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 explicitly says 'Use this when the user explicitly asks for static or publication figures.' This provides clear when-to-use guidance. However, it does not explicitly mention alternatives (e.g., plot_interactive_correlation_heatmap) or when not to use.

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

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

No annotations are provided, so the description must carry the full burden. It does not disclose whether the plot is saved to a file or returned, any side effects, required permissions, or output format. The phrase 'for papers/publications' hints at file output but is insufficient.

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 short sentence, which is concise and front-loaded with the key information. However, it could be slightly more structured (e.g., listing parameters) without adding unnecessary length.

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 tool has 4 required parameters, no annotations, and an output schema exists, the description lacks details about return behavior or output. It does not mention how the histogram is delivered (e.g., file save, return object) or any prerequisites (e.g., Matplotlib/Seaborn installed).

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%, and the description adds no parameter-level guidance. While parameters like 'data_file_path' and 'column' are common, the tool would benefit from format hints or example values, especially for data_file_path.

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 tool generates a static histogram using Matplotlib/Seaborn for papers/publications. This distinguishes it from interactive histogram tools like plot_interactive_histogram and other static plot tools (e.g., plot_static_barchart).

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 implies usage for publication-quality static output but does not explicitly state when to prefer this over alternatives like interactive histograms or other static plots. No direct comparison or exclusion criteria are provided.

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

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

No annotations are provided, so the description carries full burden. It fails to disclose critical behavioral details such as output format (saved file vs. display), data constraints, error handling, or side effects, leaving the agent underinformed.

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 single-sentence description is concise and front-loaded, efficiently stating the core purpose. However, it could include additional useful information without becoming verbose.

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 and sibling tools, the description lacks completeness. It does not address the many parameters, expected data format, or behavior, which is insufficient for a tool with 7 parameters and no schema descriptions.

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, the description must compensate but provides no parameter explanations. Although parameter names like x_column and y_column are somewhat self-explanatory, the description adds no value beyond the schema, and parameters like data_file_path or hue_column remain unclarified.

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?

Description clearly states it generates a static Matplotlib/Seaborn line plot for papers/publications, distinguishing it from interactive siblings by specifying 'static' and the publication context.

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 implies use for static publication plots but does not explicitly state when to avoid this tool (e.g., for exploration) or mention alternatives like interactive line plots, though the context of 'papers/publications' provides some guidance.

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

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

No annotations are provided, so the description must disclose behavioral traits. It does not mention whether the plot is displayed or saved, how errors are handled for invalid columns, or any side effects. Minimal disclosure.

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?

Three sentences, concise and front-loaded. First sentence states purpose, second gives usage, third details parameters. No unnecessary words but could be better structured with explicit parameter descriptions.

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 4 parameters and no annotations, the description omits key details: what the output is (display/saved), prerequisites (file format), and error behavior. Lacks completeness for effective tool selection.

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 explains columns (comma-separated list) and hue_column (optional categorical), but fails to describe the required data_file_path parameter. Partial improvement over bare schema.

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?

Description clearly states 'Generates a Seaborn pair plot' with a specific verb and resource. It distinguishes from sibling tools like plot_interactive_scatter_matrix by noting it's a static pair plot for multi-feature exploration.

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?

Provides a usage context ('Use this for multi-feature distribution and correlation exploration') but does not specify when not to use this tool or mention alternatives like interactive versions.

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

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

With no annotations provided, the description carries the full burden; it mentions Matplotlib/Seaborn but fails to disclose output format, side effects, or constraints (e.g., file size, column requirements), leaving significant behavioral gaps.

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, concise sentence with no extraneous words, achieving maximal efficiency.

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 is too brief for a tool with 7 parameters; it omits prerequisites (e.g., data file format), the role of hue_column, and what the return value is, leaving the agent underinformed.

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%, yet the description provides no explanation of any of the 7 parameters (e.g., data_file_path, x_column, hue_column), offering zero added value beyond the schema field 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?

