Server Quality Checklist

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

Latest release: v0.2.0
Disambiguation2/5
With 67 tools, many overlap in purpose (e.g., over 20 chart creation tools, multiple search tools, multiple transform shorthands). Despite detailed descriptions, an agent would struggle to reliably distinguish between similar tools like 'create_chart' and 'create_animated_chart' or 'filter_data_tool' vs 'transform_data(operation="filter")'.
Naming Consistency4/5
Most tools follow a clean verb_noun pattern with underscores (e.g., search_datasets, create_chart, get_resource_data). A few deviations like 'health_check' and 'get_config_tool' are minor, but the overall naming system is predictable and readable.
Tool Count2/5
67 tools is excessive for a data MCP server. Many highly specialized tools (e.g., 11 distinct 3D chart types) could be consolidated into parameterized versions. The sheer number overwhelms the tool surface and reduces discoverability.
Completeness5/5
The tool set covers the full lifecycle of working with Serbian open data: discovery (search, browse, suggest), retrieval (get, preview, summary), transformation (filter, sort, group, aggregate), analysis (forecast, benchmark, compare, insight extraction), and extensive visualization (maps, charts, 3D, dashboards, infographics, export). No obvious gaps for its intended domain.
Average 3.9/5 across 67 of 67 tools scored. Lowest: 2.8/5.

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, the description carries full burden for behavioral disclosure. It only lists operations and does not mention any behavioral traits such as side effects, immutability, or return behavior beyond what the schema provides.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, making it concise, but it lacks crucial details that would help an agent select and invoke the tool correctly. The brevity comes at the expense of informativeness.
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 has 8 parameters, many sibling tools, and no annotations, the description is incomplete. It does not clarify the meta-operation nature, prerequisites, or when to use combined operations.
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 coverage is 100%, so baseline is 3. The description adds no additional meaning beyond what is in the schema; it does not explain which parameters correspond to which operation or provide usage context.
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 data transformations: filter, group, aggregate, sort, or select columns. It uses a verb and resource, but does not differentiate from sibling tools like filter_data_tool or sort_data_tool, which individually perform each operation.
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 the many sibling tools that each handle a single operation. There is no mention of combining operations or when this meta-tool is preferable.
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. It only states that the tool adds an annotation with an optional arrow, but does not disclose behavioral traits such as whether the input figure is mutated, what the function returns, or any side effects. The return value and state changes are not mentioned.
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 very concise, consisting of two sentences that convey the core purpose and a key feature. It is front-loaded and efficient, though it could be slightly more informative given the tool's parameter complexity.
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 has 7 parameters, 100% schema coverage, and an output schema, the description is adequate but incomplete. It does not explain the return value, that the figure is manipulated, or that the figure should come from create_chart(). Sibling tools and usage context are absent.
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 baseline. The description adds minimal context by describing the annotation as a 'text box with optional arrow,' which aligns with the 'show_arrow' parameter. It does not add significant meaning beyond what the schema already defines for parameters like x, y, figure, etc.
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 adds a callout annotation to a chart for storytelling, with a text box and optional arrow. It specifies the resource (chart) and action (add callout annotation), but does not explicitly differentiate from the sibling tool 'add_chart_callouts', which may overlap in functionality.
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 'add_chart_callouts', 'add_chart_highlight_zone', or 'add_chart_threshold_line'. There is no mention of prerequisites, context, or when not to use this 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, the description bears full burden. It mentions 'smooth transitions and play/pause' but fails to disclose output format, performance implications, data requirements (e.g., time series), or limitations. The existing output schema is not leveraged for behavioral clues.
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?
Extremely concise single sentence. No wasted words, but the brevity sacrifices completeness. Scores high for conciseness, not for structure.
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 9 parameters, many sibling tools, and an output schema, the description is too sparse. It does not explain animation types, data formatting, or how to use the output. The output schema exists but is not referenced to aid completeness.
