get_course_details

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

Annotations are absent, so the description carries the full burden of behavioral disclosure. It does mention the output fields, which gives some indication of what to expect, and the verb 'Get' implies a read operation. However, it does not explicitly state that the operation has no side effects, whether any permissions are required, or how errors or missing data are handled. For a simple read tool, this is acceptable but not thorough.

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 that leads with the action and subject. There is no extraneous wording, making it easy to parse quickly. It could be slightly more informative without losing conciseness, but as is, it is well-structured.

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 simple get-one tool with one parameter, the description covers the core purpose and output fields. However, it omits usage guidance, and the output schema (though present) is not captured in the description. Given the many similar 'get' siblings, more context (e.g., what distinguishes this from get_syllabus) would make it 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 provides no description for course_identifier, and the description does not clarify what an identifier looks like (e.g., a numeric ID or a string code). With 0% schema coverage, the description should compensate, but it offers zero additional meaning about the parameter.

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?

Description clearly states the verb 'Get', the resource 'details for one course', and enumerates specific fields (code, name, dates, time zone, role). This makes the purpose unambiguous and distinct from siblings like list_courses or get_syllabus.

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 guidance is provided about when to use this tool versus alternatives. With many sibling tools (e.g., list_courses, get_course_structure, get_syllabus), an agent is left to infer selection criteria purely from the name and purpose. There is no mention of exclusions or preferred scenarios.

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