list_class_students

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

No annotations are provided, so the description carries the burden. It implies a read-only operation via 'List', but does not explicitly state safety or return behavior. For a simple listing tool, the risk is low, yet important details like pagination or error conditions are absent. Adequate but not thorough.

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 with no filler. The purpose is front-loaded, and the parameter explanation is concise. It's appropriately sized for a simple read operation, earning a high score for efficiency and clarity.

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?

The tool is simple with one parameter and an output schema exists, which covers return structure. The description covers the purpose and parameter source, but does not mention any limitations or edge cases. Given the low complexity, it is reasonably complete, though it could note the distinction from list_students.

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%, so the description must compensate. It does by explaining the parameter: 'Class/section ID (from list_classes)', which adds meaning about its origin and type. This is helpful and reduces ambiguity, though it lacks examples or validation details.

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 states the tool lists students enrolled in one class, with a specific verb and resource. The scope 'in one class' helps distinguish it from list_students, though it doesn't explicitly name alternatives. It's clear but could be sharper on differentiation.

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 gives a parameter hint: 'from list_classes', which indicates where to obtain the section_id. However, it does not explicitly state when to use this tool versus list_students or other class-related tools. Some context is provided but no exclusions or alternative selection criteria.

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