list_availabilities

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

The description contributes no behavioral information beyond the verb 'List'. Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint, so there is no contradiction, but the description adds no extra context such as pagination behavior, authorization needs, or availability semantics.

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 short phrase with no wasted words and the verb is front-loaded. It is concise, though it is too sparse to add much semantic value.

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?

Structured context is strong due to 100% schema coverage, meaningful annotations, and an output schema. However, the description itself leaves out narrative context about availability semantics, pagination behavior, or when to prefer this tool over get_availability, making it minimally complete but not rich.

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 schema documents all four optional parameters with clear meaning. The description adds no parameter-level detail, so the baseline score of 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?

The description 'List Availabilities' uses a clear verb and resource, so an agent can tell it returns availability records. However, it merely restates the tool name and does not distinguish it from sibling tools like get_availability.

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?

There is no guidance about when to use this tool instead of alternatives such as get_availability or other list_* endpoints. The description implies a generic listing operation but provides no context, exclusions, or routing hints.

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