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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint false, and openWorldHint false. The description adds useful scope by stating only published records are returned and that results include names and page URLs, but it omits pagination, ordering, and any rate-limit behavior.

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?

The description is appropriately short at two sentences, but the first sentence is a fragment without a clear action verb and does not front-load the tool's purpose. The second sentence usefully explains the slug format.

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 simple two-parameter read tool with no output schema, the description gives a reasonable indication of return contents. However, it leaves the type parameter undefined and does not address result ordering or pagination, leaving the definition partially complete.

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%, so the description must carry parameter meaning. It thoroughly explains the slug format and gives an example, but the type parameter is only indirectly hinted at through 'coin collection' and is not defined or mapped to its enum values.

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 that the tool returns every published record in a set, collection, or range, along with each record's name and page URL. This distinguishes it from an item-level tool like get_item, though it does not explicitly name or contrast with sibling tools.

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 explicit guidance on when to use this tool versus alternatives such as get_item or search_catalogue. The slug example helps with invocation but does not address tool selection or usage context.

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