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

No annotations are provided, so the description carries the full behavioral burden. It implies a read operation but says nothing about pagination, whether posts are nested under topics/forums in the response, authentication needs, or how much content is returned.

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?

A single, front-loaded sentence with no filler, and the resource scope is stated immediately. It is efficient, though it stops short of adding any routing or format detail.

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 sensibly communicates the forum/topic/post hierarchy that will be returned, which is useful given there is no output schema. However, with no annotations and an undocumented required parameter, it leaves notable gaps for correct invocation.

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 description coverage is 0% for the single 'course' parameter, and the description only echoes that it operates on 'one course'. It does not clarify whether the value is a course ID, code, or name, leaving the key input ambiguous.

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 names a specific verb ('Return') and resource ('discussion forums/topics/posts') and scopes it to one course, which is clearly distinct from siblings like get_assignments or get_announcements. It does not explicitly name an alternative sibling, so it falls short of a 5.

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?

There is no guidance on when to use this tool versus related read tools such as get_course_content or get_updates, nor any prerequisites or exclusions. Usage must be inferred from the tool name and resource alone.

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