insert_pie_chart

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

No annotations provided. Description only mentions 'native pie chart' with fixed size, but fails to disclose behavioral traits like whether it overwrites existing content, placement behavior, or what happens with invalid data. Minimal beyond the schema.

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?

Extremely concise, two sentences with no filler. Front-loaded with purpose and format, making it efficient for quick comprehension.

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?

Despite having an output schema, the description does not mention return values or side effects. It leaves critical parameters like para_id and categories unexplained. For a tool with 4 required parameters and no annotations, the description is insufficiently complete.

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 0%. The description clarifies the series parameter format ('[{"name": str, "values": [float, ...]}]'), which adds value beyond the schema's vague 'array of objects'. However, the other three parameters (title, para_id, categories) are left unexplained, relying on their names.

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?

States verb 'Insert' and resource 'native pie chart' with constraints (single series, fixed size). However, does not differentiate from sibling chart tools like insert_bar_chart or insert_line_chart, which also insert charts with similar descriptions.

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?

No guidance on when to use this tool vs alternatives. Does not mention any prerequisites, limitations, or when not to use it.

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