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

Annotations indicate readOnlyHint=false, but the description doesn't clarify if this implies state changes or side effects. It adds value by providing an example output format, but lacks details on generation method (e.g., version 4 random), uniqueness guarantees, or performance characteristics.

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, efficient sentence front-loaded with the core purpose, followed by a helpful example. Every word serves a purpose with no wasted text, making it easy to parse quickly.

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 simple, parameterless tool with annotations covering basic hints, the description is reasonably complete. It explains what the tool does and shows an output example, though without an output schema, it could benefit from clarifying the return type (e.g., string).

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?

With 0 parameters and 100% schema description coverage, the schema fully documents the input (none required). The description doesn't need to add parameter details, so it meets the baseline for this condition without redundancy.

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's purpose with a specific verb ('generate') and resource ('universally unique identifier (UUID)'), and provides a concrete example. It distinguishes itself from sibling tools like 'generate_ulid' or 'generate_token' by specifying UUID generation.

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?

The description implies usage for generating UUIDs but doesn't explicitly state when to use this tool versus alternatives like 'generate_ulid' or 'generate_token'. No guidance on prerequisites or exclusions is provided, leaving usage context to inference.

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