Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v1.0.0
Disambiguation3/5
The tools cover distinct Excel/data analysis functions, but there is significant overlap in some areas. For example, 'read_file' and 'read_file_chunked' serve similar purposes with minor differences, and 'bulk_aggregate_multi_files' and 'aggregate' could be confused for related operations. Descriptions help clarify, but the high count increases potential for misselection.
Naming Consistency3/5
Naming conventions are mixed, with some tools using verb_noun patterns (e.g., 'add_sheet', 'filter_rows') and others using noun_verb or descriptive phrases (e.g., 'data_cleaner', 'dcf_analysis'). While readable, the lack of a uniform pattern across all 35 tools reduces predictability and consistency.
Tool Count2/5
With 35 tools, the server feels overloaded for an Excel-focused domain. Many tools could be consolidated or parameterized (e.g., 'read_file' and 'read_file_chunked'), leading to a heavy and potentially confusing interface. This exceeds the typical well-scoped range of 3-15 tools, indicating poor scoping.
Completeness4/5
The tool set provides extensive coverage for Excel operations, including data I/O, analysis, formatting, and advanced functions like AI integration and financial modeling. Minor gaps exist, such as limited editing capabilities for existing files, but agents can work around these given the broad functionality available.
Average 2.9/5 across 35 of 35 tools scored.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions 'what-if scenario analysis' which implies read-only or computational behavior, but fails to specify if it modifies data, requires specific permissions, handles errors, or outputs results. This leaves significant gaps for a tool that processes files and scenarios.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that states the core function without unnecessary details. It is appropriately sized for the tool's complexity, though it could be more front-loaded with specific resource information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of a scenario analysis tool with no annotations and no output schema, the description is incomplete. It does not explain what the tool returns (e.g., results, reports, errors) or how it interacts with the data, leaving the agent uncertain about behavioral outcomes and usage context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the input schema fully documents parameters like 'filePath', 'sheet', and 'scenarios'. The description adds no additional meaning beyond what's in the schema, such as explaining the structure of 'scenarios' or file formats. Baseline 3 is appropriate as the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Perform what-if scenario analysis with multiple assumptions' states the general purpose but lacks specificity about what resource it operates on (e.g., financial models, datasets) or how it differs from similar tools like 'budget_variance_analysis' or 'dcf_analysis'. It's vague about the exact nature of the analysis.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 versus alternatives such as 'budget_variance_analysis' or 'dcf_analysis', which might also involve scenario modeling. The description does not mention prerequisites, exclusions, or specific contexts for application.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions 'AI-powered analysis suggestions' but doesn't explain what this entails—such as whether it performs data processing, requires specific permissions, has rate limits, or what the output looks like. For a tool with no annotation coverage, this is a significant gap in transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence: 'AI-powered analysis suggestions for your data'. It is front-loaded and wastes no words, making it appropriately concise. However, it could be more structured by including key details upfront, but it earns high marks for brevity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of AI-powered analysis, no annotations, and no output schema, the description is incomplete. It doesn't explain what 'analysis suggestions' entail, the format of results, or any behavioral traits like error handling. For a tool with 3 parameters and rich sibling context, this leaves significant gaps in understanding its full functionality.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description coverage is 100%, meaning all parameters are documented in the input schema. The description adds no additional meaning beyond the schema, such as explaining how 'filePath' relates to data analysis or the implications of choosing different 'provider' options. With high schema coverage, the baseline score of 3 is appropriate as the description doesn't compensate but also doesn't detract.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states the tool provides 'AI-powered analysis suggestions for your data', which indicates its general purpose but lacks specificity. It mentions 'analysis suggestions' rather than a concrete action like 'generate insights' or 'identify patterns', and doesn't distinguish from siblings like 'statistical_analysis' or 'correlation_analysis' that might offer similar analytical functions. This makes the purpose somewhat vague.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 many sibling tools like 'statistical_analysis', 'correlation_analysis', and 'data_profile' that might overlap in analytical capabilities, there is no indication of context, prerequisites, or exclusions. This leaves the agent without clear usage instructions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions 'comprehensive statistical analysis' but doesn't specify what analyses are performed, output format, error handling, or performance considerations. This leaves critical behavioral traits undefined for a tool with potential complexity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that directly states the tool's function without unnecessary words. It's appropriately sized for its purpose, though it could be more front-loaded with key details given the lack of other guidance.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's potential complexity (statistical analysis), no annotations, no output schema, and many sibling tools, the description is incomplete. It fails to explain what 'comprehensive' means, output expectations, or how it differs from other analysis tools, leaving significant gaps for effective use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents the three parameters (filePath, column, sheet). The description adds no additional meaning beyond the schema, such as examples or constraints, but the high coverage justifies a baseline score of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states the tool 'perform[s] comprehensive statistical analysis on a column,' which provides a clear verb ('perform') and resource ('column'), but it's vague about what 'comprehensive statistical analysis' entails. It doesn't differentiate from siblings like 'data_profile,' 'correlation_analysis,' or 'trend_analysis,' leaving ambiguity in its specific purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 versus alternatives. With many sibling tools for data analysis (e.g., 'correlation_analysis,' 'trend_analysis,' 'data_profile'), the description lacks context on its unique application, prerequisites, or exclusions, offering no help in tool selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but only states the operation without behavioral details. It doesn't disclose what the tool returns (e.g., a numeric result), error handling, performance implications, or side effects (e.g., file reading). This is inadequate for a tool with 4 parameters and no output schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with zero waste. It's front-loaded and appropriately sized for the tool's complexity, though it could benefit from more detail given the lack of annotations and output schema.