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

With no annotations, the description carries the full behavioral burden, but it only says 'create' and gives a use case. It fails to disclose whether the call appends to or replaces existing nodes, how seo.status values like keep/redirect/delete are honored, or what happens on partial failure. This is a meaningful gap for a bulk mutation tool.

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 sentences, with the core action front-loaded and the use case in the second sentence. Every phrase adds information and there is no filler or repetition of schema details.

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?

Given the deeply nested nodes schema and the absence of an output schema or annotations, the description is too thin to be fully actionable. It does not explain return values, error behavior, or how the tool treats existing pages vs new pages. The agent can infer field semantics from the schema but not the overall execution model.

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?

The schema already documents all parameters with 100% coverage, so the description is not required to restate them. It adds useful conceptual context by linking the tree structure to temp_id/parent_temp_id and mentioning zoning, entry points, CTAs and tags, which map to schema properties. This justifies the baseline score without exceeding it.

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 ('Create multiple pages') and resource ('tree structure'), and immediately conveys the bulk nature that separates it from create_node. The mention of sitemap, zoning, entry points, CTAs and tags clarifies what kinds of nodes are expected. Minor ambiguity between 'pages' and 'nodes' is not enough to obscure the purpose.

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 phrase 'Create multiple pages at once' signals the batch use case, and 'Ideal for generating a full sitemap' gives a concrete scenario. It does not explicitly name alternatives like create_node for single-node creation or say when not to use it, so it stops short of full routing guidance.

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