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 the page includes the author's 'most recent bylined articles,' implying a recency-limited listing, but says nothing about pagination, request limits, or whether an author without a byline page errors.

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 tight sentence that front-loads the resource and lists the payload fields with no filler. It is slightly under-specified rather than padded, which is a mild structural weakness for a tool with two undocumented parameters.

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?

Because an output schema exists, the description need not explain return values, and annotations cover the safety profile. The remaining gap is the url/slug ambiguity, which the description never resolves despite 0% schema coverage, leaving the agent unsure how to actually invoke the tool.

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%, so the description carries the full burden for the two parameters (url and slug) and provides nothing beyond what the schema provides. The agent gets no guidance on which identifier to supply, whether one is preferred, or what format each expects.

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 (a Forbes contributor/staff author byline page) and enumerates the returned content (name, display type, bio, headshot, recent bylined articles), so the agent knows exactly what it fetches. It does not, however, differentiate itself from the adjacent sibling forbes_person, which an agent could easily confuse with an author lookup.

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 when-to-use guidance, no exclusions, and no mention of alternatives such as forbes_person or forbes_article. The agent must infer that this is the right tool for author profiles purely from the name.

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