UUID Generator

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

With no annotations provided, the description carries the full behavioral burden. It explicitly discloses the key behavioral trait—randomness—and specifies the UUID version. It implies a simple, non-destructive generation operation with no hidden side effects, which is appropriate for this tool.

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?

A single front-loaded sentence that states action, result type, randomness, and multiplicity with no filler. Every element in the description earns its place.

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, side-effect-free generator, the description is sufficient for selection and invocation. The only minor gap is that the return shape for multiple UUIDs (e.g., separate strings vs. list) is not explicit, but no output schema exists and the intent is fairly inferable from the count parameter.

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 already fully documents the count parameter, including defaults, min, and max, so the description does not need to add parameter syntax. The phrase 'one or more' adds slight semantic reinforcement but not meaningful new information beyond the schema.

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 specific action (generate), the exact resource (random v4 UUIDs), and the optional multiplicity. It differentiates the tool from sibling generators like base64, hash, or slugify by naming the UUID format and version.

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?

The description gives clear context: use this when you need random v4 UUIDs. None of the sibling tools offer UUID generation, so explicit when-not-to-use guidance is unnecessary and no exclusion is misleading.

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