Server Quality Checklist

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

Latest release: v0.5.1
Disambiguation5/5
Each tool targets a specific functionality with clear descriptions that distinguish overlapping areas (e.g., generate_caption vs generate_text, ai_reply_suggestion vs chat_with_bot). No two tools serve the same purpose, making selection unambiguous.
Naming Consistency5/5
The vast majority of tools follow a consistent verb_noun pattern (e.g., generate_image, list_customers, remove_background). Only a few minor exceptions (ai_reply_suggestion, lip_sync, virtual_try_on) exist, but they are still intuitive and do not break the overall consistency.
Tool Count4/5
With 43 tools covering a wide range of features (content generation, social media, CRM, products, competitors, templates), the count is large but justifiable for a comprehensive platform server. It is slightly heavy but not excessive for the scope.
Completeness3/5
Core workflows for content generation and social media interaction are well-covered, but there are notable gaps in CRUD operations for entities like social posts, customers, products, and competitors (no update/delete tools). This limits the ability to fully manage resources via tools alone.
Average 3.9/5 across 43 of 43 tools scored. Lowest: 2.9/5.

How is the quality score calculated?

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

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

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

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

Tool Scores

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description must disclose behavior. It mentions cost and AI model but lacks details on output handling, rate limits, or whether tracks are saved or returned. Incomplete for a generation 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?
Concise, with four sentences covering purpose, features, and cost. No fluff, but could benefit from structured bullet points for readability.
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 output schema exists, description may omit return details, but it lacks context on generation duration, success/failure indicators, or how to retrieve the generated music. 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 coverage is 100%, so the baseline is 3. Description adds context about Turkish and English lyrics (relevant to prompt) and cost, but no additional semantic details 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 it generates music using AI, with options for vocals or instrumental, which distinguishes it from siblings like generate_music_video. However, it could be more specific about what 'full songs' entails.
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 generate_text or generate_image. It provides cost and language support but no direct comparison to 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?
With no annotations, the description must disclose behavioral traits but fails to mention idempotency, permissions, duplicate handling, or side effects. The single sentence 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 concise sentence with no redundancy. While it could be expanded with guidelines, it is appropriately short for a straightforward creation 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?
Although an output schema exists (reducing need for return value docs), the description lacks behavioral context, error hints, and prerequisites, leaving it incomplete for a tool with 9 parameters and 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 9 parameters are fully described in the schema (100% coverage), so the description adds no new meaning. Baseline is 3; no extra value 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 action ('Create') and the resource ('new product in your organization's catalog'), distinguishing it from sibling tools like 'list_org_products' or 'update_product_stock'.
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 vs alternatives, such as checking if the product already exists or updating stock. Usage context is entirely absent.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must convey behavioral traits. It mentions cost (~2 credits) but does not disclose whether the tool is read-only, destructive, or any side effects (e.g., token usage, rate limits). For a generative tool, 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?
The description is concise at three sentences, front-loading the core purpose. Each sentence adds value: purpose, examples, cost. 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?
Given the tool's complexity (4 parameters, output schema exists), the description covers the basic purpose and examples but lacks usage context, error handling, or return value explanation. The output schema likely covers return values, so the description is minimally adequate.
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 adequately. The description adds no additional meaning beyond the schema; it mentions the sub_mode values implicitly through examples but does not elaborate on temperature or max_tokens.
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 clear verb 'Generate' and specifies the resource 'text content using Gemini AI'. It lists example outputs (scripts, storyboards, lyrics, marketing copy), which helps differentiate from sibling tools like generate_caption (more focused) or generate_hashtags (narrower). However, it does not explicitly state that this is the general-purpose text generation tool, leaving some ambiguity.
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 by listing example outputs, but it does not state when to use this tool versus other text-generation siblings (e.g., generate_caption for captions, generate_hashtags for hashtags). No explicit when-not or alternative recommendations 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 does not disclose behavioral traits such as side effects, permissions, or idempotency. For a read operation, information about caching or data freshness would be helpful.
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 is concise and front-loaded. However, it could incorporate more detail without losing conciseness, such as mentioning the source of competitor_id.
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 presence of an output schema and only two parameters, the description is minimally adequate. Missing behavioral transparency and usage guidelines, but the core purpose is clear.
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 description does not add significant meaning beyond what is 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?
The description clearly states the action 'Get detailed info' and the resource 'a single competitor'. It effectively distinguishes from sibling tools like 'list_competitors' and 'compare_competitors' by focusing on a single entity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives. The schema implies using competitor_id from list_competitors, but the description lacks direct context or exclusion criteria.
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 for behavioral disclosure. It mentions generating 'AI-optimized' and 'trending' hashtags, but omits any details about side effects, resource consumption (e.g., API credits), or authorization requirements. This is minimal transparency for a tool that likely consumes AI model quotas.
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 primary purpose, with no wordiness or redundant information. Every sentence 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?
With 4 parameters, an output schema, and sibling tools like 'generate_caption', the description is sufficiently complete but lacks details like the number of hashtags generated or platform-specific behavior. The output schema likely covers return values, so the description meets a minimum threshold but could hint at output structure.
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, with detailed descriptions for each parameter. The tool's description adds 'based on your caption content,' which essentially restates the schema's caption parameter description. Given high schema coverage, the baseline is 3, and the description adds no extra 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's function: generating AI-optimized hashtags for a social media post. It uses a specific verb ('Generate') and resource ('hashtags'), and distinguishes it from siblings like 'generate_caption' or 'analyze_image'.
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 when generating a caption or analyzing content. No when-to-use or when-not-to-use context is given, leaving the agent to infer usage solely from the tool name.
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. It only states that the AI animates the face to appear as if speaking and mentions a cost of ~14 credits. It lacks details on processing time, output format, photo requirements, or whether the tool is read-only (it is generative, so not read-only). This minimal disclosure is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very concise: three sentences plus a cost note. It front-loads the main purpose and adds relevant context without unnecessary repetition or fluff. Every sentence earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema, the description does not need to explain return values. It covers the core purpose and usage, but lacks behavioral details (e.g., limitations, processing time) and does not mention prerequisites. Overall it is adequate but has noticeable 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?
The input schema has 100% description coverage, with each parameter already explained concisely (prompt: speech/dialogue, image_url: URL of face photo). The description does not add any additional parameter semantics beyond what the schema provides, so the baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool creates a talking avatar from a photo using AI lip sync. It specifies the verb 'create', the resource 'talking avatar', and the method 'AI lip sync', distinguishing it from other media tools like generate_video or swap_face.
