generate_uuid

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

Describes standards compliance, entropy, and ordering characteristics. No annotations provided, so description carries full burden, which it meets well. Slight gap: does not mention if v1 includes MAC address exposure.

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?

Three concise sections (purpose, args, returns) with clear formatting. Every sentence adds value; no fluff.

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?

Tool is simple (1 param, no output schema), and description covers purpose, parameter semantics, and return value structure comprehensively.

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?

Despite 0% schema coverage, the description fully details the single parameter `version` with meanings, default, and trade-offs for each option.

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 the tool generates UUIDs and lists multiple use cases (database keys, idempotency tokens, etc.), distinguishing it from sibling tools like validate_email or dns_lookup.

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?

Provides explicit guidance on when to use each UUID version: v1 for time-sortable IDs, v4 for general-purpose, v7 for monotonic ordering and better database index locality.

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