get_tour_availability

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

Annotations are absent, so the description must carry the burden of behavioral disclosure. It does not mention read-only nature, permissions, rate limits, or any side effects. It only says 'check', which implies a query but does not explicitly confirm safety or non-mutating 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?

The description is a single, direct sentence with no unnecessary words. It communicates the core purpose efficiently.

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 simple lookup tool, the description plus schema may be sufficient, but it lacks details about how date and month interact, what data is returned, or any assumptions. Without annotations or an output schema, a bit more context would improve completeness.

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?

Input schema coverage is 100%, with each parameter already described in the schema. The description does not add additional meaning to parameters or clarify interactions (e.g., whether date and month are mutually exclusive). Baseline 3 is appropriate since schema handles the heavy lifting.

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?

Description clearly states the operation (check) and resource (available dates and times for a tour experience). It is specific enough to understand the tool's function, though it does not explicitly differentiate from sibling tools like get_weather_insights or ask_travel_expert.

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 guidance is given on when to use this tool versus alternatives, nor any context about prerequisites or typical scenarios. The description is a standalone sentence without situational context.

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