Server Quality Checklist

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

Latest release: v1.0.0
Disambiguation4/5
Most tools have distinct purposes, but some overlap exists, such as get_user_replies and get_user_actions, which could cause confusion. However, descriptions clarify their differences, and tools like get_topic_posts and get_all_topic_posts are well-differentiated for pagination vs. bulk fetching.
Naming Consistency5/5
All tool names follow a consistent verb_noun pattern, such as get_topic_posts, bookmark_post, and search_forum. The naming is uniform and predictable, making it easy for agents to understand the action and target resource.
Tool Count4/5
With 22 tools, the count is slightly high but reasonable for a forum server covering categories, topics, posts, users, search, and authentication. It provides comprehensive functionality without being overwhelming, though some tools like get_user_actions and get_user_replies could potentially be consolidated.
Completeness5/5
The tool set offers complete coverage for a forum domain, including CRUD-like operations (e.g., login, bookmark, subscribe), extensive read capabilities (e.g., get topics, posts, users, categories), and search functionality. There are no obvious gaps, and agents can perform typical forum interactions without dead ends.
Average 4.2/5 across 22 of 22 tools scored. Lowest: 3.2/5.

How is the quality score calculated?

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

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

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

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

Tool Scores

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions pagination and the return format, which adds useful context beyond basic functionality. However, it lacks details on rate limits, authentication needs, or error handling, leaving gaps for a mutation-free 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured and front-loaded with the core purpose, followed by parameter and return details. The final sentence about follower count adds minor value but doesn't detract significantly, keeping it efficient overall.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's low complexity, 100% schema coverage, and the presence of an output schema, the description is reasonably complete. It covers purpose, parameters, and returns adequately, though it could benefit from more behavioral context like error cases or pagination defaults.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents both parameters thoroughly. The description repeats the parameter info without adding meaningful context like format constraints or usage examples, earning the baseline score for adequate but redundant coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose with a specific verb ('fetch') and resource ('list of users following a specific user'), making it easy to understand what it does. However, it doesn't explicitly differentiate from sibling tools like 'get_user_following' or 'get_user_summary', which prevents a perfect score.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools like 'get_user_following' (which might fetch users a person follows) or 'get_user_summary' (which might include follower info), leaving the agent without 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.
Behavior3/5
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 that the tool fetches data (implying read-only behavior) and mentions pagination via the 'offset' parameter, which adds useful context. However, it doesn't cover other behavioral aspects like rate limits, authentication needs, error conditions, or what 'UserReactions object' contains beyond 'reaction data'. The description adds some value but leaves gaps.
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 appropriately sized and front-loaded: the first sentence states the purpose clearly, followed by parameter and return value notes, then usage guidance. Each sentence adds value (e.g., explaining the purpose of fetching reactions). It could be slightly more structured (e.g., separating sections), but it's efficient with zero waste.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity (2 parameters, read-only operation), the description is reasonably complete. It covers purpose, parameters, returns, and usage context. Since an output schema exists (implied by 'Returns a UserReactions object'), the description doesn't need to detail return values. However, with no annotations, it could better address behavioral aspects like error handling or data scope.
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 both parameters ('username' and 'offset') well-documented in the schema. The description adds minimal semantics: it restates 'username' as 'The user's handle' and 'offset' as 'Pagination offset', which doesn't provide additional meaning beyond the schema. Since the schema does the heavy lifting, 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: 'Fetch a user's post reactions (likes, etc.)'. It specifies the verb (fetch) and resource (user's post reactions), making the function unambiguous. However, it doesn't explicitly differentiate from sibling tools like 'get_user_actions' or 'get_user_replies', which might also involve user activity 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 provides some usage context: 'Use to see what content a user has reacted to, which can indicate their interests and values.' This implies when to use the tool (for analyzing user interests via reactions), but it doesn't explicitly state when not to use it or name alternatives among siblings (e.g., 'get_user_actions' for broader activity). The guidance is helpful but not comprehensive.
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 provided, the description carries full burden for behavioral disclosure. It reveals pagination behavior through the 'page' parameter documentation and describes the return format (FollowList object structure). However, it doesn't mention rate limits, authentication requirements, error conditions, or whether this is a read-only operation (though 'fetch' implies reading).
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 well-structured with clear sections (purpose, args, returns, use cases). It's appropriately sized at 6 sentences, though the 'Args:' section somewhat duplicates schema information. Most sentences earn their place by providing distinct information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has an output schema (implied by 'Returns a FollowList object'), the description doesn't need to fully explain return values. It provides adequate context for this read-only data retrieval tool, though it could benefit from mentioning authentication requirements or rate limits given no annotations are provided.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already fully documents both parameters. The description repeats the parameter information in the 'Args:' section but doesn't add meaningful semantic context beyond what's in the schema (e.g., format expectations for username, pagination strategy details). Baseline 3 is appropriate when schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose with 'Fetch the list of users that a user follows' - a specific verb+resource combination. It distinguishes itself from sibling tools like get_user_followers (which would fetch followers rather than following), though it doesn't explicitly mention this distinction in the description itself.
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 'Use to:' section provides clear context about when to use this tool ('Discover influential users', 'Find related experts', 'Map social connections'). However, it doesn't explicitly state when NOT to use it or mention specific alternatives among the sibling tools (like get_user_followers for the reverse relationship).
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 provided, the description carries the full burden. It discloses that the tool returns session information and authentication status, which is useful behavioral context. However, it doesn't mention potential errors, rate limits, or other operational traits beyond the basic return structure.
