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

With no annotations provided, the description carries full burden for behavioral disclosure. It adds valuable context about the randomness quality ('cryptographically secure'), but doesn't describe important behavioral aspects like whether the selection is weighted, what happens when count exceeds choices length, default behaviors, or error conditions. The description provides some behavioral insight but leaves significant gaps.

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 that communicates the core functionality without unnecessary words. It's appropriately sized for a simple selection tool and front-loads the essential information. Every word earns its place in conveying the tool's purpose and quality characteristic.

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 3 parameters with 0% schema coverage, no annotations, and no output schema, the description is insufficiently complete. While it clearly states what the tool does, it provides no guidance on how to use it effectively - missing parameter explanations, return value information, error handling, and practical usage examples that would help an agent invoke it correctly.

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% schema description coverage and 3 parameters, the description provides no information about any parameters. It doesn't mention the 'choices' array, 'count' integer, or 'allow_duplicates' boolean parameter at all. The description fails to compensate for the complete lack of schema documentation, leaving all parameters semantically undefined.

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 ('Randomly select') and resource ('items from a given list'), and distinguishes it from siblings by focusing on list selection rather than generating specific data types like booleans or integers. It adds the important detail of 'cryptographically secure randomness' which differentiates it from basic random selection tools.

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 context through 'cryptographically secure randomness' which suggests security-sensitive applications, but doesn't explicitly state when to use this tool versus the sibling tools. No alternatives or exclusions are mentioned, leaving the agent to infer appropriate usage scenarios based on the tool's name and description alone.

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