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 some content context by listing the exposed fields (email, X/Twitter handle), but says nothing about resolution behavior, missing-author handling, or how articles are ordered. Adequate but thin against a lower annotation bar.

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 states the resource and its contents with zero wasted words. Appropriately sized for a simple profile lookup.

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 field enumeration is partly redundant and return values need no further explanation. However, the two undocumented identification parameters and the absence of any usage context leave real gaps for a tool with zero required parameters.

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?

Two parameters (url, slug) have 0% schema description coverage and neither is mentioned in the description. The description does not explain whether to supply a URL, a slug, both, or how they relate, leaving the caller with no guidance on the primary identification input.

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 Daily Record author's public profile) and enumerates the returned fields, so an agent can distinguish it from dailyrecord_article/headlines/news/sections. The retrieval verb is only implied, and it never explicitly says it is not the article or section tool.

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 the many sibling *_author, *_article, or *_news tools. Usage must be inferred entirely from the name and the field list.

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