xlsx_workbook_views

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

Annotations already indicate readOnlyHint and idempotentHint. The description adds significant context by detailing exactly what data is returned (visibility, view state, zoom, active cell, frozen panes, etc.), which goes beyond the annotations and fully informs the agent of tool behavior.

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 well-structured with a clear front-loaded purpose, followed by details and usage guidance. Every sentence adds value, and there is no redundancy or filler. It is appropriately sized for the information provided.

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 output schema and low schema coverage, the description provides thorough information about what the tool returns, including specific fields and usage scenarios. It covers both behavior and context, making it complete for a read-only inspection tool.

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 should compensate by explaining parameters. While it implies file_b64 is the file and options.sheet may filter, it does not explicitly define their meaning or format. The description mentions 'per sheet' but lacks a direct mapping to parameters, making it only partially adequate.

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 tool surfaces the UI state of a local .xlsx file, listing per-sheet and workbook-level details. It explicitly distinguishes from sibling tools like xlsx_read for reading values, making the purpose unambiguous.

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 explicit 'USE WHEN' and 'DO NOT USE WHEN' sections, specifying scenarios like resuming editing or auditing hidden sheets, and directing to xlsx_read for value reading. This provides clear decision guidance.

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