get_student

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

No annotations are provided, so the description carries the full burden. It discloses that this is a read operation ('Retrieve') and states that it returns a profile with name, email, and roll number. However, it does not mention error handling, permissions, rate limits, or any side effects. For a simple get-by-ID operation, this is minimally adequate.

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, using a clean docstring format with Args and Returns. It contains no fluff, and each sentence adds value.

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 tool is simple (one parameter) and has an output schema that presumably details the return value. The description adds the returned fields (name, email, roll number), which is helpful. It is largely complete for a single-profile retrieval tool, though it could mention behavior if the student does not exist.

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 only defines student_id as a string. The description adds that it is a UUID, which is meaningful and helps the agent provide the correct value. With 0% schema description coverage, the description compensates well.

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 the tool's purpose: 'Retrieve a student's profile by their UUID.' It uses a specific verb (retrieve), specifies the resource (student's profile), and indicates the key parameter (UUID). This distinguishes it from sibling tools like list_students (bulk retrieval) and search_students (filtered search).

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 implies usage when a student UUID is available, but it does not explicitly mention when to use this tool versus alternatives such as list_students or search_students. No when-not-to-use guidance is provided.

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