Server Quality Checklist

58%
Profile completionA complete profile improves this server's visibility in search results.
  • Latest release: v0.1.0

  • Disambiguation4/5

    Tools are grouped by prefixes (bing_, analytics_, seo_, etc.) which helps distinguish them. However, there are aliases like bing_get_top_pages and bing_analytics_page that are identical, and overlapping concepts like seo_low_ctr_opportunities and seo_quick_wins could cause confusion.

    Naming Consistency4/5

    The dominant pattern is prefix_verb_noun, e.g., sites_list, analytics_top_pages. Some tools break the pattern: get_started, diagnostics, util_star_repo lack prefixes, and aliases use 'get' instead of 'list' or 'analyze'.

    Tool Count3/5

    With 104 tools, this is far above the typical range. While it aims to be a comprehensive SEO toolkit covering multiple platforms and domains, the sheer number can overwhelm agents and increase selection complexity.

    Completeness4/5

    The tool surface covers most SEO tasks: site management, analytics, search performance, indexing, page analysis, and recommendations for both Google and Bing. Minor gaps exist, such as lack of Google keyword research tools and limited backlink analysis (only Bing).

  • Average 3.2/5 across 100 of 104 tools scored. Lowest: 2.5/5.

To manually sync the server, click the "Sync Server" button in the MCP server admin interface.

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?

    No annotations are provided, so the description bears full responsibility for behavioral disclosure. It only says 'Get information', failing to mention read-only nature, authentication requirements, or the format of the return value. This is insufficient for an agent to predict the tool's side effects.

    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 short sentence, but it is under-specified. It could be improved by adding key details without sacrificing brevity. Currently it is concise but not effective.

    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?

    The tool has one parameter and no output schema. The description does not explain what the returned information includes. Given the simple nature, a minimal explanation is expected but missing, making it incomplete for an agent to correctly interpret the response.

    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% (siteUrl with a description). The description adds no additional parameter semantics beyond what the schema provides. Baseline 3 is appropriate.

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

    Purpose3/5

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

    The description states 'Get information about a specific site', which indicates a verb+resource but is very generic. It does not specify what type of information (metadata, content, settings) and does not distinguish from sibling tools like sitemaps_get or sites_list.

    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 sites_list or sitemaps_get. The description lacks any context on prerequisites or scenarios where this tool is preferred.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries the full burden. It only mentions 'optional pagination' which is already evident from the schema (startRow, limit). It does not disclose any behavioral traits like rate limits, data freshness, or potential large result sizes.

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

    Conciseness4/5

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

    The description is a single sentence, concise and front-loaded. However, it lacks substance; every word is earned but insufficient information is provided.

    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 the tool (11 parameters, many sibling tools), the description omits critical context such as return format (despite format param), data scope, and use cases. No output schema exists, so description should explain what is returned.

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

    Parameters3/5

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

    The input schema has 100% description coverage, so each parameter is already documented. The tool description adds only 'with optional pagination', which does not enhance understanding beyond the schema. Baseline 3 is appropriate.

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

    Purpose3/5

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

    The description states it queries search analytics data with pagination, but it is vague about the specific data (e.g., metrics) and does not differentiate from many sibling tools like analytics_top_queries or analytics_time_series that have more specific purposes.

    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?

    There is no guidance on when to use this general query tool versus the many specific analytics_* siblings (e.g., top queries, time series). The description fails to provide any context for tool selection.

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

  • Behavior2/5

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

    No annotations exist, so the description must fully disclose behavior. It only states the basic function without detailing side effects, data requirements, or output format. For example, it doesn't mention whether this is a read-only operation or any prerequisites.

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

    Conciseness4/5

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

    The description is a single short sentence with an example, making it concise and easy to scan. However, it could be longer to cover missing context 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?

    For a tool with no output schema and no annotations, the description is insufficient. It lacks usage context, behavioral details, and parameter clarification, leaving the agent to guess important aspects.

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

    Parameters2/5

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

    The description does not add meaning beyond the schema. The schema already documents 'position' and 'engine' with minimal descriptions. The example 'e.g. Top 3, Page 1' refers to the result, not the parameters. The 'engine' parameter description in the schema is just a restatement.

    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 retrieves a ranking bucket for a position, with examples like Top 3 and Page 1. It uses a specific verb (Get) and resource (ranking bucket). However, it does not explicitly distinguish from sibling primitive tools like seo_primitive_is_brand.

    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 (e.g., other primitive tools or SEO analytics tools). There are no when-not or alternative recommendations.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries full burden. It only says 'analyze', implying read-only, but does not explicitly state read-only, required permissions, data scope, or whether results are limited to top N. The description is too sparse to disclose behavioral traits beyond the obvious.

    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, which is concise but lacks structure. It front-loads the purpose but omits important details. While it is not verbose, the brevity results in under-specification for a tool with 5 parameters and many siblings.

    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 5 parameters (3 required), no output schema, and no annotations, the description is incomplete. It does not explain what the output looks like, how conversion is defined, or if it supports filtering. A conversion funnel tool typically needs more context (e.g., steps, attribution).

    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% (all 5 parameters have descriptions), so the schema already provides parameter meanings. The description adds no additional parameter context. Baseline score of 3 is appropriate as it neither adds nor detracts from schema information.

    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 'Analyze top converting pages and events' clearly states the tool's purpose: analyzing conversions by pages and events. It uses a specific verb ('analyze') and resource ('converting pages and events'), distinguishing it from siblings like analytics_top_pages (traffic) and analytics_ecommerce (revenue). However, it could be more precise about 'top converting' (e.g., ranked by conversion count).

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

    Usage Guidelines2/5

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

    The description provides no guidance on when to use this tool versus alternatives. With many sibling tools such as analytics_content_performance and analytics_ecommerce, the agent has no basis to choose this over others. No exclusions or when-not-to-use are mentioned.

    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. It implies a read-only operation but doesn't state side effects, data freshness, or response format. Lacks detail on what 'compare' entails.

    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 single sentence is concise, but it sacrifices valuable information. Could add 1-2 sentences without becoming verbose.

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

    Completeness2/5

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

    Without output schema or annotations, the description should explain what the comparison produces (e.g., delta, percentage). Sibling tools are numerous, so more context is needed to distinguish this tool's specific output.

    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% with good parameter descriptions. However, the tool description adds no extra context about how parameters relate to 'performance' or the nature of the comparison.

    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 the action (compare) and resource (performance in Bing). It distinguishes from non-Bing siblings, but could be more specific about which performance metrics (e.g., clicks, impressions) are compared.

    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 bing_analytics_time_series or analytics_compare_periods. No mention of prerequisites or excluded scenarios.

    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 must fully convey behavioral traits. It only states 'identify the likely cause', which is vague and does not reveal whether the tool performs read-only analysis, requires authentication, or has any side effects.

    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 concise phrase with no waste, but it lacks structure and detail. Every word earns its place, but it could benefit from a brief explanation of the methodology or output.

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

    Completeness2/5

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

    Given no output schema and only three parameters, the description is incomplete. It does not specify what the output looks like (e.g., a list of causes, confidence scores) or how the algorithm works, which is insufficient for effective tool selection among many siblings.

    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?

    All three parameters are described in the schema (100% coverage), so the description does not need to add much. However, it adds no additional meaning beyond the schema, such as explaining how 'days' or 'threshold' influence the analysis.

    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 uses a specific verb ('identify') and resource ('cause of a Bing traffic drop'), making its purpose clear. However, it does not differentiate from the sibling tool 'analytics_drop_attribution', which likely serves a similar function for Google Analytics.

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

    Usage Guidelines2/5

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

    No guidance is provided on when to use this tool versus alternatives like 'analytics_drop_attribution' or other analytics tools. There are no notes on prerequisites, exclusions, or typical scenarios.

    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 only states 'Advanced time series analysis' without indicating whether the tool is read-only, requires authentication, has rate limits, or any other behavioral traits. This is insufficient for safe invocation.

    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, which is concise but at the cost of informativeness. It front-loads 'Advanced' but does not elaborate on what makes it advanced or how it works. It could be restructured to include more details without becoming verbose.

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

    Completeness2/5

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

    Given 4 parameters, no output schema, and the complexity of time series analysis, the description is incomplete. It does not mention return format, pagination, or how results are structured. Compared to siblings like bing_analytics_trends, which likely have more descriptive documentation, this falls short.

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

    Parameters3/5

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

    The input schema has 100% coverage with descriptions for all parameters, so baseline is 3. The description adds no additional meaning beyond the schema, such as explaining how 'advanced' analysis differs or using parameters effectively. No extra value is provided.

    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 'Advanced time series analysis for Bing performance data' indicates a specific verb (analysis) and resource (Bing performance data). It distinguishes itself from siblings like analytics_time_series (likely for Google) by the 'Bing' prefix, though 'analysis' is somewhat vague regarding actual 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?

    The description provides no guidance on when to use this tool versus alternatives such as bing_analytics_trends or bing_analytics_compare_periods. No when-to-use or when-not-to-use information is given, leaving the agent without context for selection.

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

  • Behavior2/5

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

    No annotations are provided, so the description must disclose behavior. It only states 'check if two pages are competing' without indicating whether it is read-only, required permissions, output format, or side effects. Minimal behavioral context.

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

    Conciseness5/5

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

    Description is a single, clear sentence with no wasted words. Earns its place efficiently.

    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?

    With 8 parameters, no output schema, and no annotations, the description is insufficient. It omits how the metrics are used, what the result looks like, and any edge cases or assumptions. A more detailed description is needed for completeness.

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

    Parameters2/5

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

    Schema description coverage is only 25% (query and engine have descriptions). The description does not explain the remaining six parameters (positions, impressions, clicks) or how they contribute to the cannibalization check. Parameter names are somewhat self-explanatory, but the description should add more 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 checks if two pages compete for the same query using metrics. The 'primitive:' prefix and naming distinguish it from higher-level siblings like 'seo_cannibalization', though explicit differentiation is absent.

    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 primitive tool versus alternatives such as 'seo_cannibalization' or other analytics tools. The description does not specify context or prerequisites.

