Tool DescriptionsA

Average 4.2/5 across 1 of 1 tools scored.

Server CoherenceA
Disambiguation5/5

Only one tool exists, so there is no risk of confusion between tools. The single tool's purpose is clearly defined.

Naming Consistency4/5

With only one tool, naming consistency is not a concern. The name 'spinorflip' is descriptive but does not follow a verb_noun pattern, though it is not inconsistent.

Tool Count3/5

A single tool for generating a spinning wheel is borderline thin but fits the narrow purpose. The server would benefit from additional tools for related actions (e.g., history, customization), but it remains functional.

Completeness5/5

The single tool fully covers the server's declared purpose: generating a shareable spinning wheel with user-provided title, options, and optional background. No obvious gaps exist for this domain.

Available Tools

1 tool
spinorflipAInspect

Send a decision wheel to Spin or Flip and get a shareable spinning-wheel URL. Use this whenever a user wants to spin a wheel or make a random decision. Before calling this tool, generate the wheel yourself: pick a short title (2–6 words) and 6–12 options (1–4 words each) based on the topic. Optionally include a CSS linear-gradient background that matches the mood of the topic. Returns a URL the user can open to spin the wheel instantly.

ParametersJSON Schema
NameRequiredDescriptionDefault
titleYesShort wheel title, 2–6 words (e.g. "Best Pizza Styles", "Weekend Activities")
optionsYes6–12 options, 1–4 words each (e.g. ["Margherita", "Pepperoni", "BBQ Chicken"])
gradientNoOptional CSS linear-gradient matching the topic mood (e.g. "linear-gradient(135deg, #f97316 0%, #ef4444 100%)")
Behavior2/5

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

No annotations are provided, so the description must shoulder the full burden of behavioral disclosure. While it explains that the tool returns a URL, it omits critical behavioral traits: error handling if constraints are violated, idempotency, authentication needs, rate limits, or whether the tool modifies any state. Without this, an agent cannot fully predict the tool's side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact (four sentences) and front-loaded: the first sentence states the core action and result, the second clarifies usage context, the third gives preparation instructions, and the fourth covers optional input. No unnecessary words; every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no annotations, no output schema, and only 3 parameters, the description covers the main aspects: what the tool does, when to use it, what inputs are needed (with constraints), and the output (a URL). It lacks details on error messages, rate limits, or what 'Spin or Flip' is, but these are minor given the tool's simplicity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description adds value by providing concrete examples ('Best Pizza Styles', 'Margherita'), specifying word count limits (2–6 for title, 1–4 for options), and explaining the gradient's purpose ('matching the topic mood'). This contextual enrichment justifies a score above baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states that the tool sends a decision wheel to Spin or Flip and returns a shareable URL. It explicitly says 'use this whenever a user wants to spin a wheel or make a random decision,' which directly identifies the tool's purpose. This is a specific verb+resource combination, and there are no sibling tools to differentiate from.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit guidance on when to use the tool ('whenever a user wants to spin a wheel or make a random decision') and detailed prerequisites: 'generate the wheel yourself: pick a short title (2–6 words) and 6–12 options (1–4 words each).' It also notes optional gradient inclusion. This covers preparation and context excellently.

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