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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool retrieves details, implying a read-only operation, but doesn't clarify aspects like authentication needs (e.g., whether the user_google_email must have access permissions), rate limits, error handling, or what happens if the page doesn't exist. The mention of 'Returns: str' in the description adds minimal value since an output schema exists, leaving significant gaps in behavioral context.

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 well-structured and appropriately sized, with a clear purpose statement followed by 'Args:' and 'Returns:' sections. Each sentence serves a purpose without redundancy, such as specifying required parameters and the return type. It could be slightly more front-loaded by integrating the parameter explanations into the main description, but overall, it's efficient and easy to parse.

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 tool's moderate complexity (3 parameters, no annotations, but with an output schema), the description is partially complete. It covers the basic purpose and parameters, and the existence of an output schema means it doesn't need to detail return values. However, it lacks usage guidelines and sufficient behavioral context (e.g., error cases, permissions), making it adequate but with clear gaps that could hinder an AI agent's effective use.

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 description lists the three parameters (user_google_email, presentation_id, page_object_id) and briefly explains their roles, such as 'The user's Google email address' and 'The object ID of the page/slide to retrieve.' However, with 0% schema description coverage, it doesn't fully compensate by providing detailed semantics like format examples (e.g., email validation, ID patterns) or interdependencies. This results in a baseline score, as the description adds some meaning but falls short of comprehensive parameter guidance.

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 clearly states the tool's purpose: 'Get details about a specific page (slide) in a presentation.' It specifies the verb ('Get details') and resource ('page/slide in a presentation'), making the intent unambiguous. However, it doesn't explicitly differentiate from sibling tools like 'get_presentation' or 'get_page_thumbnail', which is why it doesn't achieve 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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools such as 'get_presentation' (which might retrieve overall presentation details) or 'get_page_thumbnail' (which might provide visual previews), nor does it specify prerequisites or exclusions for usage. This lack of contextual direction limits its effectiveness for an AI agent.

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