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

With readOnlyHint already declaring the safety profile, the description still adds real behavioral context: the 200-items-per-page pagination model, the continue-if-full rule, and a concrete quota cost (one of 30 requests per hour per API key). It also compensates for the missing output schema by listing returned fields. Only the raw endpoint line is redundant.

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?

Three compact sentences, front-loaded with purpose, then pagination, then quota and endpoint. Every clause carries operational value for the caller; nothing is padding.

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 single-optional-parameter, read-only listing tool with no output schema, the description covers purpose, return fields, pagination semantics, and rate-limit cost. An agent has everything needed to call it and to loop correctly.

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%, so the baseline is 3, but the description adds meaning the schema lacks: the page size of 200 and the fact that pages are 1-based and sequential, which is what an agent needs to decide how many page calls to make.

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 the questions of the question bank') and even enumerates the returned fields, so the operation is unambiguous. It does not explicitly contrast itself with the singular classmarker_get_question sibling, so it falls short of full sibling differentiation.

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?

Usage is implied by the resource name, and the description gives pagination guidance ('a full page means more may follow, so ask for the next page'). However, it never states when to prefer this over get_question or other listing siblings, nor does it name any exclusions.

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