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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safe read-only nature is covered. The description adds that this is a discovery/lookup aid for filter ids, which is useful context, but says nothing about pagination behavior despite page/per_page params existing.

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 enumeration; no wasted words. Slightly awkward punctuation but effectively concise.

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 described, and the description conveys the taxonomy types and purpose. For a simple read-only lookup tool with full schema coverage, this is largely complete, missing only explicit routing guidance.

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%, so the schema fully documents page, per_page, and the four taxonomy values. The description merely repeats the same taxonomy enum values already present in the schema, adding no format or selection nuance beyond it. Baseline 3 applies.

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 a specific resource (Chick-fil-A menu taxonomy terms) and enumerates the four taxonomy values, and the 'how to discover menu filter ids' clause clarifies the practical purpose. It is distinguishable from siblings like chick_fil_a_menu and chick_fil_a_menu_item, though no explicit verb (list/retrieve) is stated.

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 'how to discover menu filter ids' phrase implies the use case (a lookup step before filtering menu queries), but there is no explicit when-to-use or when-not-to-use guidance and no named alternative. Usage is inferable but not spelled out.

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