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 4 parameters, no annotations, and no output schema, the description is incomplete. It doesn't explain the return value (e.g., a numeric aggregate), file format support beyond what's in the schema, or how it differs from sibling tools. This leaves significant gaps for an AI agent to use it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents parameters like 'filePath' and 'operation' with enum values. The description adds no meaning beyond the schema, merely restating 'aggregation operations on a column'. Baseline 3 is appropriate as the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Perform aggregation operations on a column' states the basic action but is vague about the context (data files) and doesn't distinguish from siblings like 'bulk_aggregate_multi_files' or 'statistical_analysis'. It specifies the target ('a column') but lacks detail on the resource (CSV/Excel files mentioned only in schema).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 versus alternatives like 'bulk_aggregate_multi_files' for multiple files or 'statistical_analysis' for broader operations. The description implies usage for column aggregation but offers no context, exclusions, or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It states 'Add a new sheet' which implies a write/mutation operation, but doesn't disclose critical traits like whether it modifies the original file in-place, requires write permissions, handles errors (e.g., duplicate sheet names), or what happens if the file doesn't exist. This leaves significant gaps for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
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 for the tool's complexity and front-loads the core purpose immediately.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a mutation tool with no annotations and no output schema, the description is insufficiently complete. It doesn't explain what the tool returns (success/failure indicators, sheet reference), doesn't cover error conditions or constraints, and provides minimal behavioral context. The 100% schema coverage helps with parameters but doesn't compensate for the overall context gap.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all 5 parameters. The description adds no additional parameter semantics beyond what's in the schema - it doesn't explain relationships between parameters (e.g., how 'data' interacts with 'headers') or provide usage examples. Baseline 3 is appropriate when schema does all the work.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Add a new sheet') and target resource ('to an existing Excel file'), providing a specific verb+resource combination. However, it doesn't differentiate from sibling tools like 'write_multi_sheet' or 'write_file' that might also modify Excel files, so it doesn't fully distinguish from alternatives.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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. It doesn't mention prerequisites (e.g., file must exist), exclusions, or compare with sibling tools like 'write_multi_sheet' for multi-sheet creation or 'write_file' for file-level operations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions 'analyze' and 'variance calculations,' implying a read-only computation, but doesn't specify if it modifies files, requires specific permissions, handles errors, or outputs results in a particular format. For a tool with 4 parameters and no annotations, this leaves significant behavioral gaps, such as whether it's destructive or has rate limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence: 'Analyze budget vs actual performance with variance calculations.' It's front-loaded with the core purpose, has zero wasted words, and is appropriately sized for the tool's complexity. Every part of the sentence contributes directly to understanding the tool's function.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations, no output schema, and 4 parameters, the description is incomplete. It doesn't cover behavioral aspects like safety or performance, output format, or error handling. For a data analysis tool with multiple inputs, more context is needed to ensure the agent can use it correctly, such as what the variance calculations entail or how results are returned.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage, detailing each parameter (e.g., 'filePath' as path to CSV/Excel). The description adds no additional parameter semantics beyond the schema, as it doesn't explain how 'actualColumn' and 'budgetColumn' interact or provide examples. With high schema coverage, the baseline is 3, but the description doesn't compensate with extra insights, so it meets the minimum viable level.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Analyze budget vs actual performance with variance calculations.' It specifies the verb ('analyze'), resource ('budget vs actual performance'), and method ('variance calculations'), making it easy to understand what the tool does. However, it doesn't explicitly differentiate from sibling tools like 'ratio_analysis' or 'trend_analysis,' which might also involve financial comparisons, so it misses full sibling differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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. It doesn't mention prerequisites (e.g., needing a data file), exclusions, or comparisons to siblings like 'correlation_analysis' or 'statistical_analysis' that might handle similar data. Without any context on usage scenarios or alternatives, the agent lacks direction for selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It mentions 'optional export' but doesn't explain what happens during filtering (e.g., whether original files are modified, what format the export takes, performance implications for multiple files, or error handling). For a tool with 5 parameters and no annotation coverage, this is inadequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that states the core functionality. It's appropriately sized and front-loaded with the main purpose. However, it could be slightly more informative given the tool's complexity without becoming verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 5 parameters, no annotations, and no output schema, the description is insufficient. It doesn't explain what the tool returns (counts, exported files, or summaries), how errors are handled with multiple files, or performance considerations. The lack of output schema means the description should compensate by explaining return values, which it doesn't do.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents all parameters thoroughly. The description adds minimal value beyond the schema - it mentions 'optional export' which relates to the outputMode parameter, but doesn't provide additional context about parameter interactions or usage patterns. Baseline 3 is appropriate when the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Filter data across multiple files with optional export'. It specifies the verb ('filter'), resource ('data across multiple files'), and optional capability ('export'). However, it doesn't explicitly differentiate from sibling tools like 'filter_rows' or 'bulk_aggregate_multi_files', which prevents a perfect score.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 sibling tools like 'filter_rows' (single file) and 'bulk_aggregate_multi_files' (different operation), there's no indication of when this multi-file filtering tool is preferred or what distinguishes it from similar tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. It states what the tool does but doesn't mention critical behaviors like what correlation method is used (e.g., Pearson), error handling for non-numeric data, performance characteristics, or output format. For a statistical tool with zero annotation coverage, this leaves significant gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with zero wasted words. It's front-loaded with the core purpose and appropriately sized for a straightforward tool, making it easy for an agent to parse quickly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of statistical analysis, lack of annotations, and no output schema, the description is incomplete. It doesn't explain what the tool returns (e.g., correlation coefficient, p-value), error conditions, or behavioral nuances. For a tool with 4 parameters and no structured output definition, more context is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all parameters. The description doesn't add any semantic context beyond what's in the schema (e.g., explaining how column names/indices work together, file format limitations, or the optional 'sheet' parameter's role). Baseline 3 is appropriate when the schema does all the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Calculate correlation') and the target ('between two numeric columns'), providing a specific verb+resource combination. However, it doesn't differentiate from sibling tools like 'statistical_analysis' or 'smart_data_analysis' that might offer similar functionality, preventing a perfect score.