culvers_flavor

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

With no annotations provided, the description carries the full behavioral burden. It discloses that this is a read operation returning a single flavor's full details, and it enumerates meaningful return components. It also provides the upstream endpoints for the slug, which is useful behavioral and data-provenance context beyond what the schema alone offers.

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 two sentences with no filler. The action and return highlights are front-loaded, and the parameter sourcing guidance is placed at the end where it complements, not obscures, the core purpose.

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 single-parameter detail tool with no annotations and no output schema, the description is sufficient. It tells the agent what the tool returns, what data is included, and exactly where to obtain the required slug, so there is no critical missing information for correct invocation.

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 coverage is 100% and the schema already describes the slug as coming from /culvers/calendar or /culvers/store. The description adds extra value by naming the exact field paths (flavors[].slug and flavors_of_the_day[].slug), which gives the agent precise guidance on where to extract the parameter.

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 opens with a specific verb and resource: "Get one Culver's Fresh Frozen Custard flavor's detail." It then specifies what the detail includes (allergens, ingredient breakdown, category labels), which clearly distinguishes this detail endpoint from the list-style sibling tools like culvers_calendar and culvers_store.

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 gives clear usage context by stating that the slug comes from GET /culvers/calendar or GET /culvers/store, which tells the agent how to obtain the required input. It does not explicitly state when not to use this tool or compare it to culvers_item/menu, so it stops short of a full when/when-not explanation.

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