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

Annotations already cover read-only and open-world safety, so the description's job is lighter. It adds useful behavior context: the response bundles featured offers, offer counts and similar stores, and pagination is revealed through total_pages in the result — details not present in the annotations.

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 with zero filler; the payload description comes first and the slug/pagination guidance follows. Nothing is wasted.

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 need not document return values, and the slug prerequisite plus pagination hint make it actionable. Slightly more sibling differentiation would make it fully complete.

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 both parameter descriptions already state the slug source and the 24-offers-per-page pagination. The description reinforces this but adds essentially no syntax or format detail beyond the schema, so the baseline 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?

States a specific verb ('Get') and enumerates the exact payload — featured offers, offer counts, similar stores — on one RetailMeNot category page. It also pins the input to a slug sourced from retailmenot_categories, which separates it from the categories-listing sibling.

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 tells the agent where to obtain the slug (retailmenot_categories) and when to use the 'page' parameter (later offer pages, driven by total_pages). No explicit when-not-to-use or exclusion against the store/deal siblings, so it stops 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.
