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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safe, local, informational nature of the call is covered structurally. The description adds the content covered by the call but says nothing about return format or length. Note that the annotation set is internally odd (destructiveHint=true on a read-only info tool), but the description does not contradict it.

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?

A single front-loaded sentence with a compact parenthetical enumerating the key features. Every clause carries information; no padding or repetition.

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 parameterless, non-destructive informational tool with no output schema, the description gives enough to know what the call will talk about. Only the expected form/length of the response is left unspecified, which is a minor gap.

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 tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline for a parameterless schema is 4. The description correctly implies the call is unconditional with no input required.

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 names the resource (OutfitMaker) and specifies exactly what the tool returns: an overview of the product and the benefits of connecting a closet, with concrete examples in parentheses. It is clearly distinguishable from the action-oriented siblings suggest_outfit and what_to_wear_today, though it never uses an explicit verb like 'explain' or 'describe'.

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?

Usage is only implied: an agent can infer this is the onboarding/informational entry point rather than a recommendation tool, but there is no explicit 'use this when the user asks what OutfitMaker is' guidance or reference to when the sibling tools are preferred.

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