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 coverage is 100%, so parameters are well-documented. The description adds no additional meaning beyond what the schema provides, but the schema itself is sufficient. Baseline 3 applies.
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 'create' and resource 'animated charts' with specific features ('smooth transitions and play/pause'). It distinguishes from static chart tools but not from other animated chart variants among 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 like 'create_chart' or other chart creation tools. The description does not provide context on preferred 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?
With no annotations, the description carries full burden for behavioral disclosure. It does not mention whether the tool is read-only, requires authentication, or has any side effects. The return structure is shown, but the underlying process (e.g., AI generation, data size limits) is not disclosed.
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 extremely concise: one sentence plus a return type annotation. It front-loads the purpose effectively. However, it could be slightly more informative without becoming verbose, e.g., noting that input must be a list of dicts from 'get_resource_data'.
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 has 5 parameters and a defined output, the description is minimally adequate. It explains the return structure (which acts as an output schema), but it does not clarify the role of optional parameters like 'time_column' or 'entity_column' in generating the narrative. The schema descriptions help, but the tool could benefit from a brief usage hint.
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 coverage is 100%, so all parameters have descriptions. The description adds no extra meaning beyond the schema, such as explaining how 'time_column' influences the narrative or formatting expectations. Baseline 3 is appropriate since the schema already documents 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 tool generates a 'data story' with headline, big number, and narrative text. This distinguishes it from sibling tools like 'create_chart' for visualizations, though it could more explicitly differentiate from 'extract_data_insights' or 'data_profile' which also handle data summaries.
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 over alternatives like 'extract_data_insights' or 'get_data_summary'. There are no prerequisites, exclusions, or context about appropriate use cases, leaving the agent to infer from the name 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 present, so the description carries full responsibility. It only mentions that detail_level controls response size, but lacks disclosure of error handling, default behavior, or any side effects. Important behavioral aspects like required permissions or response format are missing.
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 very concise with two front-loaded sentences. It efficiently conveys the basic purpose and a key parameter insight, but could include more useful information without losing conciseness.
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 retrieving dataset details with multiple detail levels, the description is incomplete. It lacks explanation of the detail_level values and does not leverage the existence of an output schema to reduce need for return value description. The description should at least define what each detail_level returns.
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 coverage is 100%, so baseline is 3. The description adds that detail_level controls response size, which provides some context beyond the schema. However, it does not explain the meaning of each level (metadata, resources, preview, summary), limiting the added 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 verb 'Get' and resource 'dataset details', making the purpose identifiable. However, it does not differentiate from sibling tools like get_dataset_resources or preview_dataset, which also retrieve dataset-related information.
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. For instance, it is unclear when to prefer get_dataset over get_dataset_resources or preview_dataset.
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 should reveal behavior beyond input/output. It does not mention whether the tool is read-only, how it handles missing values, or any required data formats. Only output structure is provided.
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?
Two sentences, front-loaded with purpose and output fields. No superfluous information.
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?
Adequate for a straightforward tool with output schema. Missing details on error handling, data requirements, and best practices, but sufficient for basic understanding.
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?
Schema coverage is 100% with basic descriptions. The tool description adds context by giving examples of benchmarks (EU average, regional, custom), augmenting the 'benchmarks' parameter's meaning. This adds value beyond 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 states the tool compares data against benchmarks and lists return fields. It gives examples like EU average, regional, custom, which clarifies scope. However, it could be more precise about what 'compare' entails (e.g., statistical 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 on when to use this tool versus alternatives like compare_datasets or compute_metrics. The description does not mention prerequisites 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 bears full responsibility for disclosing behavior. It only says 'Get', implying a read-only operation, but does not confirm safety, required permissions, or potential side effects. The description lacks critical behavioral details.
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, short sentence that efficiently conveys the tool's purpose without any fluff. It is well front-loaded and every word adds value.
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 that the tool has no parameters and an output schema exists, the description provides a basic understanding of the output. However, it lacks context about the scope ('portal overview') and does not explain how this tool differs from similar ones like 'get_catalog_stats'. The description is minimally adequate.
