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

The annotations already declare readOnlyHint=true, so the read-only nature is established. The description adds the inventory content but does not disclose other behaviors like result format, performance impact, or error conditions. This adds some value but not substantial context beyond annotations.

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 concise sentence with no redundancy or extraneous detail. It is front-loaded with the main action and resource, making it easy to parse.

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 description outlines the inventory content but leaves out details on the structure or format of the returned data, and does not clarify terms like 'layout state.' With no output schema and a single obvious parameter, the description is minimally adequate but not fully complete for an agent to predict the tool's exact output.

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?

The schema has no description for the 'filepath' parameter (0% coverage). The tool description does not explain the expected path format, file types, or any constraints. Although the parameter name is self-explanatory, the description fails to compensate for the lack of schema-level documentation.

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's action ('Return') and resource ('a compact workbook inventory'), specifying the contents as sheets, tables, charts, and layout state. This distinguishes it from sibling tools like list_all_sheets or list_charts, which focus on individual aspects.

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 scenarios such as needing a quick overview or avoiding multiple list calls, leaving the agent without cues for tool selection.

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