xlsx-to-markdown

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 states the conversion action but doesn't mention critical details like whether the tool modifies the original file, requires specific permissions, handles errors (e.g., invalid file formats), or outputs to a specific location. For a file-processing tool with zero annotation coverage, this is a significant gap.

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, clear sentence with zero wasted words. It's front-loaded with the core action and resource, making it highly efficient and easy to parse, which is ideal for quick tool selection by an AI agent.

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 the lack of annotations and output schema, the description is incomplete for a file conversion tool. It doesn't explain what the markdown output looks like (e.g., table formatting for spreadsheets), error handling, or dependencies, leaving the agent with insufficient context for reliable invocation despite the simple parameter schema.

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 100%, with the single parameter 'filepath' well-documented in the schema as 'Absolute path of the XLSX file to convert'. The description adds no additional parameter semantics beyond what the schema provides, so it meets the baseline score of 3 for high schema coverage without extra value.

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 'convert' and the resource 'XLSX file to markdown', making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'docx-to-markdown' or 'pdf-to-markdown' beyond specifying the input format, missing an opportunity to highlight unique aspects of XLSX conversion.

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. With multiple '*-to-markdown' siblings available, it doesn't specify scenarios where XLSX conversion is appropriate (e.g., for spreadsheet data) or when other tools might be better suited, leaving the agent to infer usage from the name alone.

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