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 input schema has zero parameters with 100% schema coverage. For no-parameter tools, the baseline is 4. The description does not need to add parameter semantics, but it does clarify the output, which is relevant context.
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 that the tool retrieves dataset and organization counts for the portal overview. The verb 'Get' and the specific resources (dataset and organization counts) make the purpose clear. However, it does not explicitly differentiate from the sibling tool 'get_catalog_stats', which might have similar functionality.
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. There is no mention of prerequisites, limitations, or context where the tool is appropriate. The user must infer usage from the name and vague reference to 'portal overview'.
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 bears full responsibility for behavioral disclosure. It only says 'Find all datasets...' and 'Returns: Same shape as search_datasets()', with no mention of read-only nature, authentication needs, rate limits, or error behavior. Critical behavioral context is missing.
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 no wasted words. It front-loads the core purpose in the first sentence, then provides a helpful list of common tags and a clear reference to output shape. Every sentence earns its place.
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 has 3 parameters, an output schema (referenced), and no annotations, the description is adequate but incomplete. It explains what the tool does and references the output shape, but lacks behavioral context (e.g., read-only, rate limits) and usage guidance. The common tags list adds some completeness, but overall it could do more to fully equip an agent.
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 input schema already covers all 3 parameters with descriptions (100% coverage). The description adds value by listing common tags (e.g., 'statistika', 'budžet') which provides practical examples for the 'tags' parameter. It also clarifies the return format by referencing 'search_datasets()', helping users anticipate output structure.
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 states it finds datasets by tags (specific verb 'Find' and resource 'datasets tagged'), and adds 'regardless of publisher' which hints at a differentiating scope. However, it does not explicitly contrast with sibling tools like 'search_datasets' or 'intelligent_search', leaving room for ambiguity. The common tags list aids understanding but does not fully distinguish the tool's 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?
The description provides no explicit guidance on when to use this tool versus alternatives. There is no mention of when to prefer tag-based search over full-text search (search_datasets) or other discovery tools. Users must infer usage from the tool's name and description 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 must fully disclose behavioral traits. It mentions format dependencies (xlsx requires openpyxl) but omits critical details such as where files are saved, whether they overwrite existing files, authentication requirements, or the return value (despite an output schema existing). The description fails to convey important side effects 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 extremely concise: two sentences that front-load the purpose and then list the formats. Every sentence earns its place with no filler or redundancy.
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 (3 parameters, all documented in schema), the description is minimally adequate. It explains formats and data sources but lacks details about file path, overwrite behavior, and permissions. The presence of an output schema is unmentioned. Overall, functional but with gaps.
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 baseline is 3. The description adds context for the format parameter by explaining format characteristics ('csv universal, json API-friendly, xlsx requires openpyxl'), which adds value. However, it does not enrich the data or filename parameters beyond what the schema provides. Overall, moderate added value.
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 tool's purpose: 'Save data from get_resource_data() or transform_data() to file.' It specifies the verb 'Save' and the resource 'data to file', and it distinguishes from sibling tools like export_visualization (which exports charts) and export_chart_pdf (which exports PDFs of charts).
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 does not provide any guidance on when to use this tool versus alternatives. It mentions data sources but lacks explicit when-to-use or when-not-to-use instructions. No alternatives are named, and there is no context about excluding other export 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 provided; description only states action and return type. Does not disclose side effects, in-place mutation vs. new dict, or any other behavioral traits.
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?
Three short sentences, front-loaded with the action. Every sentence adds value; no waste.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given parameter count and output schema existence, the description is mostly complete. Missing explicit comparison with sibling tools that add other chart elements.
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 covers 100% of parameters with descriptions. The tool description adds no extra parameter meaning beyond what is already in the input 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 'Add a horizontal threshold/reference line with label', specifying the verb and resource. It is distinguishable from siblings like add_chart_annotation, but does not explicitly differentiate itself.
