  • Latest release: v0.1.0

  • Disambiguation5/5

    Each tool has a distinct purpose: finding airports, exploring cheapest dates, and searching specific flights. No overlap.

    Naming Consistency5/5

    All tool names follow a verb_noun pattern with consistent verb choices (find/search), making them predictable.

    Tool Count4/5

    With only 3 tools, it's slightly minimal but covers the core flight search workflow without unnecessary bloat.

    Completeness5/5

    The tool set covers the full flight search lifecycle: locate airports, find optimal dates, and retrieve specific flights. No obvious gaps.

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?

    Annotations already declare readOnlyHint=true and idempotentHint=true. The description adds that it returns a list of dates with prices, which is consistent, but does not disclose additional behavioral traits like rate limits or data freshness.

    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, front-loaded with main purpose, no extraneous words. Highly efficient.

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

    Completeness4/5

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

    Given rich schema (100% coverage), annotations, and output schema, the description adequately covers core functionality and return values. Could mention more about filtering options or result format nuances.

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

    Parameters3/5

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

    Schema coverage is 100%, so baseline is 3. The description only adds context about one-way/round-trip searches, which is already covered by the is_round_trip parameter schema.

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

    Purpose5/5

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

    The description clearly states the verb 'find' and resource 'cheapest travel dates between two airports within a date range', differentiating from sibling tools find_airports and search_flights.

    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 flexible travel planning and notes support for one-way/round-trip, but does not explicitly guide when to use this tool versus search_flights or provide exclusions.

    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?

    Annotations already declare readOnlyHint and idempotentHint as true, so the description's mention of returning a list of flights is consistent. It adds useful context about return fields (prices, durations, leg details) and trip types (one-way, round-trip), going beyond what annotations provide.

    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, front-loading the core purpose. Every sentence adds value: the first states the action, the second describes the output, the third notes supported search types and filters. 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 complexity (15 parameters, output schema exists, annotations provided), the description sufficiently covers the main purpose and return format. It does not detail the output schema structure, but that is handled by the output schema itself. Minor gaps in pagination or rate limits are acceptable.

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

    Parameters3/5

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

    Schema coverage is 100%, meaning all 15 parameters have descriptions in the schema. The description adds no extra parameter-specific meaning beyond referencing 'various filtering options,' so it meets the baseline without exceeding.

    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 'Search for flights between two airports on a specific date,' specifying the verb (search), resource (flights), and scope. Sibling tools find_airports and search_dates handle different tasks (airport lookup and date exploration), so this tool is well-distinguished.

    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 does not explicitly state when to use this tool versus alternatives like search_dates. It implies usage for flight search with filtering, but lacks explicit guidance on when not to use or when to consider other 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?

    Annotations already indicate readOnlyHint and idempotentHint, confirming safe read operation. Description adds behavioral context by explaining supported query types and providing examples, without contradicting 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?

    Three concise sentences: purpose, usage guidance, and examples. Every sentence adds distinct value with no redundancy.

    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?

    Input schema fully described, output schema exists, annotations cover safety. Description covers all user-facing aspects including query types and use case, making it complete for a simple lookup tool.

    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% with descriptions for both parameters. Description adds value by offering examples for 'query' (e.g., 'new york', 'heathrow', 'JFK') and clarifying search functionality beyond schema descriptions.

    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 'Search for airports' and specifies three distinct input types (city name, airport name, IATA code). Differentiates from sibling tools search_dates and search_flights by focusing on airport lookup for flight context.

    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 using this tool before searching for flights to find IATA codes. Provides clear usage context but does not include when-not or alternative scenarios.

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