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 useful content context by listing the fields and noting that recent articles are included, but it omits anything about the required identifying input or pagination/limits on those recent articles.

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?

One compact sentence that front-loads the resource and then lists the returned fields; no filler. Slightly awkward phrasing ('One The New Yorker contributor's'), but structurally efficient.

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 enumerating return fields is optional rather than essential, and the annotations carry the safety profile. The real gap is input semantics — how the agent is supposed to supply the author's URL — which leaves the definition only minimally sufficient.

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?

There is exactly one required parameter ('url') with 0% schema description coverage, and the description never mentions it, its format, or whether it must be a New Yorker author-profile URL versus a bare author name. With a single undocumented required param, the description should have compensated and does not.

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 names a specific resource ('One The New Yorker contributor's public profile') and enumerates what the profile contains (name, photo, biography, links, recent articles), so an agent can tell this apart from newyorker_article or newyorker_headlines. However, it never explicitly names those siblings or states the differentiating condition, so it falls short of a 5.

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?

The description gives no when-to-use guidance, no prerequisites, and no indication of which sibling to pick instead (e.g. newyorker_article for a single piece, newyorker_headlines for a feed). Usage is only weakly implied by the word 'profile'.

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