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 a genuinely useful behavioral trait beyond them: this tool returns filter IDs that are consumed as inputs by other tools, framing it as a lookup step in a chain. It omits pagination/result-shape behavior, though page and per_page are documented in the schema.

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 sentences with zero filler; the purpose is front-loaded and the follow-up routing instruction follows immediately. 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?

With an output schema present, return values need not be explained, and the description covers purpose, taxonomy scope, and downstream usage. What's missing is minor: that taxonomy is required (a hard selection decision) and that results are paginated, both of which the schema already supplies.

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% (page, per_page, and the four taxonomy values are all documented), so the baseline is 3. The description's phrase 'menu, item-type, group, and nutrition-table filters' loosely mirrors the taxonomy parameter but adds no syntax or format detail beyond what the schema already states.

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 verb and resource ('List Chick-fil-A menu taxonomy terms') and enumerates the four taxonomy families, so the agent knows exactly which categories it can discover. The name and wording also differentiate it from the sibling chick_fil_a_content_taxonomy, and the second sentence names chick_fil_a_menu and chick_fil_a_menu_item as the consumers of its output.

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 second sentence gives concrete routing guidance: pass the returned filter IDs to chick_fil_a_menu or chick_fil_a_menu_item, making this a prerequisite/discovery step rather than a menu-fetching tool. It names alternatives and their relationship but gives no explicit when-not-to-use or prerequisite conditions (e.g., that taxonomy is required and must be picked first).

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