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: this returns published help-center content rather than account- or order-specific state, which is a meaningful behavioral constraint beyond what annotations provide. It doesn't discuss pagination limits or result determinism, but the annotation bar is lower here.

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 efficient sentence front-loads the operation, then bounds scope, then routes to alternatives. No waste, no repetition.

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, the description needn't detail return values. Combined with annotations covering the safety profile and a 100% documented schema, the description is complete for an agent to call this tool correctly and choose it over siblings.

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 coverage is 100% (both limit and offset have descriptions with ranges and defaults in the schema), so the description's mention that limit/offset paginate public content is redundant with the structured fields. Baseline 3 is appropriate since the schema does the heavy lifting.

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 ('Fetch a page of Popeyes' published customer-support FAQ question/answer records'), with explicit scope ('public help-center content, not account- or order-specific state'). It also names the siblings it is not, so an agent can distinguish it from popeyes_menu and popeyes_offers without opening schemas.

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?

Explicitly contrasts this tool with two siblings: use popeyes_menu for menu items and popeyes_offers for deals. The scope exclusion ('not account- or order-specific state') tells the agent when this tool is not appropriate, leaving nothing to inference.

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