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

Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds meaningful behavioral context beyond that: bodies are large and therefore opt-in, default rows contain titles/links/dates/excerpts, downloadable assets have a title and link rather than a body, and only press-room/story have tag vocabularies.

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?

It is a compact block of sentences with the core 'List a page of...' purpose front-loaded, followed by type semantics, body opt-in, and routing. Every sentence carries useful information, with little filler.

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 re-explained, and the description covers the notable quirks (body opt-in, downloadable-asset shape, tag scope) plus sibling routing. It is complete for correct invocation, though it does not address pagination behavior beyond what the schema states.

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 baseline is 3. The description goes beyond the schema by enumerating the type values inline, explaining the rationale for include_body (bodies are large), and noting the tag-vocabulary restriction to press-room and story.

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: 'List a page of Chick-fil-A editorial content.' It clearly distinguishes itself from the content-oriented siblings by naming chick_fil_a_content_taxonomy and chick_fil_a_menu as separate tools, so an agent can route without ambiguity.

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?

It gives explicit routing: use chick_fil_a_content_taxonomy to discover category/tag values and chick_fil_a_menu for menu items. It also implies when include_body is warranted (bodies are large). It lacks an explicit when-not-to-use statement, so it falls just short of a 5.

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