excel_to_csv

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

With no annotations provided, the description carries the full burden of behavioral disclosure. However, it only states the basic conversion fact and does not disclose that this is an API-based operation requiring authentication (as hinted by the api_key parameter), potential rate limits, side effects, or handling of temporary files. The reference link is not part of the behavioral description and provides no in-tool transparency.

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 unnecessary words, front-loading the core function. It also includes a reference link for further documentation, adding value without bloat. Perfectly concise and well-structured for its length.

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?

The tool has six parameters, no output schema, and no annotations, yet the description only states the basic conversion. It omits mention of authentication, worksheet selection, when to use the http username/password parameters, or the fact that a URL must be accessible. This is insufficient for a tool of this complexity; a minimal viable description would at least hint at these operational aspects.

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%, so all six parameters already have descriptive titles and descriptions in the schema. The description adds no additional parameter semantics, which aligns with the baseline score of 3 for high schema coverage. It does not introduce new meaning or clarify usage edge cases beyond what the schema provides.

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 'Convert Excel(XLS, XLSX) to CSV' clearly states the action, input format, and output format. It distinguishes this tool from sibling tools like excel_to_json and excel_to_pdf by explicitly naming CSV as the target format, leaving no ambiguity about its purpose.

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 does not mention conditions, prerequisites, or exclusions, and offers no comparison with sibling tools such as excel_to_xml or excel_to_html. The agent is left to infer usage solely from the name.

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