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

Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety profile. The description adds useful context about what the page contains, but says nothing about the URL form or what the fetch returns beyond the annotation-covered basics.

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 with no filler, leading with the resource and then listing contents. Efficient, though the trailing content enumeration leans on what the output schema presumably covers.

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?

Output schema presence means return values needn't be spelled out, and annotations cover safety. The remaining gap is the url parameter's expected form, which is undocumented in both schema and description, and the lack of any usage routing within the nyt_* family.

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% for the single url parameter, and the description never mentions it or clarifies whether it expects a byline-page URL versus an article URL. It adds page-content context but no parameter-level meaning, so the schema carries the load alone.

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 resource — one NYT contributor's public byline page — and enumerates its contents (name, tagline, About/Contact, recent articles). This clearly separates it from nyt_article/nyt_headlines, though it never names a sibling to sharpen the contrast.

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 or when-not-to-use guidance. The description implies it fetches an author profile, but offers no routing versus nyt_article, nyt_headlines, or nyt_sections, leaving the agent to infer selection.

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