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 that the tool returns a 'comparison table' but doesn't specify data sources (e.g., World Bank), time frames, error handling, rate limits, or authentication needs. For a tool with no annotations, this leaves significant gaps in understanding its operational behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured and front-loaded, starting with a clear purpose sentence, followed by concise sections for 'Args' and 'Returns'. Each sentence adds value without redundancy, making it easy to scan and understand quickly. No wasted words or unnecessary details are present.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has an output schema (implied by 'Returns' in the description), the description doesn't need to detail return values. However, with no annotations and only basic parameter semantics, it lacks information on data sources, constraints, or error conditions. For a comparison tool with 2 parameters, it's minimally adequate but could be more comprehensive.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds meaningful context beyond the input schema, which has 0% description coverage. It explains that 'countries' should be a list of country codes with an example (['USA', 'CHN', 'IND']), and 'indicator' is a World Bank indicator code with a default (GDP). This compensates well for the schema's lack of descriptions, though it doesn't detail all possible indicator codes or country code formats.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Compare an economic indicator across multiple countries.' It specifies the verb ('compare') and resource ('economic indicator across multiple countries'), making the function unambiguous. However, it doesn't explicitly differentiate from sibling tools like 'get_country_indicators' or 'query_worldbank', which might offer similar functionality.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It mentions a default indicator (GDP) but doesn't specify scenarios where this tool is preferred over siblings like 'get_country_indicators' or 'query_worldbank', nor does it outline prerequisites or exclusions. Usage is implied through the description but not explicitly stated.

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

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

No annotations are provided, so the description carries the full burden. It mentions the tool fetches data from NASA's APOD service and describes the return format, but lacks details on rate limits, authentication needs, error handling, or data freshness. It adequately covers basic behavior but misses operational constraints.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is efficiently structured with a clear purpose statement followed by labeled sections for arguments and returns. Every sentence adds value without redundancy, and it's front-loaded with the core functionality, 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.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's low complexity (1 optional parameter) and the presence of an output schema (which handles return values), the description is largely complete. It covers purpose, parameter usage, and return content. However, it could improve by addressing behavioral aspects like rate limits or error scenarios, which are not covered by annotations or schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage for the single parameter, the description compensates by specifying the parameter's purpose ('Optional date in YYYY-MM-DD format'), default value ('default: today'), and format. This adds meaningful context beyond the bare schema, though it doesn't detail edge cases like invalid dates.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific action ('Get NASA's Astronomy Picture of the Day') and identifies the exact resource (APOD). It distinguishes itself from sibling tools like 'get_mars_rover_photos' or 'query_nasa' by focusing on a specific NASA service rather than general queries or other NASA data sources.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for retrieving APOD data, but provides no explicit guidance on when to use this tool versus alternatives like 'query_nasa' or 'search_nasa_images'. It lacks any mention of prerequisites, exclusions, or comparative context with sibling tools, 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.

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 the tool fetches data (implied read-only) and specifies default indicators, but lacks details on rate limits, authentication needs, error handling, or data freshness. This is inadequate for a tool with external API dependencies.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is efficiently structured with a clear opening sentence, followed by well-organized 'Args' and 'Returns' sections. Every sentence adds value without redundancy, making it easy to parse and front-loaded with essential information.

However, it lacks behavioral details like rate limits or error cases, which are important for API-based tools, slightly reducing completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds significant value beyond the input schema, which has 0% coverage. It explains 'country' accepts codes or names with examples ('USA', 'CHN'), clarifies 'indicators' is optional with defaults (GDP, population, poverty), and provides semantic context not in the schema. This compensates well for the low schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Get economic indicators') and resource ('for a country from the World Bank'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'query_worldbank' or 'get_population', which might offer overlapping functionality.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives like 'query_worldbank' or 'get_population'. The description mentions the data source (World Bank) but doesn't specify use cases, exclusions, or comparisons with siblings, leaving the agent to infer usage context.

