generate_uuid

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

The description only mentions generation without detailing any behavioral traits like randomness, idempotency, or side effects. Annotations indicate readOnlyHint=false, which is consistent but offers no additional insight for a purely functional tool.

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 sentences: one for purpose, one for example. No redundant phrases, perfectly concise and 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 parameterless tool with no output schema, the description sufficiently explains what it does and provides an example. Could optionally mention UUID version for completeness, but not required.

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?

Input schema has zero parameters, so schema coverage is 100%. The description adds an example output but no parameter info, which is acceptable given no parameters exist. 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 'Generate a universally unique identifier (UUID)', using a specific verb and resource. It provides an example format, making the tool's purpose unmistakable and distinct from siblings like generate_ulid or 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 guidance on when to use this tool vs alternatives such as generate_ulid or generate_password. There is no mention of context, prerequisites, or scenarios where this tool is preferred or should be avoided.

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