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 it's great for presentations, social media, and content creation, implying appropriate use cases. However, it does not provide explicit guidance on when not to use this tool or suggest alternatives among the many sibling 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 must convey behavioral traits. It only states the tool reads messages, but does not disclose any side effects, authentication needs, rate limits, or error conditions.
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 succinct sentences that clearly communicate the tool's purpose without any superfluous words. Each sentence 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?
The tool is low in complexity and has a high schema coverage and an output schema. The description covers the basics but lacks behavioral details; however, it is adequate for a simple read operation.
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 extra meaning beyond what the schema already provides for the parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'read' and resource 'messages in a social media conversation', and specifies 'full message history' for DM or comment threads. This distinguishes it from siblings like list_inbox (list) and reply_to_message (write).
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 vs alternatives like list_inbox or reply_to_message. The parameter description hints that conversation_id comes from list_inbox, but the description itself lacks such 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 full burden. It mentions cost (~6 credits) and states the output is a 'realistic image', but does not disclose behavioral traits like request limits, input constraints, or potential failure modes. Given the lack of annotations, the description should provide more operational 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 very concise: 4 short sentences, each adding value. It front-loads the purpose and quickly explains the process. No unnecessary 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?
Given the tool's moderate complexity (AI image generation), the description covers the main inputs and output (realistic image). It mentions cost but lacks details on image resolution, style constraints, error handling, or result format. The presence of an output schema partially compensates, but overall completeness is adequate not excellent.
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?
Input schema has 100% description coverage, so baseline is 3. The description largely restates the schema (e.g., 'upload a photo' for image_url, 'describe the clothing' for prompt) without adding new meaning or constraints 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's purpose: virtual clothing try-on using AI. It specifies the action (upload photo, describe clothing, generate image) and explicitly distinguishes from siblings like 'generate_image' or 'swap_face' by focusing on clothing try-on.
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 a use case ('Perfect for e-commerce and fashion'), but lacks explicit when-not-to-use or alternatives. For a server with many image-generation siblings, more guidance on when to choose virtual_try_on over, say, 'generate_image' or 'swap_face' would be beneficial.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full responsibility. It states the AI 'reads the conversation context and suggests an appropriate reply,' indicating a non-destructive read operation. However, it does not explicitly state that it does not modify anything, nor does it mention authorization requirements or rate limits. The description is reasonably transparent but could be more 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 three sentences long, front-loaded with the main purpose, and contains no redundant information. Every sentence adds necessary context: what the tool does, how it works, and customization option. 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 the presence of an output schema and 100% parameter coverage, the description covers the key functionality. It explains the tool's purpose and customization. However, it lacks mention of prerequisites (e.g., conversation must exist) or potential errors, which would make it fully complete. Still, for a straightforward suggestion tool, it is adequate.
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?
Input schema coverage is 100%, so each parameter has a description in the schema. The tool description adds value by stating that the system prompt can customize behavior, which aligns with the schema. However, it does not provide additional semantic meaning beyond what the schema already conveys, such as the purpose of conversation_id and account_id. 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's function: 'Get an AI-generated reply suggestion for a social media conversation.' The verb 'get' and resource 'reply suggestion' are specific, and it differentiates from siblings like 'generate_text' (general text) and 'reply_to_message' (manual reply) by focusing on AI-generated suggestions for social media.
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 explicit guidance on when to use this tool versus alternatives such as 'generate_text' or 'chat_with_bot'. It lacks when-not-to-use scenarios and does not mention prerequisites like conversation existence. The only hint is the mention of 'system prompt' customization, but no direct usage advice.
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 description carries full burden. It states the tool lists competitors (read operation) but does not explicitly confirm non-destructive behavior, rate limits, data freshness, or any side effects. This is insufficient for a standalone disclosure.
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 sentences, each adding value: purpose, scope of tracking, and prerequisites. No fluff, front-loaded with main action.
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 output schema exists, return format is covered. Description covers purpose, scope, and requirements. Could briefly mention pagination behavior (e.g., ordering) but otherwise complete for a listing 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?
Input schema has 100% description coverage, so baseline is 3. The description adds no additional meaning beyond the schema; it only implicitly mentions org_id override. No extra context for limit/offset.
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 'List competitors tracked under your organization' with specific verb and resource. It distinguishes from siblings like 'get_competitor' and 'compare_competitors' by detailing what competitor tracking includes (crawling, social, marketplace).
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?
Description mentions prerequisites ('enterprise subscription with org-bound API key') but does not explicitly guide when to use this tool versus alternatives like get_competitor or compare_competitors. Usage is implied but not contrasted.
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 the description carries full burden. It mentions 'reply' which implies mutation, but lacks details on side effects, authentication requirements, rate limits, or whether the reply is sent immediately. The description is minimal on 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?
Two sentences are front-loaded with the main action and then provide platform context. Every word earns its place; no redundancy or fluff.
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 output schema exists (not shown), the description adequately covers the tool's core purpose and parameters. It lacks usage guidelines but is otherwise complete for a simple reply tool. A higher score would require explicit guidance on alternatives.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% description coverage, so each parameter is already documented. The tool description adds platform context but not parameter-specific 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.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool replies to social media messages/DMs in existing conversations, specifying platforms like Instagram, Facebook, WhatsApp. This is a specific verb+resource, and it distinguishes from sibling tools like create_social_post or bulk_message.
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 replying in existing conversations, but does not explicitly state when not to use it or suggest alternatives. For instance, it doesn't mention that starting a new conversation might require a different tool, leaving some ambiguity.
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, description should disclose behaviors like async execution, rate limits, or error handling. It only describes what the tool does, not its 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?
Concise two-sentence description with a clear first sentence. Could be slightly more structured but no unnecessary 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 output schema exists and schema coverage is 100%, description is mostly complete for purpose and targeting. Missing behavioral details are notable but not critical for basic 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 has 100% description coverage, so baseline is 3. Description reiterates targeting options but does not add significant meaning beyond schema. It mentions media_urls but no extra nuance.
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 tool sends messages to multiple customers at once, with use cases (promotions, announcements) and targeting methods (IDs, tag, platform). Distinguishes well from siblings like reply_to_message and send_shipping_info.
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?
Description gives general usage scenarios but lacks explicit guidance on when not to use or comparison with alternatives. It does not mention that sending to specific IDs vs tag vs platform are mutually exclusive or how they interact.
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?