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 sibling tools that might perform statistical operations (e.g., 'statistical_analysis', 'trend_analysis'), there's no indication of when this specific correlation calculation is preferred or what prerequisites exist (e.g., numeric data requirements).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It mentions 'intelligent detection' but doesn't explain what this entails operationally—whether it modifies files in-place, creates backups, has performance characteristics, or requires specific permissions. For a batch processing tool with mutation implications, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that immediately communicates the core functionality without unnecessary words. It's appropriately sized and front-loaded with the essential information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a data cleaning tool with 4 parameters, no annotations, and no output schema, the description is insufficient. It doesn't address critical behavioral aspects like whether changes are destructive, what formats are supported beyond CSV/Excel, error handling, or output expectations. The context signals indicate this is a moderately complex tool that needs more complete documentation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents all four parameters thoroughly. The description adds no additional meaning about parameters beyond what's in the schema—it doesn't explain how operations interact, what 'intelligent detection' means for parameter selection, or provide usage examples.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool performs 'Batch data cleaning operations' with 'intelligent detection of common data quality issues', specifying both the verb (cleaning) and resource (data). However, it doesn't explicitly differentiate from siblings like 'validate_data_consistency' or 'find_duplicates' which might overlap in data quality domains.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 versus alternatives. With siblings like 'validate_data_consistency', 'find_duplicates', and 'smart_data_analysis' that might handle similar data quality tasks, the description offers no context about appropriate use cases or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. While 'generate comprehensive data profiling report' implies a read-only analysis operation, the description doesn't specify what 'comprehensive' includes, whether it modifies the source file, what format the report takes, or any performance considerations. For a tool with no annotation coverage, this leaves significant behavioral questions unanswered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise - a single sentence that efficiently communicates the core function. Every word earns its place: 'Generate' (action), 'comprehensive data profiling report' (output), 'for all columns' (scope). There's no wasted verbiage or unnecessary elaboration.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of data profiling (which typically includes statistics, data types, null counts, patterns, etc.), the lack of annotations, and no output schema, the description is insufficient. It doesn't explain what 'comprehensive' means, what the report format is, or how results are returned. For a tool that presumably produces rich analytical output, more context is needed about what the agent can expect.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already fully documents both parameters (filePath and sheet). The description doesn't add any parameter-specific information beyond what's in the schema. According to scoring rules, when schema_description_coverage is high (>80%), the baseline is 3 even with no param info in the description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Generate comprehensive data profiling report for all columns.' It specifies the action (generate), the output type (data profiling report), and scope (for all columns). However, it doesn't differentiate from sibling tools like 'statistical_analysis' or 'smart_data_analysis' that might also analyze data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 many sibling tools for data analysis (statistical_analysis, correlation_analysis, trend_analysis, etc.), there's no indication of what distinguishes data profiling from these other analytical functions or when it's the appropriate choice.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool performs DCF analysis but doesn't describe what the tool actually does behaviorally: e.g., whether it modifies files, requires specific permissions, outputs results to a file or console, handles errors, or has performance constraints like rate limits. For a tool with no annotations and complex financial calculations, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that directly states the tool's purpose without redundancy. It's appropriately sized for a tool with a clear name and well-documented schema, and it's front-loaded with the core function. There's no wasted verbiage.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of DCF analysis (involving financial modeling), no annotations, and no output schema, the description is incomplete. It doesn't cover behavioral aspects like what the tool returns (e.g., a valuation figure, a report, or an error), how it processes the file, or any limitations. For a tool with nested parameters and no structured output documentation, more context is needed to guide the agent effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents all parameters thoroughly. The description doesn't add any semantic context beyond what's in the schema—it doesn't explain how parameters interact (e.g., how assumptions apply to the cash flow data) or provide usage examples. With high schema coverage, the baseline score of 3 is appropriate, as the description adds no extra parameter value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Perform Discounted Cash Flow (DCF) valuation analysis for investment evaluation.' It specifies the verb ('perform') and resource ('Discounted Cash Flow valuation analysis'), making the function unambiguous. However, it doesn't explicitly differentiate from sibling tools like 'budget_variance_analysis' or 'scenario_modeling' that might also involve financial analysis.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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. It doesn't mention prerequisites (e.g., needing cash flow data files), exclusions (e.g., not for real-time data), or comparisons to sibling tools like 'ratio_analysis' or 'trend_analysis'. The agent must infer usage from the tool name and parameters alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but provides minimal behavioral insight. It mentions evaluating with 'given context' but doesn't disclose error handling, performance limits, or what the evaluation entails (e.g., returns a value, modifies data). This is inadequate for a tool with potential computational complexity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with zero waste. It's front-loaded with the core purpose, making it easy to scan and understand quickly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations and no output schema, the description is incomplete. It doesn't explain what the tool returns (e.g., result value, error details) or behavioral aspects like side effects, making it insufficient for safe and effective use by an AI agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents parameters. The description adds no extra meaning beyond implying 'context' is for cell values, which is already in the schema. Baseline 3 is appropriate as the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('evaluate') and resource ('Excel formula'), specifying it's for evaluation with given context. It distinguishes from siblings like 'explain_formula' by focusing on execution rather than explanation, though it doesn't explicitly contrast with all siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives is provided. It doesn't mention when to choose this over 'explain_formula' or other formula-related tools, nor does it specify prerequisites or exclusions for usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool exports to a 'new file', implying a write operation, but does not cover critical aspects like file format, overwrite behavior, permissions needed, error handling, or rate limits. This is inadequate for a tool with no annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that front-loads the core action ('export analysis results') and includes helpful examples ('pivot tables, statistics, etc.'). There is no wasted wording, making it appropriately concise and well-structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations and no output schema, the description is incomplete for a tool with 4 parameters and nested objects. It lacks details on behavioral traits, output format, error conditions, and how it differs from sibling tools, making it insufficient for an agent to use effectively without additional context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents all parameters thoroughly. The description adds minimal value by implying the tool handles 'analysis results' but does not provide additional context or meaning beyond what the schema specifies, such as how 'analysisParams' relates to 'analysisType'. Baseline 3 is appropriate here.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'export' and the resource 'analysis results' with examples like 'pivot tables, statistics, etc.', making the purpose specific and understandable. However, it does not explicitly differentiate from sibling tools like 'write_file' or 'bulk_aggregate_multi_files', which might also involve file output, so it lacks sibling differentiation for a perfect score.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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, such as 'write_file' for general file writing or specific analysis tools like 'pivot_table'. There is no mention of prerequisites, context, or exclusions, leaving the agent with minimal usage direction.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool filters rows but doesn't mention whether this is a read-only operation, if it modifies the original file, what the output format is (e.g., returns filtered data or saves to a new file), or any performance considerations like handling large files. For a tool with 5 parameters and no annotations, this leaves 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with zero waste: 'Filter rows based on column values'. It's front-loaded with the core action and resource, making it immediately understandable without unnecessary elaboration. Every word earns its place by specifying the tool's purpose directly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (5 parameters, no annotations, no output schema), the description is incomplete. It doesn't explain the return values (e.g., whether filtered data is returned or saved), behavioral traits like file modification, or how it differs from sibling tools. For a data filtering tool with multiple parameters, this minimal description leaves too much unspecified for effective agent use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description coverage is 100%, with each parameter well-documented in the input schema (e.g., 'filePath' as path to CSV/Excel, 'condition' with enum values). The description adds no additional parameter semantics beyond what's in the schema, such as examples or edge cases. With high schema coverage, the baseline score of 3 is appropriate as the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Filter rows based on column values' clearly states the tool's function with a specific verb ('filter') and resource ('rows'), and it specifies the filtering mechanism ('based on column values'). However, it doesn't distinguish this tool from sibling tools like 'bulk_filter_multi_files' or 'search', which might offer similar filtering capabilities with different scopes or approaches.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 sibling tools like 'bulk_filter_multi_files' (for multiple files) and 'search' (which might offer broader search functionality), there's no indication of this tool's specific context, prerequisites, or exclusions. Usage is implied only by the tool name and description, lacking explicit when/when-not instructions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 mentions 'multiple strategies' but doesn't specify what they are, how duplicates are identified (e.g., exact matches, fuzzy logic), or the tool's behavior (e.g., whether it modifies files in-place, creates new files, or requires specific permissions). This leaves significant gaps for a tool that performs file operations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that front-loads the core purpose. It avoids unnecessary words, though it could be slightly more structured by explicitly listing the strategies or use cases to enhance clarity without sacrificing brevity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (file operations with multiple actions), lack of annotations, and no output schema, the description is incomplete. It doesn't cover behavioral aspects like file modification effects, error handling, or output format, which are critical for safe and effective tool invocation by an AI agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents all parameters thoroughly. The description adds no additional meaning beyond what's in the schema, such as explaining the 'multiple strategies' mentioned or providing examples. Baseline 3 is appropriate when the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb ('find and manage') and resource ('duplicate rows in Excel/CSV files'), distinguishing it from siblings like data_cleaner or validate_data_consistency. However, it doesn't explicitly differentiate from all possible alternatives, such as filter_rows or search, which could also handle duplicates in some contexts.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 many sibling tools like data_cleaner, filter_rows, and search, there's no indication of specific scenarios, prerequisites, or exclusions for choosing find_duplicates over other options.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but only states what the tool does, not how it behaves. It doesn't disclose that this is a mutation operation (modifies files), potential side effects (overwrites existing formatting), error conditions, or response format. For a tool that modifies Excel files, this is a significant gap in behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise single sentence with zero waste. Every word earns its place: 'Apply formatting' (action), 'to Excel cells' (target), and parenthetical examples of formatting types. No redundant information or unnecessary elaboration.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a mutation tool with no annotations and no output schema, the description is insufficient. It doesn't explain what happens after formatting is applied (success/failure indicators), whether changes are saved automatically, or any behavioral constraints. The 100% schema coverage helps with parameters, but overall context for a file-modifying operation is inadequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all 4 parameters and their nested properties. The description adds minimal value beyond the schema by listing formatting categories (fonts, colors, borders, alignment) which are already detailed in the schema. Baseline 3 is appropriate when schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb ('Apply formatting') and resource ('to Excel cells'), with specific formatting types listed (fonts, colors, borders, alignment). It distinguishes from siblings like 'write_file' or 'get_cell' by focusing on styling, but doesn't explicitly differentiate from all possible formatting-related tools that might exist.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided about when to use this tool versus alternatives. There's no mention of prerequisites (e.g., file must exist), when not to use it, or how it relates to sibling tools like 'write_file' (which might also handle formatting). The description assumes the user knows when formatting is needed.