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

Annotations already declare this safe and read-only, but the description adds genuinely useful context beyond them: the exact nature of the payload (owner-defined fields plus accepted consent text), a personal-data handling warning, and the pagination model. It does not describe default limits or ordering, which limits it below a 5.

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?

Three tight fragments with no filler, and the resource identity is front-loaded before the privacy note and pagination hint. The telegraphic style is slightly clipped but nothing is wasted.

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 no output schema, the description usefully characterizes the return payload and pagination, and flags the sensitivity of the data. It is reasonably complete for a read-only list tool, though undocumented parameters and an unstated default page size leave minor 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 coverage is 0% – qrId, limit, and cursor carry no descriptions anywhere. The description only gestures at pagination ('Cursor-paginated'), giving no meaning for the required qrId or the limit bounds, so it fails to compensate for the documentation gap.

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 names the concrete resource ('submissions from a lead_form QR's page') and enumerates the key content (owner-defined fields plus consent text), so an agent knows exactly what is returned. It stops short of explicitly contrasting with siblings such as leads_delete or scans_list/feedback_list, so differentiation is left to inference.

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?

There is no when-to-use statement, no prerequisites, and no mention of the related leads_delete sibling or any alternative for retrieving lead data. The only faint usage cue is 'Cursor-paginated', which describes mechanics rather than selection guidance.

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