generate_uuid

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the cost ($0.001 USDC via x402), which is a behavioral trait, but does not describe the output format, whether it is deterministic, or any other side effects. This is insufficient for a tool with no annotation support.

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 very short and front-loaded, with no wasted words. The cost information is useful, but the initial 'generate uuid' is redundant with the tool name. Overall, it is concise but could be restructured to add more value in the same space.

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 simplicity of the tool, the description is still incomplete. There is no output schema or annotations, so the description should explain the return format (e.g., UUID v4 string) and any parameter options. The absence of this information makes it hard for an agent to know what to expect or how to configure the call.

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 has a single generic 'params' object with no required fields, and the description provides no additional meaning. Although schema description coverage is technically 100%, the description is just 'Tool parameters as JSON object' and does not clarify what keys are valid or whether any parameters are needed. The tool description does not compensate, leaving parameter semantics largely unspecified.

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 tool generates a UUID, which is a specific verb+resource. However, it essentially restates the tool name without adding distinguishing details from sibling tools like generate_nanoid or generate_ulids. The purpose is clear but lacks explicit differentiation.

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?

There is no guidance on when to use this tool versus alternatives such as generate_nanoid or generate_ulids. The description only mentions the cost, not the contextual use cases or exclusions.

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