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool reads a cell value but doesn't mention file format support (CSV/Excel), error handling for invalid cells or files, performance considerations, or output format. For a read operation with zero annotation coverage, this leaves significant gaps in understanding how the tool behaves.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that directly states the tool's purpose without unnecessary words. It is front-loaded with the core action and uses specific terminology ('A1 notation') that adds precision without verbosity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations, no output schema, and a read operation with potential complexity (file formats, error cases), the description is incomplete. It doesn't address what happens with missing files, invalid cell references, or the return format, leaving the agent under-informed for reliable use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all parameters. The description adds minimal value beyond the schema by mentioning A1 notation, which is already implied in the schema's description for 'cell'. No additional semantics or usage examples are provided, meeting the baseline for high schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb ('Get') and resource ('value of a specific cell'), specifying the action and target. It distinguishes from siblings like 'get_range' by focusing on a single cell rather than a range, though it doesn't explicitly name alternatives. However, it lacks explicit sibling differentiation beyond the scope implied by 'specific cell'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 like 'get_range', 'read_file', or 'vlookup_helper'. It mentions A1 notation but doesn't specify use cases, prerequisites, or exclusions, leaving the agent to infer usage from the tool name and parameters alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions analysis and recommendations but lacks details on permissions, rate limits, response format, or whether this is a read-only operation. For a tool with no annotation coverage, this leaves significant gaps in understanding its behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise with just one sentence that efficiently conveys the core functionality. It's front-loaded with key actions ('analyze', 'get') and avoids any redundant or verbose language, making it easy to parse quickly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of file analysis and the lack of annotations and output schema, the description is incomplete. It doesn't explain what 'chunking recommendations' entail, the format of the analysis results, or how this tool differs from other file-related siblings, leaving the agent with insufficient context for effective use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents both parameters ('filePath' and 'sheet') adequately. The description doesn't add any parameter-specific details beyond what's in the schema, such as file format constraints or chunking criteria, resulting in a baseline score of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose with specific verbs ('analyze', 'get') and resources ('file size', 'chunking recommendations'), making it easy to understand what the tool does. However, it doesn't explicitly differentiate from sibling tools like 'read_file' or 'data_profile' that might also provide file information, preventing a perfect score.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 many sibling tools available (e.g., 'read_file', 'data_profile', 'get_headers'), there's no indication of specific contexts, prerequisites, or exclusions for using 'get_file_info', leaving the agent to guess based on tool names alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions 'Get values' but does not specify whether this is a read-only operation, what happens with invalid ranges, if it requires file permissions, or the format of returned data. This leaves significant gaps in understanding the tool's behavior and limitations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that directly states the tool's purpose without unnecessary words. It is front-loaded and wastes no space, making it easy to grasp quickly.

Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of annotations and output schema, the description is incomplete. It does not explain what the tool returns (e.g., data format, error handling) or behavioral aspects like performance or constraints. For a tool with 4 parameters and no structured output information, more context is needed to ensure proper usage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description does not add meaning beyond the input schema, which has 100% coverage with clear descriptions for all parameters. Since the schema fully documents the parameters, the baseline score of 3 is appropriate, as the description neither compensates for gaps nor enhances understanding of the parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Get values') and resource ('from a range of cells'), making the purpose understandable. However, it does not distinguish this tool from similar siblings like 'get_cell' or 'read_file', which might also retrieve data from files, leaving some ambiguity about its specific role.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 many sibling tools like 'get_cell', 'read_file', and 'filter_rows' that might overlap in functionality, there is no indication of context, prerequisites, or exclusions for using 'get_range'.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. While 'convert' implies a transformation operation, it doesn't specify whether this requires external API calls (given the provider parameter), what happens with the optional filePath context, rate limits, error conditions, or what the output format looks like (formula string, command object, etc.).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?

Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of natural language to formula conversion, no annotations, and no output schema, the description is inadequate. It doesn't explain what kind of output to expect (Excel formula syntax, command objects, error handling), nor does it address the implications of the provider parameter for AI service usage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, providing good documentation for all three parameters. The description adds no additional parameter semantics beyond what's already in the schema, so it meets the baseline of 3 where the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function as converting natural language to Excel formulas or commands, which is a specific verb+resource combination. However, it doesn't distinguish itself from sibling tools like 'evaluate_formula' or 'explain_formula' that also work with formulas, leaving some ambiguity about its unique role.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but lacks behavioral details. It states the action ('Create') but doesn't disclose if this modifies the original file, creates a new output, requires specific permissions, or handles errors. For a tool with 5 parameters and no annotations, this is a significant gap in transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all parameters. The description adds no additional meaning beyond implying grouping and aggregation, which is already covered by parameter names and descriptions. Baseline 3 is appropriate as the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Create pivot table with grouping and aggregation' clearly states the verb ('Create') and resource ('pivot table'), specifying the core functionality. It distinguishes from siblings like 'aggregate' or 'statistical_analysis' by focusing on pivot tables, though it doesn't explicitly contrast with them.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions 'comprehensive' analysis and 'industry benchmarks', but doesn't specify what ratios are calculated, how benchmarks are applied, output format, or any limitations (e.g., data requirements, processing time). This is inadequate for a tool that likely performs complex financial computations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with no wasted words. It front-loads the core purpose ('Perform comprehensive financial ratio analysis') and adds valuable context ('with industry benchmarks'), making it easy to parse quickly.

Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of financial ratio analysis, no annotations, and no output schema, the description is insufficient. It doesn't explain what ratios are computed, how benchmarks are sourced, or the return format, leaving significant gaps for an AI agent to use the tool effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents both parameters ('filePath' and 'sheet'). The description adds no additional parameter semantics beyond implying financial data is needed, which is already suggested by the tool's purpose. This meets the baseline for high schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose as 'Perform comprehensive financial ratio analysis with industry benchmarks', which includes a specific verb ('perform') and resource ('financial ratio analysis'). It distinguishes from many siblings like 'statistical_analysis' or 'trend_analysis' by specifying financial ratios, though it doesn't explicitly differentiate from 'dcf_analysis' or 'budget_variance_analysis' which are also financial tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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. It doesn't mention prerequisites (e.g., financial data format), exclusions, or comparisons to siblings like 'dcf_analysis' or 'budget_variance_analysis', leaving the agent to infer usage context solely from the tool name and description.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions searching for cells containing values, but doesn't describe what happens when matches are found (are they returned? highlighted? counted?), whether this is a read-only operation, what permissions might be needed, or any performance considerations. For a search tool with zero annotation coverage, this is insufficient behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is perfectly concise at 7 words, front-loading the core purpose with zero wasted words. Every word earns its place, making it immediately clear what the tool does without unnecessary elaboration.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of a search operation with 4 parameters, no annotations, and no output schema, the description is incomplete. It doesn't explain what the tool returns (list of cells? count? modified file?), doesn't mention performance implications for large files, and provides no context about error conditions or limitations. For a tool with this level of complexity and no structured metadata, the description should do more.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description coverage is 100%, so the schema already fully documents all 4 parameters. The description doesn't add any parameter semantics beyond what's in the schema - it doesn't explain the relationship between parameters or provide usage examples. With complete schema coverage, the baseline is 3 even without additional parameter information in the description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Search for cells containing a specific value' - this specifies the verb (search), resource (cells in files), and target (specific value). However, it doesn't differentiate from sibling tools like 'filter_rows' or 'find_duplicates' which might have overlapping search functionality, so it doesn't reach the highest clarity level.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 many sibling tools that might perform similar operations (filter_rows, find_duplicates, smart_data_analysis), there's no indication of when this specific search tool is appropriate versus other options. The description only states what it does, not when to choose it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the analysis types (trends, growth rates, etc.) but lacks details on execution behavior, such as computational requirements, output format, error handling, or any limitations (e.g., data size constraints). For a tool with no annotations, this leaves significant gaps in understanding how it operates.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that front-loads the core purpose without unnecessary details. It's appropriately sized for the tool's complexity, though it could be slightly more structured by separating analysis types for clarity. Overall, it earns its place without waste.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (5 parameters, no annotations, no output schema), the description is incomplete. It lacks information on behavioral traits, output format, and usage guidelines, which are crucial for effective tool invocation. Without annotations or output schema, the description should compensate more to provide a complete context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, meaning all parameters are documented in the input schema. The description adds no specific parameter semantics beyond implying analysis of time series data, which is already covered by the schema's descriptions (e.g., 'dateColumn' and 'valueColumn'). Thus, it meets the baseline of 3 without adding extra value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Analyze time series trends, growth rates, seasonality, and forecasting for sales and performance data.' It specifies the verb ('analyze') and resource ('time series trends... for sales and performance data'), making the function evident. However, it doesn't explicitly differentiate from sibling tools like 'statistical_analysis' or 'correlation_analysis', which might also handle time series data, so it misses full sibling distinction.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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. It mentions analyzing 'sales and performance data' but doesn't specify contexts, prerequisites, or exclusions compared to siblings like 'statistical_analysis' or 'smart_data_analysis'. Without such guidelines, users must infer usage from the purpose alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure but offers minimal information. It mentions 'cross-validate' which implies a read-only analysis operation, but doesn't specify whether this modifies files, requires specific permissions, has performance characteristics, or produces what kind of output. For a tool with 8 parameters and no output schema, this leaves 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that states the core purpose without unnecessary words. It's appropriately sized for a tool with comprehensive schema documentation and gets straight to the point. Every word earns its place in conveying the essential function.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a complex validation tool with 8 parameters, no annotations, and no output schema, the description is insufficient. It doesn't explain what 'data integrity' means in practice, what formats the validation report takes, whether this is a read-only operation, or what happens when validation fails. The agent must rely entirely on the input schema for operational details.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so all parameters are documented in the schema. The description adds no parameter-specific information beyond what the schema provides. It doesn't explain relationships between parameters (e.g., how 'keyColumns' interacts with 'autoDetectRelationships') or provide examples. The baseline of 3 is appropriate when the schema does all the parameter documentation work.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose as 'cross-validate data integrity across related files' which specifies the verb (cross-validate) and resource (data integrity across files). It distinguishes itself from siblings like 'find_duplicates' or 'data_profile' by focusing on cross-file validation rather than single-file operations. However, it doesn't explicitly differentiate from tools like 'correlation_analysis' or 'statistical_analysis' which might also involve multi-file comparisons.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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. It doesn't mention prerequisites (e.g., file formats supported), when-not-to-use scenarios, or comparisons to sibling tools like 'data_cleaner' or 'find_duplicates' that might handle related data quality tasks. The agent must infer usage from the purpose statement alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions file creation and format support but fails to address critical behaviors: whether it overwrites existing files, requires specific permissions, handles errors, or has rate limits. For a write operation, this leaves significant gaps in understanding its impact and constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that front-loads the core purpose and key capability (multi-sheet support). There is no wasted verbiage, making it easy to parse and understand at a glance.