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

Even without annotations, the description discloses key behavioral traits: it returns a paginated page, is public CMS content, exposes only the fixed points cost, and does not include per-account/per-order restrictions. It could be slightly more explicit about read-only guarantees or exact return shape, but the "List" framing plus these limitations carries most of the burden.

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?

The description is four sentences, all dense with useful information: scope, example, sibling differentiation, and data limitations. There is no filler, and the core purpose is front-loaded.

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?

For a simple optional-parameter list endpoint, the description covers scope, pagination intent, public-vs-member data, and output semantics for the points field. The lack of an output schema means it doesn't enumerate the full return structure, but "Returns a page" plus the described fields is adequate for correct invocation.

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%, and the parameters (limit, market, offset) are fully documented in the schema. The description adds no parameter-level detail beyond what the schema already provides, so the baseline of 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 opens with a specific verb and resource: "List Popeyes Rewards' points-redemption catalog," then gives a concrete example ("600 points for Cheese Bites"). It explicitly distinguishes itself from sibling tools like /popeyes/offers, /popeyes/quests, and /popeyes/promotions, so an agent can tell exactly what this endpoint does.

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 explicitly names sibling alternatives and what they cover (priced deals, challenges, bonus-points campaigns), and clarifies that this is "public CMS content" rather than a signed-in member's balance or redemption history. This gives the agent clear when-to-use and when-not-to-use signals.

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