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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so safety is well covered. The description adds only the filter capability and says nothing about pagination behavior, ordering, or result limits that the annotations do not cover.

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 front-loaded sentence with no wasted words. The odd token 'seliee_pages' slightly reduces readability, but structure and length are appropriate.

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 4-parameter list tool with 0% schema coverage and no output schema, the description should at minimum explain pagination and what a page record looks like. It leaves the agent guessing about page/per_page semantics and return shape.

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 0%, so the description carries full burden, yet it only names website_id and website_uuid. The page and per_page pagination parameters (with defaults 1 and 50) are entirely undocumented anywhere, so half the parameters remain opaque.

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 ('List') and resource ('seliee_pages') and adds the filtering capability, so the operation is unambiguous. It does not explicitly contrast with siblings like get_page or list_websites, but the plural-list framing distinguishes it adequately.

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 word 'optionally' hints at filtering, but there is no guidance on when to use this versus get_page, list_websites, or the update_page_keys family, and no prerequisites or exclusions are given.

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