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

  • Behavior2/5

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

    Without annotations, the description carries full behavioral transparency burden. It indicates a write operation ('authorize') but does not disclose side effects, reversibility, permission requirements, or behavior on duplicates.

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

    Conciseness4/5

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

    The description is a single sentence with no wasted words. It includes useful parenthetical context ('Account Boundary'). While minimal, it is appropriately concise for a tool with few parameters.

    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?

    The description is too brief for a mutation tool with no output schema or annotations. It lacks information on success indicators, error conditions, or post-requisites, leaving the agent with incomplete guidance.

    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% with clear descriptions for both parameters. The tool description adds no extra meaning beyond the schema; it does not clarify formats, validation rules, or relationships between parameters.

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

    Purpose4/5

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

    The description clearly states the action ('authorize') and the resource ('specific site or domain for an account'). The parenthetical 'Account Boundary' hints at scope but does not explicitly differentiate from sibling tools like 'sites_add', which may add a site to a different context.

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

    Usage Guidelines2/5

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

    No guidance is provided on when to use this tool versus alternatives such as 'sites_add' or 'accounts_list'. There is no mention of prerequisites, conditions, or when not to use it.

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

  • Behavior2/5

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

    With no annotations, the description bears full responsibility for behavioral traits. It only states 'performance breakdown' without indicating read-only nature, data freshness, pagination, or that it returns metrics like clicks/impressions (implied by schema but not described).

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

    Conciseness4/5

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

    The description is a single, clear sentence without filler. However, it could include the siteUrl context without becoming verbose. Still, it is appropriately sized.

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

    Completeness2/5

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

    Given no output schema, the description should outline what the response looks like (e.g., list of countries with metrics). It does not. The tool has 4 parameters, and while schema covers them, the description lacks completeness regarding output and usage context.

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

    Parameters3/5

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

    Schema coverage is 100%, with each parameter having a clear description in the schema. The description adds no additional parameter insight beyond what the schema provides, so a 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 tool returns a performance breakdown by country for a specified period, which distinguishes it from siblings like analytics_top_pages or analytics_traffic_sources. However, it does not explicitly mention that it operates per site (siteUrl required), which is inferred from the schema.

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

    Usage Guidelines2/5

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

    No guidance is given on when to use this tool versus other analytics tools (e.g., analytics_top_pages, analytics_traffic_sources). The description simply states functionality without context on usage scenarios or alternatives.

    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 must convey behavioral traits. It states the tool 'gets' data, implying a read operation, but does not confirm safety, disclose side effects (none expected), required authorizations, or rate limits. The tool name and context suggest it's analytic and read-only, but the description leaves uncertainty.

    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, clear sentence that directly states the tool's purpose. It is front-loaded and contains no redundant or extraneous information. It efficiently communicates the core function.

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

    Completeness2/5

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

    Given the lack of an output schema, the description should hint at the structure of returned data (e.g., list of appearance types with metrics) but does not. With 4 parameters, it covers the basics but omits context like default values for 'days' and 'limit' (though schema provides defaults) or the meaning of 'appearance type'. The description is too sparse to fully prepare an agent for invocation.

    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 tool description itself does not add any parameter-specific details beyond the schema. For example, it does not explain acceptable formats for 'siteUrl' or the effect of 'sortBy'. The schema descriptions are adequate but the tool description misses the chance to clarify parameter usage.

    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 accurately states that the tool retrieves performance data grouped by search appearance type over a set period. It uses 'get performance breakdown', a clear verb-noun pair, and specifies the grouping dimension. Among many sibling analytics tools, it focuses on a distinct dimension (search appearance), though it doesn't explicitly differentiate itself from others like 'analytics_page_performance'.

    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 usage guidelines are provided. The description does not indicate when to use this tool over alternatives like 'analytics_top_queries' or 'analytics_by_country'. There is no mention of prerequisites (e.g., site must be verified) or when not to use it. Given the large sibling set, this omission hinders correct selection.

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

  • Behavior2/5

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

    The description does not explain how trends are determined (e.g., comparing periods, statistical methods) or any behavioral traits like data freshness or required history. With no annotations, this is a significant gap.

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

    Conciseness5/5

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

    The description is a single sentence with no wasted words. It is appropriately front-loaded and efficient.

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

    Completeness2/5

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

    Given no output schema and moderate complexity, the description lacks details on return value structure, trend calculation, and how parameters interact, leaving the agent underinformed.

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

    Parameters3/5

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

    Schema description coverage is 100%, so all parameters are already documented. The tool description adds no further meaning beyond the schema, meeting the baseline expectation.

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

    Purpose4/5

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

    The description clearly states the tool detects traffic trends (rising/declining) for queries or pages, making the purpose specific and distinguishable from siblings like analytics_time_series. However, it could be more precise about the comparison aspect.

    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 such as analytics_time_series, analytics_compare_periods, or analytics_anomalies. The agent must infer usage 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 provided, so the description must carry the full burden. It only states the action without disclosing behavioral traits such as whether the tool is read-only, what constitutes an anomaly, or any side effects. The agent is left uninformed about the tool's safety profile.

    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, well-structured sentence that communicates the core purpose efficiently. No redundant words or phrases.

    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?

    The description is minimal and does not explain return values, output format, or expected behavior. Since there is no output schema and no annotations, the agent lacks critical context needed to interpret the tool's results 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?

    The input schema already provides descriptive text for all three parameters (siteUrl, days, threshold), achieving 100% coverage. The description adds no additional meaning beyond the schema, so a baseline score of 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 verb 'Detect' and resource 'performance anomalies in Bing traffic'. It is specific and understandable, but does not differentiate from the sibling tool 'analytics_anomalies' which has a similar purpose based on name.

    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. The description lacks any context about prerequisites, typical scenarios, or when not to use it. Given many sibling analytics tools, this omission increases risk of incorrect tool selection.

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

  • Behavior2/5

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

    With no annotations, the description carries the full burden but only states a simple action. No disclosure of authentication needs, read-only nature, pagination, or output format. Critical behavioral details 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?

    A single sentence that is efficient and front-loaded with the core action. However, it could include structured breaks for usage notes or parameter details without harm.

    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 three parameters, no output schema, and many sibling tools, the description is too minimal. It doesn't explain what 'performance stats' includes, how dates interact, or how this tool differs from similar ones. Incomplete for informed 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 covers all three parameters with descriptions (siteUrl, startDate, endDate format). The description adds no additional meaning beyond the schema, so baseline score of 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 'get' and resource 'page performance stats' from Bing Webmaster Tools (Top Pages). It is specific but doesn't differentiate from siblings like 'bing_analytics_page_query' or 'bing_get_top_pages', leaving some ambiguity about exact scope.

    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 such as 'bing_analytics_page_query', 'bing_get_top_pages', or other analytics tools. The description provides no context for selection.

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

  • Behavior2/5

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

    With no annotations, the description must disclose behavioral traits. It only states it gets stats, but doesn't confirm it's read-only, doesn't mention authentication, rate limits, pagination, or the nature of the response. The agent lacks critical behavioral context beyond the action.

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

    Conciseness4/5

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

    The description is a single concise sentence that conveys the core purpose. It is front-loaded and efficient, though it lacks structure (e.g., no bullet points or separate sections). The null title means the description bears all the weight.

    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 5 parameters, no output schema, and many sibling tools, the description is incomplete. It doesn't explain what 'query performance stats' includes, how results are formatted, or how to interpret the output. It fails to disambiguate from similar tools in the sibling list.

    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 new meaning to the parameters beyond what the schema already provides. The parenthetical '(Top Queries)' is vague and does not clarify which parameter affects that concept.

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

    Purpose4/5

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

    The description clearly states the action ('Get') and resource ('query performance stats') from a specific source (Bing Webmaster Tools). However, it does not differentiate it from siblings like 'bing_get_top_queries' which also deals with top queries. The parenthetical '(Top Queries)' provides some context but could be confused with other tools.

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

    Usage Guidelines2/5

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

    No usage guidelines are provided. The description does not specify when to use this tool over alternatives such as 'bing_analytics_compare_periods' or 'bing_get_top_queries'. There is no mention of prerequisites, context, or when not to use it.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries full burden. It states a detection function but does not disclose if the tool is read-only, requires authentication, or has any side effects. The minimal description lacks transparency about behavior.

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

    Conciseness4/5

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

    The description is a single concise sentence that efficiently conveys the core purpose. No wasted words, though it could benefit from structured bullets for additional details.

    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 full schema coverage, the description fails to explain the output format, how trends are calculated, or how to interpret results. With no output schema, the description should provide completeness, which it lacks.

    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 does not need to add parameter details. However, it adds no additional context (e.g., how 'threshold' relates to trend detection). Baseline of 3 is appropriate as schema covers parameters but description adds no value beyond.

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

    Purpose4/5

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

    The description clearly states the tool's verb ('Detect') and resource ('rising or declining trends in Bing query performance'). It distinguishes from the generic sibling 'analytics_trends' by specifying 'Bing', but could be more precise about what constitutes a trend (e.g., over what period?).

    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 'analytics_trends' or other Bing analytics tools. There is no mention of prerequisites, context, 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 present, so the description bears full responsibility for behavioral disclosure. It only states the action without mentioning whether the operation is read-only, requires authentication, has rate limits, or what the output format is. This is insufficient for an agent to understand side effects or constraints.

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

    Conciseness4/5

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

    The description is a single sentence with no superfluous words. It is front-loaded with the core action. However, it may be overly terse, missing necessary details without being verbose.

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

    Completeness2/5

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

    Given the simplicity of the tool (one parameter, no output schema, no annotations), the description should provide sufficient context. It does not specify expected URL format, prerequisites (e.g., site must be added earlier), or how results are returned, leaving gaps for an AI agent.

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

    Parameters3/5

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

    There is only one parameter (siteUrl), and the schema already describes it as 'The URL of the site'. The description adds no additional semantic meaning or format guidance, so it meets the baseline for 100% schema coverage.

