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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds the useful facts that the result set is exactly 30 items and what fields each item carries, but says nothing about pagination, auth requirements, or ordering. With annotations doing the heavy lifting, this is adequate but not rich.

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 sentences, front-loaded with the core purpose and return shape. The trailing enumeration of the eight category values duplicates the schema enum, which is mild redundancy, but overall there is very little waste.

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?

With no output schema, the description compensates by naming the returned fields (id, category, title, what it does, url), which is exactly what an agent needs. A read-only, single-optional-param list tool is nearly fully covered; only pagination/ordering details are absent.

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 100% and the enum is fully defined in the schema, so the baseline is 3. The description merely repeats the same eight enum values verbatim, adding no new meaning such as matching behavior, case sensitivity, or how the filter combines with the fixed 30-item limit.

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?

The description states a specific verb and resource ('List the 30 copy-paste prompts for short-term rental hosts') and even enumerates the returned fields, so an agent immediately knows this is a bulk listing operation distinct from the singular get_prompt sibling. It stops short of explicitly naming get_prompt as the single-item alternative, so differentiation is implied rather than stated.

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?

The text marks category as 'Optional' and lists the valid values, which implies when filtering is useful, but it never states when to use this tool versus get_prompt or what happens when no category is supplied (presumably all 30). Usage is implied rather than spelled out.

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