Generate UUIDs

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 only states the tool generates UUIDs, but does not confirm that the operation is random, idempotent, side-effect-free, or deterministic. Additional traits like return format or required permissions are omitted.

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, concise sentence that conveys the core purpose and parameter range without any extraneous information. Every word earns its place, and the structure is front-loaded with the key action.

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 tool with one optional parameter, no annotations, and no output schema, the description is mostly complete but lacks clarification on the return format (e.g., 'Returns a JSON array of UUID strings'). The agent might infer this from the name, but completeness warrants explicit mention.

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 0%, so the description must compensate. It explains that the 'count' parameter controls the number of UUIDs generated (1–100), which aligns with the schema constraints. While it doesn't mention the default value (1) or the exact return format, it provides essential semantic context beyond the raw 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 tool generates RFC-4122 version-4 UUIDs, with a specific count range (1–100). It uses a specific verb ('Generate') and resource ('RFC-4122 version-4 UUIDs'), distinguishing it from sibling tools which handle data transformation, hashing, or JSON manipulation.

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. The description is purely functional and does not mention context, prerequisites, or exclusions. Sibling tools suggest different purposes (e.g., hashing, JSON), but the description offers no explicit comparison.

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