academy_premium_catalog

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so safety is covered structurally, but the description contributes nothing further. It does not explain pagination behavior, locale effects, or how idempotencyKey is used on a read operation.

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 short, but shortness here reflects under-specification rather than conciseness. A single redundant fragment front-loads a restated name instead of the operation's purpose.

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 four parameters, a paginated read shape, and an output schema, the definition should at minimum state that this returns a paginated premium catalog. Instead it offers a four-word label, leaving the agent unable to predict results or pagination.

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 only 50%: limit and cursor are undocumented, while locale and idempotencyKey have schema descriptions. The description compensates for none of this gap, saying nothing about page size, cursor semantics, or locale selection.

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?

"premiumCatalog: Academy commerce operation" restates the tool name and adds only the vague label "commerce operation." It never says whether this lists premium products, retrieves pricing, or performs a purchase, and it does not distinguish it from siblings like academy_premium_preview or academy_library.

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 guidance, no exclusion of alternatives, and no mention of the obvious sibling academy_premium_preview. The agent is left to guess the relationship between the catalog and preview tools entirely.

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