A4/5.0

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint=false, so the safety profile is covered. The description adds only that results come from 'published FAQs'; it says nothing about pagination behavior, result limits, or what happens when a destination has no FAQ entry, which would be genuinely useful context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single tight sentence with the primary behavior first and the null-query special case second; no filler and nothing redundant.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

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 required destination parameter is described in-schema with a pointer to list_cities. The definition is nearly complete, missing only minor operational detail such as whether a query with no match returns an empty list.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so limit/cursor/query/destination are all documented, and the schema already shows query defaults to null. The description's 'omit query' note restates the schema default rather than adding format or matching semantics, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Answer a question about a named destination from its published FAQs') and explicitly covers the no-query case, which cleanly separates it from the sibling venue_faq and from destination_guide/overview.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The 'omit query to read them all' clause gives clear conditional usage for the query parameter. It stops short of naming the alternative sibling (venue_faq) or stating when a destination FAQ is preferable to destination_guide, so routing between siblings is left partly to inference.

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