create_company

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

No annotations are provided, and the description does not disclose any behavioral traits such as required permissions, idempotency, side effects (e.g., does it create related records?), or error handling (e.g., what happens if a company with the same name exists?). The agent has no insight beyond the fact that it creates.

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 extremely concise at one sentence, but this brevity comes at the cost of missing essential behavioral and parameter details. Front-loading is minimal but acceptable for a simple create tool.

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?

Given the tool has 4 parameters (1 required) and an output schema, the description is incomplete. While the output schema exists, the description fails to explain creation behavior, such as whether the name must be unique or if optional fields can be updated later. The agent lacks sufficient context to use the tool confidently.

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 must compensate. However, it provides no information about the parameters beyond their names. For instance, it does not explain that 'email' could be a primary contact email or that 'main_phone_number' format expectations. The defaults are present in the schema but not explained.

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 'Create a new company.' clearly states the action and resource, distinguishing it from other create tools like create_client or create_case. However, it lacks additional context about what a 'company' entity represents within the system.

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 provided on when to use this tool versus alternatives such as update_company or add_client_to_company. There is no mention of prerequisites, use cases, or scenarios where this tool should be avoided.

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