Find media

mediaList
Read-onlyIdempotent

Returns ready owned source, edited and converted media with an optional all, image or video filter. Omitting the filter returns the established JPEG/PNG image list. Upload tools add files to the same library. Search or the bounded scan can return fewer than limit items; continue with cursor until done is true.

  2. First observed

TDQS

A3.8/5.0
Behavior4/5

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

Annotations already declare read-only, idempotent and non-destructive. The description adds genuinely non-obvious behavior: search or bounded scans may return fewer than 'limit' items and you must continue with cursor until 'done' is true. That goes beyond structured fields.

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

Conciseness4/5

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

Three front-loaded sentences with essentially no waste; the core behavior and pagination caveat come first. Slightly dense phrasing ('ready owned source, edited and converted media') but still earned.

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

Completeness4/5

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

An output schema exists, so return shape needn't be restated, and the description still references the 'done' flag for completeness. Ordering of results and the meaning of 'ready' remain unstated, a minor gap for a list tool.

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?

Schema coverage is only 25%, so the description must carry weight. It explains the default behavior of 'kind' when omitted and clarifies that 'cursor' drives a continuation loop and 'search' can under-return, adding meaning beyond the bare schema properties.

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

Purpose4/5

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

States a specific verb and resource: 'Returns ready owned source, edited and converted media'. It implicitly distinguishes itself from mediaGet/upload tools by noting uploads feed the same library, though it never names a sibling directly.

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

Usage Guidelines3/5

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

Explains filter invocation ('Omitting the filter returns the established JPEG/PNG image list') and pagination continuation, which is useful operator guidance. However, it never states when to prefer this over mediaGet or the scan/search alternatives, leaving selection to inference.

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