configure_chart

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

The description provides zero behavioral information beyond the basic purpose. With no annotations provided, the description carries full burden but fails to disclose whether this is a read or write operation, what permissions are required, whether changes are destructive, what happens to existing chart configurations, or any error conditions. This is completely inadequate for a tool with 23 parameters.

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 zero wasted words. It's appropriately sized and front-loaded with the essential information about 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 complex configuration tool with 23 parameters, no annotations, and 0% schema description coverage, the description is completely inadequate. While an output schema exists, the description provides no context about the tool's behavior, parameter usage, or relationship to sibling tools. This leaves the agent with insufficient information to use the tool effectively.

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?

With 0% schema description coverage and 23 parameters, the description provides no information about any parameters. It doesn't explain what 'mark_type' means, what 'columns' and 'rows' represent, how 'color_map' works, or any other parameter semantics. The description fails completely to compensate for the schema's lack of 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 action ('configure') and target ('chart type and field mappings for a worksheet'), providing a specific verb+resource combination. However, it doesn't distinguish this tool from sibling tools like 'configure_chart_recipe' or 'configure_dual_axis', which appear to be related chart configuration tools.

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 multiple configuration-related siblings (configure_chart_recipe, configure_dual_axis, configure_worksheet_style), there's no indication of when this specific chart configuration tool is appropriate versus those other options.

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