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

    Purpose4/5

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

    The description uses a specific verb ('Get') and resource ('crawl issues') and indicates the source ('Bing Webmaster Tools'). While it doesn't explicitly distinguish from sibling tools like bing_crawl_stats, the term 'crawl issues' is reasonably distinct from 'crawl stats', making the purpose clear.

    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. The description lacks any context about prerequisites, typical use cases, or criteria for selecting this tool over siblings such as bing_crawl_stats or bing_sites_health.

    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 the burden of behavioral disclosure. It merely labels it as an alias and states the action, but does not reveal behavioral traits such as read-only nature, return format, or limitations.

    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 sentences, including an alias reference that helps avoid duplication. However, it could be improved by adding more context without significant length.

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

    Completeness2/5

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

    Given no output schema, the description should explain return values or additional behavior, but it does not. The tool is simple, but key completeness is missing for effective use.

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

    Parameters3/5

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

    Schema coverage is 100%, and the description adds no additional meaning beyond the schema's description of siteUrl. 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 states it is an alias for bing_analytics_page and specifies the action 'Get top pages for a site,' clearly indicating what the tool does. However, it does not explain why the alias exists or differentiate it from the original tool, which is essentially the same.

    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 alias versus the original bing_analytics_page or other sibling tools. The description gives no context for selection.

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

  • Behavior2/5

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

    No behavioral traits beyond the tool's purpose are disclosed. The description does not mention whether it is read-only, performance implications, or any constraints. Annotations are absent, so the description carries the full burden but fails to add relevant context.

    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 short (two sentences) and front-loaded with the core action. The alias information is necessary context. No unnecessary words.

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

    Completeness2/5

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

    For a tool that returns 'top queries,' the description lacks details about the output format, ordering, or limitations. Given no output schema, more context is expected to fully define the tool's behavior.

    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% with descriptions for all three parameters. The description does not add additional meaning beyond what the schema already provides, so baseline score of 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 it gets top queries for a site, with a specific verb and resource. However, it also mentions being an alias for bing_analytics_query, which introduces some ambiguity about its exact scope compared to the general tool.

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

    Usage Guidelines2/5

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

    No guidance is provided on when to use this tool versus its sibling bing_analytics_query or other analytics tools. The alias hint is present but not sufficient for decision-making.

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

  • Behavior2/5

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

    With no annotations provided, the description carries the full burden of disclosing behavioral traits. It indicates a read operation ('Get') but does not mention authentication requirements, rate limits, what 'historical' means in terms of time range, or the format of the returned stats. The description is insufficiently transparent.

    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, consisting of a single sentence. While it is not verbose, it could include more context without sacrificing conciseness. It earns a score of 4 for being appropriately sized and front-loaded.

    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 3 parameters, no output schema, and no annotations, the description is incomplete. It does not explain what the returned historical stats include, any limitations (e.g., date ranges), or how the output structure looks. More context is needed for the agent to use it effectively.

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

    Parameters3/5

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

    Schema description coverage is 100%, so the input schema already documents each parameter (q, country, language) adequately. The tool description adds no additional meaning beyond the schema. Per guidelines, baseline is 3 when coverage is high, making this score 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 'Get' and the resource 'historical stats for a keyword in Bing'. It is specific enough to convey the tool's basic function, but it does not differentiate from sibling tools like bing_rank_traffic_stats or bing_related_keywords, which also deal with keyword stats.

    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 offers no guidance on when to use this tool versus alternatives such as bing_rank_traffic_stats or bing_related_keywords. There is no mention of context, prerequisites, or exclusions, leaving the agent without decision support.

    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 disclose behavior. It only states the tool 'identifies' queries, implying a read-only operation, but does not confirm safety, side effects, or output details. The lack of behavioral context beyond the basic function is insufficient for safe agent invocation.

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

    Conciseness4/5

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

    The description is a single, clear sentence with no wasted words. It is front-loaded with the core function. However, it may be too brief given the lack of annotations and output schema.

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

    Completeness3/5

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

    Given no output schema and no annotations, the description is minimal. It covers the core purpose but omits return format, pagination, or data scope. For a simple list tool, it is adequate but could be more complete.

    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% with both parameters described in the schema. The description does not add additional meaning beyond what the schema provides. Baseline score of 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 tool identifies 'high-ranking Bing queries with lower than expected CTR'. The verb 'Identify' and the resource 'Bing queries with low CTR' are specific. It distinguishes from sibling tools like 'seo_low_ctr_opportunities' by specifying 'Bing' in the name and description.

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

    Usage Guidelines2/5

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

    The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, context, or exclusions. With many sibling analytics and SEO tools, users lack direction on selecting 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?

    No annotations are provided, and the description does not disclose important behavioral traits such as permissions needed, side effects, or return format. For a tool with zero annotations, this is a significant gap.

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

    Conciseness4/5

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

    A single, well-formed sentence. No wasted words, but could benefit from additional succinct context.

    Purpose4/5

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

    The description clearly states it finds 'high-potential low-hanging fruit keywords' in Bing, specifying a clear verb and resource. However, it does not differentiate from sibling tools like 'bing_low_ctr_opportunities' or 'seo_low_hanging_fruit', which have similar purposes.

    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, no prerequisites, and no exclusion criteria. The description lacks any usage context beyond the basic purpose.

    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 'Get historical rank and traffic statistics' without disclosing data range, read-only nature, rate limits, or authorization requirements. Minimal behavioral context.

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

    Conciseness4/5

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

    Single sentence, no wordiness. However, could be slightly more informative 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?

    No output schema, no annotations. Description omits return format, historical period, or any context about the statistics. Incomplete for an agent to fully understand tool behavior.

    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?

    Only one parameter 'siteUrl' with description in schema covering 100%. Tool description does not add meaning beyond 'URL of the site', 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 'Get historical rank and traffic statistics for a site', specifying the verb and resource. It distinguishes from siblings like bing_keywords_stats (keywords) and bing_get_top_pages (pages) by focusing on rank and traffic.

    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, no prerequisites or exclusions. Given many sibling tools with overlapping functionality, this is a significant gap.

    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 behavioral burden but only states the purpose, omitting details on response format, definition of significant traffic loss, pagination, or authentication requirements.

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

    Conciseness4/5

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

    The description is a single concise sentence of 11 words, efficiently conveying the core purpose, though it could be slightly expanded to include critical behavioral details 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?

    For a tool with no output schema and no annotations, the description lacks essential context such as how 'significant' is defined, what the previous period is, and what the output looks like, making it incomplete for agent usage.

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

    Parameters3/5

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

    Schema description coverage is 100% with clear parameter descriptions, so baseline is 3. The tool description adds no additional meaning beyond what the schema already provides.

    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 specific verb 'identify' and resource 'queries that lost significant traffic on Bing compared to the previous period', making the purpose clear and distinguishing it from general seo_lost_queries and other Bing analytics tools.

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

    Usage Guidelines2/5

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

    The description only implies when to use (when needing lost queries on Bing) but offers no explicit guidance on when not to use or how it compares to similar siblings like bing_analytics_drop_attribution or seo_lost_queries.

    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. It only says 'submit' but fails to disclose mutation behavior, success/failure modes, rate limits, or authentication requirements.

    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 (one sentence) and front-loaded with the purpose. However, it may be too brief and could benefit from additional context without sacrificing efficiency.

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

    Completeness3/5

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

    For a simple tool with two parameters and no output schema, the description is adequate but lacks context about prerequisites, expected outcomes, and error handling. Agent may need more information 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 description coverage is 100%, so the schema already explains the two parameters. The description adds no additional meaning beyond the schema's documentation.

    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 'submit' and resource 'sitemap' to Bing Webmaster Tools, making the purpose unambiguous. However, it does not differentiate from sibling tools like sitemaps_submit which might target a different search engine.

    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 (e.g., bing_sitemaps_list, bing_sitemaps_delete, or generic sitemaps_submit). Prerequisites like site ownership verification are not mentioned.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries full burden. It only mentions 'Google only' but omits critical behavioral traits like required permissions, confirmation of action, error modes, or API limits.

    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 one short sentence with no wasted words. However, it could be slightly expanded to include a usage hint 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 no output schema, the description should inform about return values, but it doesn't. Also lacks context on site verification requirements or what happens after notification. The description is too minimal for a complete understanding.

    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 does not add meaning beyond the schema; it only paraphrases the parameter names. No additional context like URL format or validation rules.

    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 notifies Google of URL removal, with a concrete example (expired job posting). While the verb 'remove' distinguishes it from the sibling 'indexing_submit_url', it could be more explicit about the opposite direction.

    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 indexing_submit_url or indexing_batch_submit. The description lacks context on prerequisites or typical scenarios.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries full burden. It lacks details on read-only nature, authentication needs, rate limits, or any side effects. The description is too brief to convey 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.

    Conciseness4/5

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

    The description is a single sentence of 10 words, front-loaded with the key action. It is concise with no wasted words, though a bit too terse given the tool's complexity.

    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?

    The tool has 9 parameters and no output schema. The description does not explain the return value, how prioritization works, or the relationship between inputs. It feels incomplete for a multi-source combining 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 coverage is 100% with individual parameter descriptions. The description adds context by naming the data sources but does not add extra semantic meaning beyond the schema. 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 states a clear purpose: prioritize SEO tasks using signals from GSC, GA4, and Bing. However, it does not explicitly differentiate from many sibling SEO tools with similar objectives.

    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, prerequisites, or when not to use it. With many sibling tools, this omission limits effective selection.

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

  • Behavior2/5

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

    With no annotations available, the description carries the full burden of behavioral disclosure. It states the tool performs analysis but does not mention that it is a read-only operation, potential rate limits, or that it fetches data from an external API.

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

    Conciseness4/5

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

    The description is a single concise sentence that effectively communicates the tool's purpose. It is well-structured and no extraneous 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?

    Given the tool has only two simple parameters and no output schema, the description is minimally adequate. It explains what the tool returns (scores across categories) but lacks details on the output format or how to interpret results.

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

    Parameters3/5

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

    The input schema covers both parameters (url and strategy) with descriptions, so the schema provides sufficient meaning. The description does not add extra semantics 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 clearly states that the tool runs PageSpeed Insights analysis and lists the categories of scores (performance, accessibility, best practices, SEO). It distinguishes the tool from related tools like pagespeed_core_web_vitals by focusing on a broader set of scores. However, it could be more specific about the output being Lighthouse scores.

