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

No annotations are supplied, so the description carries the full burden; it does well by disclosing ordering, the returned fields including anonymization ('reviewer first-name-only'), and the no-auth requirement. It omits edge behavior such as what happens when neither classId nor classSlug is supplied, or whether the result is capped/paginated beyond the limit.

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?

Two short sentences, front-loaded with purpose and ordering, then return contents and the auth note. Every clause carries information; nothing is redundant.

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 small three-parameter read tool with no output schema, the description covers purpose, ordering, and return shape including privacy handling. The remaining gap is the unresolved semantics of the two optional identifier parameters, which is the main thing an agent could get wrong.

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%, so the description has to compensate and only partly does: it explains that classId and classSlug are alternative identifiers, but not their precedence or mutual exclusivity, and says nothing about 'limit' beyond what the schema constraints already encode (default 10, max 50).

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?

States a specific verb and resource ('List reviews for a specific class'), names the two lookup keys (id or slug), and adds the ordering ('latest first'). No sibling tool covers reviews, so there is no ambiguity to resolve against the likes of search_classes or get_mentor.

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?

Gives clear context for use (fetching the review set for one class, identified by id or slug) and a useful operational note ('No auth required'), but never states exclusions or what to do when the class identifier is unknown — e.g., whether to fall back to search_classes first.

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