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

The description indicates it produces a random UUID, implying non-deterministic output. It mentions a free trial limit per signed wallet, hinting at authentication or rate limiting, but does not describe any potential side effects or state changes. Since there are no annotations, this limited transparency is acceptable but not thorough.

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 clauses: one stating purpose, one stating usage limit. No unnecessary words or 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?

Given the trivial nature of generating a UUID, the description is complete. It states what it does and a usage restriction. It does not specify output format, but this is implied by the tool name and description.

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 input schema is empty with no parameters, so the description adds no parameter-specific detail. The schema covers all parameters (none), so the description need not elaborate. Baseline score applies.

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?

Clearly states the tool generates a crypto-random UUID. The phrase 'Crypto-random UUID' is unambiguous and immediately conveys the primary function.

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 no guidance on when to use this tool versus alternatives, nor any context for use cases. The only additional note is a rate limit, not usage instructions.

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