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

    Usage Guidelines2/5

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

    No guidance is provided on when to use this tool versus alternatives like pagespeed_core_web_vitals. There is no mention of prerequisites or contexts where it should not be used.

    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 behavioral disclosure. It mentions using a regex but does not disclose potential side effects, error handling (e.g., invalid regex), authentication requirements, or the nature of the output. This is insufficient for a tool that processes data.

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

    Conciseness4/5

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

    The description is a single, concise sentence that efficiently communicates the core purpose. It is front-loaded and avoids redundancy. However, it could be slightly expanded to include usage context 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 tool has four parameters, no output schema, and several sibling tools, the description lacks completeness. It does not explain what 'performance split' entails, what the output format is, or how results are organized. Users would need additional documentation to use the tool effectively.

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

    Parameters3/5

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

    Schema description coverage is 100%, meeting the baseline for this dimension. The description adds no extra meaning beyond the parameter descriptions; it merely reiterates the use of a regex, which is already detailed in the 'brandRegex' parameter. No additional semantic value is provided.

    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 analyzes performance split between Brand and Non-Brand queries using a regex. It specifies the action, resource, and method, making the purpose clear. However, it does not explicitly differentiate from similar sibling tools like 'brand_analysis', so not a 5.

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

    Usage Guidelines2/5

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

    The description provides no guidance on when to use this tool versus alternatives such as 'brand_analysis' or 'seo_primitive_is_brand'. There is no mention of prerequisites, limitations, or exclusions, leaving the agent without decision context.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries the full burden of disclosing behavior. The description only states the function without explaining how it works (e.g., it requires Google Search Console access, returns a list of issues, defines cannibalization based on ranking overlaps, or is read-only). For a tool with no annotation safeguards, this is insufficient.

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

    Conciseness4/5

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

    The description is a single sentence, direct and without unnecessary words. However, it is only 10 words and could be more structured with additional context. It earns a 4 because it is concise but not overly, and the front-loading is good.

    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?

    With no output schema, the description should explain the return value (e.g., list of cannibalization issues with pages and queries). It does not. Also, given 5 parameters and no behavioral details, the description is incomplete for an agent to use effectively. For a tool with moderate complexity, this is insufficient.

    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%, meaning all parameters have descriptions. The description adds minimal extra meaning beyond the schema—it confirms the concept of cannibalization but doesn't clarify parameter usage or constraints. Baseline 3 is appropriate as the schema already documents parameters adequately.

    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 detects keyword cannibalization, which is multiple pages competing for the same query. It uses a specific verb 'detect' and resource 'keyword cannibalization'. However, it does not explicitly differentiate from siblings like 'seo_primitive_is_cannibalized' (which checks a specific page) or 'bing_seo_cannibalization' (for Bing), so it gets a 4 instead of a 5.

    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 (e.g., for a specific page check use 'seo_primitive_is_cannibalized', for Bing use 'bing_seo_cannibalization'). It does not mention prerequisites, limitations, or when not to use it. This is a significant gap.

    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 states the tool 'finds' keywords, implying a read operation but not confirming side effects, authentication needs, or data sensitivity. The description does not disclose behavioral traits beyond the basic purpose.

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

    Conciseness4/5

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

    The description is a single, front-loaded sentence that efficiently states the purpose. It is concise, though it could include more detail without becoming verbose.

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

    Completeness2/5

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

    Given the tool has 5 parameters, no output schema, and no annotations, the description is too brief. It lacks information about return format, performance implications, or important notes about the data source, leaving the agent underinformed.

    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 no additional meaning to parameters; the schema already describes defaults and enumerations adequately.

    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 finds keywords with high impressions and low rankings, which is a specific verb-resource combination. It is distinct from siblings like 'seo_low_ctr_opportunities' and 'seo_striking_distance', though it does not explicitly differentiate.

    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. The description implies a scenario (finding growth keywords) but provides no exclusions or context about when to use other tools.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries the full burden. It does not disclose whether the tool is read-only, requires authentication, or has any side effects. The agent is left to infer that it is a query tool, but no explicit behavioral traits are given.

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

    Conciseness5/5

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

    The description is a single sentence that is concise and front-loaded with the action verb. It contains exactly the necessary information without extraneous text.

    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 having 5 parameters, no output schema, and no annotations, the description is minimal. It does not explain what the tool returns, how it determines 'could be pushed', or the effect of default parameter values. More context would be beneficial for a tool with multiple filters.

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

    Parameters3/5

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

    The input schema has 100% description coverage for all parameters, so the description adds no additional meaning beyond the schema. 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.

    Purpose4/5

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

    The description clearly states the tool's purpose: finding pages with queries ranking on page 2 (positions 11-20) that could be pushed to page 1. However, it does not differentiate from siblings like seo_low_hanging_fruit or seo_striking_distance, which may have similar purposes.

    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 alternative SEO tools (e.g., seo_low_hanging_fruit, seo_striking_distance). There is no mention of prerequisites or when not to use it.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries full burden. It only says 'Get details' without disclosing any behavioral traits such as read-only nature, required permissions, or potential side effects. The description is too vague.

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

    Conciseness4/5

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

    The description is a single concise sentence with no extraneous words. It is front-loaded with the core action, but could benefit from slightly more detail without becoming verbose.

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

    Completeness2/5

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

    Given no output schema, the description should explain what 'details' are returned (e.g., status, dates, content). It does not, leaving the agent uncertain about the return value. For a simple get tool, this is a notable gap.

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

    Parameters3/5

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

    Schema description coverage is 100%, so the parameters are already documented. The description adds no additional meaning beyond the schema, meeting the baseline expectation.

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

    Purpose4/5

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

    The description clearly states it retrieves details for a specific sitemap, using the verb 'Get' and specifying 'specific sitemap'. However, it does not differentiate from sibling tools like 'sitemaps_list' or 'sitemaps_submit', which could cause ambiguity.

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

    Usage Guidelines2/5

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

    There is no guidance on when to use this tool versus alternatives. No context about prerequisites, when not to use it, or which scenarios it is suited for.

  • Behavior2/5

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

    No annotations provided. Description lacks disclosure of mutation side effects, authentication needs, or site verification prerequisites. Agent cannot infer safety or constraints.

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

    Conciseness5/5

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

    Single clear sentence with no wasted words. Efficient for a simple tool.

    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?

    No output schema. Description does not mention return value or error cases. Given it's a mutation tool, more behavioral context is needed.

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

    Parameters3/5

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

    Schema covers both parameters with descriptions (siteUrl, engine). Description adds no extra meaning beyond schema. Baseline 3.

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

    Purpose4/5

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

    The description clearly states the verb 'Add' and resource 'site' with specific platforms (Search Console or Bing Webmaster Tools). It distinguishes the tool as multi-engine, but does not explicitly contrast with 'bing_sites_add' sibling.

    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 like 'bing_sites_add'. No context about prerequisites or conditions for adding a site.

  • Behavior2/5

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

    No annotations are provided, so the description carries full burden. It only mentions checking performance trends and status without disclosing behavioral traits such as whether it is read-only, what permissions are needed, or what the output format is.

    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 concise and front-loaded with the action. It uses one sentence effectively with no wasted words.

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

    Completeness2/5

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

    Given the tool's simplicity (2 optional params, no output schema, no annotations), the description is minimal. It does not explain what a health check entails, what kind of results to expect, or how it differs from related tools, leaving gaps for the agent to infer.

    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% with descriptions for both parameters. The description adds no extra meaning beyond the schema, meeting the baseline for high coverage.

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

    Purpose4/5

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

    Description clearly states the tool runs a health check on one or all verified sites, checking performance trends and status. It distinguishes from siblings like 'traffic_health_check' by focusing on site health rather than traffic. However, it could be more precise about what aspects of health are checked (e.g., uptime, speed).

    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 lacks explicit guidance on when to use this tool versus alternatives. It does not mention when not to use it or provide comparisons to similar tools like 'diagnostics' or 'bing_sites_health'.

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

    The description is concise (one line, 12 words) but lacks substance. Every sentence should add value; this sentence is too vague and does not fully earn its place.

    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?

    With no output schema and multiple sibling tools (27 bing_* analytics tools), the description is incomplete. It fails to explain return values, date range handling, or how combined stats work, leaving the agent underinformed.

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

    Parameters3/5

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

    The input schema has 100% description coverage for all three parameters (siteUrl, startDate, endDate). The tool description adds no extra meaning beyond what the schema already provides. 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 identifies the verb 'Get' and the resource 'combined query and page performance stats for a site'. It distinguishes from sibling tools that focus on just page or just query stats, such as bing_analytics_page and bing_analytics_query.

    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 bing_analytics_page_query or other analytics tools. The description does not specify use cases or exclusions.

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

  • Behavior2/5

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

    No annotations exist, so the description must disclose behavioral traits. It only says 'Detect pages', implying a non-destructive read operation, but does not mention return format, side effects, authentication needs, or pagination behavior.

    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 eight-word sentence, very concise. However, it sacrifices necessary details for brevity, making it under-specified for a tool with no output schema.

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

    Completeness2/5

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

    Given the lack of output schema and annotations, the description fails to explain the output format, what constitutes 'cannibalization', or any behavioral details. The tool's complexity is low, but completeness is insufficient for reliable agent usage.

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

    Parameters3/5

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

    The input schema has 100% description coverage for both parameters ('siteUrl' and 'minImpressions'). The description adds no additional parameter semantics beyond the schema, meeting the baseline of 3.

    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 verb 'Detect' and resource 'pages competing for the same query in Bing'. It distinguishes from the sibling 'seo_cannibalization' by specifying the Bing engine, making its scope explicit.

    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 'seo_cannibalization' (presumably for Google) or 'seo_primitive_is_cannibalized'. No when-not or context for selection.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries the full burden. It only states the tool 'Analyze[s] ... performance' without disclosing behavioral traits such as output format, read-only nature, authentication needs, or side effects. This is a significant gap for a tool with 9 parameters.

