convert_number_base

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

The description discloses the cost ($0.001 USDC via x402), which is a non-obvious behavioral trait not covered by annotations. However, it fails to mention any other behavioral aspects such as input format requirements, potential side effects, or whether it is a read-only operation. The core operation is only implied by the name.

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 short but not effectively concise: the phrase 'Converters tool' is redundant with the tool name and adds no value. While it is front-loaded, the sentence does not earn its place, resulting in under-specification rather than efficient brevity.

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?

With no annotations, no output schema, and a generic params schema, the description needed to compensate by explaining usage and expected inputs. It only provides cost information, leaving the tool completely under-specified for an agent to select and invoke correctly.

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 input schema only exposes a generic 'params' object with the description 'Tool parameters as JSON object', providing no actual parameter details. The description adds nothing about required or optional parameters, so an agent has no information about what inputs are needed to perform the conversion.

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 'convert number base' is nearly identical to the tool name, making it a tautology rather than an explanation. The additional phrase 'Converters tool' is generic and does not distinguish this tool from the many other conversion siblings like binary_convert or convert_units.

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 like binary_convert, hex_to_hsl, or other base-conversion utilities. There are no usage scenarios, exclusions, or alternative tool recommendations.

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