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

Annotations already establish read-only, non-destructive, closed-world behavior, so the bar is lower; the description still adds real value by naming response metadata (total/last_page) that drives pagination and disclosing the plan gate on partial submissions. It does not describe the shape of an individual submission record, which matters somewhat given there is no output schema.

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 the core action first, then pagination mechanics and the plan constraint. Nothing is redundant or padded; every clause carries operational information.

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 6 fully documented parameters, safe-read annotations, and an explicit note about the pagination fields returned, an agent has enough to call this correctly and iterate. The residual gap is the record-level return shape, which the description leaves to runtime inspection.

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 each parameter (page, per_page, sort_by, sort_by_order, is_complete, form_slug) is documented inline, so the baseline is 3. The description's only parameter-relevant content is the pagination cue and the PRO constraint on incomplete submissions, which largely restates what the is_complete schema entry already says.

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?

"Fetch a page of a form's submissions for analysis" gives a specific verb (fetch) and resource (a form's submissions), scoped to a single form. It is unambiguous and clearly distinct from the form-level siblings (list-forms-tool, get-form-tool), though it never names a sibling or states the contrast explicitly.

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?

It tells the agent how to page (read total/last_page from the response and request further pages) and gives a prerequisite: partial submissions require a PRO plan. There is no explicit when-not-to-use or alternative-tool routing, but no sibling overlaps this resource, so the practical gap is small.

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