Server Quality Checklist

67%
Profile completionA complete profile improves this server's visibility in search results.
  • Latest release: v0.3.4

  • Disambiguation5/5

    Every tool targets a distinct resource and action, with clear prefixes (fa_<resource>_<action>) and descriptions that differentiate similar-sounding tools like the three search variants.

    Naming Consistency4/5

    The vast majority follow a consistent verb_noun pattern in snake_case, but a few like fa_foresight_search (noun_verb) and fa_search_flights_advanced (adjective suffix) deviate slightly.

    Tool Count4/5

    33 tools is on the higher side but justified by the breadth of the flight tracking domain; each tool serves a specific purpose without significant redundancy.

    Completeness5/5

    The tool surface comprehensively covers flight tracking: search, current/historical flights, tracks, routes, maps, airports, operators, alerts, and ancillary features like aircraft ownership and scheduled flights.

  • Average 4.1/5 across 33 of 33 tools scored. Lowest: 3.3/5.

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?

    Annotations already declare readOnlyHint=true and openWorldHint=true, covering safety and data volatility. The description adds that routes include aircraft types, counts, and altitudes, but omits paging behavior, response size 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.

    Conciseness4/5

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

    Single sentence with no redundancy. However, it could be slightly expanded to include key return elements without becoming verbose.

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

    Completeness2/5

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

    The tool has 4 parameters, paging (cursor, max_pages), and no output schema. The description does not explain how paging works, what the response structure is, or how many routes are returned. This is insufficient for an agent to use correctly without additional inference.

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

    Parameters3/5

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

    Schema coverage is 100%, so the description adds no extra parameter meaning beyond what the schema already provides. Baseline 3 is appropriate.

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

    Purpose4/5

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

    The description clearly states the tool gets popular routes with aircraft types, counts, and filed altitudes between an origin and destination. It distinguishes from siblings like fa_get_airport_flights or fa_get_flight_route, though not explicitly.

    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 vs alternatives. Does not mention when not to use, prerequisites, or context where another tool might be better.

    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?

    Annotations already declare readOnlyHint and openWorldHint. The description adds only that it fetches weather, which aligns but does not disclose additional behaviors like pagination (cursor, max_pages) or response format. With annotations present, the bar is higher for adding context; the description adds minimal behavioral insight.

    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?

    One sentence, zero waste. Efficiently captures the tool's purpose without unnecessary detail.

    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 absence of an output schema, the description fails to clarify the response structure or pagination behavior. It mentions data types but lacks completeness for a 4-parameter tool. Adequate but has clear gaps.

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

    Parameters3/5

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

    Schema description coverage is 100%, with each parameter documented. The description adds little beyond the schema; it only reiterates the report enum values ('observations' vs 'forecast'). Baseline is 3 for high coverage, and no substantial extra meaning is provided.

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

    Purpose5/5

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

    The description clearly states the tool gets weather for an airport, specifying both current METAR observations and TAF forecast. It uses specific verbs and resources ('Get weather', 'METAR', 'TAF'), and distinguishes from sibling tools like fa_get_airport and fa_get_airport_delays.

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

    Usage Guidelines3/5

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

    No explicit guidance on when to use this tool versus alternatives. While the description implies it is for weather data, it does not mention when to choose observations vs forecast, or when to use sibling tools like fa_get_airport_delays.

    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?

    Annotations already declare readOnlyHint and openWorldHint. Description adds 'breadcrumb log' implying a sequence, but does not disclose limits, pagination, or behavior when data is missing. No contradictions.

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

    Conciseness5/5

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

    Single sentence, no wasted words, front-loaded with purpose. Highly concise and structured.

    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 schema coverage and annotations, description is adequate but lacks usage guidance and details about return format. Minimal but not insufficient.

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

    Parameters3/5

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

    Schema coverage is 100%, descriptions already present for both parameters. Description does not add further meaning beyond what schema provides. Baseline 3.

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

    Purpose5/5

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

    The description clearly states the verb 'Get', the resource 'position track (breadcrumb log)', and the identifier 'fa_flight_id'. It distinguishes from siblings like fa_get_flight_position and fa_get_flight_route.

    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 fa_get_flight_position or fa_get_flight_route. Siblings are listed but no exclusions or context provided.

