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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds genuinely useful behavioral constraints beyond that: names must not be translated and prices must not be converted or estimated. It still does not explain ordering, recency window, or pagination, so it stops short of a 5.

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?

Front-loads the core purpose in the first clause, then appends the formatting constraints. No wasted sentences, though the translation/price rules are somewhat tangential to a read tool and could be seen as output-policy boilerplate.

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?

There is no output schema, so the description carries some burden for describing return values; it mentions 'rating and feedback' but not the shape or ordering of results. For a simple two-parameter read tool whose annotations cover the safety profile, this is adequate but not fully complete.

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% – place_id and limit are both documented in the schema, including default and bounds. The description adds no parameter-level meaning beyond what the schema provides, so the 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 and resource ('Get recent guest reviews for a venue') and clarifies the payload ('rating and feedback'). This is clearly distinguishable from siblings like get_experience or get_quote, which return different data entirely, though it does not explicitly name a sibling it should not be confused with.

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 never says when to call this versus alternatives, nor any prerequisite such as needing a valid venue place_id. The formatting instructions about proper nouns and prices are output-handling rules, not usage guidance, so nothing routes the agent to this tool over its siblings.

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