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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds only the loose scoping notion of "this account's past attempts" — it says nothing about result volume, pagination, whether in-progress attempts are included, or ordering, which are the details that matter for a read list call.

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?

A single front-loaded sentence with no filler, so nothing is wasted. However, its brevity comes from omission rather than economy — the same one line could have carried disambiguation without bloat.

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 output schema exists, so return shape needn't be explained, and there is only one well-documented parameter. What is still missing for a tool in this crowded quiz-attempt family is a statement of what makes this list result different from the per-attempt detail 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?

Only one parameter and the schema documents it at 100% coverage, including the hint to obtain it from list_quizzes. The description's "one quiz" corroborates that, but adds no format or edge-case detail beyond the schema, 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?

States a concrete verb and resource: retrieving the account's past attempts for one quiz. The purpose is immediately understandable, but the sibling set contains get_quiz_attempt_data, get_quiz_attempt_summary, get_quiz_attempt_review, and get_quiz_best_grade, and the description does nothing to distinguish this list-level call from those.

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 guidance on when to choose this over the several related quiz-attempt siblings, and no stated preconditions (e.g. whether the quiz must have attempts, whether it covers all users or just the caller). The agent must infer routing entirely from the name.

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