Discounts_Retrieveadiscount

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

No annotations are present, so the description must carry the full burden. It only says 'Retrieve a discount' without disclosing if it is read-only, what happens if the discount does not exist, or why pagination parameters are present despite the singular retrieve name.

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 extremely concise at only three words, which is efficient but lacks sufficient detail for a tool with four parameters. It is front-loaded but not informative enough.

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?

Given the lack of output schema, annotations, and the presence of pagination parameters that seem mismatched with a singular retrieve, the description is incomplete. It does not explain how this tool differs from the list-all sibling or how to interpret the parameters.

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?

The input schema has 100% description coverage, but each parameter description is minimal ('Query parameter: ...'). The tool description adds no additional meaning beyond the schema, so it meets the baseline of 3.

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 states 'Retrieve a discount', which clearly indicates the action (retrieve) and resource (discount). It distinguishes from sibling tools like 'Discounts_Listalldiscounts' and 'Discounts_Createadiscount', but lacks specificity on how the discount is identified (e.g., by ID).

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?

No guidance is provided on when to use this tool versus alternatives like Discounts_Listalldiscounts. The description does not mention prerequisites or context such as needing a discount ID.

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