list-students

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

The annotation already provides readOnlyHint=true. The description adds little beyond that: 'complete list' is a vague scope qualifier, and there is no mention of pagination, response format, or privacy defaults. These behaviors are only implicit in the schema, not disclosed in the description.

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, concise sentence that front-loads the verb and clearly states the purpose. There is no redundant information or fluff.

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 read-only nature and rich schema with 100% parameter coverage, the description is mostly sufficient for an agent to invoke the tool. However, it lacks explicit mention of the return structure or any usage caveats, though these are not critical for such a straightforward list operation.

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%, so the baseline is 3. The description adds no extra meaning beyond the schema; it only implicitly references courseId via 'a specific course' and does not elaborate on the anonymous or includeEmail parameters.

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 uses the verb 'Get' with a specific resource ('complete list of all students') and scope ('enrolled in a specific course'). It distinguishes the tool from siblings that operate on modules, assignments, or courses.

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 offers no guidance on when to use this tool versus alternatives, no prerequisites, and no exclusions. It simply restates the function without contextual advice, such as recommended use cases 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.
