Server Quality Checklist

75%
Profile completionA complete profile improves this server's visibility in search results.
  • Latest release: v0.1.2

  • Disambiguation5/5

    Each tool targets a distinct function: decision and reason are separate reasoning types, get_balance and list_offers cover account/marketplace, memory tools handle storage. No overlap.

    Naming Consistency3/5

    Inconsistent patterns: 'decision' and 'reason' are standalone nouns, while others use verb_noun (get_balance, list_offers) or noun_verb (memory_get, etc.). Some mixed conventions.

    Tool Count5/5

    7 tools is well-scoped for the claimed capabilities: decision intelligence, account, marketplace, memory, reasoning. Each tool earns its place.

    Completeness2/5

    Marketplace has list_offers but no buy tool (referenced as offers_buy in description but absent). Missing delete for memory. Reasoning and decision tools stand alone without integration. Gaps cause dead ends.

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?

    No annotations are provided, so the description carries the full burden. It discloses the return format (Decision, Confidence, Reasoning, Risk level) and cost ('~1000 sats per call'), but lacks details about the underlying model, accuracy, limitations, or side effects. The transparency 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 concise and well-structured: it starts with the primary purpose, lists output components, provides usage guidance, mentions cost, and specifies return format. Every sentence adds value without redundancy.

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

    Completeness3/5

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

    Given that an output schema exists (context signal indicates 'Has output schema: true'), the description need not detail return values. However, it provides the essential context of use cases, cost, and output format. It lacks information about model limitations, accuracy, or edge cases, which would be valuable for a decision 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%, with each parameter having a clear description and examples in the context parameter. The tool description does not add significant meaning beyond the schema, as it focuses on overall behavior rather than parameter details. The baseline of 3 is appropriate given high 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 clearly states the tool provides structured decision intelligence with confidence and risk assessment, and lists the specific output components. However, it does not explicitly differentiate from the sibling tool 'reason', which may perform similar reasoning tasks, leaving some ambiguity about when to use each.

    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 guidance on when to use the tool: 'Best for binary or multi-option choices with real stakes — investment decisions, operational choices, strategic pivots.' It gives clear context and examples but does not mention when not to use it or suggest alternative tools like 'reason'.

    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 cost (~500 sats) and output format (string). However, it does not mention side effects, authentication needs, rate limits, or other behavioral traits. Adds some value but not comprehensive.

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

    Conciseness5/5

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

    Description is short (5 sentences), front-loaded with purpose, and every sentence adds value: purpose, use cases, best-fit, output, cost. No 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 moderate complexity (2 params, output schema exists), description covers purpose, use cases, output format, and cost. Missing potential details like error handling or limits, but sufficient for the tool type.

    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 beyond the schema; it only states the output format. No extra parameter context 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 'strategic reasoning' on 'any question or topic', and distinguishes itself from sibling tools by specifying use cases like open-ended analysis, market commentary, and research, contrasting with binary yes/no questions.

    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?

    Explicitly says when to use (open-ended analysis, nuanced thinking) and what it's best for. Implies not for binary questions, but does not name an alternative tool like 'decision'. Provides clear context but lacks explicit exclusion.

    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 the return format (JSON list with fields) and cost ('Free'), but does not explicitly confirm the tool is read-only, non-destructive, or idempotent. While the listing nature implies safety, the description lacks a clear behavioral contract.

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

    Conciseness5/5

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

    The description is concise (two short paragraphs plus a line for cost/returns) and front-loaded with the main purpose. Every sentence adds value with no redundancy or wasted 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's low complexity (one optional parameter, no required fields), the description fully covers what the tool does, how to use it, and what it returns. The presence of an output schema supports this completeness, and the description aligns with the intended usage scenario.

    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 the single parameter 'category' already described in the schema. The main description adds no new parameter-level details 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.

    Purpose5/5

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

    The description clearly states it 'browses the Lightning-native agent marketplace' and 'lists AI services available for purchase.' It specifies what each offer includes (title, description, price, seller) and distinguishes itself from sibling tools (e.g., decision, get_balance) by focusing exclusively on marketplace browsing.

    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 advises using this tool 'before calling offers_buy' and 'to check the current marketplace inventory,' providing clear when-to-use guidance. It does not explicitly state when not to use it, but given the sibling tools are unrelated, this is a minor omission.

    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?

    Discloses return type (string), JSON parsing requirement, empty string for missing keys, and cost (1 sat/KB min 20 sats). No annotations exist, so description provides good 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?

    Five concise sentences, front-loaded with purpose. No fluff, each sentence adds meaningful 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?

    Covers return behavior, error case (empty string), JSON handling, and cost. For a simple 2-param tool with output schema, it is nearly complete. Minor omission of potential size limits.

    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 covers 100% of parameters with descriptions. Description adds value by reinforcing exact match requirement and directing to memory_list for key discovery, 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?

    Clearly states it retrieves a previously stored memory entry for an agent. Differentiates from sibling tools like memory_store and memory_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?

    Implies when to use (retrieve specific memory) and references memory_list for key discovery, but lacks explicit exclusions or comparison to alternatives.

    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, the description discloses persistence across restarts, cost per KB, minimum fee, and return string. It adds valuable behavioral context beyond basics.

    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?

    Five sentences, front-loaded with purpose, each sentence adds value (persistence, use cases, cost, return). 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?

    Covers persistence, use cases, cost, and return value. Missing error handling or size limits beyond recommendation, but output schema exists. Good for a simple tool.

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

    Parameters3/5

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

    Schema coverage is 100% and schema descriptions are already clear. The description adds little new information about parameters beyond examples; baseline 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 persists a key-value memory entry across sessions, with specific verb 'Persist' and resource 'key-value memory entry'. It distinguishes from siblings like memory_get and memory_list by focusing on storage.

    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?

    Provides explicit use cases like saving trade state or user preferences, but does not mention when not to use (e.g., for retrieval) or explicitly name alternatives.

    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, so description carries full burden. States cost ('Free') and return format ('JSON-formatted list'). As a read operation, no side effects need disclosure. Additional behavioral details (e.g., performance, limits) not needed for this simple tool.

    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 earning its place: purpose, usage hint, cost and return type. No fluff, well-structured.

    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?

    Output schema exists, so return details are covered. Description mentions JSON list format. Missing potential error info or pagination, but for a simple listing tool, it's sufficient.

    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% for the only parameter (agent_id). The description adds value by advising to use this tool before memory_get, which is not in 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?

    Clear verb+resource: 'List all stored memory keys for a given agent.' Distinguishes from siblings memory_get and memory_store by focusing on listing keys only.

    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?

    Explicit usage scenarios: inspect stored keys or check key existence before retrieval. Lacks explicit when-not-to-use, but adequately guides selection among siblings.

    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?

    Discloses it is a free, read-only operation. No annotations existed, so description carries the burden well by stating cost and 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?

    Four sentences, front-loaded with purpose, no wasted words. Structured with sections for cost and returns.

    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?

    Fully complete for a no-parameter tool with output schema described. Provides enough context for an agent to understand what it does and when to call it.

    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, so schema coverage is 100%. Description adds no param info but none is needed. Baseline of 4 applies per guidelines.

    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 verb 'Check' and the resource 'Bearer account balance and remaining complementary calls'. Unambiguous and distinguishes from sibling tools like decision or memory_get.

    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?

    Explicitly advises when to use: to verify sufficient funds before paid calls or to monitor spending. No explicit alternatives, but siblings don't overlap.

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