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a write tool with no annotations and no output schema, the description is incomplete. It lacks details on file overwriting behavior, error handling, format-specific constraints, and response structure. Given the complexity of 5 parameters and the absence of structured safety hints, more context is needed for reliable use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all 5 parameters. The description adds minimal value beyond the schema by implying parameter usage modes (e.g., single vs. multi-sheet), but doesn't clarify mutual exclusivity or provide examples. Baseline 3 is appropriate given the schema's comprehensive coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Write data') and target resource ('to a new CSV or Excel file'), with the specific capability of supporting multiple sheets for Excel. It distinguishes itself from sibling tools like 'read_file' by specifying a write operation, though it doesn't explicitly differentiate from 'write_multi_sheet' beyond mentioning multi-sheet support.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 like 'write_multi_sheet' or 'add_sheet', nor does it mention prerequisites or exclusions. It lacks context for choosing between single-sheet and multi-sheet modes, leaving usage decisions ambiguous.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but only states what the tool creates, not how it behaves. It doesn't disclose whether the tool overwrites existing files, requires specific permissions, handles errors, or has performance characteristics. 'Create' implies a write operation, but no further behavioral details are given.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence that efficiently communicates the core functionality without unnecessary words. Every element ('complex Excel file', 'multiple sheets', 'formulas', 'inter-sheet references') contributes directly to understanding the tool's purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 3 parameters, no annotations, and no output schema that creates complex Excel files, the description is insufficient. It doesn't explain what happens if the file already exists, what the return value is, error conditions, or limitations. The absence of annotations means the description should provide more behavioral context than it does.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, providing complete parameter documentation. The description adds minimal value beyond the schema by mentioning 'multiple sheets, formulas, and inter-sheet references' which aligns with the sheets and sheetReferences parameters, but doesn't provide additional semantic context or usage examples.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Create') and resource ('complex Excel file') with specific features ('multiple sheets, formulas, and inter-sheet references'). It distinguishes from basic write_file by specifying Excel capabilities, but doesn't explicitly differentiate from other Excel-related siblings like add_sheet or format_cells.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like write_file (for simpler files) or add_sheet (for adding to existing files). The description implies it's for complex Excel creation but doesn't provide explicit usage context or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It mentions chunking for large files, which is useful, but doesn't address critical aspects like error handling (e.g., what happens if file doesn't exist), performance characteristics, memory usage, or output format details. For a file reading tool with zero annotation coverage, this leaves 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is perfectly concise - a single sentence that communicates the core functionality with no wasted words. It's front-loaded with the main purpose and includes the key additional feature (chunking) efficiently.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity (file reading with chunking options), 100% schema coverage for parameters, but no annotations and no output schema, the description is minimally adequate. It covers what the tool does but lacks important context about behavior, error conditions, and output format that would help an agent use it effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description mentions 'optional chunking for large files' which relates to the offset and limit parameters, but doesn't add meaningful semantics beyond what the 100% schema coverage already provides. The schema descriptions thoroughly document each parameter's purpose and optionality, so the description adds minimal value here, meeting the baseline expectation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose with a specific verb ('Read') and resource ('CSV or Excel file'), and mentions optional chunking for large files. However, it doesn't explicitly differentiate from sibling tools like 'read_file_chunked' or 'get_file_info', which reduces clarity about when to choose this specific tool.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 sibling tools like 'read_file_chunked', 'get_file_info', and 'bulk_aggregate_multi_files', there's no indication of when this tool is preferred or what distinguishes it from similar file reading operations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It mentions 'error handling and fuzzy matching' but doesn't specify what errors are handled, what fallbacks are used, how fuzzy matching works, or any performance characteristics. For a tool with 8 parameters and no annotations, this leaves 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient phrase that packs key information: the core function (VLOOKUP), setup/execution scope, and two main features. Every word earns its place with no redundancy or wasted space.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 8 parameters, no annotations, and no output schema, the description is moderately complete. It identifies the tool's domain and key features but lacks details on behavior, output format, and usage context. Given the complexity, it should provide more guidance on what the tool returns and how it differs from alternatives.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description coverage is 100%, so all parameters are documented in the schema. The description adds minimal value beyond the schema by mentioning 'fuzzy matching' and 'error handling' which correspond to parameters, but doesn't provide additional semantic context. This meets the baseline for high schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose as 'Intelligent VLOOKUP setup and execution with error handling and fuzzy matching', which specifies the verb (VLOOKUP setup/execution) and key capabilities. However, it doesn't explicitly differentiate from sibling tools like 'search' or 'find_duplicates' that might also perform lookups, keeping it from a perfect score.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 many sibling tools like 'search', 'find_duplicates', and 'smart_data_analysis' that might handle similar tasks, there's no indication of specific contexts, prerequisites, or exclusions for this VLOOKUP tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. While 'Check status' implies a read-only operation, it doesn't specify what 'status' entails (e.g., availability, health, usage limits), whether authentication is required, or what the response format looks like. For a tool with zero annotation coverage, this leaves 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with zero waste: 'Check status of available AI providers'. It's front-loaded with the core action and resource, making it immediately understandable without unnecessary elaboration.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (0 parameters, no output schema), the description is minimally adequate. However, with no annotations and no output schema, it should ideally provide more context about what 'status' means and what information is returned. The description is complete enough for basic understanding but lacks depth for effective agent use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has 0 parameters with 100% schema description coverage, so the schema already fully documents the lack of inputs. The description doesn't need to add parameter semantics, and it appropriately doesn't mention any parameters. The baseline for 0 parameters is 4, as there's nothing to compensate for.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose as 'Check status of available AI providers', which is a specific verb ('Check') and resource ('status of available AI providers'). However, it doesn't differentiate from sibling tools, as none of the listed siblings appear to perform similar status-checking functions for AI providers.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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. It doesn't mention prerequisites, timing considerations, or any context for when this status check is needed versus other operations. The tool stands alone in its function among siblings, but this isn't explicitly stated.