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

Annotations already declare readOnlyHint=true, so the safety profile is covered. Beyond that, the description usefully discloses that there are no paging or filter parameters, preventing an agent from attempting unsupported pagination, and notes the entry keying by field API ID. It stops short of describing auth needs or rate limits.

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 efficient sentences plus the endpoint reference, front-loaded with what the entries are. Slightly dense but no filler; the no-paging note earns its place.

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 read-only list tool with no output schema, the description conveys enough: what the return contains (report entries as a datagrid/export would show, keyed by field API ID) and the absence of paging/filtering. Would benefit from a pointer to the sibling used for filtered or labeled retrieval.

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 100%, and the schema itself documents both parameters, including that 'system' pulls IP/payment metadata and that 'report' accepts a hash or URL title with a cross-reference to wufoo_list_reports. The description adds nothing new about parameters, so 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+resource (list report entries) and adds real meaning with 'what its datagrid widget or an export would show, keyed by field API ID,' which clarifies the data shape. It distinguishes the resource from form entries by noun, but does not explicitly contrast with siblings like wufoo_list_form_entries or wufoo_get_labeled_entries.

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 statement of when to use this versus alternatives. The only constraint given is that Wufoo documents no paging or filter parameters, which is a limitation note, not routing guidance. An agent gets no help choosing between this and wufoo_get_labeled_entries or wufoo_list_form_entries.

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