document_to_pdf

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

No annotations provided; description only states basic conversion. Does not disclose side effects, authentication needs, or behavior beyond what is obvious.

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?

Single sentence with core purpose and reference URL. Front-loaded with supported formats, but could be more concise or add brief usage tips.

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 7-parameter tool with no annotations or output schema, the description lacks context on return value, error handling, and when to prefer sibling tools.

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 covers all 7 parameters with descriptions. Description adds no parameter-specific meaning beyond listing file formats and a reference URL.

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?

Clearly states conversion of many document types to PDF, listing formats and referencing documentation. Distinct from sibling converters like csv_to_pdf or image_to_pdf.

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 on when to use this vs specialized tools (e.g., csv_to_pdf, image_to_pdf). Only implies usage by listing formats, but lacks exclusions or alternatives.

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