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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds a useful behavioral detail beyond the annotations: it returns only 'one page of their recent articles', signaling pagination and partial results. No auth or rate-limit context is given.

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 that identifies the resource first and the payload second, with no filler. Appropriately sized, though it stops short of adding the routing guidance it could hold.

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?

An output schema exists, so return values need not be explained. However, with three fully undocumented parameters and no guidance on url-vs-slug selection or required input, the definition leaves an agent unable to confidently construct a call.

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% across three params (url, page, slug), so the description must carry the burden. It hints that 'page' controls pagination of recent articles, but never explains the distinction between url and slug or which to supply (none are required).

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+resource ('One GQ contributor's public profile') and enumerates the returned fields (name, biography, headshot, social links, recent articles). It is clearly distinguishable from gq_article/gq_news in practice, though it never explicitly names those siblings to differentiate.

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 when-to-use guidance, no prerequisites, and no alternatives named. Usage is only weakly implied by the field list. An agent is not told how to choose this over gq_article or how to obtain the identifying slug/url.

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