Extract Pages From PDF

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

No annotations are provided, so the description must disclose behavioral traits like side effects and output. It only mentions the API endpoint and input format, but does not state whether the original file is modified, what the output is, or any authentication requirements. This is a significant transparency gap.

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 two sentences, front-loaded with the main purpose and followed by parameter details. It is concise, with no wasted words or redundant 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?

For a tool with 5 parameters, no annotations, and no output schema, the description covers input parameters but misses output behavior, error conditions, and side effects. It also lacks context about prerequisites like API keys. It is adequate but not complete.

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?

With zero schema description coverage, the description compensates by explaining pdf_file_path and page_numbers with concrete examples, and mentioning optional request_doc_name and output path settings. It covers all parameters, though it could be more explicit about output_dir and output_file_name.

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 'Extract selected pages from a PDF' with a specific verb and resource, making it easy to understand the core function. It distinguishes from sibling tools like delete_pdf_pages or split_pdf by focusing on extracting a subset of pages, not deleting or splitting.

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 implies use for extracting specific page ranges from a PDF into a new document, and the parameter examples provide clear context. However, it does not explicitly contrast with alternatives or state when not to use it, so it falls short of a 5.

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