validate_arxiv_input

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions normalization and returning a 'safe next action' but does not explain what 'safe next action' means, whether the tool performs network access, or whether it has side effects. The behavior is only superficially disclosed.

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, front-loading the verb 'Normalize' and the resource. Every word contributes to the stated purpose. It is an example of concise, well-structured writing, even though additional detail is needed elsewhere.

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?

Given no output schema and no annotations, the description is insufficient for an agent to understand the return value 'safe next action' or how to interpret it. It also lacks context for when to call this tool in a workflow, especially with validate_arxiv_request so close in name and purpose. The agent cannot confidently select and invoke the tool correctly based solely on this description.

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%, so the description must compensate. It does map 'arXiv ID' to text_id and 'URL' to url, which is helpful, but it does not explain whether the parameters are mutually exclusive, which takes precedence, or what formats are accepted. Both parameters are optional, and the description gives no guidance on how to choose between url and text_id.

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 uses the specific verb 'Normalize' and names the resource 'arXiv ID and URL inputs', clearly stating the tool's purpose. It also mentions the outcome 'return the safe next action,' which adds specificity. However, it does not differentiate from the similarly named sibling validate_arxiv_request, so it is clear but lacks sibling differentiation.

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 provides no guidance on when to use this tool versus alternatives. It says nothing about preconditions, what input state is expected, or when validate_arxiv_request or load_arxiv_paper would be more appropriate. The presence of validate_arxiv_request as a sibling makes this omission particularly problematic.

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