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

No annotations are supplied, so the description carries the full burden; 'list' implies a read-only operation, which is the main behavioral signal available. It says nothing about result volume, ordering, pagination, or whether the list is exhaustive per grade band.

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 the resource and scope stated immediately and no filler. Every element earns its place.

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?

Simple one-parameter list tool with an output schema, so return-value explanation is unnecessary and the key gap — valid grade-band values — is covered. Ordering and pagination expectations are the only notable omissions.

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 0% and the schema declares grade_band as a bare string with no enum, so the description's enumeration of K-2, 3-5, 6-8, and 9-12 supplies the only constraint on valid values. That is meaningful added value over the schema, though it does not state case sensitivity or invalid-value behavior.

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 (list) and resource (skills in MALN's skill graph) with scope (grade band). The singular counterpart get_skill and the consumer draft_practice_set are implicitly distinguishable, though no sibling is named explicitly.

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 or when-not-to-use guidance and no mention of alternatives such as get_skill for detail or draft_practice_set for follow-on use. The browsing-before-fetching intent must be inferred from the verb 'list' alone.

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