Search stock media

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

No annotations provided; description carries full burden. Discloses return content (URLs, metadata) but omits crucial behavioral details: read-only status, authentication requirements, rate limits, pagination behavior, or error scenarios.

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

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

Two sentences, front-loaded with purpose and key output details. No redundant or off-topic content.

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

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

Given 5 parameters, no output schema, and no annotations, the description is too brief. Lacks explanation of pagination, required parameters, defaults, and domain-specific terms like 'Zvid payloads'. Users need additional context for effective use.

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

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

Schema coverage is 0%. Description adds meaning only for 'type' parameter (image/video/GIF/music) and mentions providers generally, but fails to explain 'query', 'page', 'perPage', or the 'provider' enum values beyond listing them. Leaves significant gaps for effective usage.

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

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

Clearly states the tool searches stock media (image, video, GIF, music) and specifies what results contain (preview/full-quality URLs, dimensions/duration, attribution). Distinct from sibling tools like list_stock_providers or search_creative_library.

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

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

No explicit guidance on when to use this tool versus alternatives (e.g., search_creative_library). Implies usage for stock media in Zvid payloads but lacks exclusions or context for choosing among sibling tools.

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