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 recent stories are bundled with the profile, which is useful context, but says nothing about pagination of those stories, rate limits, or required auth.

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; the resource and its returned fields come first, and every clause earns its place.

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 it correctly summarizes the payload. However, the undocumented url parameter leaves the agent without enough to construct a correct call.

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 'url' parameter has 0% schema description coverage, and the description does not clarify what URL is expected (an author page URL vs. a profile path) or its format. With low coverage the description should compensate but does not.

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 (one India Today author's public profile) and enumerates the payload (name, job title, headshot, biography, recent stories), so the agent knows exactly what it fetches. It does not explicitly distinguish itself from siblings like indiatoday_article or indiatoday_headlines, though the 'author' naming makes the scope reasonably inferable.

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 statement of when to use this tool versus indiatoday_article or indiatoday_headlines, and no prerequisite or input guidance. Usage is only implied by the phrase 'author's public profile'.

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