generate_uuid

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

The description is extremely minimal and does not disclose behavioral traits beyond the basic action. With no annotations provided, the description fails to mention that the tool is stateless and non-destructive, or that it generates a random UUID (v4) by default. The agent must infer behavior from the schema.

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 with no wasted words. It is front-loaded with the key verb and resource. While extremely short, it is concise for a simple tool, though slightly more contextual information could be added without losing conciseness.

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 (2 optional params, output schema exists), the description is minimally sufficient but lacks completeness. It does not explain the output format (e.g., a string) or mention that the default version is 4 and uppercase false. With an output schema present, the description could be slightly richer.

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?

Schema description coverage is 100%, so the schema already documents both parameters (version and uppercase) with defaults and descriptions. The description adds no additional semantic value beyond what is in the schema. Baseline 3 is appropriate.

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 action ('Generate') and the resource ('UUID'). It distinguishes from sibling tools like generate_password or generate_hash by specifying the exact output format. However, it could be improved by mentioning the default version or typical use cases.

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. While the purpose is clear, there is no mention of context, such as when to choose UUID v1 vs v4, or how it differs from other generation tools like generate_random_string.

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