office_pdf_parse

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

No annotations are present, so the description must disclose behavioral traits. It does not mention whether the tool is read-only, destructive, requires authentication, or has rate limits. The output format or side effects are not described, leaving the agent uninformed.

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 short (two lines) but lacks a purpose statement. While concise, it sacrifices essential information. It is not front-loaded with the tool's action, and the pricing/link are less critical for initial understanding.

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?

With no output schema and no annotations, the description must cover the tool's purpose, behavior, and return value. It completely fails to describe what the tool returns (e.g., parsed text, JSON), leaving a critical gap for the agent.

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 coverage is 100% with one parameter (fileUrl) described as 'PDF文件URL'. The tool description adds no additional meaning beyond the schema. Baseline score of 3 is appropriate since the parameter is self-explanatory, but the description does not enrich it.

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 only includes pricing and an API link, with no explicit verb or resource. 'PDF解析' is vague and does not clearly state what the tool does (e.g., extract text, layout, metadata). It barely distinguishes from sibling tools like office_pdf_merge.

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 is provided on when to use this tool versus alternatives. There is no mention of prerequisites, context, or exclusions. The description fails to help the agent decide when to invoke this tool.

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