attendance_students

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

The description accurately conveys that this is a read-only listing operation and includes guardian data, which is useful. However, with no annotations, it does not disclose response format, pagination behavior, or the sensitive nature of legal guardian data, leaving some behavioral uncertainty.

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, well-structured sentence with no filler. The main action and scope are front-loaded, and the optional filter is clearly stated at the end.

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 description covers the core invocation facts: list all students, include guardian data, and optionally filter by ID. But it lacks output details, pagination information, and any clarification about how this relates to overlapping sibling tools, so it is only minimally complete.

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 schema already describes pk as an optional student ID with 100% coverage, and the description mostly repeats this by saying 'optionally filtered by student ID.' It adds little semantic value beyond what the schema provides.

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 a specific action and resource: 'List all students including legal guardian data, optionally filtered by student ID.' It is easy to understand the tool's core purpose, but it does not explicitly distinguish itself from similar sibling tools like student_personal_data or direct_attendance_student_overview.

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 no guidance on when to use this tool versus alternatives such as student_personal_data or person_search. It only mentions the optional student ID filter, but does not explain scenarios, exclusions, or conditions that would make this tool the right choice.

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