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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and external-data reach are covered. The description adds only the word 'dataset', which weakly hints the data comes from a bulk-collected source rather than live Google Maps, but says nothing about freshness, coverage, or behavior when the id is unknown.

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 sentence with the lookup key front-loaded and no filler. It is on the verge of being under-specified rather than merely concise, but nothing in it is wasted.

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 described, and annotations cover the safety profile. Still, for a lookup-by-id tool the description omits the practical prerequisite (where the place id comes from) and any note on missing-record behavior, leaving a small but real gap.

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 coverage is 100% for the single required parameter, and the schema already states 'Google Maps place id of the business.' The description restates 'by place id' without adding format, provenance, or where to obtain the id, so the baseline of 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?

The description names the specific resource (a Google Maps business dataset record) and its lookup key (place id), which is enough to separate it from the sibling search/nearby/facets tools. It is a noun phrase with no explicit verb, but the retrieval intent is unambiguous.

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 and no reference to the alternatives. An agent is not told that datasets_google_map_search must be called first to obtain a place id, nor how this differs from google_map_place, which is the most obvious near-duplicate sibling.

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