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

  • Behavior3/5

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

    Annotations already provide readOnlyHint and openWorldHint. Description adds the paging behavior and cursor usage, but does not reveal additional behavioral traits such as rate limits, data freshness, or response structure. This is adequate given the simple read-only nature.

    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 short sentences, front-loaded with purpose. Every word is functional with no redundancy. Excellent conciseness.

    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?

    Description covers the core purpose and paging, but omits what data is returned (e.g., airport codes, names) since no output schema exists. For a simple list tool, this is minimally adequate but could be improved with a brief note on response content.

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

    Parameters3/5

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

    Schema coverage is 100%, with detailed descriptions for both cursor and max_pages (including billing context). The description only adds 'Use the cursor to page through', which does not surpass the schema's own semantics. 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?

    Description clearly states 'List airports known to AeroAPI' with verb 'List' and specific resource 'airports'. It distinguishes from sibling fa_get_airport by implying a collection rather than a single item. The mention of paging clarifies the scope.

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

    Usage Guidelines2/5

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

    Description lacks explicit guidance on when to use this tool vs alternatives like fa_get_airport (for single airport). It only provides paging instructions ('Use the cursor to page through'), but no context on selection criteria or exclusions.

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

  • Behavior2/5

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

    Annotations already declare readOnlyHint=true and openWorldHint=true, so the description does not need to repeat those. However, the description adds no further behavioral details such as paging behavior, rate limits, or that the radius is in statute miles (already in schema). No contradiction with 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 a single sentence that is front-loaded and contains no filler. Every word is necessary to convey the core purpose.

    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?

    The tool has moderate complexity with 6 parameters and no output schema. The description adequately explains the basic operation, but it omits mention of paging (cursor parameter) and the max_pages limitation, which are relevant for a complete understanding.

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

    Parameters3/5

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

    All 6 parameters have descriptions in the input schema (100% coverage), so the description does not need to add parameter-level detail. It provides a high-level context but no additional meaning beyond what the schema already offers.

    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 specifies the verb 'Find', the resource 'airports', and the key constraints: near a latitude/longitude and within a radius in statute miles. This clearly differentiates it from sibling tools like fa_get_airport, fa_list_airports, and fa_resolve_airport.

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

    Usage Guidelines3/5

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

    The description implies usage when needing airports near a location, but it does not explicitly state when to use this tool versus alternatives (e.g., fa_list_airports for listing all airports or fa_get_airport for a specific airport). No guidance on when not to use it.

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

  • Behavior3/5

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

    Annotations already indicate read-only and open world behavior. The description adds date range and filter context, but does not mention pagination behavior, cost implications (capped pages), or data freshness, slightly beyond 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?

    Single clear sentence with no superfluous words, effectively front-loaded with key action and scope.

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

    Completeness2/5

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

    For a tool with 9 parameters and no output schema, the description lacks details on pagination (cursor, max_pages), return structure, or usage prerequisites, leaving significant gaps for proper invocation.

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

    Parameters3/5

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

    Schema coverage is 100%, so parameters are well documented in the schema. The description adds no new parameter semantics beyond listing some filter fields, meeting baseline expectations.

    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 retrieves airline-scheduled flights between two dates with optional filters, using specific verb 'Get' and resource 'scheduled flights', and distinguishes from many sibling tools that handle other flight data like tracks or history.

    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 scheduled flight lookups in a date range, but does not explicitly differentiate from similar tools like fa_get_flights or fa_search_flights, nor provides when-not-to-use guidance.

    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?

    Annotations already declare readOnlyHint=true and openWorldHint=true, so the description does not need to restate them. It adds no additional behavioral context (e.g., data freshness, rate limits), but does not contradict the 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 a single, well-structured sentence that conveys the essential information without any unnecessary words. It is appropriately front-loaded and concise.

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

    Completeness5/5

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

    For a simple tool with one parameter, no output schema, and read-only semantics, the description is fully complete. It provides all necessary information for an agent to use the tool correctly.

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

    Parameters3/5

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

    Schema description coverage is 100%, and the description includes the same example 'N12345' as the schema. Beyond echoing the parameter's purpose, it adds no new semantic value, meeting the baseline expectation.

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

    Purpose5/5

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

    The description clearly states the action ('Get'), the resource ('registered owner of an aircraft'), and the input method ('by tail number / registration'), with a concrete example. It effectively distinguishes itself from sibling tools like fa_get_operator.

