generate_uuid

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

No annotations are present, so the description carries the burden of behavioral disclosure. It states that the tool generates random v4 UUIDs, which is a clear behavioral fact. However, it omits additional context such as whether the randomness is cryptographically secure or whether the result is a string, though these are somewhat implied by the tool's purpose.

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 a single sentence, 'Generate random v4 UUIDs.', which is perfectly front-loaded and free of any redundant wording. Every word contributes to the core purpose.

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 tool's simplicity (one optional parameter, no output schema), the description and schema together adequately cover usage. The only minor gap is that the return type is not explicitly stated, but it is strongly implied by 'generate UUIDs'.

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 schema describes the only parameter 'count' with 'How many UUIDs (max 50)', providing 100% coverage. The description adds no extra parameter information, so the baseline of 3 is appropriate since the schema fully documents the parameter.

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 uses the specific verb 'Generate' with the resource 'random v4 UUIDs', clearly distinguishing this tool from siblings like generate_password and generate_hash. It explicitly specifies UUID v4, leaving no ambiguity about the output type.

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 such as generate_password or generate_hash. There is no mention of use cases, prerequisites, or exclusions, leaving the agent to infer when a UUID is needed.

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