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 front-loaded with the core purpose, followed by details on the return object and usage guidance. Every sentence adds value without redundancy, making it efficiently structured and appropriately sized for the tool's simplicity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's low complexity (0 parameters, output schema exists), the description is mostly complete. It explains what the tool does and what it returns, but lacks details on error handling or edge cases, which holds it back from a perfect score.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has 0 parameters, and schema description coverage is 100%. The description doesn't need to add parameter semantics, so it meets the baseline of 4 for zero-parameter tools, as it appropriately focuses on output and 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 clearly states the tool's purpose ('Get information about the current session') with a specific verb and resource. It distinguishes itself from siblings by focusing on session/authentication status rather than user data, topics, or posts, though it doesn't explicitly name alternatives.
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 provides clear context for usage ('Use to verify authentication status'), which implicitly guides when to use it. However, it doesn't explicitly state when not to use it or name specific alternatives among the sibling 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 are provided, so the description carries the full burden. It discloses that the tool fetches data (implied read-only) and describes the return structure, but lacks details on behavioral traits like error handling, rate limits, authentication needs, or whether it's idempotent. The description adds some context about badge types but misses key operational aspects.
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 appropriately sized and front-loaded with the core purpose. However, the 'Args' section repeats schema info unnecessarily, and the 'Badges indicate' and 'Use to assess' sections, while helpful, could be more integrated. It's efficient but has minor structural redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's low complexity (2 parameters, 1 required), 100% schema coverage, and the presence of an output schema (implied by 'Returns a UserBadges object'), the description is mostly complete. It explains the purpose, usage context, and return structure, though it lacks behavioral details like error cases or performance considerations.
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 fully. The description repeats the parameter info in the 'Args' section without adding meaning beyond the schema (e.g., explaining why grouping matters or format details). This meets the baseline of 3 when schema coverage is high.
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 'fetch' and resource 'badges earned by a user', making the purpose specific. It distinguishes from siblings like 'list_users_with_badge' (which lists users with a badge) by focusing on badges for a specific user, and from 'get_user_summary' by targeting badges specifically rather than general user data.
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 provides clear context for when to use this tool: 'to assess user experience and trustworthiness' based on badges indicating participation, community recognition, and special achievements. However, it does not explicitly state when not to use it or name alternatives (e.g., 'get_user_summary' for broader user info), which prevents a perfect score.
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 provided, the description carries the full burden of behavioral disclosure. It mentions pagination via 'offset' and returns 'a dictionary with user badge information', which adds some context beyond the schema. However, it lacks details on permissions, rate limits, or what specific information the dictionary contains, leaving gaps 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured and front-loaded with the core purpose, followed by parameter details and usage guidelines. Every sentence earns its place: the first states the action, the second and third explain parameters, the fourth describes returns, and the fifth provides usage context, with no wasted 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?
Given the tool's moderate complexity (2 parameters, no annotations, but with output schema), the description is mostly complete. It covers purpose, parameters, returns, and usage, but lacks behavioral details like permissions or rate limits. The presence of an output schema reduces the need to explain return values, but more context would enhance completeness for a tool with no annotations.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents both parameters thoroughly. The description repeats 'badge_id: The numeric badge ID' and 'offset: Pagination offset (optional)', adding no extra meaning beyond the schema. This meets the baseline of 3 when schema coverage is high, but no additional 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 verb 'List' and resource 'users who have earned a specific badge', making the purpose specific and actionable. It distinguishes from siblings like 'get_user_badges' (which gets badges for a user) by focusing on users for a badge, establishing clear differentiation.
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 provides explicit usage context: 'Use to find community members with specific achievements or recognition levels', which clearly indicates when this tool is appropriate. However, it does not specify when not to use it or name alternatives among siblings, such as 'get_user_badges' for a different perspective.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses that the tool returns a list of UserAction objects and mentions pagination via offset, which adds useful context. However, it lacks details on permissions, rate limits, error handling, or the structure of UserAction objects, leaving behavioral gaps for a tool with no annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a clear purpose statement, parameter details in an 'Args' section, return information, and usage guidelines. It's front-loaded and efficient, though the bulleted list for filter values adds some length but is justified for clarity. Every sentence earns its place without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity (3 parameters, no annotations, but with an output schema), the description is fairly complete. It covers purpose, parameters, returns, and usage guidelines. The output schema likely defines UserAction objects, so the description doesn't need to detail return values. However, it could improve by addressing behavioral aspects like authentication or limits.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents all parameters thoroughly. The description adds minimal value beyond the schema by listing common filter values in a bulleted format, but it doesn't provide additional semantics like edge cases or usage examples. This meets the baseline for high schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
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 ('fetch a user's activity feed') and resource ('user'), distinguishing it from siblings like get_user_replies or get_user_topics by emphasizing 'detailed activity analysis beyond just replies.' It provides a verb+resource+scope combination that is precise and differentiated.
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?
The description explicitly provides when to use this tool ('for detailed activity analysis beyond just replies') and when not to ('for most cases, get_user_replies or get_user_topics are simpler'), naming specific alternatives. This gives clear guidance on tool selection relative to siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It discloses the pagination behavior ('Paginate by incrementing the page parameter') and the return format (list of topic objects with specific fields), but doesn't mention rate limits, authentication requirements, or error conditions that might be relevant for a user query 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 well-structured with clear sections: purpose statement, args explanation, returns format, and usage guidelines. It's appropriately sized but could be slightly more concise by avoiding repetition of parameter descriptions already in the schema.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has an output schema (implied by 'Returns a list of topic objects'), the description doesn't need to explain return values in detail. It provides good context about usage scenarios and pagination behavior, though it could benefit from mentioning authentication requirements or error handling for a user query tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents both parameters fully. The description repeats the parameter explanations but doesn't add meaningful semantics beyond what's in the schema (e.g., format constraints for username, pagination strategy details). Baseline 3 is appropriate when schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'fetch' and resource 'topics created by a specific user', distinguishing it from siblings like get_user_replies or get_user_actions which focus on different user activities. It specifies the exact scope of what's being retrieved.
