create_association_unit

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

The description only says a new association unit is created; it does not disclose input requirements, return behavior, authorization needs, side effects, or error conditions. With no annotations available, this leaves the tool's behavioral profile largely undisclosed.

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, focused sentence with no filler or repetition. It is easy to parse, though it is so brief that it borders on under-specification rather than intentional conciseness.

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?

Despite the presence of an output schema, the description lacks essential context such as required fields within unit_data, prerequisites, or how association units relate to other entities. The tool's usefulness depends on details that are absent from both the description and the parameter schema.

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?

The single parameter unit_data has a schema with additionalProperties:true and zero description coverage. The tool description does not explain what unit_data should contain, so the agent must guess the structure of this nested object.

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 is a specific verb+resource statement: 'Create a new association unit.' It clearly distinguishes the tool from siblings like create_association, create_rental_unit, and update_association_unit by naming the exact entity type.

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. The description only states the action and resource, leaving the agent to infer the appropriate context from the tool name and sibling list.

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