Get calendar events

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

With no annotations, the description itself must signal behavior; 'Get' clearly implies a read-only retrieval within the course scope. However, it does not disclose what the returned events look like, whether date-range filtering is available, pagination, or authentication expectations, so transparency is partial.

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 front-loaded sentence with no filler words. Every word carries meaning, and it is easy to scan quickly.

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 one-parameter read-only tool with no output schema, the description provides the essential what and scope, and the schema covers the parameter. It is less complete than ideal because it offers no usage guidance or return-value context and has no annotations to fall back on.

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?

Schema coverage is 100% and the courseId property already explains that it is the course's orgUnitId from list_courses. The description's 'for a course' reinforces that single parameter but adds no new semantic information beyond the schema.

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 uses a specific verb ('Get'), a specific resource ('calendar events'), and a scope ('for a course'), so an agent can tell it retrieves course-calendar data rather than content, grades, or announcements. It doesn't explicitly contrast it with sibling tools, so it misses the top score.

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 given about when to call this tool instead of a sibling such as get_course_content or get_assignments. The phrase 'for a course' indicates a required parameter but provides no selection heuristics or exclusions.

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