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

    Usage Guidelines2/5

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

    The description provides no guidance on when to use this tool versus alternatives. With many sibling tools for different lookups, the absence of usage context or exclusions leaves the agent without direction.

    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?

    Annotations already declare readOnlyHint and openWorldHint. The description adds no behavioral details beyond the parameter descriptions, such as data freshness or pagination behavior, which are partially covered by parameters. No contradiction.

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

    Conciseness5/5

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

    The description is a single concise sentence that front-loads the purpose. Every word earns its place.

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

    Completeness3/5

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

    With 7 parameters and no output schema, the description could be more complete about return values (e.g., listing flight details). However, parameter descriptions cover time window and pagination, making it adequate for a read-only list 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 each parameter is already documented. The description adds minimal value beyond what the schema provides, e.g., explaining the board enum which is also in the schema.

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

    Purpose5/5

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

    The description clearly states the verb 'Get' and resource 'flight board for an airport', and lists specific board types. This distinguishes it from sibling tools like fa_get_airport_flight_counts and fa_get_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 provides clear context on what boards can be fetched but does not explicitly mention when to use this tool versus alternatives, nor any when-not-to scenarios.

    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?

    Description adds 'Returns recent, current, and scheduled flights' beyond annotations (readOnlyHint, openWorldHint). Does not contradict annotations. However, missing details on pagination and rate limits.

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

    Conciseness5/5

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

    Single sentence, front-loaded with purpose, no extraneous wording.

    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?

    Description covers core function but is vague on return format and optional time-window parameters; given no output schema, more detail would be helpful.

    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 parameter coverage is 100%, so baseline is 3. Description adds value by elaborating on 'ident' types, but repeats some schema-provided information.

    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 'Get flights for an ident' and explains valid ident types (designator, registration, fa_flight_id), distinguishing it from sibling tools like fa_get_flight_history or fa_get_flight_position.

    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; lacks context about exclusions or prerequisites.

    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?

    Annotations already declare readOnlyHint=true and openWorldHint=true, so the description's value is limited. It adds the behavioral trait 'current' implying real-time data, but does not disclose other traits like latency, rate limits, or response size. It does not contradict 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 highly concise at one sentence with a clear front-loaded purpose, no redundancy, and efficient use of words.

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

    Completeness2/5

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

    Given the absence of an output schema and the tool's three parameters (including pagination), the description is insufficiently complete. It does not explain the return format, cursor usage, or max_pages behavior, leaving the agent underinformed for correct invocation.

    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 all parameters described, so baseline is 3. The description adds extra value by explicitly highlighting the key 'id' parameter usage ('when `id` is given'), though it omits mention of 'cursor' and 'max_pages'.

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

    Purpose5/5

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

    The description clearly states the tool retrieves 'current airport delays' and distinguishes two modes: all delays or a single airport when 'id' is provided. This specificity differentiates it from sibling tools like fa_get_airport (general info) or fa_get_airport_weather.

    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 offers a basic usage condition ('or just one when `id` is given') but provides no explicit guidance on when not to use this tool or alternatives among the many sibling tools. The usage context is implied but not fully articulated.

    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?

    Annotations already provide readOnlyHint and openWorldHint. The description adds that the route is 'decoded', implying processed data, but does not disclose other behavioral traits like data source, update frequency, or limitations. Minimal additional transparency beyond 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 a single concise sentence with no fluff. It front-loads the action and resource, making it efficient for an AI agent to parse.

    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 simple one-parameter tool and annotations covering safety, the description is mostly complete. However, it lacks explanation of the return format or what 'decoded route' entails, which could be useful for an agent comparing with other flight tools.

    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 for the single parameter 'id', which is already described as 'fa_flight_id of the flight'. The description repeats this without adding new semantics, so baseline 3 is appropriate.

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

    Purpose5/5

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

    The description clearly states the verb 'Get', the resource 'decoded route (fixes/waypoints)', and the key parameter 'fa_flight_id'. It distinguishes from sibling tools that focus on alerts, searches, or other flight aspects.

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

    Usage Guidelines3/5

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

    The description implies usage when a flight ID is available but does not provide explicit guidance on when to use this tool versus siblings like fa_get_flight_track or fa_get_flight_history. No exclusion criteria or alternative suggestions are given.