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?
The description provides explicit use cases: 'See what discussions a user has initiated', 'Find expert users in specific areas', and 'Research a user's areas of interest'. It also mentions pagination guidance, though it doesn't explicitly contrast with alternatives like get_user_replies.
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?
With no annotations provided, the description carries full burden and does well by disclosing key behaviors: it describes pagination mechanics ('Paginate with offset in increments of 30'), specifies the return format (list of UserAction objects with fields), and implies read-only nature through 'Fetch'. It doesn't mention rate limits or auth needs, but covers essential operational details.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured and appropriately sized, with clear sections (purpose, args, returns, usage, pagination) and no wasted sentences. Each part adds value, such as explaining the return structure and providing usage examples, making it easy to scan and understand.
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?
Given the tool's moderate complexity, 100% schema coverage, and presence of an output schema (implied by 'Returns a list of UserAction objects'), the description is complete enough. It covers purpose, parameters, return values, usage scenarios, and pagination behavior, leaving no critical gaps for an AI agent to invoke it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents both parameters fully. The description repeats parameter info (e.g., 'offset: Pagination offset (0, 30, 60, ...)') without adding significant meaning beyond the schema, such as explaining why increments of 30 are used or constraints on username format. Baseline 3 is appropriate as the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
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 with specific verb ('Fetch') and resource ('replies/posts made by a user in other topics'), distinguishing it from siblings like get_user_topics (user's own topics) and get_user_actions (broader actions). It precisely identifies what is being retrieved and from where.
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 provides clear usage context with 'Use this to:' examples (e.g., 'See a user's contributions across topics'), which helps understand when to apply this tool. However, it doesn't explicitly state when not to use it or name specific alternatives among siblings, such as get_user_actions, which might overlap in functionality.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It discloses that the tool returns a comprehensive summary object with specific fields, but doesn't mention behavioral aspects like rate limits, authentication requirements, error conditions, or whether this is a cached/real-time view.
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?
Well-structured with clear sections (Args, Returns, Use cases) and front-loaded purpose. Some sentences could be more concise (e.g., 'The summary provides a quick overview without fetching individual post histories' could be tightened), but overall efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has an output schema (Returns section details the structure) and 100% schema coverage for the single parameter, the description provides adequate context. It explains the tool's purpose, usage scenarios, and what information it provides, though could benefit from mentioning any limitations or prerequisites.
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 description coverage is 100%, so the baseline is 3. The description adds value by explaining the parameter's case-insensitive nature and providing context about what 'username' represents ('user's handle'), elevating it above the minimum viable level.
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 ('Fetch a comprehensive summary') and resource ('user's profile'), distinguishing it from sibling tools like get_user_badges or get_user_topics by emphasizing it provides a holistic overview rather than specific components.
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 states when to use this tool ('Evaluate a user's credibility and experience', 'Find their most valuable contributions', 'Understand their participation level') and when not to use it ('without fetching individual post histories'), providing clear alternatives to more granular sibling tools.
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?
With no annotations provided, the description carries the full burden and does well by explaining ranking criteria ('engagement metrics like recent replies, views, and likes'), pagination behavior, and return format. It also includes example response interpretation for behavioral context, though it could mention rate limits or authentication needs.
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 well-structured with clear sections (purpose, usage guidelines, args, returns, examples) and front-loaded key information. It could be slightly more concise by avoiding redundancy in the Args section, but overall it's efficient with zero waste.
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?
Given the tool's moderate complexity, no annotations, and the presence of an output schema, the description is complete. It covers purpose, usage, parameters, return values, and behavioral interpretation, providing sufficient context for an AI agent to use the tool effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description coverage is 100%, so the baseline is 3. The description adds minimal value beyond the schema by restating the parameter in the Args section ('page: Page number for pagination (0-indexed)') but doesn't provide additional semantics like format details or usage nuances.
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 with specific verb ('fetch') and resource ('currently trending/hot topics from USCardForum'), distinguishing it from siblings like get_new_topics or get_top_topics by specifying 'most actively discussed topics right now' based on engagement metrics.
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?
The description explicitly provides three use cases ('See what the community is currently discussing', 'Find breaking news or time-sensitive opportunities', 'Discover popular ongoing discussions'), which guide when to use this tool versus alternatives like get_new_topics or get_top_topics.
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?
With no annotations provided, the description carries the full burden and does well by disclosing key behaviors: it's a read operation (implied by 'fetch'), returns sorted results (newest first), explains that results may have fewer replies, and mentions pagination. It doesn't cover rate limits or authentication needs, but provides substantial 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?
Well-structured with purpose first, then usage guidelines, parameters, return values, and a tip. Some redundancy exists (pagination info appears in both description and schema), but overall it's appropriately sized and front-loaded with essential information.
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?
Given the tool's moderate complexity (single optional parameter), no annotations, but with an output schema that documents return values, the description provides excellent contextual completeness. It covers purpose, usage, behavior, parameters, and includes helpful tips without needing to explain return values since the output schema handles that.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already fully documents the single parameter. The description repeats the pagination information in the Args section but adds no additional semantic context beyond what's in the schema, meeting the baseline expectation.

Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden and does an excellent job disclosing behavioral traits. It explains the automatic pagination mechanism, provides safety guidance about response size limits for large topics, describes how parameters interact (start_post_number, end_post_number, max_posts), and references the return structure. The only minor gap is not explicitly mentioning whether this is a read-only operation, though 'fetch' implies it.
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 well-structured with clear sections: purpose statement, parameter explanations, important notes, use cases, return information, and pro tip. While comprehensive, some redundancy exists (parameter descriptions partially repeat schema info). Every sentence adds value, but it could be slightly more concise by eliminating schema repetition.
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?

Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with clear sections (Args, Use this FIRST, Returns, Strategy), but it could be more concise by avoiding repetition (e.g., the topic_id explanation is duplicated in Args and schema). Most sentences earn their place by adding useful context, though some trimming is possible.
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?
Given the tool's complexity (single parameter, no annotations, but with an output schema), the description is complete. It explains the purpose, usage, parameters, return values (with a TopicInfo object detailed), and strategic advice, compensating for the lack of annotations. The output schema means return values don't need further explanation.
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?

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 states when to use ('if you need authenticated features like: Reading notifications, Bookmarking posts, Subscribing to topics') and when not to use ('Most read operations work without authentication'). Provides clear alternatives by naming specific sibling tools that require authentication versus those that don't.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
