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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds genuinely new behavioral facts beyond that: the experiences section returns ALL published experience cards in the page language across all audiences, while other lists cap at 20 items — a meaningful disclosure of result-set truncation and language/audience scoping.

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?

Three short sentences, front-loaded with the core action, then the section-specific exception, then the general limit. The only minor waste is the "such as its overview, highlights, or updates" example list, which partially restates enum values already in the schema.

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 needn't be described, and the two required parameters are fully specified in the schema. The description fills the remaining gap that matters for a reader tool — that results can be truncated or audience-wide — leaving little an agent needs that is missing.

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% and the enum of eight sections is fully documented in the schema, so the baseline is 3. The description's added value is marginal: it clarifies that content is "published" and that the experiences section is scoped to the page language for all audiences, but it does not explain pagePath semantics or section-specific behavior for the other enum values beyond the 20-item cap.

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 pair ("Read one part of a destination page") and enumerates concrete example sections (overview, highlights, updates). It is clear that this is a destination-scoped reader, though it never explicitly separates itself from get_destination_overview or the list_destination_* siblings whose names overlap with its enum values.

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?

No when-to-use or when-not-to-use guidance is given, and no alternative is named. The description implies you call it to fetch one named section of a destination page, but an agent must infer on its own whether to use section="highlights" here versus calling list_destination_highlights, or whether section="overview" duplicates get_destination_overview.

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