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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false and destructiveHint=false, so the safety profile is covered. The description usefully adds that results are editorial metadata rather than supplier inventory, but says nothing about pagination behavior (limit/offset) or result shape, which would be the added value given the annotations.

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 tight sentences with the core action front-loaded and the disambiguating scope constraint immediately following. No filler, nothing redundant.

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?

For a simple, zero-required-param read search tool the definition is mostly adequate, and there is no output schema so return values need not be explained. Still, it omits pagination semantics and any routing guidance against read_guide/create_search_link, leaving gaps for a tool that shares a namespace with two siblings.

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 0% across four parameters (limit, query, locale, offset), and the description supplies no parameter meaning at all — no hint that query matches editorial metadata, that locale constrains language, or how limit/offset paginate. With a zero-coverage schema the description was expected to compensate and does not.

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 (Find) and resource (published city/attraction/day-trip guides) with clear scope, and the 'editorial metadata, not supplier inventory' clause separates it from inventory-style searches. However, it never names or differentiates from its actual siblings read_guide and create_search_link, so an agent still has to infer the boundary.

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 scope line ('searches editorial metadata, not supplier inventory') implies when this tool is appropriate versus inventory lookups, but there is no explicit when-to-use guidance and no mention of the alternatives read_guide (fetch one guide) or create_search_link. Usage is only implied.

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