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but only states what the tool does, not how it behaves. It doesn't disclose whether this modifies files in-place, requires write permissions, handles errors, or provides any feedback. For a tool that modifies Excel files, this is a significant gap in behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that immediately conveys the core functionality. Every word earns its place with no redundancy or unnecessary elaboration, making it perfectly front-loaded and concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool that modifies Excel files with 6 parameters and no annotations or output schema, the description is insufficient. It doesn't explain what happens after execution (e.g., file saved, success confirmation), error conditions, or behavioral constraints, leaving critical gaps for an agent to use it effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all 6 parameters. The description adds no parameter-specific information beyond what's already in the schema descriptions, maintaining the baseline score of 3 for high schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the specific action ('Automatically adjust column widths to fit content') and the target resource ('in Excel files'). It distinguishes itself from siblings like 'format_cells' or 'get_range' by focusing exclusively on column width optimization.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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. It doesn't mention prerequisites (e.g., file must exist), compare to manual formatting, or suggest when to use sibling tools like 'format_cells' for other formatting needs.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but offers minimal behavioral insight. It mentions 'parallel' processing but doesn't disclose error handling, performance characteristics, memory usage, or output format. For a tool with 6 parameters and no output schema, this leaves significant gaps in understanding how the tool behaves.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that directly states the tool's purpose without unnecessary words. It's appropriately sized and front-loaded with the core functionality, making it easy to parse quickly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a complex tool with 6 parameters, no annotations, and no output schema, the description is inadequate. It doesn't explain what the tool returns, how errors are handled, what file formats are supported, or the implications of the 'parallel' processing. The agent would struggle to use this tool effectively without trial and error.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, providing good parameter documentation. The description adds minimal value beyond the schema, only implying that aggregation happens 'across multiple files' which is already clear from the 'filePaths' parameter. No additional syntax, format, or constraint details are provided beyond what's in the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb ('aggregate') and resource ('same column across multiple files'), specifying the parallel processing aspect. It distinguishes from sibling 'aggregate' (which likely handles single files) by emphasizing multi-file processing, though it doesn't explicitly mention this distinction.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for multi-file column aggregation, suggesting when to use it over single-file tools. However, it lacks explicit guidance on when to choose this over sibling 'bulk_filter_multi_files' or other aggregation tools, and doesn't mention prerequisites like file format compatibility or performance considerations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action but omits critical details such as error handling (e.g., for invalid file paths or unsupported formats), performance considerations (e.g., for large files), or output format. This is a significant gap for a tool with potential file I/O operations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that front-loads the core purpose without unnecessary words. It avoids redundancy and wastes no space, making it easy to parse quickly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (file I/O with potential format variations) and lack of annotations or output schema, the description is incomplete. It fails to address behavioral aspects like error cases, output structure, or limitations, leaving gaps that could hinder effective agent use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, with clear parameter documentation in the input schema. The description adds no additional meaning beyond implying the tool works with CSV or Excel files (hinted by 'sheet' parameter), but this is already covered in the schema. Baseline 3 is appropriate as the schema adequately defines parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the specific action ('Get') and resource ('column headers (first row) of a file'), distinguishing it from siblings like 'get_cell' or 'get_range' by focusing on header extraction rather than cell values or data ranges. It precisely defines the tool's function without ambiguity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 like 'read_file' or 'get_file_info', which might also provide header information. It lacks context on prerequisites (e.g., file format compatibility) or exclusions, leaving usage decisions to inference.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 mentions chunking to avoid token limits, which is useful behavioral context, but lacks details on file formats (only implied via parameters), error handling, performance traits, or output structure. For a tool with 4 parameters and no annotations, this 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that front-loads the core purpose. Every word earns its place, with no redundancy or unnecessary elaboration, making it highly concise and well-structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 4 parameters, no annotations, and no output schema, the description is incomplete. It doesn't cover behavioral aspects like file format support (beyond CSV/Excel implied in schema), chunking mechanics, or return values. For a tool with moderate complexity, this leaves significant gaps for an AI agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all parameters. The description adds no parameter-specific information beyond what's in the schema (e.g., it doesn't explain chunkIndex or chunkSize behavior further). Baseline 3 is appropriate as the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Read large files in manageable chunks to avoid token limits.' It specifies the verb ('read'), resource ('large files'), and key constraint ('chunked'). However, it doesn't explicitly differentiate from sibling 'read_file' (which likely reads entire files), though the chunking aspect implies a distinction.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage context ('large files... to avoid token limits'), suggesting this tool is for handling files too large for standard processing. It doesn't explicitly state when to use it versus alternatives like 'read_file' or provide exclusions (e.g., for small files). The guidance is present but not comprehensive.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 mentions the tool explains formulas in plain English but does not disclose behavioral traits such as whether it uses external AI services (implied by the provider parameter), potential rate limits, error handling for invalid formulas, or output format. This leaves significant gaps in understanding how the tool behaves.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that front-loads the core purpose without unnecessary words. Every part earns its place by clearly stating the tool's function, making it easy to understand at a glance.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of explaining formulas (which may involve AI providers) and the lack of annotations and output schema, the description is incomplete. It does not address how explanations are generated, what the output looks like, or any limitations, which are crucial for an AI agent to use the tool effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents both parameters thoroughly. The description does not add meaning beyond the schema, as it does not explain parameter interactions, default behaviors for the optional provider, or examples of formula formats. Baseline 3 is appropriate given the high schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the specific action ('explain') and resource ('Excel formula'), with the qualifier 'in plain English' distinguishing it from sibling tools like evaluate_formula (which likely computes results) or parse_natural_language (which might convert text to formulas). It directly answers what the tool does without being tautological.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for understanding Excel formulas, but it does not explicitly state when to use this tool versus alternatives like evaluate_formula (for computation) or other analysis tools. No exclusions or prerequisites are mentioned, leaving the context somewhat open-ended.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