The description clearly states the action ('generates'), the resource ('static scatter plot'), and the context ('for papers/publications'), which distinguishes it from interactive plotting tools and other static plot types among siblings.

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 explicit guidance on when to use this tool versus alternatives such as interactive scatter plots or other static plot types; the description only implies usage for publication-quality plots without exclusions.

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

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

No annotations are provided, so the description must disclose behavioral traits. It only states the tool generates an image, but doesn't mention processing details (e.g., automatic text cleaning, handling of missing data, output format, or performance considerations). The description is too minimal for full transparency.

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 extremely concise: two sentences plus a parameter definition. It front-loads the purpose and usage, with no wasted words. Every sentence serves a clear function.

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 4 parameters, no schema descriptions, and no annotations, the description is insufficient. It fails to describe key parameters (data_file_path, text_column, title) and does not mention the output format (e.g., saved file, displayed image). The output schema exists but isn't referenced. The tool's behavior in edge cases (e.g., empty column) is not addressed.

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 explain each parameter's purpose. Only extra_stopwords is described (comma-separated words to exclude). The other three parameters (data_file_path, text_column, title) are not explained, leaving them ambiguous. This is a significant gap.

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 generates a static word cloud from a text column. It distinguishes from sibling plotting tools like bar charts or histograms, as word clouds are unique for visualizing frequent terms.

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?

Tells when to use: 'when the user wants to visualize the most frequent terms in a dataset.' Provides a specific hint for extra_stopwords. Does not explicitly list exclusions or alternatives, but among siblings, this is the only word cloud tool, so usage context is clear.

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

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 states that it calculates correlations for numeric columns, but does not disclose handling of missing values, data type requirements, or the fact that the method parameter defaults to 'pearson'. With an output schema present, return format is covered, but behavioral details are sparse.

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?

Two sentences with no filler. The first sentence states the core action and scope, the second gives the intended use case. Information is front-loaded and every sentence earns its place.

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 tool has 3 parameters (none described), no annotations, and an output schema, the description is incomplete. It fails to explain the parameters, the method options, or error conditions like non-numeric target columns. The use case is clear, but critical operational details are missing.

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%, meaning the input schema provides no parameter descriptions. The description does not mention any of the three parameters (data_file_path, target_col, method), leaving the agent to infer their roles. This is a significant gap.

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?

Description clearly states the verb (calculates and ranks) and resource (correlation between target column and all other numeric columns). It differentiates by saying 'at once' and provides an example use case (find top features related to diagnosis), which helps distinguish from siblings like run_correlation.

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?

Description explicitly says 'Use this tool when the user wants to rank, sort, or find top features related to a specific outcome column.' This provides clear context for when to use it, though it lacks explicit 'when not to use' or alternative tools.

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

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

With no annotations, the description carries the full burden of behavioral disclosure. It mentions computing correlation and available methods, but omits critical details like file read operations, handling of missing data, numeric type requirements, or any side effects. The output schema exists, so return value structure is covered, but behavioral traits are insufficiently described.

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 consists of two concise sentences. Each sentence serves a purpose: the first defines the tool's function, and the second provides usage guidance. No unnecessary words or redundancy.

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 tool's moderate complexity (4 parameters, file reading), the description is minimally adequate. It covers the core function and use case, but lacks details on parameter semantics, file requirements, and potential errors. The presence of an output schema mitigates the need for return value descriptions, but overall completeness is average.

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%, and the description adds no meaning to the parameters. It does not explain that 'data_file_path' refers to the file containing the columns, nor does it describe the 'method' parameter options or default. The schema itself provides basic info, but the description fails to compensate for the lack of schema descriptions.

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 tool computes statistical correlation (pearson, spearman) between two numeric columns. The verb 'computes' and resource 'statistical correlation' are specific, and it distinguishes from sibling plotting tools by emphasizing mathematical verification.

