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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety/scope profile is covered. The description adds only that the page is a 'public team-page profile', which is mild context; it says nothing about pagination of the 'recent articles' list, rate limits, or whether the data is live-scraped. Adequate but thin given annotations do the heavy lifting.

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 leads with the resource and then lists payload contents; there is no filler and every clause carries information.

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 the returned fields need not be re-explained and the description is fine on that front. The gap is on the input side: the one required parameter is undocumented in both schema and description, which is a real omission for a tool an agent must invoke correctly.

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?

The single required parameter 'url' has 0% schema description coverage and the description never clarifies what URL is expected (the author's team page? an arbitrary CBS author URL?). The phrase 'team-page profile' hints at the page type but supplies no format, example, or construction rule, leaving the only required input under-specified.

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?

Names a specific resource (one CBS News author's public team-page profile) and enumerates the payload fields (name, biography, coverage topics, headshot, social links, recent articles), which clearly separates it from cbsnews_article/headlines/news/sections. It stops short of explicitly saying how it differs from sibling tools, but the resource noun plus field list is enough for an agent to place it.

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?

No when-to-use guidance, no alternatives named, and no prerequisites stated. Nothing tells the agent when to reach for an author profile versus pulling an article by the same byline, and the required url argument is never framed as an input to obtain or construct.

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