Behavior2/5

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

With no annotations, description must fully disclose behavior. It mentions downloading and previewing but omits important details like rate limits, network dependency, failure modes for broken links, or handling of non-PDF extensions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence is concise but lacks structure; parameter information is absent and necessary details are omitted. Not all sentences earn their place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 7 parameters and no output schema, the description is severely incomplete. It fails to explain input semantics, return value format, or error handling, leaving the agent underinformed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0% and description adds no parameter meaning. It does not explain what 'mirror_1', 'title', or optional fields (author, year, etc.) represent or how they affect the operation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the tool resolves mirror links, downloads a PDF, and returns a preview, which is specific and distinguishes it from sibling tools like 'search_libgen' or 'download_scihub_paper'. However, the verb 'inspect' is vague without the description's context.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives (e.g., after searching LibGen). Lacks explicit context, exclusions, or mention of prerequisites like prior search results.

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