    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?

    Annotations already declare readOnlyHint=true and openWorldHint=true. Description adds context about board types but does not mention billing (max_pages capped at 20), pagination, or any rate limits. With annotations covering safety, a 3 is appropriate.

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

    Conciseness5/5

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

    Single sentence, front-loaded with key information. No superfluous 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?

    Adequately describes purpose and board types. Missing mention of pagination (cursor) and billing implications (max_pages cap) which are in schema but not in description. For a tool with 4 params and no output schema, it is mostly complete.

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

    Parameters3/5

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

    Schema coverage is 100%, so baseline is 3. The description lists board values but adds no new meaning beyond the schema. No elaboration on cursor or max_pages 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?

    Description clearly states verb ('Get'), resource ('flight board for an operator'), and scope ('all flights, or arrivals/departures/enroute/scheduled'). Distinguishes from sibling tools like fa_get_operator (which gets operator details) and fa_get_flights (which likely gets flights without operator filter).

    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 when-to-use or when-not-to-use guidance. While the resource name implies use for operator-specific flight boards, there are many flight-related siblings (fa_get_flights, fa_search_flights, etc.) and no comparison or exclusion of 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?

    Annotations already declare readOnlyHint and openWorldHint. The description adds valuable context about the premium tier subscription leading to 402/403 errors, which is a critical behavioral trait not covered by 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?

    Two sentences: first explains purpose and comparison, second warns about premium tier. Very concise, front-loaded, and every sentence adds value 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?

    The description adequately covers purpose, differentiation, and a key limitation. It lacks details on pagination and return format, but given no output schema and the simplicity of the tool, it is sufficiently complete for an agent.

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

    Parameters3/5

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

    With 100% schema description coverage, the schema already explains all parameters. The description adds minimal extra meaning, only referencing the query language similarity to fa_search_flights_advanced. 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 performs a predictive flight search using a Boolean query language, directly comparing it to the sibling tool fa_search_flights_advanced and distinguishing it by focusing on predicted data.

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

    Usage Guidelines3/5

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

    The description implies usage for predictive data via comparison to fa_search_flights_advanced and warns about premium tier requirements, but does not explicitly state when to use this tool over alternatives or provide exclusions.

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

  • Behavior3/5

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

    Annotations already declare readOnlyHint=true and openWorldHint=true, indicating safe, read-only behavior. The description adds paging context but no additional behavioral disclosures 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?

    Extremely concise: two short sentences that directly convey the tool's purpose and key usage (paging with cursor). 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?

    For a simple list tool with two optional parameters and no required fields, the description is adequate. It mentions paging but does not specify the return format; however, given the lack of output schema, this is 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?

    Input schema has 100% description coverage: both 'cursor' and 'max_pages' are well-documented in the schema. The tool description does not add extra semantic value beyond the schema.

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

    Purpose5/5

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

    The description clearly states it lists operators (airlines) known to AeroAPI, with paging support. It distinguishes itself from sibling tools like fa_get_operator (single operator) and fa_get_operator_flights (flights for an operator).

    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 guidance on paging (cursor usage) and indicates the tool is for listing all operators. While it doesn't explicitly exclude other contexts, the purpose is clear enough for an agent to decide when to use it.

    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 indicate a non-read-only, mutable operation. The description adds critical behavioral details: the dry-run preview when confirm is false, the actual creation when true, and the tier restriction. This goes beyond the schema and annotations, though it doesn't describe rate limits or error states, which would be nice.

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

    Conciseness5/5

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

    The description is two sentences long, with the main action stated first. Every word adds value: the verb, the resource, the confirm behavior, and the tier requirement. No fluff, perfectly front-loaded.

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

    Completeness3/5

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

    For a tool with 15 parameters and no output schema, the description covers the core workflow and a critical authorization note. However, it does not describe the preview format or what the API returns on successful creation. It also lacks details on default behaviors (e.g., what happens if no filters are set). Adequate but could be more complete given the complexity.

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

    Parameters3/5

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

    Schema coverage is 100%, so the schema already describes all 15 parameters. The description adds value only for the confirm parameter by explaining the dry-run behavior. For other parameters, the description adds no extra meaning beyond the schema descriptions. Hence a 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 states the exact action: 'Create a flight alert on your AeroAPI account.' It clearly differentiates from sibling tools like fa_update_alert and fa_delete_alert by focusing on creation. Additionally, it explains the dry-run mode, making the tool's core function unmistakable.

