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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds the underlying endpoint and the returned field set, but discloses nothing about ordering, rate limits, or what an empty result means. Some added value, but not rich behavioral context.

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 compact sentences plus the endpoint path, with the resource and returned fields front-loaded. Every element is relevant, though the trailing GET path is marginal value for an agent.

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 read-only list tool with full schema coverage and safety annotations, the description is largely sufficient, and it usefully enumerates returned fields in the absence of an output schema. Ordering/empty-result semantics are the only notable omissions.

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 restates the three filter dimensions that already exist in the schema (class_id, student_id, entry_date) without adding syntax or behavior detail. Pagination parameters are not mentioned in the description, but the schema covers all five params at 100% coverage, so baseline 3 applies.

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 (List) and resource (class waitlist entries) and enumerates the fields returned (class, student, entry date, position, notes). It is distinguishable from the sibling jackrabbit_create_waitlist_entry by its read-only listing nature, though the write counterpart is never named explicitly.

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?

Filtering options (class, student, or entry date) are stated, which implies usage for narrowing a waitlist, but there is no explicit when-to-use guidance, no mention of when a different listing tool (e.g. get_class_roster or list_classes) is preferable, and no prerequisites.

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