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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds useful scope context about the data window ('whole published window, roughly two months forward'), which is genuine added value, but it says nothing about ordering, coverage gaps, or freshness beyond that.

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 no filler. The resource and its scope are stated immediately, and every clause earns its place.

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?

An output schema exists, so return values need not be explained. For a one-parameter read tool the description covers what the resource is and how far forward it reaches, though it could clarify relationship to the single-flavor sibling to be fully complete.

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% and the slug parameter already documents its source (/culvers/directory), so the schema carries the load. The description adds no additional parameter meaning, which is the expected baseline when coverage is complete.

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?

States a specific resource (per-restaurant flavor-of-the-day and daily soup schedule) with scope (whole published window, ~two months forward). It is clearly distinguishable from a single-flavor tool, but it does not explicitly name or contrast with its sibling culvers_flavor or 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?

There is no when-to-use guidance or mention of alternatives. The agent must infer that this is the tool for a forward-looking schedule rather than a single flavor lookup, and nothing tells it when to prefer culvers_flavor or culvers_store instead.

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