    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, concise sentence front-loading the purpose. However, it is overly minimal for a tool with 9 parameters and no other documentation. It earns its place but lacks structure (e.g., bullet points) to improve readability or add needed detail.

    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 lack of annotations, output schema, and the complexity of 9 parameters (6 required), the description is incomplete. It does not explain what the analysis returns, how results are presented, or any constraints (e.g., date formats, account prerequisites). The tool needs more context for reliable agent invocation.

    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 each parameter. The description adds no extra meaning beyond the schema; it simply lists the data sources. Baseline of 3 is appropriate as the description does not compensate for any missing schema detail.

    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 analyzes 'Brand vs Non-Brand performance' across three specified data sources (GSC, Bing, GA4), using a specific verb and resource. This distinguishes it from siblings like 'bing_brand_analysis' (Bing-only) and 'seo_brand_vs_nonbrand' (likely SEO-focused).

    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?

    Single sentence, efficient and to the point. No unnecessary words.

    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 simple check tool, but lacks details about return value (e.g., boolean) and how the optional engine parameter affects behavior. Without output schema, more context on output would help.

    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 all parameters with descriptions (100% coverage). Description adds 'based on a regex pattern' but this is redundant with the schema. Does not add new meaning beyond 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?

    Description clearly states the tool checks if a query is a brand query using a regex pattern. It distinguishes itself from the sibling 'seo_brand_vs_nonbrand' by being a primitive check, though it doesn't mention the output format.

    No guidance on when to use this primitive versus alternative brand analysis tools. Does not specify prerequisites or context.

    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 does not disclose side effects, authorization needs, rate limits, or output format. The verb 'generate' suggests a non-destructive operation, but this is 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?

    The description is a single sentence of 9 words, highly concise and front-loaded. Every word adds value.

    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 carry full burden. It only states it gets metrics but does not disclose if it is read-only, requires authentication, has rate limits, or any side effects. The term 'aggregate' is vague.

    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 with no wasted words. Front-loaded with verb and resource, then specifies metrics. Highly 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?

    No output schema, but description partially compensates by listing metrics. However, it does not specify return structure (e.g., single object or array, per page or total). Adequate for a simple summary tool with 3 parameters.

    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?

    Description adds value beyond schema by listing the specific metrics returned (clicks, impressions, CTR, position) and linking 'last N days' to the days parameter. Schema coverage is 100%, so baseline 3, but the extra details raise it to 4.

    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 it retrieves aggregate performance metrics (clicks, impressions, CTR, position) for the last N days, specifying the verb 'Get' and the resource. It distinguishes itself from siblings by focusing on aggregated summary rather than detailed breakdowns, but does not explicitly differentiate.

    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 analytics_query or analytics_time_series. The description lacks context on prerequisites, use cases, or situations where other tools are preferred.

    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?

    The description only states the generic purpose. With no annotations, it fails to disclose behavioral traits such as whether the operation is read-only, any authentication requirements, rate limits, or what 'query performance stats' entails (e.g., metrics included). This leaves the agent without crucial behavioral context.

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

    Conciseness5/5

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

    Completeness2/5

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

    Given the lack of output schema and annotations, and the presence of many sibling tools, the description is too minimal. It does not explain what 'query performance stats' are, how the date parameters affect the results, or how this tool differs from similar ones like bing_analytics_query_page (which might be identical). The agent lacks essential context to use it effectively.

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

    Parameters3/5

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

    The input schema has 100% description coverage, so the baseline is 3. The description adds no additional meaning to the parameters; it simply restates the tool's purpose. For example, it does not explain the relationship between siteUrl and pageUrl or the date range format beyond what schema already provides.

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

    Purpose5/5

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

    The description clearly states the specific action ('Get query performance stats') and the target resource ('for a specific page from Bing Webmaster Tools'). It distinguishes from siblings like bing_analytics_page and bing_analytics_query by combining both page and query dimensions.

    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?

  • 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 states 'returns actions' but does not explicitly confirm whether the tool mutates data or is read-only. No side effects, authentication needs, or rate limits are mentioned, leaving significant uncertainty.

    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 short sentences that front-load the core purpose with a clear verb and resource. Every sentence adds value without redundancy, making it efficient for an AI agent to parse quickly.

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

    Completeness2/5

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

    Given the tool has three parameters, no output schema, and no annotations, the description should provide richer context. It explains what it does but omits return format, prerequisites, or when to use it among many sibling tools, leaving the agent underinformed.

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

    Parameters3/5

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

    The input schema covers 100% of parameters with descriptions (siteUrl, days, maxRecommendations). The tool description adds no additional explanation for these parameters beyond what the schema already provides, so the baseline score of 3 applies.

    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 prioritized SEO recommendations by cross-referencing quick wins, content gaps, and cannibalization, and explicitly lists return types (update/create/consolidate actions). This distinguishes it from generic recommendations tools like sibling seo_recommendations by specifying the cross-referencing approach.

    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, such as prerequisites, exclusions, or scenarios where it is not appropriate. The agent has no context to decide between this and similar SEO tools like seo_quick_wins or seo_cannibalization.

    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 fully convey behavioral traits. It fails to disclose that this is a read-only operation, lacks mention of authorization requirements or rate limits, and does not describe the response format or error handling. The minimal description leaves the agent without important behavioral context.

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

    Conciseness5/5

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

    The description is a single, well-structured sentence that conveys the core purpose without unnecessary words. It is front-loaded and efficient.

    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 absence of annotations and output schema, the description is too brief. It does not explain the return status (e.g., notification type, timestamp), prerequisites (URL must have been submitted), or how to interpret the results. For a status-checking tool, this is insufficiently complete.

    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?

    With 100% schema description coverage, both parameters are already described in the schema (siteUrl and url). The tool description adds no additional semantic context beyond what the schema provides, so a 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 function: checking notification status for a previously submitted URL. It uses a specific verb ('check') and resource ('notification status for a URL'). This distinguishes it from sibling tools like indexing_submit_url and indexing_remove_url.

    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 does not mention prerequisites (e.g., the URL must have been submitted via the Indexing API), nor does it specify that it should be used after submission to verify status. No exclusions or alternative tools are referenced.

    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 exist, so the description must fully disclose behavioral traits. It only states 'Inspect' without clarifying what inspection entails (e.g., indexing status, validity check), potential side effects, rate limits, or authorization requirements. This is insufficient for a batch operation.

    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 extremely concise (5 words), which is efficient but may be overly brief for a batch operation with 4 parameters. It front-loads the core purpose but lacks necessary detail for safe invocation, earning a moderate score.

    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?

    No output schema is provided, and the description omits what the tool returns (e.g., inspection results, status codes). Constraints like the max 5 URLs are only in the schema, not the description. The description is incomplete for an agent to fully understand the tool's behavior.

    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% with descriptions for all 4 parameters. The description adds no additional parameter context beyond what the schema already provides, so the baseline score of 3 applies.

    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 clearly states the action ('Inspect multiple URLs'), the resource ('URLs'), and the context ('for a site in batch'). It distinguishes from the sibling 'inspection_inspect' which likely handles single URL inspection. The verb and resource are specific and unambiguous.

    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 batch inspection of multiple URLs but provides no explicit guidance on when to use this tool versus alternatives like 'inspection_inspect' or other analytics tools. No context on prerequisites or limitations is given, leaving the agent to infer use cases.

    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 responsibility for disclosing behavioral traits. It only states the action 'compare' but does not disclose whether the tool is read-only, requires authentication, or what side-effects may occur. The absence of any behavioral notes (e.g., 'read-only', 'requires credentials') leaves significant ambiguity.

    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, well-crafted sentence of 10 words. It is front-loaded with the main purpose ('Diagnose tracking issues') and includes the key method. Every word earns its place; there is no redundancy or fluff.

    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 having 6 parameters (4 required) and no output schema, the description does not clarify the nature of the comparison output, the metrics returned, or any prerequisites. It fails to provide critical context for a tool that cross-references two external data sources, leaving users uncertain about what the result will be.

    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 each parameter has a clear description in the schema (e.g., 'GSC Site URL', 'GA4 Property ID'). The tool description adds the context that these parameters are used to compare GSC and GA4 data, but this does not substantially enhance understanding beyond the schema. 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: 'Diagnose tracking issues by comparing GSC clicks vs GA4 organic sessions'. It uses a specific verb ('diagnose') and resource ('tracking issues'), and the method is well-defined. This effectively distinguishes it from sibling tools that focus on single-source analytics or other SEO tasks.

    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, context for use, or comparison with sibling tools like analytics_* or seo_* tools. Users must infer usage from the purpose alone.

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

  • Behavior2/5

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

    No annotations exist, and the description does not disclose behavioral traits such as whether removal is permanent, reversible, or requires special permissions.

    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 concise sentence with no extraneous information, front-loading the core action.

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

    Completeness3/5

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

    For a simple delete tool with one parameter and no output schema, the description is minimally adequate but lacks important context such as irreversibility or post-removal effects.

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

    Parameters3/5

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

    The input schema already describes the single required parameter accountId with 100% coverage. The description adds no additional meaning 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 'Remove an authorized account' uses a specific verb and resource, clearly distinguishing it from siblings like accounts_add_site and accounts_list.

    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, nor any prerequisites or context provided.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries the full burden. It only states a prerequisite but does not disclose behavioral traits such as data returned, pagination behavior, error handling, or performance characteristics. This is insufficient for a tool with no annotations.

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

    Conciseness4/5

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

    The description is a single short sentence with a parenthetical, efficiently conveying the core purpose and a key requirement. No wasted words.

    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 lack of output schema and annotations, the description is incomplete. It does not explain what the output looks like, how pagination works (despite limit/offset parameters), or provide examples. The prerequisite is helpful but insufficient for full understanding.

    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 does not add meaning beyond the schema parameters, but it does provide context about the prerequisite, which is not in the schema. It is adequate.

    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 analyzes content performance by Content Group in GA4, specifying the exact resource and action. It distinguishes itself from sibling tools like analytics_page_performance or analytics_top_pages by focusing on Content Groups.

