divide

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

No annotations are provided, so the description carries the full behavioral burden. It discloses the ZeroDivisionError condition, logging behavior, and that responses are either success or error dictionaries. This gives the agent a complete picture of runtime 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 well-structured with Args, Returns, Raises, and Notes sections, and the core action is front-loaded. It contains slight redundancy between the Returns line and the Notes about success/error responses, but overall every section earns its place.

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 one-parameter arithmetic tool, the description is complete: it defines the input object, explains the roles of both fields, specifies the error condition, and describes the return behavior. An output schema exists, so the missing formal return schema is not a gap.

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 coverage is 0%, and the description fully compensates by explaining that `a` is the numerator, `b` is the denominator, and that a zero `b` causes an error. It provides meaningful semantic meaning beyond the raw schema property names.

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 operation: 'Perform division of two numbers provided in the TwoNumberOperation object.' The verb 'divide' plus explicit numerator/denominator roles distinguishes it from all sibling math tools.

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?

The description implies the tool should be used whenever division is required, but it does not explicitly discuss when to choose this tool over alternatives like modulus or power. Usage context is clear from the operation name and description, but no exclusion or alternative guidance is given.

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