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

The readOnlyHint annotation already indicates this is a safe read operation, and the description adds that it returns a 'linkset for agent discovery', which is mildly informative. However, it does not elaborate on what the linkset contains or whether any network or authentication behavior is relevant, so the description adds limited value beyond the annotation.

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 sentence with no filler, clearly stating the action and object. It is appropriately sized for a zero-parameter tool and front-loads the core message.

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 tool's simplicity (no parameters, read-only, straightforward return type), the description is largely complete: it states what is returned and for what purpose. The main gap is not explaining the 'catalog linkset' in more detail or how it relates to sibling discovery tools, but for a simple tool with annotations, the information provided is sufficient.

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 tool has zero parameters, so the baseline is 4. The description naturally does not need to explain parameter meanings, and the empty schema is sufficient.

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 a specific verb 'Return' and identifies the resource as 'Quiz.Video API catalog linkset', making the tool's basic purpose clear. However, it does not explicitly distinguish this from sibling tools like get_llms_txt or get_openapi_spec, which may also serve discovery purposes.

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 guidance is provided on when to use this tool versus alternatives. The phrase 'for agent discovery' implies a use case but does not clarify how this differs from sibling tools like get_llms_txt or get_openapi_spec, nor does it state when not to use it.

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