excel_create_dashboard_chart

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

With no annotations provided, the description carries full burden for behavioral disclosure. While 'create' implies a write operation, the description doesn't specify whether this creates a new file or modifies an existing one, what permissions are required, whether it overwrites existing content, or what happens on failure. It mentions 'comprehensive data visualization' but doesn't explain what that entails behaviorally.

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 gets straight to the point. It uses minimal words to convey the core functionality without any fluff or unnecessary elaboration. Every word serves a purpose in defining what the tool does.

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?

For a tool with 3 parameters (including a complex nested object), 67% schema coverage, no annotations, and no output schema, the description is insufficient. It doesn't address the tool's behavior, error conditions, output format, or how it differs from similar chart creation tools in the extensive sibling list. The description leaves too many questions unanswered for proper agent usage.

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 description mentions 'multi-series dashboard chart' which aligns with the primaryChart parameter containing series data, but adds no specific parameter semantics beyond what the 67% schema coverage provides. The schema already documents fileName, dashboardTitle, and primaryChart structure with types, categories, and series. The description doesn't explain parameter relationships or provide usage examples.

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 verb 'create' and the resource 'multi-series dashboard chart' with the purpose of 'comprehensive data visualization'. It distinguishes from simpler chart tools like 'excel_create_native_chart' by specifying 'dashboard' and 'multi-series', but doesn't explicitly differentiate from similar siblings like 'excel_create_business_chart' or 'excel_create_financial_chart'.

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. With many sibling tools including various chart creation tools (excel_create_business_chart, excel_create_financial_chart, excel_create_smart_chart), there's no indication of what makes this dashboard chart tool different or when it's preferred over other visualization options.

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