get_first_available_appointment

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

With no annotations, the description carries full burden. It discloses that results start from current time onward, but omits ordering (e.g., earliest first), whether it returns a list or single value, and if all docks/load types are included. Moderate transparency.

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?

Single sentence, no wasted words, front-loaded with purpose. Concise and well-structured.

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?

Without output schema, the description should clarify return structure. It says 'for each dock and loadtype' implying multiple results, but does not specify format (e.g., list of objects) or if there are any constraints. Somewhat incomplete for an agent to fully understand output.

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?

No parameters in schema (100% coverage by default), so description does not need to add parameter details. As the sole source of meaning for the void input, it adequately implies the tool takes no arguments.

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 clearly states the tool finds the next available appointment time for each dock and loadtype, starting from current time. It uses a specific verb 'finds' and resource 'appointment time', and distinguishes from siblings like 'find_and_book_appointment' or 'get_dock_availability' by implying a read-only, future-oriented search.

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 explicit guidance on when to use this tool versus alternatives. While the purpose is clear, the description does not mention when not to use it (e.g., if booking is needed) or compare with sibling tools like 'find_and_book_appointment' or 'get_dock_availability'.

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