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?
Provides example use cases (EU average benchmark, target/goal line, critical threshold), implying when to use. However, no guidance on when not to use or alternatives among siblings.
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 provided, so description must disclose behavior. Only mentions output format (HTML) but not side effects, permissions, or data handling. Lacks details on how panels are built.
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?
Two short sentences, front-loaded with action. No extraneous 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?
Despite output schema existing, the description is too minimal for a dashboard builder. Does not cover panel configuration, data sources, or theming.
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 coverage is 100%, providing baseline of 3. Description adds that panels can be chart, HTML, or big number, which provides context beyond schema, but doesn't detail panel dict structure.
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?
Clearly states 'Build multi-panel dashboard HTML' with specific panel types (chart, HTML, big number). Distinguishes from sibling tools like create_chart (single chart) or build_infographic.
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?
Implied usage for creating dashboards but no explicit when-to-use or alternatives. Does not mention when not to use 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?
No annotations are provided, so the description must convey behavioral traits. It describes what the tool shows but does not disclose whether it is read-only, requires authentication, or has any side effects. The read-only nature is implied but not explicit.
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?
Two sentences with no wasted words. First sentence states core action, second lists output details. Front-loaded and efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema, the description appropriately skips return value details and instead lists what differences are shown. It covers core functionality but could mention prerequisites like dataset existence.
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 coverage is 100% and both parameters have clear descriptions referencing 'search_datasets'. The tool description does not add additional meaning beyond the schema, so baseline 3 applies.
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 'compare' and the resource 'datasets', and lists specific comparison dimensions (publisher, tags, resource count, formats, quality). However, it does not distinguish itself from sibling tool 'compare_cross_dataset', which may lead to confusion about when to use which tool.
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 the tool is for choosing the best dataset by comparing differences, providing a usage context. But it lacks explicit when-to-use or when-not-to-use guidance, and does not mention alternatives like 'compare_cross_dataset'.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full responsibility. It mentions the method ('regression') and lists return fields (forecast_data, growth_rate, etc.), which informs about outputs. However, it does not disclose assumptions, limitations (e.g., short data), or the existence of a method parameter (linear/exponential) beyond the schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is brief and to the point, with no wasted words. The quote adds a touch of context. Could be slightly improved by removing the quote to save space, but it remains concise.
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 complexity (5 parameters, output schema), the description covers the basic purpose and output structure but lacks details on parameter choices (e.g., linear vs exponential) and interpretation of outputs like r_squared, which might be needed for proper 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 all parameters. The description adds no extra meaning to the parameters themselves; it only provides overall context. Baseline 3 is appropriate.
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 ('Forecast future values using regression'), identifying the resource (future values) and the method. It is distinct from sibling tools like 'benchmark_data' or 'compare_datasets' but does not explicitly differentiate itself.
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 quote 'At this rate, X by 2030' hints at a typical use case, but there is no explicit guidance on when to use this tool vs alternatives, or when not to use it. Sibling tools like 'compute_metrics' or 'aggregate_data_tool' could overlap, but no comparison is made.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Description discloses return structure (filepath, layer_count, title) and the interactive toggle feature, but does not mention permissions, rate limits, or side effects. No annotations are present, so the description carries the burden for behavioral disclosure, but it misses some aspects like whether the tool saves files or requires authentication.
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: two sentences plus a return format list, all front-loaded. No unnecessary words, every sentence earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the main purpose, layer structure, and return values. However, it lacks details on theme options, filename formatting, and data preparation requirements. Despite having an output schema (implied), minor gaps remain for a fully self-contained definition.
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 description adds meaningful structure for the 'layers' parameter beyond the schema's 'List of layer dicts', specifying fields like data, name_column, value_column, label, colorscale. Other parameters have adequate schema descriptions, so the description provides additional valuable context.
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?
Description clearly states it creates a multi-layer choropleth map with toggle buttons, distinguishing it from sibling map tools like create_bubble_map or create_serbia_map. However, it lacks an explicit verb like 'Creates', but the noun phrase implies creation.
