jumbo_get_shopping_list

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

With no annotations, the description carries the full disclosure burden, and it does add value by spelling out the exact return contents (active status plus per-item fields). It remains silent on auth/permission requirements despite a jumbo_login sibling, and on error or empty-list behavior, so it is adequate but not rich.

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 sentence that front-loads the verb and resource and then lists return contents without waste. The Dutch alias ('lijstje') is a cheap, useful disambiguation for a domain-specific name.

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?

There is no output schema, so the description correctly takes on the job of describing the return payload, which it does thoroughly. Only minor gaps remain: no statement of auth requirements or behavior when the list is empty or inactive.

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 tool takes zero parameters, which is the baseline-4 case; the description correctly implies no filtering or identifier input is needed. There is nothing further for it to document.

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 ('Get the user's Jumbo shopping list') and goes further by enumerating the returned payload (active flag, item id/term/sku/completed), which makes its role as the read-side counterpart to the add/remove/set siblings obvious. It never names those siblings explicitly, so it falls short of a 5.

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?

The description gives no when-to-use, when-not-to-use, or alternative tool guidance. An agent can infer it is the read operation for the shopping list, but nothing states prerequisites (e.g. that jumbo_login may be required) or when a different listing tool is preferable.

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