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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds that each topic comes 'with its page', which hints at the return shape since no output schema exists, but it says nothing about ordering, completeness, or what happens with an invalid grade.

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?

It is a single short fragment with no wasted words, but it is not front-loaded with a clear verb and reads as an incomplete sentence, which slightly hurts scannability for an agent deciding whether to call it.

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-optional-parameter read-only lookup this is close to sufficient, and the parenthetical examples plus the page mention give a rough sense of the result. Still missing is any statement that this is a reference listing callable before make_worksheet, which an agent would need to place it among its siblings.

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 single optional grade parameter is fully documented in the schema with range and default behavior. The description adds no meaning beyond that, so the 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?

The phrase 'The worksheet topics for each grade' identifies the resource and gives illustrative examples (fractions, measurement, two-step problems), but it is a noun fragment rather than a verb+resource statement, so the agent must infer that this lists topics rather than describing them or fetching a single topic. Nothing distinguishes it from siblings like list_skills.

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 when-to-use guidance, no mention of when to prefer make_worksheet or list_skills, and no stated conditions or exclusions. The only scoping hint ('Leave out for all six') lives in the schema, not the description.

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