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 explicit guidance on when to use this tool versus alternatives like create_bubble_map or create_serbia_map. The description implies it's for multi-layer choropleths, but does not specify when not to use it or mention any prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It describes the output pattern (text left, charts right) and mentions parameter defaults, but it does not disclose behaviors like file overwriting, validation of steps, required permissions, or error handling. The presence of an output schema (indicated in context) is not mentioned, and step structure is left undefined.
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 two sentences, each adding value: the first states the core action, the second provides a concrete pattern reference. No redundant words; it is efficiently scoped.
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 creates a multi-section interactive story, the description covers the basic layout and parameters. However, it lacks details about the step structure (required nested keys), expected behavior with empty steps, and output handling. With an output schema present, some burden is relieved, but step semantics remain underspecified.
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 baseline is 3. The description does not add significant meaning beyond what param descriptions provide—it repeats the purpose but doesn't clarify the structure of 'steps' or usage of other params. The step object is left as 'additionalProperties: true' with no extra guidance.
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 tool creates a 'scroll-driven HTML data story (scrollytelling)' with a specific pattern (text left, charts right). It uses a specific verb 'create' and resource, and the title and description distinguish it from sibling tools like create_chart or build_dashboard.
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?

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 provided; description carries full burden. It fails to disclose side effects like file overwriting, permissions, storage location, or error handling. Only states it saves to a file, but no details on return values or behavior, despite output schema existence.
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 of 9 words, no fluff. Action is front-loaded. Every word serves a purpose.
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 existence of output schema (covers return values) and full parameter descriptions, the minimal description is adequate for a simple file save. However, lacks behavioral details that might be needed for robust usage, such as overwrite behavior or error messages.
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?
Schema coverage is 100%. Description adds value by clarifying 'Plotly figure dict from create_chart()' for figure, specifying format values as 'html' or 'json', and noting filename is 'without extension'. This goes beyond schema descriptions.
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?
Description explicitly states 'Save a chart from create_chart() to a file', specifying the action (save), source (create_chart()), and output (file). This clearly distinguishes from sibling tools like export_data (data export) and export_chart_pdf (PDF specific).
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 vs alternatives such as export_chart_pdf or export_to_datawrapper. Does not mention prerequisites, when not to use, or context for selection among many export-related siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses ordering and parameters but doesn't add behavioral details like authentication needs, data scope, or pagination behavior beyond what schema provides. No annotations to supplement.

Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Bubble map of Serbia' and explains that circle size represents magnitude, specifying the resource and distinguishing it from generic mapping tools. It also mentions avoiding large-district bias, adding unique context.
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 visualizing numeric magnitudes on a map of Serbia but does not explicitly state when to use this tool over siblings like create_serbia_map or when not to use it. No alternatives or exclusions are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Since no annotations are provided, the description carries the full burden. It discloses that the tool creates and publishes a chart, and lists supported chart types. However, it does not mention potential side effects (e.g., overwriting existing charts), rate limits, or failure behavior. The information is adequate but not exhaustive.
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 concise and well-structured: it opens with the core purpose, then provides necessary details (API token requirement and supported chart types). Every sentence adds value with no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema (so return values need not be described), and 100% schema coverage, the description covers essential context (environment variable, chart type options). It is mostly complete for an external export tool, though missing error handling details.
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?
With 100% schema description coverage, the parameters are already documented. The description adds value by explaining that 'data' should come from get_resource_data() and by listing all supported chart types for the chart_type parameter, enhancing clarity beyond the schema.
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 tool's purpose: exporting data to Datawrapper to create charts, publish them, and return embed URLs. It distinguishes from sibling tools like create_chart and export_data by specifying the external platform and embed output.
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?

