pexels_collection_media

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

No annotations are provided, and the description only states the action without revealing any behavioral details such as pagination, type filtering, sort options, default behavior, or error handling. This leaves the agent without information about how the tool behaves beyond its basic purpose.

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?

The description is a single, direct sentence with no redundant words, making it concise and easy to parse.

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?

With five parameters and no output schema or annotations, the one-sentence description is insufficient. It fails to clarify how optional parameters like type or sort function, what the response structure looks like, or how pagination works, leaving significant gaps for correct invocation.

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 description coverage is 0%, and the description only references 'id' while ignoring page, sort, type, and per_page. The agent cannot infer the meaning or effect of these parameters from the description, which is especially problematic given enums exist for sort and type.

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?

The description uses the specific verb 'Retrieve' and names the resource 'photos and videos within a Pexels collection', clearly distinguishing it from sibling tools like pexels_search_photos or pexels_get_photo by focusing on collection membership.

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?

The description implies usage when a collection ID is known and you want its media, but provides no explicit guidance on when to prefer this over alternatives or any exclusions. It does not mention that collection metadata is available via sibling tools like pexels_my_collections.

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