GUID Generator

GUIDGenerator
Read-only

GUID Generator: GUID Generator is a GUID generator API that creates RFC 4122 version 4 GUIDs in standard, uppercase, hyphen-free, or brace-wrapped formats. Pass a count and formatting style to receive a batch of unique IDs matching your structural requirements. (Cost: 1 credit)

TDQS

B3.4/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, openWorldHint, and non-destructive behavior, so the safety profile is covered. The description usefully adds a cost disclosure ('Cost: 1 credit') and pins the algorithm version, but says nothing about uniqueness guarantees or randomness, which matter for an ID generator.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The content is compact and front-loaded, but the opening redundantly restates the name and title ('GUID Generator: GUID Generator is a GUID generator API'), wasting the most prominent position on repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter generator with an output schema and full annotation coverage, the description covers purpose, format options, batching, and cost. Nothing an agent needs to invoke it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3, but the description goes further by enumerating the four accepted format styles (standard, uppercase, hyphen-free, brace-wrapped), effectively supplying the enum that the schema lacks. It also clarifies that 'count' yields a batch of unique IDs.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource ('creates RFC 4122 version 4 GUIDs') and enumerates the supported output formats, so an agent immediately knows what it produces. It does not distinguish itself from close siblings such as UUIDGenerator or ULIDGenerator, which is the only real gap.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explains how to invoke the tool ('pass a count and formatting style') but never says when to choose it over UUIDGenerator, CuidGenerator, or ULIDGenerator, and offers no exclusions or prerequisites. Usage is only implied by the mention of batch generation.

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