plot_polar_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. It does not disclose any behavioral traits such as data requirements, handling of missing values, or side effects. The return value is only described as 'dict' with no further detail.

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 relatively short but includes a parameter list that duplicates the schema without adding value. The writing is sloppy with copy-paste errors. Every sentence should earn its place; here, the parameter descriptions are redundant and misleading.

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 presence of multiple sibling chart tools, the description fails to clarify what a polar chart is or when it should be used. With no output schema, the return value 'dict' is insufficient. The tool is incomplete for an agent to use correctly.

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?

Although schema coverage is 100%, the parameter descriptions merely repeat the schema text and contain errors (e.g., 'donut plot' for table_name, 'line plot' for others). They add no meaningful semantics beyond the schema, and the inconsistencies confuse the agent.

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 states it generates a polar area plot but includes contradictory references to 'donut plot' and 'line plot' in parameter descriptions. The phrase 'Columns mentioned in labels are used as labels' is unclear and lacks specificity. The verb 'generate' and resource 'polar area plot' are present but muddled by inconsistencies.

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 is provided on when to use this tool vs. sibling chart tools like plot_line_chart or plot_pie_chart. The description does not mention any selection criteria, prerequisites, or exclusions.

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