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

With no annotations, the description does useful work by disclosing visibility and access semantics: owned, enterprise-managed, and shared scopes, Business owner control, and that ordinary shares do not reveal private pages. It also states that slim metadata is returned by default, though it does not discuss pagination or response limits.

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?

The description is compact and front-loads the core listing behavior before adding access and filtering details. The enterprise-owner sentence is somewhat specialized, but it remains relevant and does not bloat the definition.

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 read-oriented list tool with no annotations and no output schema, the description covers visibility scope, default return mode, and key filtering behavior. It is mostly complete, with only minor gaps around pagination and full return-shape expectations.

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 the schema already defines all three parameters. The description still adds meaning, especially by mapping folder_id to project filtering and clarifying that include_shared=false omits ordinary shared pages.

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: it lists pages and scopes them to owned, enterprise-managed, and shared pages. It is clear what the tool does, but it does not explicitly differentiate itself from nearby siblings such as search_pages or get_page_tree.

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 description provides some usage context by explaining folder_id filtering and include_shared=false for omitting ordinary shared pages. However, it does not explicitly say when to choose this tool over search_pages, get_page_tree, or other listing/search siblings.

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