excel_create_business_chart

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 tool creates charts with 'intelligent defaults,' but does not clarify if this is a read-only or write operation, what permissions are needed, how errors are handled, or the output format. For a tool with no annotations, this is a significant gap in transparency.

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 that is front-loaded with the core purpose. It avoids redundancy and wastes no words, making it highly concise and well-structured for quick understanding.

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 tool's complexity (4 parameters, nested objects, no output schema, and no annotations), the description is insufficient. It lacks details on behavioral traits, output format, error handling, and how it differs from sibling tools. The high schema coverage helps, but the description does not compensate for the missing contextual information needed for effective tool use.

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 75%, providing good documentation for most parameters. The description adds minimal value beyond the schema, mentioning 'business scenarios' and 'intelligent defaults,' which loosely relate to the 'businessScenario' parameter and implied defaults, but does not elaborate on parameter meanings or usage. With high schema coverage, the baseline score of 3 is appropriate.

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 purpose: 'Create charts optimized for specific business scenarios with intelligent defaults.' It specifies the verb ('Create'), resource ('charts'), and key differentiator ('optimized for specific business scenarios'), but does not explicitly distinguish it from sibling tools like 'excel_create_financial_chart' or 'excel_create_dashboard_chart' beyond the 'business scenarios' focus.

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 mentions 'business scenarios' but does not specify prerequisites, exclusions, or compare it to sibling tools such as 'excel_create_financial_chart' or 'excel_create_smart_chart', leaving the agent to infer usage context.

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