alphaportal_list_students

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

With readOnlyHint=true and openWorldHint=true already declaring the safety and scope profile, the description adds value by enumerating the fields returned (grade, school, transportation flags) — useful since no output schema exists. It also implies the session/auth requirement via 'signed-in account'. It says nothing about empty results or data freshness.

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 tight sentences with no filler, and the scope statement plus the routing cue are front-loaded. Every phrase earns its place.

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 zero-parameter, read-only list call with no output schema, the description covers scope, returned content, and usage entry point — enough to invoke it confidently. Minor gaps (empty-list behavior, whether the account could have zero students) are negligible.

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 tool takes zero parameters, so per the baseline there are no argument semantics to explain. There is no risk of the description misleading about inputs.

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 and resource (list the students/children on the signed-in account) and even previews the payload ('grade, school, and transportation flags'). It is clearly distinguished from the singular alphaportal_get_student, though that sibling is never named explicitly.

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?

'Start here to get each studentId' gives a clear entry-point cue that this is the prerequisite call for ID-consuming siblings like get_student and get_student_stops. It does not name those alternatives or state any exclusions, so it stops short of full when/when-not guidance.

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