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

The annotations already indicate this is a non-read-only, non-destructive action. The description adds valuable behavioral context by explicitly stating the quiz is persisted to the student's account and that a connected account is a precondition, which goes beyond the annotation flags.

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 concise sentences with no filler. The core action and persistence side effect are front-loaded, and the account requirement is stated in a single follow-up sentence.

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?

The description, combined with full schema coverage and relevant annotations, gives an agent enough to invoke the tool correctly for a straightforward generation-and-save operation. The main gap is the lack of explicit alternative routing, but this is a minor omission given the simple interface.

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 the input schema already fully documents all parameters. The description mentions the topic but adds no extra semantic detail about difficulty or numQuestions; the baseline of 3 applies because the schema carries the parameter documentation burden.

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 description clearly states a specific verb ('Generate') and resource ('practice quiz on a topic') and adds an important scoping detail: the quiz is saved to the connected student's ScholarNet account. This distinguishes it from sibling tools like generate_flashcards or generate_study_plan.

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?

The description implies the tool is for creating topic-specific practice quizzes and warns that a connected ScholarNet account is required, but it does not explicitly state when to prefer this over sibling tools or when not to use it. The use case is inferable but not directly guided.

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