generate_uuid

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

The note 'cryptographically secure' adds a safety-related behavioral trait beyond the schema. However, without annotations, the description does not disclose other relevant behaviors (e.g., idempotency, random vs. deterministic). It provides moderate transparency for a simple 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, front-loaded sentence with no unnecessary words. Every word serves a purpose: verb, resource, and security property.

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 generation tool with one optional parameter and no output schema, the description is adequate but does not specify the return format (e.g., array of UUIDs). This omits context that could affect downstream usage.

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 already covers the 'count' parameter with a complete description (1-100, default 1). The tool description adds no extra meaning for this parameter, so the baseline score of 3 applies given 100% schema coverage.

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 explicitly states 'Generate a cryptographically secure UUID v4', which clearly identifies the tool's specific verb ('Generate') and resource ('UUID v4'). It distinguishes from sibling tools like generate_nanoid or generate_password, which produce different outputs.

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 provided on when to use this tool versus alternatives (e.g., generate_nanoid for shorter IDs). The description does not specify constraints or exclusions, leaving the agent without context for selection.

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