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

With no annotations, the description carries full burden. It implies read-only operation by saying 'fetches' but does not explicitly state safety, side effects, or restrictions. The list of return fields provides some transparency, but behavioral traits beyond that are absent.

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?

The description is concise with two short paragraphs. The first sentence acts as a header, and the main content efficiently describes the return fields and use cases. Could be slightly trimmed in the use cases list, but overall well-structured.

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?

Given no output schema, the description compensates by listing key return fields. It covers input (placeId, domain, hl) and output comprehensively for a simple data fetch tool. Minor missing elements like error handling or response format do not significantly detract.

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%, so baseline is 3. The description mentions domain/language localization, which adds context to the parameters but does not provide deeper semantics beyond the schema descriptions.

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 clearly states the tool fetches full Google Maps place data by placeId, listing many specific return fields. It distinguishes from sibling tools (e.g., search, reviews, photos) by focusing on place details.

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 description lists use cases (local SEO audits, POI enrichment, lead generation, competitor mapping) but does not explicitly compare to sibling tools or state when not to use it. Usage is implied rather than explicitly guided.

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