list_model_servers

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

With no annotations, the description must convey behavioral traits. It states the tool lists resources but does not disclose whether it is read-only, any permissions required, pagination behavior, or output limits. The presence of an output schema is known but not described.

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 redundancy. However, it is too brief to convey necessary details, sacrificing completeness for brevity.

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?

Despite the existence of an output schema (not visible), the description fails to cover key aspects: parameter usage, listing behavior scope, and any constraints. With 0% schema coverage, the description is insufficient for the agent to understand the tool's full functionality.

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 input schema has two parameters (cluster, namespace) with 0% schema description coverage. The description does not explain these parameters or how they affect results. The mention of 'scope, formats, multi-model, and age' likely refers to filtering or output fields, but it is unrelated to the actual parameters, leaving the agent without parameter guidance.

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 clearly identifies the tool lists 'ServingRuntimes and ClusterServingRuntimes', specifying the resource types. It distinguishes from sibling tools like list_data_volumes or list_model_registries. However, the phrase 'with scope, formats, multi-model, and age' is ambiguous—it may refer to filtering options but is not explicit.

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 (e.g., list_model_registries). There is no mention of prerequisites, contexts, or 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.
