crypto_uuid

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

The description mentions UUID versions v1 and v4 and RFC compliance, but with no annotations, it fails to disclose critical behavior such as parameter effects, error handling, or output format. It does not describe any side effects or constraints.

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 short but includes extraneous 'Menu ID: uuid' and a reference to describe_tool. It could be more concise by focusing on core functionality. The structure is acceptable but not optimally front-loaded.

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 complexity (3 required params, nested object) and absence of output schema, the description is insufficient. It lacks parameter details, usage examples, and return value information, making it incomplete for effective agent invocation.

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 3 required parameters with 0% description coverage. The description provides no additional meaning for 'version', 'quantity', or 'formatting', only hinting at version values (v1/v4). This leaves the agent to guess parameter usage.

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 UUID v1 and v4 identifiers, providing a specific verb ('Generate') and resource ('UUID'). It mentions RFC 4122 compliance, distinguishing it from other crypto tools, though it lacks differentiation from related tools like uuid_validator.

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 on when to use this tool vs alternatives (e.g., other UUID generators or formatting tools). The description defers to 'Use describe_tool for full page guidance', which shifts the burden rather than providing direct context.

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