klax_extract_pdf_links

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

The description adds useful behavioral detail: it targets both hyperlink annotations and raw URLs in body text, and organizes extraction by page. However, with no annotations at all, it does not disclose side effects, permissions, file prerequisites, or behavior when no links are present.

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 sentence with no filler; every phrase contributes information about what is extracted and how. It is compact and appropriately sized for a one-parameter tool.

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 simple one-parameter tool with an output schema, the description is minimally sufficient: an agent knows what the tool does and that file_path refers to a PDF lecture material file. It still lacks preconditions, usage guidance, and safety context, which matters because no annotations are provided.

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 single required file_path parameter has zero schema description coverage, and the description does not explain what value should be supplied. The phrase 'PDF 교안 파일' implies the target is a PDF file, but path format, source, and prerequisites are left unspecified.

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 states a specific verb and resource: it extracts clickable hyperlink annotations and URL text from PDF lecture-material files, page by page. It is clear in function and distinct from listing or downloading tools, though it does not explicitly name a sibling tool to differentiate itself from.

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 usage conditions, exclusions, or alternatives are provided. The description says what the tool does but not when to use it instead of a sibling like klax_analyze_material_links or klax_list_materials.

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