generate_uuid

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

Description indicates creation but provides no additional behavioral details beyond the action. Annotations show readOnlyHint=false, consistent with creation. No contradictions, but lacks info on uniqueness guarantees or randomness source.

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?

Two concise sentences with an illustrative example. No extraneous information, perfectly sized for the tool's simplicity.

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?

The example output fully clarifies the return format. With no output schema, this is sufficient for a tool with zero parameters and a well-known return value.

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?

No parameters, so description cannot add parameter details. Baseline 4 applies as per rules; the description correctly implies no inputs are needed.

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?

Description explicitly states it generates a UUID and provides a concrete example. No ambiguity, clearly distinguishes from other generation tools like generate_ulid and generate_token.

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 explicit guidance on when to use vs alternatives. However, for a straightforward tool like UUID generation, it is generally clear. Could mention that generate_ulid or generate_token are alternatives for different needs.

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