PDF Export for AI Agents

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It describes a read-only informational operation ('Get usage tips and upgrade info'), which implies it's safe and non-destructive, but it doesn't specify any behavioral traits like authentication needs, rate limits, or what the output format might be (e.g., text, structured data). This leaves significant gaps for an agent to understand how to interact with it effectively.

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 extremely concise and front-loaded, consisting of a single, clear sentence that directly states the tool's purpose without any wasted words. Every part of the sentence earns its place by conveying essential information.

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 complexity (a simple informational tool with one optional parameter) and the lack of annotations and output schema, the description is incomplete. It doesn't explain what the tool returns (e.g., the format or content of the 'usage tips and upgrade info'), which is critical for an agent to use it correctly. The schema covers the input well, but the output remains unspecified, making the overall context insufficient.

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 input schema has 100% description coverage, with the 'topic' parameter fully documented in the schema (including optional nature and available values). The description doesn't add any meaning beyond what the schema provides, as it doesn't mention parameters at all. With high schema coverage, the baseline score of 3 is appropriate, as the schema does the heavy lifting.

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 with a specific verb ('Get') and resource ('usage tips and upgrade info for PDF Export'), making it immediately understandable. However, it doesn't explicitly differentiate from its sibling tool 'pdfcrowd_create_pdf' (which presumably creates PDFs rather than providing information), so it misses the highest 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 the sibling tool or any other context for usage, leaving the agent to infer based on the tool name and description alone.

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