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 scoping context ('Current', 'one public section' at a time), but says nothing about volume, ordering, or freshness beyond the word 'Current'.

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 compact sentence, front-loaded with the resource and immediately followed by the input constraint. Nothing is wasted and there is no filler.

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 explained, and the annotations carry the safety profile. The description covers purpose and the key input constraint; only minor gaps remain around result ordering/freshness.

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% and the schema gives only a bare string type, so the description carries the burden. It meaningfully constrains the parameter by stating the section must be sourced from salon_sections, telling the agent where valid values come from even though it does not enumerate them.

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 and resource ('Current Salon headlines') and scopes it to 'one public section', which distinguishes it from the broader salon_news sibling. It does not explicitly name the alternative tools (salon_news, salon_article), so it stops short of the full sibling differentiation a 5 requires.

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?

Gives a clear prerequisite: 'section must come from salon_sections', which routes the agent to the correct tool for discovering valid inputs. It lacks an explicit when-not or a direct contrast with salon_news, so it is clear context without full routing guidance.

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