plot_pairplot

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

With no annotations, the description carries the full burden. It discloses that computation is expensive and that the plot is limited to 6 columns, which is useful. However, it does not explain behavior for exceeding 6 columns, how df_name or save_path affect execution, or what the function returns (e.g., a plot object or file).

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 compact and front-loaded: the first sentence states what it does, followed by usage tips and an example. Every sentence adds value and it does not waste words.

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?

Although no output schema exists and annotations are absent, the description omits key contextual details such as how to specify the dataframe (df_name), how saving works (save_path), and what happens when more than 6 columns are passed. These are significant gaps for a plotting tool with 4 parameters.

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%, so the description must compensate. It provides an example using columns and hue, giving some meaning to those parameters. But it does not explain df_name or save_path at all, leaving half the parameters undocumented in both schema and description.

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 it creates a Seaborn pairplot for up to 6 columns, showing distributions on the diagonal and scatter plots off-diagonal. This specific verb+resource pairing and visual detail distinguish it from other plotting tools like plot_scatter or plot_histogram.

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 gives clear usage context: 'Use after feature_importance to focus on top features' and advises limiting to 6 columns for readability. It also warns that computation is expensive. However, it does not explicitly state when not to use it or mention alternatives beyond the implicit comparison.

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