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

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool retrieves 'detailed metadata and download links', which is helpful, but it doesn't mention important behavioral traits such as whether this is a read-only operation, potential rate limits, authentication needs, or error handling. 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.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that there's an output schema (which handles return values), the description doesn't need to detail outputs. However, for a tool with no annotations and a simple input schema, the description adequately covers the basics but could be more complete by addressing behavioral aspects like read-only nature or error conditions, which are important for safe and effective use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds meaningful context for the single parameter 'dataset_id' by specifying it should come 'from search results', which clarifies its source and usage beyond the schema's basic type definition. Since there's only one parameter and schema description coverage is 0%, this additional semantic information is valuable and compensates well for the lack of schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with a specific verb ('Get') and resource ('detailed information about a specific Data.gov dataset'), making it easy to understand what the tool does. However, it doesn't explicitly differentiate from sibling tools like 'query_datagov' or 'search_datasets', which might have overlapping functionality.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage by mentioning 'dataset_id (from search results)', suggesting it should be used after searching for datasets. However, it doesn't provide explicit guidance on when to use this tool versus alternatives like 'query_datagov' or 'search_datasets', leaving some ambiguity about the best context for its application.

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

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

With no annotations provided, the description carries full burden for behavioral disclosure. It states what data is returned (age, race, income demographics) and the data source (American Community Survey), which is helpful. However, it doesn't describe important behavioral traits like whether this is a read-only operation (implied but not stated), potential rate limits, authentication requirements, error conditions, or how county-level data differs from state-level. The description adds some context but 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.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured and appropriately sized. It starts with a clear purpose statement, then provides parameter details in a labeled 'Args' section, and concludes with return value information. Every sentence adds value: the first establishes scope, the parameter explanations are essential given schema gaps, and the return statement clarifies output content. No wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's moderate complexity (2 parameters, US geographic focus), no annotations, and the presence of an output schema (which handles return value documentation), the description is reasonably complete. It covers purpose, parameter semantics, and output content adequately. The main gap is lack of behavioral context like rate limits or error handling, but the output schema reduces the need for detailed return value explanation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds substantial value beyond the input schema, which has 0% description coverage. It explains that 'state' requires a 'Two-letter state code' with examples ('CA', 'TX'), and 'county' is a 'FIPS code (3 digits)' and optional. This provides crucial semantic context that the bare schema lacks. The only minor gap is not clarifying if county codes are state-specific or national.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Get demographic breakdown for a US state or county' with specific data sources (American Community Survey) and demographic categories (age, race, income). It distinguishes from siblings like 'get_population' or 'query_census' by focusing on detailed demographic breakdowns rather than general population counts or census queries. However, it doesn't explicitly contrast with all similar tools like 'get_housing_stats' which might overlap in socioeconomic data.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage context through the parameter descriptions (US state/county focus) and return data specification, suggesting it's for detailed demographic analysis rather than broader geographic or non-US queries. However, it lacks explicit guidance on when to use this tool versus alternatives like 'get_population' for basic counts or 'query_census' for raw census data, and doesn't 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.

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 covers purpose, prerequisites, parameters, and return concept, though it could benefit from more behavioral context like rate limits or error scenarios. The output schema reduces the need to detail return values, keeping it appropriately scoped.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description fully compensates by providing clear parameter documentation in the Args section. It explains both parameters (city and country_code) with examples and indicates country_code is optional, adding essential meaning beyond the bare schema. This is exactly what's needed when schema coverage is low.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific action ('Get current weather'), resource ('for any city worldwide'), and scope ('worldwide'), distinguishing it from siblings like get_weather_forecast (future weather) and get_weather_alerts (alerts). It uses precise language that immediately communicates 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.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implicitly indicates when to use this tool (for US weather forecasts via coordinates) but doesn't explicitly state when not to use it or name alternatives. It doesn't provide guidance on prerequisites or comparisons with similar tools like 'get_global_weather' or 'query_noaa'.

