get_document_info

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

No annotations are present, so the description must carry behavioral disclosure. It signals a read-only operation via 'Get' and lists the returned information, but it does not describe exact return structure, metadata scope, error behavior, or any side effects. This is adequate for a simple getter but has clear gaps.

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 a single, efficient sentence with a clear verb and object. It contains no filler and every word contributes to understanding the tool's purpose.

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 zero-parameter read-only retrieval tool, the description provides the essential purpose and output contents. The absence of an output schema makes 'metadata' somewhat vague, but the simplicity of the tool means few additional details are needed for correct invocation.

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 tool accepts zero parameters, so the description has no parameter meanings to explain. The schema is empty and the description still adds value by indicating what information the agent will receive.

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 uses a specific verb ('Get') and resource ('document'), and enumerates what is returned: name, pages, and metadata. It is clear but does not explicitly distinguish this tool from the many sibling getter-style tools, so it stops short of a perfect score.

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?

No guidance is provided about when to use this tool versus sibling tools such as page_overview, get_nodes_info, or similar read operations. With a large sibling list and no alternative selection hints, an agent is left to infer the right context.

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