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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds real value beyond that by enumerating the payload (ratings gap, Asian reviewer share, dish mentions, quotes, cross-platform ratings, links), which tells the agent what it gets back. It does not say what happens when a name is ambiguous or matches nothing.

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?

One front-loaded sentence that names the resource first and then lists the contents. The enumeration is long but each item is a distinct piece of returned data, so it earns its length rather than padding.

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 must convey returns, and it does so thoroughly. For a 3-parameter, read-only lookup tool the only real omission is behavior on ambiguous or missing names, which the schema hints at but the description never addresses.

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% with per-parameter descriptions and enums for city and type, so the schema already carries the parameter meaning. The description adds no syntax, format, or disambiguation guidance beyond it; baseline 3 applies.

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 ('Full Asian Recs page for one place') and enumerates exactly what the page contains, so the agent knows this is a detail fetch rather than a list. The sibling search_places is not named, but the singular 'one place' framing implicitly separates it from a search/list tool.

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 explicit when-to-use sentence, no prerequisites, and no mention of the sibling tools (search_places, list_filters). The usage is only implied: fetch this after a search has surfaced a specific place. That is adequate but leaves routing to inference.

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