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

The annotations already declare this a safe, read-only, idempotent, closed-world operation. The description adds that only public authors are returned and mentions URLs and page metadata, but it does not cover pagination behavior or result ordering beyond what the schema already states.

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?

Two short sentences with the core action and return shape front-loaded. Nothing is redundant or padded.

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 filtered-list tool with no output schema, the description supplies the essential return shape (URLs and page metadata) and the filtering behavior. Pagination limits and ordering are left to the schema, which is acceptable but keeps it just short of fully 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 100%, and the schema already documents page bounds and that category is a dynasty name from list_dynasties, not a group name. The description adds only that the dynasty filter is optional, which is already implied by the absence of required parameters, so a baseline 3 is appropriate.

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 and resource: browse public authors, with an optional dynasty filter, and notes that it returns URLs and page metadata. It is clearly distinct from get_author, though the description does not explicitly name that sibling as the single-author alternative.

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?

Conveys that the dynasty filter is optional and that results are public authors, implying usage for browsing rather than fetching a specific author. It offers no explicit when-to-use or when-not guidance and does not name get_author or search_poetry as alternatives.

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