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

Annotations already declare readOnlyHint and openWorldHint=false, so the safety profile is covered. The description contributes real behavior the annotations do not: the precedence rule that a closed operatingStatus overrides regular hours, the null-when-unknown convention for owner/chain/operator, and the operator/facility relationship. That is substantive semantics beyond structured fields.

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 purpose, then layers field inventory, precedence rules, and null conventions in short declarative sentences with essentially no filler. The final sentence about the operator 'managing the facility' is the least load-bearing but still clarifies the organization-name semantics.

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 shapes need no explanation, and the one required parameter is fully specified in the schema. The description covers the interpretive edge cases an agent would otherwise get wrong (status precedence, null organization fields), leaving only sibling selection as a 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% and the single pagePath parameter is fully documented in the schema, including format constraints and a canonical example. The description only reinforces that the path resolves to 'this GoVisit place' — a marginal addition, 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?

Uses a specific verb-plus-resource ('Read compact page-published visit facts for this GoVisit place') and enumerates the data domains covered: operating status, location, contact details, hours, accessibility, experiences, freshness. It does not explicitly name which sibling to prefer (e.g. get_place_overview or get_place_section), so it is clear on what it does but not fully differentiated from its neighbors.

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 only guidance is internal reading order ('Read operatingStatus before openingHours'), which is a consumption instruction rather than selection criteria. There is no statement of when to choose this over get_place_overview, get_place_section, or the list_* siblings, so the agent must infer the boundary from the phrase 'compact visit facts'.

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