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

Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety and external-fetch profile. The description adds only 'fresh' and 'public feed', which gestures at recency and an unauthenticated source but says nothing about ordering, pagination, or result count.

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 short, front-loaded sentence with no filler. It is efficient, though the brevity comes at the cost of the missing differentiation noted elsewhere.

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. But for a zero-param feed tool sitting among four ambiguous GQ siblings, the description does not supply enough to route the agent confidently — the main missing piece is sibling differentiation, not parameter or return detail.

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?

The tool takes zero parameters, so the schema carries no semantics to compensate for. Baseline 4 applies; nothing in the description is required or missing on this dimension.

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?

It states a resource ('GQ top stories') and a source ('the public feed'), which gives a rough sense of the operation. However, it never says what is returned (a list of articles? links?) and does not distinguish itself from the four sibling GQ tools, especially gq_headlines, whose purpose sounds nearly identical.

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 when-to-use guidance at all — no mention of when to prefer this over gq_headlines, gq_article, or gq_sections, and no preconditions or exclusions. The agent must guess from the name alone.

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