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 advises using this tool to mathematically verify relationships before plotting scatterplots, providing a clear context. However, it does not explicitly mention when not to use it or differentiate from sibling tools like 'rank_target_correlations' or correlation heatmaps, which might lead to ambiguity.

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

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

No annotations provided, so description carries full burden. It fails to disclose output format, side effects, assumptions, or whether data is modified, leaving agent uninformed about key behaviors.

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?

Two concise sentences with clear front-loading of what the tool does followed by usage advice, no wasted 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?

Despite having an output schema (not shown), the description lacks behavioral details and explanation of data_file_path, making it somewhat incomplete for a 3-param tool with no annotations.

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 coverage is 0%, description adds meaning to target_col and group_col but leaves data_file_path completely unexplained, providing only partial parameter understanding.

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?

Clearly states it performs T-tests or ANOVA to compare numeric variable across categories, explicitly linking to boxplot generation and distinguishing from sibling plotting and correlation 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?

Explicitly advises use before boxplots, and explains T-test vs ANOVA based on group count, giving clear when-to-use context. Lacks explicit when-not-to-use or alternatives.

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

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

No annotations present, so description must disclose behavior. Only states it runs OLS regression but omits side effects, output format, error handling, or assumptions. Minimal transparency.

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: three sentences with clear purpose, parameter explanation, and critical warning. No wasted 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?

Output schema exists but not shown; return values may be documented there. Lacks prerequisites (file must exist, columns present, data types). Adequate but incomplete for a regression tool.

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?

Adds meaning for target_col and predictor_cols (dependent/independent variables, JSON format requirement). However, data_file_path is undescribed. With 0% schema coverage, description partially compensates but misses one key parameter.

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?

Clearly states 'Runs an OLS Linear Regression' and defines target_col as dependent variable and predictor_cols as independent variables. Distinct from sibling tools which are other analyses or plotting.

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 explicit when to use or alternatives. Only implicit from the regression description. Does not explain when not to use or compare to other analysis tools.

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

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

Given no annotations, the description carries the full burden. It discloses the headless Chromium engine, fixed viewport size (1440x900), PNG output, file path return, and dependency on playwright installation. While it does not cover error handling or full-page behavior, it provides adequate transparency for a simple screenshot tool.

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 extremely concise: four sentences covering action, return, use case, parameter detail, and setup. Every sentence adds value and is front-loaded with the primary action.

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 simple screenshot tool, the description covers the essential aspects: input (url), output (file path), and purpose. It lacks details on timing or error conditions but is complete enough given the presence of an output schema and straightforward nature of the tool.

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 coverage is 0%, so the description compensates well. It explains the save_path parameter as 'optional absolute path for the PNG; auto-generated if omitted', adding meaning beyond the schema. The url parameter is self-explanatory and needs no further elaboration.

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 'Take a 1440x900 screenshot', resource 'webpage', format 'PNG', and the return value 'file path'. It also distinguishes from sibling tools like fetch_webpage and search_web by emphasizing visual inspection for design cloning.

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 a clear use case: 'visually inspecting a site's appearance and layout before cloning its design.' While it does not explicitly state when not to use or compare to alternatives, the context is well-defined and sufficient for an agent to decide when to invoke this tool.

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

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

No annotations provided, so description carries burden. States 'No API key required' (useful). Does not mention rate limits, error handling, or result structure beyond snippets. Adequate but minimal.

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?

Three sentences: purpose, usage, parameter. Front-loaded, no wasted words. Efficient and clear.

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?

Low complexity (2 params, simple). Output schema exists, so return values need not be explained. Description covers purpose, usage, and parameter details sufficiently.

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 description must compensate. Clearly explains max_results range (1-10, default 5) and implies query. Adds value beyond schema types.

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?

Clear verb ('search'), resource ('the internet using DuckDuckGo'), and output ('titles, URLs, and text snippets'). Distinguishes from siblings like fetch_webpage (single page) and find_in_files (local search).

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?