    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 explains the confirm parameter's role (dry-run vs. actual creation) and warns about the required AeroAPI tier. It provides clear context on when to use each mode. Though it doesn't mention alternatives (e.g., updating versus creating), the sibling list makes that implicit, so the guidance is strong but not perfect.

    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?

    Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds the specific fields returned, which is useful but does not discuss behavioral traits like data freshness or authorization needs. No contradiction.

    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?

    One sentence, concise, lists the return fields. No wasted words. Front-loaded 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 a simple parameter and no output schema, the description fully explains what the tool returns in a structured format. Annotations cover safety. Complete for an agent to use correctly.

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

    Parameters3/5

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

    Schema coverage is 100%, with the parameter 'id' described as 'Airport code (ICAO/IATA/LID)'. The description does not add extra meaning beyond the schema, so the baseline of 3 is appropriate.

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

    Purpose5/5

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

    The description clearly states the verb 'Get', the resource 'flight counts at an airport', and lists the specific fields returned: departed, enroute, scheduled_arrivals, scheduled_departures. This distinguishes it from siblings like fa_get_airport_flights (detailed flights) or fa_get_airport (airport info).

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

    Usage Guidelines4/5

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

    The description implies usage for aggregate counts vs. detailed flight data, but does not explicitly state when to use this tool over alternatives or when not to. It's clear enough for an agent to infer.

    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 indicate readOnlyHint and openWorldHint. The description adds important behavioral context: writes PNG to disk with configurable directory, or returns inline base64. It does not contradict annotations since the write is client-side.

    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?

    Two sentences efficiently convey output, behavior, and default directory. Could be slightly more concise, but 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?

    No output schema, but description explains return format (path or base64) and mentions PNG. It lacks error handling details but is adequate for a straightforward image retrieval tool with 6 parameters.

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

    Parameters4/5

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

    Schema covers all 6 parameters with descriptions. The description adds value by explaining the output type (PNG), return mechanism (path or base64), and default output directory logic, complementing the schema.

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

    Purpose5/5

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

    The description clearly states it retrieves a rendered map image (PNG) for a flight using fa_flight_id. This specific verb-resource combo distinguishes it from sibling tools like fa_get_flight_position or fa_get_flight_route.

    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

    Conciseness5/5

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

    Two sentences, front-loaded with the action, and the note is concise. No wasted words.

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

    Completeness3/5

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

    Without an output schema, the description hints at return values but does not fully describe the response. The tier requirement is included, but more detail on output would improve completeness for this 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 description coverage is 100%, so the description adds minor context (e.g., output includes equivalents). This is sufficient but not exceptional beyond the schema.

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

    Purpose5/5

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

    The description clearly states the verb 'resolve' and the resource 'airport code to canonical AeroAPI identifier', distinguishing it from sibling tools like fa_get_airport or fa_list_airports.

    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 the AeroAPI tier requirement (Standard or Premium), informing when to use and when not. It does not mention specific alternatives among siblings, 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.

  • Behavior3/5

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

    Annotations already indicate safe read-only behavior (readOnlyHint: true). The description adds that it returns the 'most recent reported position' for in-air flights, but does not mention behavior when flight is not airborne or no position is available. With strong annotations, the description adds moderate value.

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

    Conciseness5/5

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

    Single sentence, no wasted words. Front-loaded with the essential purpose.

    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?

    Usage Guidelines4/5

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

    Explicitly notes the required AeroAPI tier (Standard/Premium) and that free tier returns 401, guiding when to use. Does not mention alternatives, but the context is clear enough.

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

  • Behavior5/5

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

    Beyond annotations (idempotent, non-read-only), the description discloses the dry-run behavior (no network call without confirm:true) and tier requirement, providing critical behavioral context that annotations alone do not cover.

    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 concise sentences, front-loaded with the core purpose. Every sentence contributes essential information without 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?

    The description covers the tool's core functionality, dry-run mode, and tier requirements. Without an output schema, it could detail what the preview returns, but overall it is sufficiently complete for a delete operation with conditional behavior.

