D1.9/5.0
Behavior2/5

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds nothing beyond them: it does not say what the required body must contain, whether the report is created empty or from a spec, or what side effects occur.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The sentence is short but is under-specification rather than conciseness — one tautological phrase that carries no informational weight. There is no front-loaded detail to trim because none exists.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be described. However, this open-world mutation tool has an entirely opaque required nested body object and no indication of what constitutes a valid report spec, making the definition inadequate for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The single required parameter `body` is a free-form object with additionalProperties=true and 0% schema description coverage. The description provides no field names, structure, or format guidance, leaving the agent with no way to construct a valid payload.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

"Create a report" merely restates the tool name (workbooks_create_report) and title with no added specificity. It does not distinguish this tool from close siblings such as workbooks_duplicate_report, workbooks_convert_workbook_to_report, or workbooks_create_report_schedule, which an agent could easily confuse it with.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use, prerequisite, or alternative guidance is given. The agent gets no signal about which sibling to choose when the user wants a new report versus a duplicated or converted one, nor any note about the payload needed.

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