    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 mentions a prerequisite (Content Groups must be configured in GA4 Admin), which is useful. However, it does not provide explicit guidance on when to use this tool versus alternatives, nor does it mention when not to use it.

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

  • Behavior2/5

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

    With no annotations provided, the description carries full burden. It states it returns 'realtime active users' but does not disclose any behavioral traits such as authentication needs, rate limits, data freshness, or whether this is a read-only operation beyond the implied nature of 'get'.

    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 sentence with no extraneous words. It efficiently conveys the core functionality.

    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?

    The description is adequate for a simple tool but lacks details on output format, pagination, or usage context. Given no output schema and many sibling analytics tools, more context would improve 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% with descriptions for both parameters (propertyId, accountId). The description adds context about the breakdown dimensions but does not enhance parameter semantics beyond what the schema already provides. Baseline 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 retrieves realtime active users with breakdowns by page, country, and device. This verb+resource combination is distinct from sibling tools like analytics_time_series or analytics_by_country which are not explicitly realtime.

    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. For example, it doesn't clarify if this is preferred over analytics_query for realtime data, or mention scenarios where this tool should not be used.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries the full burden. It does not disclose important behavioral traits such as read-only nature, authentication requirements, rate limits, or what happens with invalid inputs. The description focuses only on features.

    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 concise sentences that convey purpose and capabilities without redundancy or fluff. Every word adds value.

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

    Completeness2/5

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

    For a tool with 10 parameters and no output schema, the description is too brief. It does not explain return format, error handling, or edge cases, leaving gaps for effective use.

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

    Parameters4/5

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

    Schema coverage is 100%, providing baseline 3. The description adds value by explaining that the tool supports multi-dimensional analysis, metrics selection, and custom granularities, giving context 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 clearly states the tool returns advanced time series data with rolling averages, seasonality, and forecasting. However, it does not distinguish from sibling tools like analytics_trends or analytics_query, which may also provide time series data.

    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 advanced time series analysis by listing features like rolling averages and forecasting, but it does not explicitly state when to use it over alternatives or provide exclusions.

    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 provided, so description carries full burden. It describes what the tool does (get top pages) but does not disclose behavioral traits like auth requirements, rate limits, or whether it is read-only. However, the action implies it is a read operation.

    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 concise sentence that front-loads the action and key parameters. No wasted words.

    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 4 parameters, no output schema, and no annotations, the description is minimal. It covers the core idea but does not explain return values, ordering, or default behaviors beyond what the schema offers. Adequate but not comprehensive.

    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 description adds limited value. It reinforces the 'clicks or impressions' sort and 'last N days' time range, but does not add new semantics beyond what the schema already provides.

    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 gets top performing pages by clicks or impressions. It uses a specific verb ('Get') and resource ('top performing pages'), and mentions key parameters (clicks/impressions, last N days). It is distinguishable from siblings like analytics_page_performance, but does not explicitly differentiate.

    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. The description does not mention scenarios where this tool is preferred over similar tools like analytics_top_queries or analytics_page_performance.

  • Behavior2/5

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

    No annotations provided, and the description only states the basic action. It does not disclose behavioral traits such as authentication requirements, rate limits, idempotency, or error handling.

    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 single sentence that front-loads the main action. No wasted words, but could include a bit more context without losing brevity.

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

    Completeness2/5

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

    Lacks information about prerequisites (e.g., need for a pre-generated key), return values, and setup steps. Incomplete for a tool that requires external configuration.

    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% with descriptions for all parameters. The description adds no additional meaning beyond what the schema provides, so baseline score 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?

    Clearly states the tool submits URLs via the IndexNow API, specifying the verb 'Submit' and resource 'URLs via IndexNow API'. It distinguishes from siblings by mentioning the IndexNow API and supporting search engines (Bing, Yandex).

    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?

    No explicit guidance on when to use this tool versus alternatives like bing_url_submit. The description implies usage for IndexNow-compatible search engines but does not provide context on 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, and the description does not disclose behavioral traits beyond the generic 'remove'. It does not mention whether deletion is reversible, associated side effects, or authorization requirements.

    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.

    Completeness3/5

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

    For a simple delete operation with two parameters, the description is adequate but minimal. It does not discuss return values or post-deletion state, but given the lack of an output schema, this is acceptable. However, it could mention prerequisites like the sitemap being previously submitted.

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

    Parameters3/5

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

    Schema description coverage is 100% with clear parameter descriptions for siteUrl and sitemapUrl. The tool description adds no additional meaning beyond the schema, so baseline score of 3 applies.

    Purpose5/5

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

    The description clearly states the action ('Remove a sitemap') and the resource ('from Bing Webmaster Tools'). It distinguishes from siblings like bing_sitemaps_list and bing_sitemaps_submit by specifying deletion.

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

    Usage Guidelines2/5

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

    The description provides no guidance on when to use this tool versus alternatives such as bing_sitemaps_list or bing_sitemaps_submit. No exclusions or context are given.

    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 disclose behavioral traits. It only states 'Remove a site' without mentioning that deletion is permanent, irreversible, or what data is affected. This is insufficient for a mutation tool.

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

    Conciseness4/5

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

    The description is a single concise sentence with no wasted words. It is appropriately sized for a simple tool, though it could benefit from being slightly more structured.

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

    Completeness2/5

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

    Given the simplicity (1 param, no output schema), the description should cover what happens after deletion (e.g., success response, error cases). It does not, leaving the agent with incomplete context.

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

    Parameters3/5

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

    The schema already describes the single parameter 'siteUrl' as 'The URL of the site to remove'. The description adds no additional meaning, so baseline 3 applies due to 100% schema coverage.

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

    Purpose5/5

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

    The description clearly states the action 'Remove' and the resource 'site from Bing Webmaster Tools', distinguishing it from sibling tools like bing_sites_add and bing_sites_list.

    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 use when needing to remove a site, but provides no explicit guidance on when to use or not use this tool versus alternatives. For a simple delete operation, this is adequate but lacks exclusions.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries the full burden. It does not disclose whether the tool is read-only, required authentication for both services, or what the output format is. This lack of detail limits the agent's understanding of side effects or requirements.

    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, well-formed sentence with no extraneous information. It front-loads the core action and purpose, making it easily scannable for an AI agent.

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

    Completeness3/5

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

    For a tool that combines two separate services (GSC and GA4) and no output schema, the description could provide more context about the expected output (e.g., a list of pages with comparison metrics). While the parameter descriptions are complete, the missing output description and lack of external references leave some 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%, with clear descriptions for each parameter (e.g., 'GSC Site URL', 'GA4 Property ID'). The tool description adds the context of comparing two data sources but does not add further parameter-level semantics 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 action ('Compare'), the data sources ('GSC ranking data with GA4 behavior data'), the scope ('top pages'), and the goal ('find opportunities'). This distinguishes it from sibling tools that focus on single-source analysis.

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

    Usage Guidelines2/5

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

    The description provides no explicit guidance on when to use this tool versus alternatives such as analytics_top_pages or seo_low_hanging_fruit. There is no mention of prerequisites, nor when not to use it.

  • Behavior2/5

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

    The description only states the basic action without disclosing behavioral traits like permanence, error conditions, or authentication requirements. Since no annotations exist, the description carries full responsibility for transparency, which it fails to meet.

    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, concise sentence that front-loads the action. No superfluous words or repetition.

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

    Completeness3/5

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

    For a simple deletion tool with 3 parameters and no output schema, the description is minimally adequate but could explain outcomes (e.g., confirmation) or prerequisites (e.g., siteUrl must be verified).

    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 parameters are well-documented. The description adds no extra meaning beyond what the schema provides, meeting the baseline expectation.

    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 action (Delete), resource (sitemap), and scope (from Search Console or Bing Webmaster Tools). It effectively distinguishes the tool from siblings like sitemaps_submit or sitemaps_list.

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

    Usage Guidelines2/5

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

    No guidance is provided on when to use this tool versus alternatives, such as when to delete vs. list or submit sitemaps. The description lacks any usage context or prerequistites.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries full responsibility. It discloses only the basic function and output categories, without mentioning any behavioral traits such as whether it is read-only, auth requirements, rate limits, or side effects.

    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 sentence of 11 words, front-loading the key information. Every word is necessary and contributes to clarity without redundancy.

    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?

    The tool lacks an output schema, so the description should explain what the response contains. It only says 'audience segmentation' but does not describe the data structure or format. Given no output schema, this is a significant gap.

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

    Parameters3/5

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

    Schema coverage is 100%, and each parameter has a clear description. The tool description does not add additional meaning beyond the schema; it only contextualizes the overall purpose. Baseline 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 verb 'Get', the resource 'audience segmentation', and specifies the segmentation types (New vs Returning, Age, OS). It also adds 'in a single batch', distinguishing it from other analytics tools that might return segments individually.

    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 when to use the tool (to get multiple segmentations at once) but does not provide explicit guidance on when not to use it or alternatives. It lacks exclusions or comparisons with sibling tools.

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

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

    No annotations are provided, so the description carries the full burden. It mentions the analytical scope (device causes, algorithm updates) but does not disclose behavioral traits such as whether the tool is read-only, what data sources it accesses, the nature of the analysis (statistical, API-based), or how results are returned. The brevity leaves significant gaps in understanding the tool's behavior.

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

    Conciseness5/5

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

    The description is a single, front-loaded sentence that efficiently conveys the tool's purpose without any filler. Every word earns its place, and the structure is optimal for quick understanding.

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

    Completeness2/5

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

    For an analytical tool with no output schema and without annotations, the description is insufficiently complete. It fails to explain the result format, any prerequisites (e.g., analytics setup), or how the analysis processes inputs. Given the complexity of traffic drop analysis, an agent would need more context to invoke the tool 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% with clear parameter descriptions (siteUrl as URL, days as lookback with default, threshold as standard deviation sensitivity). The description adds no extra meaning beyond the schema—it does not relate the parameters to the device/algorithm attribution goal. Baseline 3 is appropriate since the schema already documents parameters well.

