Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety and open-web profile is covered. The description adds that only 'public' articles are returned and that the payload contains metadata plus body paragraphs, but it omits any access, rate-limit, or error behavior context.

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. It is appropriately sized for a simple one-parameter fetch tool, though the brevity is part of why detail is missing.

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 no explanation, and annotations cover the safety profile. For a one-param fetch tool the description is adequate but leaves the URL format and any usage context unstated.

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 single required 'url' parameter is undocumented in the schema, and the description only implies it identifies 'one' article without giving format (full URL vs slug, canonical vs canonicalized). With low coverage the description should compensate and largely 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?

States a specific resource ('Salon article') and what it returns ('metadata and body paragraphs'), which lets an agent distinguish it from the sibling salon_headlines, salon_news, and salon_sections tools. It is a noun phrase rather than a verb+resource, but the scope ('one public article') is precise.

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 explicit when-to-use guidance, no mention of the alternatives (salon_headlines for lists, salon_news for feeds), and no prerequisites stated. The agent must infer that this is the detail tool from the name and the word 'One'.

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