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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered upstream. The description adds the useful detail that the payload includes Elementor template type, but says nothing about pagination behavior beyond the schema, result caps, or whether unpublished/draft items appear.

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 zero filler. The scope constraint comes first and the return-field inventory second, which is exactly the order an agent needs for a list operation.

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 no-required-parameter list tool whose annotations carry the safety profile, the description covers what the tool returns and what it covers. It is slightly thin on routing versus the many sibling list tools, but nothing critical for invoking it correctly is missing.

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%, so page, site_id, per_page, and post_type are already documented in-schema; the baseline is 3. The description adds nothing about parameter semantics beyond listing output fields, so no credit above baseline is warranted.

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 a scoped resource (pages/posts built with Elementor), and enumerates the returned fields, which lets an agent distinguish it from the generic wp_list_pages at a glance. It never names the sibling, so differentiation is implied by the Elementor qualifier rather than stated 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?

There is no guidance on when to pick this over wp_list_pages, divi_list_pages, or elementor_list_templates, which all return page-like resources. The description never states prerequisites, exclusions, or the alternative to choose for non-Elementor content, so the agent must infer selection from the tool name alone.

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