uuid_generate

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

With no annotations, the description carries the transparency burden. It correctly conveys that the tool generates v4 UUIDs and supports multiple results, but it does not explicitly state that the UUIDs are random, non-deterministic, side-effect-free, or how the output is shaped (string vs array).

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, front-loaded sentence with no filler. Every word contributes to the tool's purpose and basic capacity.

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 simple one-parameter utility with full schema coverage, the description is nearly adequate. However, with no output schema and no annotation, it leaves the return format ambiguous: whether a single UUID is returned as a string and multiple as an array, or whether the result is always an array. This is a meaningful gap for an agent deciding how to consume the result.

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% for the single 'count' parameter, including default and max. The description's phrase 'one or more' lightly reinforces the parameter but adds no meaning beyond what the schema already provides.

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 states a specific verb ('Generate') and a precise resource ('v4 UUIDs'), and indicates the tool supports multiple outputs via 'one or more'. It clearly distinguishes this tool from the unrelated sibling utilities.

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 purpose is so self-evident that usage context is implied clearly: call this whenever a v4 UUID is needed, with an optional count. No exclusions or alternatives are necessary given the sibling list contains no similar UUID-related tools.

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