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

Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety profile. The description adds freshness ('Current') and the section-validity constraint, but nothing about pagination, result counts, or ordering. Adequate but not rich given annotations carry the main behavioral load.

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 zero filler; the resource, scope, and prerequisite are all packed in efficiently.

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. For a one-parameter list tool the description covers scope and the input dependency well; the only gap is the exact format of the section value.

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 single 'section' parameter has no enum or description, so the description must compensate. It does so by naming gq_sections as the authoritative source of valid values, though it leaves the exact format (slug vs. display name) unspecified.

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+resource ('Current GQ headlines') with scope ('one public section'), so an agent can distinguish it from gq_sections and gq_article. It stops short of explicitly contrasting with gq_news, but the resource is unambiguous.

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?

Names the prerequisite and the routing source: 'section must come from gq_sections', which tells the agent where to obtain a valid value. No explicit when-not or alternative is given, but the dependency is clearly stated.

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