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 discloses the format structure (8-4-4-4-12) and that 'case' controls uppercase/lowercase, adding useful behavioral detail. However, it does not mention count behavior or output format, leaving some ambiguity for a generation 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?

The description is a single concise sentence that front-loads the core use case and includes key parameter semantics without unnecessary words. Every phrase contributes value.

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 low-complexity tool with no output schema, the description covers purpose and the main options, but it does not state whether the output is a single string or an array/list when 'count' is used. This is a notable gap for an agent invoking batch generation.

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?

The description adds meaning for two of three parameters: format ('uuid' vs 'guid') and case ('大小写' = case). It omits 'count', though the schema provides min/max/default for it. Since schema description coverage is 0%, the description partially compensates but not fully.

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 'UUID/GUID 批量生成' (batch generate UUID/GUID), naming the exact resource and action. It also distinguishes from sibling tools by specifying the UUID format variants (8-4-4-4-12 vs guid).

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 given about when to use this tool instead of alternatives, and no sibling tools or exclusions are mentioned. The description only explains what it does, not when it should be chosen.

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