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

    Parameters3/5

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

    Schema coverage is 100% with descriptions for both parameters. The description reinforces confirm behavior but adds little new meaning beyond what the schema already provides, meeting the baseline for high 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 'Delete a flight alert by id,' specifying the verb (delete) and resource (flight alert by id). Among siblings, there are create, update, get, and list alerts, making this tool's delete function distinct and unambiguous.

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

    Usage Guidelines4/5

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

    The description explains the confirm parameter's role in triggering a dry-run vs actual deletion, and specifies the required AeroAPI tier (Standard or Premium) with a 401 error for free tier. It gives clear context for using the tool but does not explicitly compare to siblings like fa_create_alert or fa_update_alert.

    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?

    Beyond annotations (readOnlyHint, openWorldHint), the description adds critical context about API tier requirements and the scope of data (historical beyond recent window). Does not cover pagination but annotations already signal safety.

    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: first defines the core action, second provides a crucial usage note. No wasted 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?

    Covers purpose, scope distinction, and tier requirement. With 6 parameters and no output schema, the description is sufficient but could briefly mention pagination or cursor usage to be more complete.

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

    Parameters3/5

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

    Schema description coverage is 100%, so the baseline is 3. The description does not add parameter-specific meaning beyond what the schema already provides; it only reiterates the ident types.

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

    Purpose5/5

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

    The description clearly states the verb 'Get' and resource 'historical flights', and explicitly distinguishes itself from the sibling tool fa_get_flights by noting it covers data 'beyond the recent window'.

    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?

    Provides explicit guidance on when to use (for historical data beyond recent window) and when not (requires Standard or Premium tier, otherwise returns 401). Implicitly suggests using fa_get_flights for recent flights.

    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=true and openWorldHint=true. Description adds value by specifying acceptable code formats (ICAO/IATA with examples), which is beyond the 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?

    Single sentence, no wasted words, front-loaded with action verb and resource.

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

    Completeness4/5

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

    Given the single parameter, annotations, and sibling tools, the description is sufficient for an agent to select and invoke the tool correctly. No output schema, but purpose is clear.

    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 a clear description of the id parameter. Description adds examples (UAL, UA), providing extra clarity without redundancy.

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

    Purpose5/5

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

    The description uses a specific verb ('Get details') and resource ('operator'), and distinguishes from siblings like fa_list_operators and fa_get_operator_flights by focusing on a single operator by code.

    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 clearly states when to use (get details by code) and implies when not to (if you need list or flights, use siblings). No explicit exclusions but context is sufficient.

    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 indicate readOnlyHint=false, idempotentHint=true, openWorldHint=true. The description adds transparency by explaining that the tool replaces the entire configuration, requires confirm to execute (otherwise dry-run), and requires a paid tier. No contradiction with 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 two sentences with no wasted words. It front-loads the main purpose and then adds crucial usage details (confirm, tier). Every sentence provides necessary 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?

    With 16 parameters (all described in schema) and no output schema, the description covers the essential behavioral context (dry-run, auth). It does not describe the return value, but given the schema richness, it is largely complete.

    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 100% description coverage for all 16 parameters. The description adds value by explaining the confirm parameter's role (dry-run vs. apply) and that the update replaces the configuration. This clarifies the semantics beyond the schema.

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

    Purpose5/5

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

    The description clearly states 'Update an existing flight alert (replaces its configuration).' The verb 'update' and resource 'flight alert' are specific. This distinguishes it from sibling tools like fa_create_alert and fa_delete_alert.

    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 explains the dry-run behavior when confirm:true is absent and the actual update when present. It also mentions the required AeroAPI tier (Standard or Premium, not free Personal). It does not explicitly contrast with 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.

  • Behavior4/5

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

    Discloses that the tool only returns a count, not flights, and explains query syntax. Annotations already indicate readOnly; description adds return type and usage pattern.

    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 plus example, front-loaded with purpose, 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 tool simplicity (one param, no output schema, readOnly annotations), the description fully covers functionality, syntax, and return value.

    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 parameter with description, but description provides concrete example and clarifies the syntax is same as fa_search_flights, adding value beyond schema.

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

    Purpose5/5

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

    Description uses specific verb 'count' and resource 'flights', clearly states it returns a count without returning flights, and distinguishes from search tools by syntax reference.

