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 that this is a 'public' profile including recent articles, but does not disclose auth requirements, rate limits, or other behavioral traits beyond the annotations.

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?

It is a single front-loaded sentence with no wasted words, efficiently summarizing the profile scope and contents.

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?

With a one-parameter schema, annotations covering read-only/open-world behavior, and an output schema present, the description is nearly complete. It communicates the resource and returned fields well, though it could add minimal guidance on URL usage or alternatives.

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% for the single required url parameter, and the schema already documents it as a canonical cbsnews.com/team/<slug> author URL. The description adds no further parameter meaning, so 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?

The description clearly states the resource: one CBS News author's public team-page profile, and lists the fields returned. It distinguishes the tool from sibling article/news tools by resource type, but it lacks an explicit verb and does not name any sibling for 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?

Usage is implied: use this when you have a CBS News author team-page URL and want that author's profile. There is no explicit when-to-use, when-not-to-use, or alternative tool guidance to help an agent choose between this and cbsnews_article or other author tools.

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