list_students

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

The annotations already communicate readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is established. The description adds no behavioral context beyond that, but it also does not contradict the annotations.

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 concise to the point of under-specification. It is a short phrase that merely repeats the tool name, providing no front-loaded useful elaboration about behavior, return values, or selection criteria.

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 simple parameter set, strong annotations, and presence of an output schema, the tool is minimally callable. However, the description itself is too sparse to fully contextualize the resource or its relationship to the many sibling list tools, leaving selection ambiguity.

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 100% for the two parameters (limit and offset), and both have clear descriptions. The tool description adds no parameter-level meaning, but the baseline of 3 is appropriate because the schema already carries the full burden.

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 Students' is essentially a restatement of the tool name, providing no additional specificity about scope, filtering, or what a 'student' record includes. It also does nothing to distinguish this tool from siblings like list_student_groups, list_lesson_participants, or list_students-related listing tools.

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 when-to-use guidance is given. The description does not mention when to prefer list_students over other list_* siblings, nor any exclusions or context such as 'list all students in the organization'.

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