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

Annotations already declare readOnly, idempotent and non-destructive, so the safety bar is low; the description adds real behavior beyond them by disclosing that only published pages are returned and that omitting both params yields the complete catalog rather than a 25-item page. It does not say how results are ordered or what a page entry contains.

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 short sentences, zero padding, with the resource scope front-loaded and the pagination instruction following immediately. Every clause carries information an agent needs.

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 two-parameter, zero-required read tool with full schema coverage and rich annotations, the description covers scope, pagination and the unpaginated case. The only real omission is routing guidance relative to docs_search and docs_get.

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%, so both parameters are already documented, and the description adds mainly the interaction case: omitting limit and cursor together returns everything, resolving the schema's ambiguous 'defaults to 25 when paginating'. That is a modest value-add over the schema, fitting the baseline of 3.

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 and resource ('List published EvalGate documentation pages') plus a filter ('published'), which cleanly separates it from docs_get and docs_search by implication. It stops short of explicitly naming those siblings, so it is clear but not fully differentiated.

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?

Gives concrete invocation guidance for pagination ('omit both to list the complete catalog'), which is genuine when-to-do-what direction. However, it never states when to reach for docs_search or docs_get instead, leaving the sibling selection to inference.

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