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%, so baseline is 3. Description adds value by explaining smart routing for model='auto' and stating the credit cost, which is absent from 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?
Clearly states 'Generate an image using AI' - a specific verb and resource. The description distinguishes from sibling tools like generate_text or generate_video by explicitly mentioning image generation and model options.

Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise with three short sentences, each adding value. No redundant information. It is front-loaded with the core purpose.
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 simplicity (zero parameters, output schema present), the description fully explains the purpose, return values, and cost. No gaps remain.
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 zero parameters, and the schema coverage is 100% (empty properties). Per guidelines, baseline for 0 params is 4. The description adds no parameter info 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 checks the YaparAI credit balance and specifies the exact return values (current balance, total used, currency). This is a specific verb+resource combination that distinguishes it from sibling tools.
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 notes that no credits are charged for this operation, providing clear context on when to use it. While it does not mention alternatives or exclusions, the free-of-charge nature is a strong usage guideline.
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?
The description explicitly states 'No credits are charged for this operation,' which is a key behavioral trait. It also describes the return structure. No annotations are provided, but the description covers important behavioral aspects.
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 four sentences, each serving a distinct purpose: stating the action, detailing the return information, noting utility, and clarifying no cost. No unnecessary words.
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 has an output schema and no parameters, the description is complete. It explains the purpose, return fields, utility, and cost-free nature.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero parameters, so the description does not need to add parameter semantics. The baseline for 0 parameters is 4 per calibration.
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 it lists all available AI generation models with their credit costs and details (mode identifier, description, credit cost, type). This action is distinct from sibling tools like generate_image or generate_video, which actually generate content.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description indicates the tool is useful for understanding what can be generated and costs, implying it should be used before generation. It lacks explicit when-not-to-use or alternatives, but the context is clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
