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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds the genuinely useful caveat that returned prices are reference values rather than live inventory, but says nothing about result volume, pagination, or locale/currency behavior.

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 compact sentence with the catalog scope front-loaded and the pricing caveat trailing. Nothing is redundant, though the semicolon construction packs two distinct facts into one clause.

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?

For a zero-required-parameter read-only list tool with no output schema, the description covers what the tool returns conceptually and its pricing caveat. It falls short on the only parameter and on any indication of result set size or absence of filtering besides category.

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 0%, so the description carries more burden than usual, and it never mentions the single 'category' parameter by name. It does implicitly map its three nouns (stays, day-use offers, packages) onto the overnight/day_use/day_combo enum members, which partially compensates, but the 'all' default is undocumented.

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 a specific verb and resource ('List public camping stays, day-use offers and packages') and adds a scoping qualifier ('reference prices, not live booking inventory') that separates it from the pricing and add-on siblings. It does not explicitly name the siblings, so the differentiation is implied rather than stated.

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 phrase 'reference prices, not live booking inventory' implies this is the discovery/catalog tool rather than a booking or exact-quote tool, which is useful context. However, no alternative tool is named and there is no explicit 'use this when...' guidance, so the agent must infer routing.

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