    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 mentions the syntax (simplified -key value) and contrasts with fa_search_flights_advanced, giving guidance on when to use this tool. Could be improved by stating 'when only count needed'.

    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 'readOnlyHint: true' and 'openWorldHint: true' are present. The description adds context about billing (capped at 20 pages) and query string limits (1000 bytes), going beyond the 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 a single paragraph that concisely explains the tool's purpose, syntax, and example. Every sentence adds value, with no unnecessary words.

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

    Completeness4/5

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

    While there is no output schema, the description covers pagination via cursor and max_pages. It lacks details on response structure, but given the tool's simplicity and the presence of sibling tools for more detailed flight data, this is acceptable.

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

    Parameters5/5

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

    Schema covers all parameters with descriptions (100% coverage). The description adds significant meaning by explaining the query syntax, listing valid keys, and providing an example. It also clarifies the billing implication for max_pages.

    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 airborne flights using AeroAPI's simplified query syntax', specifying both the resource and method. It distinguishes itself from the sibling 'fa_search_flights_advanced' by emphasizing the simplified syntax.

    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 explains the query syntax and provides an example, making it clear when to use this tool for simple queries. However, it does not explicitly state when not to use it (e.g., for complex queries, use the advanced version).

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

  • Behavior5/5

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

    Annotations already mark it as read-only and open-world. The description adds substantial behavioral details: query language syntax, paging via cursor and max_pages with a billing cap, and operator explanations. No contradictions.

    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 dense yet efficient, covering many details in one paragraph. It could benefit from more structured formatting (e.g., bullet lists) but is still clear and concise.

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

    Completeness3/5

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

    The description thoroughly explains query usage and paging but omits the return format or response structure. Since there is no output schema, this gap reduces completeness for an agent needing to process results.

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

    Parameters5/5

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

    Schema coverage is 100%, but the description greatly enhances understanding of the complex 'query' parameter with detailed syntax, operators, keys, and an example. This adds significant value beyond the schema.

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

    Purpose5/5

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

    The description clearly states the tool searches flights using a structured query language, explicitly distinguishing it from fa_search_flights as more expressive. The verb 'Search' and resource 'flights' are specific, and the example solidifies the purpose.

    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 this tool is for advanced querying compared to fa_search_flights, providing an example and listing operators and keys. However, it lacks explicit guidance on when not to use it or detailed alternatives, slightly reducing clarity.

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

  • Behavior5/5

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

    Annotations indicate readOnlyHint and openWorldHint; description adds that returns position points rather than flight summaries, and explains paging via cursor and max_pages cap due to billing, providing additional 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 concise sentences: first covers purpose and usage, second clarifies return type and gives example. 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 3 parameters (1 required) and no output schema, description explains return type and paging. Missing details on position point structure, but sufficient for agent understanding.

    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 the query language and example for 'query', and billing context for 'max_pages' cap, exceeding basic schema info.

    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 searches flight positions using a structured query language, and distinguishes itself from the sibling tool fa_search_flights_advanced by specifying the grammar and return type.

    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?

    It explicitly describes the query language format, contrasts with the simplified syntax of another tool, and provides an example, giving clear when-to-use guidance.

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

  • Behavior5/5

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

    Annotations already indicate readOnlyHint=false, idempotentHint=true, and openWorldHint=true. The description enriches this by detailing the dry-run vs. apply behavior, absence of network call without confirm, and auth restriction (401 on free tier). No contradictions with 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?

    Two sentences: the first front-loads the core action, the second adds critical behavioral details. No superfluous words. Perfectly structured.

    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 no output schema, the description still mentions return behavior (dry-run preview). Auth requirement is covered. With idempotentHint and openWorldHint from annotations, the description provides sufficient context for an agent to use the tool correctly.

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

    Parameters4/5

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

    Schema coverage is 100%, so baseline is 3. The description adds value by explaining the url parameter's role (AeroAPI POSTs to it) and the confirm parameter's necessity for actual change. The format parameter's options are covered by the schema, but description adds context on delivery payload format. Marginal but useful enhancement.

    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 sets the webhook endpoint for alert notifications, distinguishing it from siblings like fa_get_alerts_endpoint (retrieves) and fa_create_alert (creates alerts). The verb 'set' and resource 'delivery endpoint' are specific and unambiguous.

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

    Usage Guidelines5/5

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