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 a genuine scope note by saying the response bundles the profile with its "public article cards," hinting at unauthenticated public data, but it says nothing about pagination, result limits, or error behavior.

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 short sentences with the purpose front-loaded and the input instruction second; nothing is padded. Minor redundancy in "Retrieve and return," which say the same thing.

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 description need not explain return values, and it covers purpose and the single input. What is missing for a tool in a dense sibling family is the distinction from jerusalempost_authors and any hint about the accepted URL form.

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% for the single url parameter, so the description must carry the load. "Provide the profile URL to inspect" does correctly identify the parameter as a profile URL (as opposed to an article or section URL), but gives no format or example, leaving the agent to guess the exact URL shape.

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 (Retrieve and return) and resource (one Jerusalem Post author or blogger profile plus its public article cards), so the agent knows exactly what comes back. It does not, however, differentiate itself from the sibling jerusalempost_authors tool, which a reader could easily confuse with this single-profile 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?

"Provide the profile URL to inspect" implicitly signals that this is a lookup-by-known-URL tool rather than a discovery/search tool, which is useful. But it never states when to prefer this over jerusalempost_authors, jerusalempost_article, or jerusalempost_news, so the routing decision is left to inference.

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