degreesToRadians

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

No annotations are provided, so the description carries the burden. It implies a stateless pure computation with no side effects, but does not state the return form (radians) or how invalid input is handled. For a trivial single-value conversion the gap is minor, but it is unstated.

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?

Two short sentences with zero waste; the core operation is front-loaded and the routing hint follows. Nothing needs trimming.

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 one-parameter pure math tool with a fully documented schema and no output schema, the description is essentially sufficient—purpose plus sibling routing is all that is required. Only a note on the returned unit/precision would make it airtight.

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% ('The number in degrees to convert to radians'), so the single parameter is fully documented in structured data. The description adds no format, range, or type detail beyond that, so baseline 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?

States a specific verb and resource ('Converts degrees to radians'), which cleanly distinguishes it from its sibling radiansToDegrees and the other arithmetic tools. An agent can identify the operation without opening the schema.

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?

Explicitly routes multi-step or chained work to batch_calc, naming both the alternative and the condition that selects it. That is exactly the routing guidance an agent needs in a large math-tool family.

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