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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It correctly characterizes the operation as informational and adds the non-obvious fact that gift cards are valid at every location. It doesn't specify whether the response is a list, but for a zero-parameter info tool this is a minor gap.

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, each with a distinct job: the first defines the tool's scope, the second adds a relevant validity fact. There is no filler, repetition, or unnecessary detail.

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 zero-parameter, read-only info tool with no output schema, the description covers all essential details an agent needs to decide to call it and interpret the result. The included topics plus the validity fact make the tool self-explanatory.

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?

There are zero parameters, so the schema imposes no burden. The description orients the agent to the content domains (amounts, languages, where to buy) that the tool will return, effectively substituting for parameter documentation.

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 'Information about Floreal Holidays gift cards' and enumerates the specific aspects covered: amounts, languages, and where to buy. This makes it immediately distinguishable from sibling tools like get_faq or get_menu, none of which deal with gift cards.

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 explicit 'use this when' wording, but the description makes the context obvious: any question about Floreal gift card amounts, languages, or purchase locations. Since no sibling tool overlaps with gift card topics, no exclusions or alternatives are needed.

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