    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: analyzing a significant traffic drop to attribute it to specific devices (mobile/desktop) or coincide with known Google algorithm updates. It uses a specific verb 'Analyze' and noun 'traffic drop', and the detail about devices and algorithm updates distinguishes it from sibling tools like analytics_anomalies (generic anomaly detection) or analytics_traffic_sources (source-level analysis).

    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 when investigating a significant traffic drop, but it does not provide explicit guidance on when to use this tool versus alternatives like analytics_anomalies or bing_analytics_drop_attribution. No when-not-to-use conditions or prerequisites are mentioned, 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.

  • 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 traits. It only states 'correlate' without disclosing what actions occur (e.g., fetching top pages, making API calls), whether the operation is read-only, or what side effects exist. The lack of output schema or behavioral details leaves the agent guessing about return format or mutations.

    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 concise sentence that immediately conveys the tool's purpose. No unnecessary words, and it is front-loaded with the key action and resources.

    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?

    The tool has 7 parameters (4 required) and no output schema. The description does not explain what the output looks like (e.g., table, correlation coefficient, chart), which is critical for an agent to process results. For a correlation tool without output schema, the description is incomplete.

    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 context by naming the two data sources ('GA4 engagement metrics', 'PageSpeed Insights scores'), but does not elaborate on parameter usage beyond what the schema already provides. The description adds marginal 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 correlates GA4 engagement metrics with PageSpeed Insights scores for top organic pages. It specifies the verb 'correlate', the resources (GA4, PageSpeed), and the scope ('top organic pages'), effectively distinguishing it from siblings like analytics_organic_landing_pages or pagespeed_analyze.

    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 when a user wants to see correlation between engagement and page speed, but it does not explicitly state when to use this tool versus alternatives, nor does it mention when not to use it. No exclusion criteria or alternative tool names are provided.

    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 states the action without disclosing behavioral traits such as failure handling, quota impact, or processing time.

    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, clear sentence with no superfluous words.

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

    Completeness2/5

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

    For a mutation tool with no annotations, output schema, or behavioral details, the description is too minimal to fully guide an agent on success/failure, quota, or async behavior.

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

    Parameters3/5

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

    Schema description coverage is 100%, so the schema already documents both parameters. The description adds no extra meaning 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 uses a specific verb 'submit' and resource 'multiple URLs to Bing indexing' and clearly distinguishes from single URL submission siblings like bing_url_submit.

    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 batch usage but does not explicitly state when to use this tool versus single-url or other alternatives, nor provides any exclusions.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries full burden. It discloses tolerances but omits key behavioral details: whether the tool is read-only, what the response format is, whether it returns pass/fail or actual values, or any auth/rate limit context.

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

    Conciseness5/5

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

    Two sentences, front-loaded with purpose and tolerance. Every word earns its place. No redundancy.

    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?

    No output schema exists, and the description does not explain return values (e.g., boolean, actual value, discrepancy). For a verification tool with 7 parameters and complex logic, the description is too minimal to be fully complete.

    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 3 applies. The description adds no parameter-specific details beyond the schema; 'claim' remains vague. No additional semantic value is provided.

    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: to re-query GSC to verify a specific numeric claim, with explicit tolerances. This distinguishes it from sibling analytics tools that query or analyze data without verification.

    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 when a numeric claim needs verification, but does not explicitly state when to use or not use this tool versus alternatives, nor does it provide prerequisites or exclusions.

    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 the batch submission behavior and daily quotas, but lacks details on error handling, default engine behavior, or partial success outcomes. Since annotations are absent, more context would be beneficial.

    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 with one sentence delivering key information. Front-loaded with action and limits. Could add more context without becoming verbose.

    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?

    Minimally complete for a batch submission tool. Includes quota limits and mentions both engines. Lacks return value description and error handling, which would be helpful given no output schema.

    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 doesn't need to explain parameters much. It adds value by mentioning quotas, but does not clarify parameter formats or defaults beyond what schema provides.

    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 'Submit multiple URLs for indexing in batch.' It uses a specific verb and resource, and the 'batch' distinguishes it from the single-submit sibling tool indexing_submit_url.

    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 quota limits for Google and Bing, which helps with when to use the tool. However, no explicit guidance on when not to use it or alternatives beyond the quota mention.

    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 provided, so description carries full burden. It discloses the tool checks indexing, crawl info, and health, but does not elaborate on what 'health' entails, whether it is read-only, or any rate limits. Basic transparency but lacking depth.

    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 only states the high-level operation and classification categories, but does not disclose any behavioral traits such as data source, update frequency, classification thresholds, or whether the tool returns raw numbers alongside classifications.

    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, zero wasted words. The description is front-loaded with the core action and then the classification detail. Every sentence is meaningful.

    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 4 parameters and no output schema, the description should explain output format more thoroughly. It mentions classification categories but not how results are organized (e.g., list of pages grouped by position, or aggregate). It also omits that siteUrl is required (though schema covers it). Somewhat incomplete for a tool with moderate complexity.

    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 schema already documents parameters (siteUrl, days, minImpressions, limit). The description adds context about per-page and by-position comparison, but does not clarify how these relate to parameters (e.g., position is not a parameter, possibly an output dimension). No additional parameter-specific meaning is provided 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: compare actual CTR per page against industry benchmarks by position and classify results. It uses specific verbs (compare, classifies) and resource (CTR per page, industry benchmarks, position). It distinguishes from sibling tools like analytics_top_pages or seo_low_ctr_opportunities by focusing on benchmarking rather than listing top pages or identifying opportunities.

    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 CTR benchmarking but does not explicitly state when to use this tool vs alternatives (e.g., seo_low_ctr_opportunities or analytics_content_performance). No exclusions or prerequisites are mentioned, leaving the agent without guidance on tool selection.

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

  • Behavior2/5

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

    No annotations are provided, and the description does not disclose behavioral traits such as data retrieval being read-only, any required permissions, or rate limits. The tool is likely a read operation, but this is not clarified.

    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 sentence with no wasted words, front-loading the core purpose and listing metrics efficiently.

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

    Completeness3/5

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

    Given no output schema and no annotations, the description is somewhat lacking. It does not explain return format, whether results are real-time, or if authentication is needed. However, for a simple tool with one parameter, it provides the essential information.

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

    Parameters3/5

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

    The input schema covers the single parameter 'url' with a description. The tool description adds context about the metrics returned but does not add meaning beyond what the schema provides. Schema coverage is 100%, so baseline 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 gets Core Web Vitals for mobile and desktop, listing specific metrics (LCP, FID, CLS, FCP, TTI, TBT). This distinguishes it from sibling tools like pagespeed_analyze.

    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 obtaining core web vitals but provides no explicit guidance on when to use this tool vs alternatives like pagespeed_analyze or other analytics tools.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries the full burden. It discloses accepted input types but does not mention behavioral traits such as error handling, output format, rate limits, or authentication needs, leaving significant gaps.

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

    Conciseness5/5

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

    The description is a single sentence with no fluff, front-loading the tool's purpose and input types. Every word 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?

    While the tool is simple with only two parameters, the description does not explain what the validation output includes or how results are returned. This lack of completeness may hinder an agent in fully utilizing the tool without further context.

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

    Parameters3/5

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

    Schema coverage is 100% with both parameters described in the input schema. The description merely restates the enum values and data types already defined, adding no new meaning beyond what the schema provides.

    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 uses a specific verb ('Validate') and resource ('Schema.org structured data (JSON-LD)'), and lists the input types (URL, HTML, JSON), making the tool's purpose clear and distinct from sibling tools that focus on analytics and SEO.

    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 validating structured data but does not provide explicit guidance on when to use this tool versus alternatives or when not to use it. Sibling tools are quite different, so context is clear but lacks exclusions.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries full burden. It explains the filtering criteria but does not disclose return format, pagination, data source, or authorization requirements, leaving a significant gap in behavioral understanding.

    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, clear sentence that efficiently conveys the core functionality with no wasted words.

    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?

    While the tool has 4 parameters with full schema coverage, there is no output schema, and the description does not hint at the response structure or pagination. For a data-returning tool, this is adequate but incomplete.

    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%, and the description adds no additional meaning beyond what the schema already provides for parameters. 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 verb 'identify', the resource 'queries that lost all traffic (or dropped >80%)', and the comparison 'compared to the previous period'. It effectively distinguishes from sibling tools like analytics_top_queries and seo_low_ctr_opportunities.

    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 identifying lost queries but does not provide explicit when-to-use or when-not-to-use guidance, nor does it mention alternatives. Given the large set of sibling tools, more direction would help selection.

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

  • Behavior2/5

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

    No annotations are provided, and the description does not disclose behavioral traits such as data scope, limitations, or whether it only works for certain search engines (though engine param exists). It lacks details on how 'low CTR' is determined.

    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 efficient sentences, front-loaded with purpose and use case. No wasted words.

    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 no output schema, the description could hint at return values. It adequately covers basic purpose but lacks details on algorithm or expected output format. Satisfactory overall.

    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 additional meaning to parameters beyond what the schema already provides.

    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 finds queries with low CTR relative to ranking position, and suggests a use case (title tag optimization). This distinguishes it from sibling tools like seo_cannibalization or seo_lost_queries.

    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 CTR optimization but does not provide explicit when-to-use or when-not-to-use guidance, nor does it mention 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 carries full burden. It lacks details on side effects, authentication, rate limits, or response (e.g., confirmation). The agent doesn't know if this is a safe read operation or has destructive potential.

    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 concise sentences front-load the action and add a key constraint. No redundant information.

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

    Completeness2/5

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

    Given no output schema and missing annotations, the description is too brief. It doesn't explain what happens after submission, response format, or how to choose between Google and Bing engines despite sibling tools like 'bing_url_submit'.

    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%. The description adds value by noting Google's API limitation for JobPosting/BroadcastEvent, but doesn't elaborate on parameter format or usage beyond 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 action ('Submit a URL for indexing') and resource ('a URL'), and specifies it notifies Google or Bing. It also distinguishes from siblings like 'indexing_remove_url' and 'indexing_batch_submit' by focusing on single URL submission.

