond a simple listing, though no details on rate limits or permissions are given.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise at four sentences, with front-loaded purpose, clear structure, and no superfluous content. The safety note is separated and relevant.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (no parameters, no output schema), the description fully covers its purpose, configuration, alternatives, and safety considerations. It is complete and actionable for an AI agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, so the input schema is trivially complete (schema coverage 100%). The description does not need to add parameter details. The baseline for 0 parameters is 4, and the description adds no unnecessary information.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description begins with a clear verb-resource pair: 'Show which 3D model marketplaces are connected and available.' It differentiates from sibling tools marketplace_status and marketplace_diagnostics by referencing them in the 'See also' section.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Description explicitly states when to use this tool (to list connected marketplaces and their capabilities) and gives alternatives for more specific diagnostics: marketplace_status for per-credential diagnostics and marketplace_diagnostics for live connectivity probes.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