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, and the description only notes it 'filters rows by criteria' without disclosing behavioral details such as mutability, side effects, or error handling. The description adds minimal value beyond the schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences efficiently convey the purpose and relationship to transform_data. No wasted words, and the most important information is front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple filtering tool with two parameters and an output schema, the description is adequate. It could elaborate on filter syntax (e.g., logical operators) but remains sufficiently complete given the schema coverage.
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 coverage is 100%, so the description adds no extra meaning beyond the existing schema descriptions. The baseline score of 3 is appropriate.
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 tool's purpose: 'Filter rows by criteria.' It also specifies it is a shorthand for transform_data(operation='filter'), which distinguishes it from sibling tools like transform_data and aggregate_data_tool.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description indicates this tool is an alternative to transform_data with a specific operation, providing some usage context. However, it does not explicitly state when to prefer this over siblings like group_data_tool or sort_data_tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It notes the output structure (iframe_code, width, height, note) and that it renders via Plotly.js CDN. However, it does not mention any dependencies, limitations (e.g., requires internet access for CDN), or side effects. The transparency is adequate but not comprehensive.
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?

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with high schema coverage and an output schema, the description covers the essential input (figure from create_chart()) and output structure. It implies a prerequisite (a chart must be created first). One could argue it could mention the embed code's reliance on the Plotly CDN, but overall it is sufficiently complete for an agent to use correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the baseline is 3. The description adds minimal extra meaning beyond the schema: it notes that 'figure' is a Plotly figure dict from create_chart(), which is already in the parameter description. The description does not elaborate on parameter usage or constraints, so it scores at baseline.
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 tool generates iframe embed code for sharing a chart. It specifies the resource (embed code) and the action (generate for sharing). Among sibling tools like export_chart_pdf or export_visualization, this one uniquely focuses on embedding, so it is well-differentiated.
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 indicates the embed snippet is for websites/blogs and is self-contained, giving a sense of when to use. However, it does not explicitly compare to alternatives (e.g., export tools) or state when not to use it. The guidance is implied but not explicit enough for an agent to easily decide between this and similar export 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?
With no annotations provided, the description carries full burden for behavioral disclosure. It states 'Check' implying a read-only operation, but does not disclose specifics such as whether authentication is required, what exactly is checked (e.g., ping vs. full API test), or possible side effects. The description is too minimal to fully inform an AI agent of behavioral traits.
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: one short sentence that directly states the purpose. No filler or redundancy. Ideal length for this simple tool.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (no parameters, clear purpose, and an output schema exists to define return values), the description is sufficiently complete. It covers the essential action and resource. However, it could benefit from a small note on when this check is useful (e.g., before other operations), but not strictly necessary.
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 no parameters, so the baseline is 4. The description adds no parameter-level information because none is needed. The input schema already provides full coverage (100%) with zero 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 tool's purpose: 'Check server health and API connectivity.' It uses a specific verb ('Check') and resource ('server health and API connectivity'), and is distinct from sibling tools which are all about data visualization and manipulation.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description includes an example showing typical input and output, indicating it returns a list of matching dataset titles. It does not disclose behaviors like handling of no matches, maximum suggestions beyond the size parameter, or whether it works only for Serbian terms. Given no annotations, more behavioral detail would improve transparency.
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

Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has an output schema, so return values are documented elsewhere. The description covers the core autocomplete functionality adequately. It could mention the output schema or provide more on matching logic, but overall it is sufficient for a simple tool.
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. The description adds an example of usage and contextualizes the query parameter for Serbian terms, but does not provide additional meaning beyond the schema. Baseline score of 3 is appropriate.

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?
Concise and front-loaded with key information. The first sentence captures the essence. Could trim the second sentence slightly, but overall efficient.
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?
Covers purpose, usage, and return values (with output schema). Does not address error conditions, input validation (e.g., requirement for complete grid), or performance considerations. Adequate but incomplete for a tool with 8 parameters.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5

Explicitly says 'ALWAYS use after get_resource_data() and before create_chart()', providing clear sequential context and when-to-use guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
