OBS Course Grades

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

With no annotations, the description carries full burden. It declares a read operation, which is consistent with the tool name. However, it does not disclose additional behavioral traits like response format, pagination, or potential limitations, leaving some 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, efficient sentence with no unnecessary words, front-loading the action and parameters. It is well-structured for quick comprehension, though it could be slightly more informative without losing conciseness.

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 tool has five optional parameters and an output schema, the description provides a high-level summary but omits details on the return value and semantics of unmentioned parameters. It is sufficient for a simple read tool but has notable gaps.

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 description adds meaning for two of five parameters by mentioning identification by sinifId (class_id) or course code (course). The other parameters (semester, include_letter, include_midterms) are not explained. With 0% schema coverage, this partial elucidation is helpful but incomplete.

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 reads midterm and/or letter grades for an OBS class, specifying the identification methods (by sinifId or course code). It distinguishes from sibling tools like 'get_course_grades' by the OBS prefix and the explicit mention of grade types.

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 provides no guidance on when to use this tool versus alternatives, such as the similar 'get_course_grades'. No context about prerequisites, exclusions, or preferred use cases is given.

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