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

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

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions 'raw query' and 'raw JSON response', which implies direct API interaction, but doesn't disclose important behavioral traits like rate limits, authentication requirements, error handling, or whether this is a read-only operation. The description provides minimal behavioral context beyond the basic operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is perfectly structured and front-loaded with the core purpose, followed by organized parameter documentation and return value clarification. Every sentence earns its place, with no wasted words. The Args/Returns formatting makes it easy to scan while maintaining complete information density.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 4-parameter tool with no annotations and no output schema, the description provides adequate parameter documentation but lacks important contextual information. It doesn't explain the nature of the 'raw JSON response' structure, doesn't mention rate limits or authentication, and provides no guidance on error scenarios. While the parameter coverage is excellent, other contextual gaps remain.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description fully compensates by providing clear semantic explanations for all 4 parameters. Each parameter gets specific examples and context: dataset paths like 'acs/acs5', variable codes as a list, geography specifications with examples, and year with default value. This adds substantial meaning beyond the bare schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific action ('Make a raw query') and target resource ('Census API'), distinguishing it from sibling tools that query different data sources like NASA, NOAA, or WorldBank. It provides a precise verb+resource combination that leaves no ambiguity about what this tool does.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. While it's clear this is for Census data, there's no mention of when to choose it over other demographic tools like 'get_demographics' or 'get_population', nor does it specify prerequisites or constraints for effective use.

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

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool returns 'Raw JSON response from Data.gov API,' which hints at the output format, but fails to cover critical aspects like authentication requirements, rate limits, error handling, or whether it's a read-only or mutating operation. For a raw API query tool, 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.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured and front-loaded, with the core purpose stated first, followed by clear sections for 'Args' and 'Returns.' Each sentence earns its place by providing essential information without redundancy, making it efficient and easy to parse.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (raw API queries with 2 parameters), lack of annotations, and no output schema, the description is incomplete. It covers basic purpose and parameters but omits behavioral details like authentication, error handling, and usage context. For a tool that interacts with an external API, this leaves significant gaps in understanding for an AI agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description coverage is 0%, so the description must compensate. It adds value by explaining that 'action' is a 'CKAN action' with examples (e.g., 'package_search'), and 'params' are 'Query parameters for the action.' However, it doesn't detail common actions or parameter structures beyond this, leaving gaps in understanding. This partial compensation justifies a baseline score of 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Make a raw query to the Data.gov CKAN API.' It specifies the verb ('query') and resource ('Data.gov CKAN API'), distinguishing it from siblings like 'search_datasets' or 'get_dataset_info' which likely provide higher-level abstractions. However, it doesn't explicitly contrast with these siblings, keeping it at a 4 rather than a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention scenarios where a raw query is preferred over more specific sibling tools (e.g., 'search_datasets' for dataset searches), nor does it outline prerequisites or exclusions. This lack of contextual direction leaves the agent with minimal usage cues.

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

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

With no annotations provided, the description carries full burden but offers minimal behavioral context. It mentions 'raw query' and 'raw JSON response' but doesn't disclose authentication requirements, rate limits, error handling, or whether this is a read-only operation versus a mutation. The description doesn't contradict annotations since none exist.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is appropriately brief with a clear purpose statement followed by Args and Returns sections. However, the Args section could be more informative given the low schema coverage, and the structure is functional but not optimally front-loaded with critical usage context.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 2 parameters, 0% schema coverage, no annotations, and no output schema, the description is insufficient. It lacks details on authentication, error cases, response structure beyond 'raw JSON', and doesn't compensate for the missing parameter documentation, making it incomplete for reliable agent use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate but provides only basic examples ('/datasets', '/catalogues') without explaining parameter formats, constraints, or semantics. The 'params' field is particularly underspecified as 'Query parameters' with no guidance on structure or valid values.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Make a raw query') and target resource ('EU Open Data Portal API'), distinguishing it from siblings like query_census or query_nasa. However, it doesn't explicitly differentiate from query_datagov or query_worldbank which might have similar raw query patterns.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?
