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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=false and idempotentHint=false, so the safety and repeat-call behavior is covered structurally. The description adds the default range (1-100), which is useful, but says nothing about randomness quality, uniform distribution, or what the call returns.

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 short sentences with the core behavior front-loaded and the default appended. The wheel analogy is mildly decorative and overlaps a sibling's domain, but it costs little and aids intuition.

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 two-optional-parameter, side-effect-free tool with no output schema and full annotation coverage, the description supplies enough to invoke it correctly. Only the return shape and behavior on invalid ranges are unaddressed, which are minor gaps here.

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?

Schema description coverage is 100%, with both min and max documented as inclusive and given defaults, so the schema carries the parameter burden. The description only restates the inclusive range and default range, adding no syntax or edge-case semantics (e.g. what happens if min > max) beyond the schema.

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 gives a specific verb+resource ("pick a random whole number") plus scope ("inclusive range") and a default (1-100), so the effect is immediately understandable. It does not explicitly differentiate itself from the sibling spin_wheel, and the "like spinning a wheel" analogy actually overlaps with that sibling's vocabulary, which slightly muddies rather than sharpens the distinction.

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?

There is no guidance on when to use this rather than spin_wheel or get_wheel, and no exclusions or prerequisites. The agent must infer from the name and analogy that this is the no-wheel number generator.

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