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 the semantic linkage between term ids and chick_fil_a_content filters, but says nothing about pagination behavior, result shape, or whether the vocabulary is exhaustive.

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 tight sentences, zero filler, and the resource identity is front-loaded before the usage note. Nothing could be cut without losing information.

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, and the schema covers paging and taxonomy values. For a low-complexity taxonomy lookup, the description supplies what the agent needs, though a note on result size/paging semantics would fully close the loop.

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 taxonomy parameter already enumerates all valid values, so the schema does the heavy lifting. The description's category list is a human-readable restatement of the enum values, adding only marginal meaning over the schema.

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 concrete resource ('content vocabularies') and enumerates the vocabulary families (press, story, legal, downloadable-asset, campaign categories and tags), which is specific enough to distinguish it from chick_fil_a_content and chick_fil_a_menu_taxonomy. It stops short of a clean verb ('list/retrieve'), but the resource and scope are unambiguous.

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?

'Every term id is a filter value for chick_fil_a_content' gives clear downstream usage context, effectively telling the agent this is the discovery step feeding the content tool. There are no explicit when-not or exclusion statements, but the workflow context is stated rather than merely implied.

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