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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds that results are paginated and shaped as {id, label}, which is useful, but it says nothing about ordering, page limits, or how cursors terminate.

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 tight sentence with the resource and return shape front-loaded and no wasted words. It is slightly under-specified rather than verbose, which keeps it short but leaves the agent wanting routing context.

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 parameters fully described and an output schema present, the description needn't explain return values. However, for a list tool sitting alongside four similar preset-related siblings, the absence of routing guidance is a meaningful gap.

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%, with limit, cursor, and category all documented in-schema. The description's 'pages through' hints at the cursor mechanism but adds no syntax or constraint detail beyond what the schema already provides, 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?

The description gives a specific verb and resource ('Pages through one preset category') plus the return shape ({id, label}), so the operation is unambiguous. It does not distinguish this from sibling tools like browse_presets, search_presets, or get_preset, 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?

There is no guidance on when to choose this over browse_presets, search_presets, list_preset_categories, or get_preset. The only implicit cue is the per-category scoping, which the required 'category' parameter already conveys.

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