excel_inspect

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

No annotations are present, so the description carries the burden of behavioral disclosure. The verb 'inspect' implies a read-only operation, but the description does not explicitly state that the workbook is never modified, nor does it explain behavior for invalid paths or access requirements. It conveys the core intent without exposing edge 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 a single efficient sentence with the action and resource front-loaded and no filler words. It is concise, though it misses the opportunity to add routing or constraint context that would make it more informative.

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 is simple, has only two parameters with full schema coverage, and an output schema exists, so the short description is nearly sufficient. However, it leaves 'structural metadata' slightly underspecified and provides no guidance on choosing this over excel_read_range, which are meaningful completeness gaps.

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%, so the baseline is 3 even without additional parameter detail. The description adds no meaning beyond 'workbook' and 'structural metadata,' but the schema already sufficiently documents path and the optional sheet_name.

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 names a specific verb, 'inspect,' and a specific resource, 'Excel workbook,' with the scope 'structural metadata,' which distinguishes it from sibling tools like excel_read_range (cell data) and excel_open. It does not enumerate what metadata is returned, so it is clear but not maximally precise.

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?

There is no explicit when-to-use or when-not-to-use guidance, and no alternative is named. The phrase 'structural metadata' implies using this tool when workbook structure is needed, but the agent is left to infer the distinction from sibling names rather than from stated instructions.

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