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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds genuinely useful behavior beyond that: each call produces a fresh version of the problems (i.e., non-deterministic generation), and the output is a PDF plus a separate answer-key copy.

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 sentences, front-loaded with the core purpose, followed by the fresh-version behavior and the topic-id sourcing. Efficient with no filler, though the last sentence could be folded in more tightly.

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?

With no output schema, the description does the work of explaining what comes back (PDF worksheet plus separate answer key). Combined with full schema parameter coverage and annotations covering safety, it is nearly complete; it omits delivery/location details of the generated file.

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 100%, so every parameter (count, topic, levels, version, questionTypes) is already documented in the schema. The description reinforces that topics come from topic search and hints at the version parameter, but adds little beyond the structured fields, 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 (makes/creates), resource (printable math worksheet for one topic), and output format (PDF with a separate answer-key copy). This clearly distinguishes it from the sibling search_worksheets, which only finds existing sheets.

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?

Implies the usage path by directing the agent to obtain topic ids from 'the topic search,' but gives no explicit when-to-use/when-not statement or contrast with search_worksheets. Usage is inferred rather than stated.

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