    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 gives context for use ('when a page was updated') and mentions API restrictions for Google. However, it lacks explicit when-not-to-use guidance or comparison with peers like 'bing_url_submit' or 'indexing_batch_submit'.

    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 exist, so the description carries full burden. It only states the operation but does not disclose whether it is read-only, requires specific permissions, or has side effects. For a calculation tool, it likely is read-only, but this is 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?

    Single sentence with 12 words, no redundancy, efficiently conveys purpose and output. Excellent conciseness.

    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?

    Without output schema, the description mentions absolute and percentage, which is helpful. However, it does not explain the exact formula (e.g., (current-previous) for absolute) or edge cases like division by zero. For a simple mathematical tool, it is mostly complete but could improve.

    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?

    All three parameters have descriptions in the schema (100% coverage). The description adds 'absolute and percentage' as output context but does not enhance parameter meaning beyond the schema. Baseline 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 verb 'calculate' and the resource 'delta between two traffic metrics', and specifies output includes absolute and percentage. It distinguishes from sibling seo_primitive tools which handle brand, cannibalization, etc.

    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 calculating traffic metric differences but provides no explicit when-to-use or when-not-to-use compared to other analytics tools that may compute similar deltas. No alternatives or exclusions mentioned.

  • Behavior2/5

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

    With no annotations provided, the description carries full burden but only says 'Remove', which is vague. It does not disclose whether the action is reversible, requires permissions, or has side effects (e.g., data loss). This is insufficient for a destructive operation.

    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, front-loaded sentence with no wasted words. Every word is necessary and contributes to understanding the tool's purpose.

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

    Completeness2/5

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

    Given the lack of output schema and annotations, the description should provide more context about return behavior, error handling, or permanence of deletion. It only states the basic action, leaving significant gaps for the agent.

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

    Parameters3/5

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

    The input schema covers 100% of parameters with clear descriptions (siteUrl, engine with enum). The description adds no extra meaning beyond what the schema provides, so a 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 uses the specific verb 'Remove' and identifies the resource as 'a site' and the platforms as 'Search Console or Bing Webmaster Tools'. This clearly distinguishes it from siblings like 'accounts_remove' and 'bing_sites_delete', which target accounts or only Bing.

    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 implies the tool is for removing sites from either Google or Bing. However, it does not explicitly state when to use this over the sibling 'bing_sites_delete', which might cause confusion. It provides clear context but lacks direct alternatives 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, and the description does not disclose any behavioral traits such as mutation, rate limits, authentication needs, or what happens if periods overlap. The agent is left to assume it's a read-only comparison, but without explicit confirmation.

    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 usage suggestion. No extraneous 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?

    Given 5 required parameters and no output schema, the description is adequate for basic understanding but lacks information on what specific metrics are compared, the result format, or the possibility of empty results.

    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 each parameter is described in the schema. The description adds minimal context (e.g., 'first (current)' period vs 'second (comparison)'), which is already in schema descriptions. Baseline 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 uses a specific verb 'compare' and resource 'performance metrics between two date periods', clearly distinguishing it from single-time-series tools like analytics_time_series or analytics_top_pages.

    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 explicitly states 'Useful for week-over-week or month-over-month analysis', giving context for when to use, but does not mention when to avoid or list alternatives.

  • Behavior2/5

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

    No annotations are provided, so the description carries full burden. It calls the operation a 'comprehensive health check' but does not disclose what actions it performs, whether it is destructive, any authorization requirements, or rate limits. The description lacks behavioral detail.

    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 sentence with no filler. It is front-loaded with the action and resource, 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 the simplicity (one optional parameter, no output schema, no annotations), the description is adequate but leaves gaps: it does not explain what constitutes a 'health check', what the output looks like, or potential side effects. A more complete description would add behavioral context.

    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% for the single parameter 'siteUrl', which has a description of 'Optional URL of a specific site to check'. The tool description adds context by explaining that omitting the parameter checks all sites, which aligns with 'one or all'. This adds meaning 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 explicitly states the action ('run') and the resource ('comprehensive health check on one or all verified Bing sites'). It clearly distinguishes from sibling tools like bing_sites_list or bing_sites_add, which have different purposes.

    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 health checks but provides no explicit guidance on when to use this tool versus alternatives (e.g., bing_sites_list, analytics tools). No exclusions or contextual triggers are mentioned.

  • Behavior3/5

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

    With no annotations, the description carries full burden. It discloses that the tool aggregates performance and returns top pages and queries, but omits details on read-only nature, side effects, authentication, or rate limits. This is adequate but not thorough.

    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, concise sentence that immediately conveys the core function and expected output. No extraneous information, making it highly efficient for an agent to parse.

    Purpose5/5

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

    The description clearly states the verb 'aggregate performance' and the resource 'pages matching a URL path pattern', with concrete examples like '/blog/' and '/guides/'. It distinguishes from sibling tools like analytics_top_pages by specifying aggregation over a path pattern rather than individual pages.

    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 path-pattern aggregation but does not explicitly state when to use this tool over alternatives. No guidance on exclusions or prerequisites is given, leaving the agent to infer the appropriate context from examples.

    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?

    Completeness4/5

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

    For a simple analytical tool with no output schema, the description adequately explains the detection logic. However, it does not specify return format or handle edge cases, which would be helpful for an agent. Still, it is mostly complete given the tool's simplicity.

    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?

    All three parameters have descriptions in the schema, achieving 100% coverage. The description adds some context for minClicks and limit but largely reiterates what's already in the schema. Baseline 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?

    Clearly states the tool detects pages with consistent traffic decline over three consecutive 30-day windows with strict monotonic decline. Distinguishes from sibling tools like grain_traffic_drops which likely detect broader traffic drops.

    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 detecting specific decline patterns but no explicit guidance on when to use this tool versus alternatives like grain_traffic_drops or analytics_trends. No when-not-to-use or prerequisites mentioned.

    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?

    With no annotations, the description explains the read-only nature (list), but lacks detail on authorization requirements, rate limits, or the meaning of 'verified.' It adds basic behavioral context but could be more informative.

    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, well-structured sentence with no unnecessary words. It is front-loaded with the main verb and resource.

    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 list tool with one optional parameter and no output schema, the description provides sufficient context to understand the tool's purpose and scope. It could optionally mention the return format, but is still complete enough.

    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% for the single parameter 'engine,' which already has a description and enum. The tool description does not add any further meaning or usage hints beyond what the schema provides.

    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 action (list), resource (verified sites/properties), and scope (across all authorized accounts). It distinguishes this generic site list from sibling tools like 'sites_get' (singular) and 'bing_sites_list' (specific to Bing).

    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 use for listing all sites, but does not explicitly clarify when to choose this tool over alternatives like 'sites_get' (for a single site) or engine-specific listers. No guidance on prerequisites or post-list actions is 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?

    Discloses the method (CLI or browser) and the side effect (starring), but does not detail authentication requirements or idempotency. With no annotations, the description provides some transparency but is 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?

    Two sentences, front-loaded with purpose, each sentence provides value. No unnecessary words or redundancy.

    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?

    The tool has no parameters, yet the description does not clarify which repository is being starred or how it is determined (e.g., a pre-configured repo). This omission leaves the agent without necessary context to invoke the tool correctly.

    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?

    No parameters exist; schema coverage is 100%. The description adds no parameter semantics, but since there are none, the baseline of 4 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 action ('Star the GitHub repository') and the resource, effectively communicating its purpose. It is a distinct utility tool with no similar siblings.

    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 when to use (to support the project) but lacks explicit guidance on prerequisites or alternatives. No mention of when not to use or comparison with other tools.

    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 provided. Description indicates a read-only diagnostic comparison of periods, but does not detail side effects, required permissions, or data access scope. It is adequate but minimal.

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

    Conciseness5/5

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

    Two sentences, front-loaded with purpose and scope. No unnecessary words. Highly 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 no output schema and only three parameters, the description covers the core function well. It could be enhanced with details about output format or prerequisites (e.g., site must be added), but is nearly complete for a simple diagnostic 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 coverage is 100% with clear schema descriptions for all three parameters. The description adds only that the tool compares periods, which relates to the 'days' parameter but does not add significant new semantic meaning.

    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 diagnoses why traffic dropped, listing specific causes (ranking loss, CTR collapse, etc.), and explicitly distinguishes it from siblings by focusing on diagnosis of traffic drops.

    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 implies use when traffic has dropped and you need to know why, comparing current vs prior period. However, it does not explicitly mention when not to use it or alternative tools.

    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 provided. Description does not disclose behavioral traits such as side effects, idempotency, or data freshness. It only states the output content, leaving the agent to assume it's a safe read operation based on context.

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

    Conciseness5/5

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

    Three terse sentences with no wasted words. The critical action ('Start here.') is front-loaded, followed by output description and usage recommendation.

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

    Completeness5/5

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

    For a tool with zero parameters and no output schema, the description sufficiently conveys its role as an entry point, covering purpose and usage. No further detail is 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?

    No parameters exist, so baseline score of 4 applies. The description adds no parameter information because none is needed.

    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 returns a complete map of server capabilities, active platforms, and recommended workflows, positioning it as an initialization tool that differentiates from sibling tools focused on specific analytics, indexing, or site management tasks.

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

    Usage Guidelines5/5

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

    Explicitly instructs to call this once at the beginning of any session, providing clear when-to-use guidance and implying it should be invoked before any other tool.

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

  • Behavior4/5

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

    No annotations provided, but the description implies a safe read-only operation (diagnostics) and covers scope (all connected accounts). Could be improved by explicitly confirming no side effects.

    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 front-loaded with purpose and usage, no unnecessary words.

    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?

    Adequate for a parameterless diagnostic tool; specifies what it does and when to use it. Lacks details on output format but not critical given simplicity.

    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?

    No parameters exist; schema coverage is 100%. Baseline 4 applies as no additional parameter info is needed.

    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 it runs connectivity diagnostics for all connected accounts, distinguishing it from sibling analytics/SEO tools by specifying its troubleshooting role.

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

    Usage Guidelines5/5

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

    Explicitly tells when to use: troubleshooting '0 results' or authentication issues, providing direct actionable context.

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