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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It only says 'Fetch normalized metadata' without mentioning any behavioral traits such as network dependency, rate limits, or idempotency. The output schema covers return format, but other aspects like execution behavior are opaque.

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 one sentence that efficiently conveys the tool's purpose and input formats without any redundant words or filler.

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 tool with one parameter and an output schema, the description provides the essential information. However, it could mention that metadata is normalized or hint at the output structure. Missing behavioral details like caching or network calls, but overall sufficient.

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 description coverage is 0%, but the description adds meaning by specifying that the single parameter can be an arXiv ID, abs URL, or PDF URL, which clarifies the accepted formats beyond the schema's generic 'Arxiv Id Or Url' title.

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 verb 'Fetch' and the resource 'normalized metadata for a specific arXiv paper'. It specifies three input formats (arXiv ID, abs URL, PDF URL), which distinguishes it from sibling tools like download_arxiv_pdf or read_arxiv_paper.

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 usage when you have an arXiv identifier or URL and need metadata, but it does not explicitly state when to use this tool over siblings like search_arxiv or get_semantic_scholar_paper. No when-not-to-use guidance is provided.

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