jio_list_photos

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

There are no annotations, so the description must carry the full burden of behavioral disclosure. The word 'List' implies a read-only operation, which gives a basic safety hint, but it does not disclose pagination behavior, input parameter effects, output format, or any side effects.

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 extremely short, bordering on under-specification. While front-loaded and free of fluff, it lacks essential details, making it more of a placeholder than a concise explanation.

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 the absence of annotations, output schema, and parameter descriptions, this minimal description is grossly insufficient. The agent cannot understand pagination, how to use optional parameters, or what the response contains.

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?

The schema has 0% description coverage, and the description does not explain any of the three parameters (limit, allPages, nextLink). There is no added meaning beyond what the raw schema properties show, leaving the agent to guess their purpose.

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 'List backed-up photos' clearly identifies the action (List) and the resource (backed-up photos), distinguishing it from sibling tools that list videos, documents, or albums. This is a specific and unambiguous purpose statement, comparable to the high-scoring example 'List ALL calls in date range'.

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 provides no guidance on when to use this tool versus alternatives like jio_list_files or jio_list_videos. It does not mention exclusions, prerequisites, or scenarios where it is preferred.

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