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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds only that results are restricted to a single student and to archived records, and says nothing about ordering, pagination, or result size.

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 sentence-fragment with zero filler and the scoping words ('archived', 'one student') front-loaded. Its brevity is efficient, though the missing verb makes it read like a title restatement rather than a definition.

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-parameter read-only list tool with no output schema, the description is minimally adequate: an agent knows it returns archived assessments for the given student. It is silent on result shape, ordering, and how archived differs from deleted or unlinked assessments, which are the likely points of confusion.

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 studentId parameter is fully documented in the schema, including where to source the value. The phrase 'of one student' is consistent with that but adds no new meaning, so the baseline of 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 description identifies a specific resource (archived assessments) scoped to a single student, but it is a bare noun phrase that largely restates the name/title rather than stating what the tool does. It offers no differentiation from close siblings such as list_assessments, get_latest_assessments, or list_unlinked_assessments.

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 list_assessments or get_latest_assessments, nor any mention of preconditions (e.g., needing a studentId obtained from list_students). The only implicit cue is the word 'archived'.

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