aula_list_courses

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

With no annotations, the description carries the full burden. It discloses the scope (user's enrolled courses) which is useful behavioral context, but it does not state whether results are paginated, cached, ordered, or what happens if the user has no enrollments. That leaves notable behavioral gaps for a list operation.

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?

A single, front-loaded sentence with zero waste. It states the action and scope immediately and does not pad with redundant or vague phrasing.

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?

For a no-parameter, no-annotation, no-output-schema list tool, the description is minimally adequate but incomplete. It does not mention ordering, pagination, empty-state behavior, or the response shape, which an agent might need in the absence of structured metadata.

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?

There are zero parameters, so the baseline is 4. The description adds no parameter detail because there is none to add, and the tool requires no inputs, which is consistent.

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?

States a specific verb ('Lista') and resource ('los cursos/materias'), plus the scope ('en los que está inscripto el usuario en el aula virtual'). It is clearly distinguished from the sibling aula_get_site_info, which presumably returns site metadata rather than enrolled 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?

No explicit when-to-use guidance or alternatives are given. The description implies it is for retrieving the user's own course enrollment, but it does not say when to choose this over aula_get_site_info or any other retrieval method.

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