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 substance by stating the return payload is a public profile plus recent story links, but does not disclose pagination, count limits, or what happens with an unrecognized slug.

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?

Two sentences, zero filler: the first delivers purpose and output, the second delivers the input contract. Ideally front-loaded and appropriately sized.

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 return values need not be enumerated, and the read-only annotations remove mutation risk. What remains thin is parameter requirements (0 required but this is unstated) and the absence of any usage routing, though for a simple two-param lookup the description is largely 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?

Schema coverage is 0%, so the description must carry the burden, and it does explain that either a canonical slug or an /author/<slug> URL is acceptable for the two parameters. It does not clarify which of url/slug is preferred or that neither is required, leaving some ambiguity given both are optional.

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 verb (look up) and resource (Sportskeeda author) and names the returned content: public profile plus recent story links. It does not distinguish itself from the many other *_author siblings, but the resource owner (Sportskeeda) makes identity unambiguous among them.

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 only instructs how to supply the identifier, not when to select this tool over alternatives. There is no when-to-use, no exclusion, and no routing to a sibling such as sportskeeda_article or sportskeeda_profile.

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