receipt_products

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses only that login is required. It says nothing about whether the receipt must belong to the authenticated user, what happens with an unknown receipt_id, or whether results are paginated or filtered.

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 short, front-loaded sentences with no filler; the resource is stated first and the auth constraint second. The brevity is a virtue structurally, though it leaves content gaps addressed in other dimensions.

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?

An output schema exists, so return values need not be described, and the login requirement is flagged. For a one-parameter read tool that may be nearly sufficient, but the missing receipt_id semantics and absent sibling routing leave real gaps.

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 0% and the single parameter receipt_id is undocumented in the schema. The description does not compensate at all, never mentioning receipt_id or where its value comes from (presumably the receipts or receipt_detail tools).

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 fragment 'The line items of a digital receipt' tells an agent what resource is returned, but supplies no verb and no differentiation from close siblings such as receipt_detail and receipts. An agent must infer that this returns line items for a single receipt rather than a receipt summary.

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?

'Requires login' is an authentication prerequisite, not usage guidance. Nothing states when to pick this over receipt_detail, or what condition on receipt_id selects this tool.

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